Mini boiler room zota 6 instructions on how to connect correctly

Today, heating equipment is a common means of heating rooms of various sizes. We are talking about both residential premises and industrial buildings.

Today, many different companies are engaged in the manufacture of electric boilers. Their products differ in many ways, from the quality of each part to service life. Depending on the room for which the device is intended, it is necessary to choose a manufacturer.

Zota electric boilers are manufactured for heating rooms with a total area of ​​30 to 400 square meters. They are developed taking into account the wishes of each consumer and are focused on the Russian buyer.

Features of single- and double-circuit boilers

When thinking about how to choose the right heating boiler for your home, special attention should be paid to such a characteristic as the number of circuits. Single-circuit technology is intended exclusively for heating the coolant circulating through heating pipes. In this case, to heat tap water you will have to additionally install a boiler.

Yes, a single-circuit boiler is convenient, but the disadvantage of this solution is its high cost - you will have to buy not only heating equipment, but also a boiler. Moreover, both devices will take up a lot of space

In this case, to heat tap water you will have to additionally install a boiler. Yes, a single-circuit boiler is convenient, but the disadvantage of this solution is its high cost - you will have to buy not only heating equipment, but also a boiler. Moreover, both devices will take up a lot of space.

As for the double-circuit boiler, here the heating equipment and water heater are assembled into a single structure. Thanks to this structure, you can solve two problems at once, while purchasing only one unit.

In addition, in the absence of hot water, the coolant can be redirected to the second circuit and used alternately - to heat the house and to provide hot water supply.

Operating principle of single-circuit equipment

Single-circuit heating equipment is most often used by owners of luxury country houses. In essence, a single-circuit boiler is the same water heater, but supplies water to the heating system.

The operating principle of this type of equipment is based on burning fuel in a special compartment and heating the liquid. The heating main is connected to the outlet where the hot coolant enters. Next, the water begins to circulate through the pipes and heat the rooms.

The final stage of circulation is the flow of waste coolant back into the boiler through the inlet pipeline.

If you do not need to provide hot water supply, then it is better to give preference to single-circuit boilers

The cost of a single-circuit boiler may be more than a double-circuit system. Even despite less functionality, this type of equipment is less expensive to install, easier to operate and more energy efficient.

Single-circuit equipment is suitable for those buyers who want to spend money once and buy reliable equipment that does not require special care. This type of boiler will be the ideal and only right choice when there is no need for hot water supply in the house.

Design specifics of a dual-circuit unit

A double-circuit boiler is a system where, in addition to the primary heat exchanger, there is an additional one designed to heat water and then supply it to the water supply system. The movement of the coolant is controlled using a three-way valve. It directs the heated water either to the DHW circuit or to the heating system.

It should be noted that in the first case, the coolant will be supplied only if the hot water tap has been opened. The peculiarity of such heating equipment is that while the tap responsible for supplying hot water is open, the system does not work.

If you have a large family and some of its members like to take long showers, then the rooms may become cool. Manufacturers solve this problem by installing a storage water heater in their boilers.

The disadvantages of the double-circuit boiler design include the need for careful and attentive maintenance. This is due to the fact that the secondary heat exchanger can become overgrown due to the use of water containing organic and mineral particles suspended in it, and the small diameter of the pipes.

If you plan to actively consume hot water, then installing a double-circuit boiler is not the best solution. After all, then the house will not be heated well. You should only think about installing this system in a small house or apartment, where there is not enough space to organize a full-fledged boiler room.

Features of Zota electric boilers and product range

When producing the Zota electric boiler, the manufacturer does everything possible to ensure that the products maintain their brand, are of high quality, in demand, and modern. That is why this Russian company currently occupies a leading position in the heating devices market. The units produced are reliable, economical, almost all have a remote control function, and they meet the requirements of modern standards.

The Zota brand produces heating equipment for buildings for various purposes, including country houses, industrial premises, administrative buildings, warehouses, etc.

Buyers have a choice among five model series.

Let's take a closer look at these lines:

1. Zota Economy. This line is represented by simple electric boilers designed for heating various types of buildings. Low-power options are perfect for installing a heating system in the house. The standard boiler kit has a remote control, which provides automatic temperature control. Zota electric boilers are simple, but they have a self-diagnosis system. For greater reliability and extension of the operating period, the manufacturer added rotation systems for power units and tubular electric heaters to the units.
2. Zota Prom. This is a line of fairly powerful heating devices that are designed for heating large buildings. They are also used to connect the hot water supply circuit. All modifications are installed on the floor and have automatic systems. According to reviews from owners, Zota Prom electric boilers have a long service life. As the manufacturer confirms, this is due to the rotation system of tubular electric heaters. The unit is controlled using remote controls.

Electric boilers ZOTA Prom

Zota Smart. This line is characterized by the presence of sophisticated electronic controls. The models are equipped with automation systems, weather-sensitive sensors, heating and pump control systems, and self-diagnosis systems. All Zota Smart models that can be found on the market have built-in GSM modules for remote control. Tubular electric heaters in the design of heating devices are made of high-quality stainless steel, there are many sensors, ports for control and circulation pumps.

Model 2014 ZOTA Smart

Zota MK. This includes not simple boilers, but mini-boiler rooms. They are distinguished by the presence of a built-in piping - inside there is a 12-liter expansion tank, a circulation pump and a safety group. The Zota MK electric boiler is controlled using a built-in remote control; new models have the ability to install GSM modules. The boilers in this line are small and neat in design.

Zota 12 MK

The devices are characterized by a long service life and modern functional equipment.

The lineup

So, in the model line of Zota electric boilers there are five models:

Economy model

This is the cheapest model, but in terms of operational and technical characteristics it is not inferior to any other model. This is a fully automated design with a remote control panel. Boilers can be installed in heating systems with natural and forced movement of coolant.

A distinctive feature is that the boiler and process control unit are located in different buildings. They are installed separately and connected by wires. It should be added that Zota economy class boilers with a power of 3-15 kW can operate both from power relay installations and from standard magnetic starters.

The automation of the heating device makes it possible to regulate the temperature in the range from +40C to +90C. These are the optimal limits that allow you to adjust the mode to save fuel consumption

Note:

• Economy class Zota boilers with a power of 3-15 kW are manually adjusted.
• Units with a power of 18-45 kW are configured automatically.

All boilers of this model are equipped with a self-diagnosis system. This makes it possible to identify flaws in thermal processes and breakdowns of components and parts in advance.

Lux

The Lux model is considered the most popular and popular. It is intended for heating houses with an area of ​​30-1000 m². This is a fully automated electric unit that is improved every year, acquiring new options and functions.

All boilers of this model are equipped with block heating elements made of stainless steel tubes. The most advanced automation has been installed, allowing for good savings on fuel consumption.

MK

These are mini boiler rooms, which include:

• Electric boiler with characteristics similar to the Zota Lux boiler.
• Power block.
• Control block.
• Expansion tank of membrane type.
• Circulation pump.
• Security block.
• Pipe junction with shut-off valves.

And all this in one building. What does this mean in practice?

• Firstly, due to the compactness of the device, mini boiler rooms do not require a large installation space.
• Secondly, this configuration allows you to save on additional materials.
• Thirdly, it is easy to install. Here you just need to connect to the power supply network and connect the pipes to the circuits of the heating system of the house.

Let us add that Zota MKs are produced with a power from 3 kW to 36 kW. For small country houses, this is the best option for heating.

Features of Zota electric boilers

The Zota company produces several models of electric boilers. Some of them are extremely popular, while others are rarely purchased. Let's look at the line of electric boilers.

Zota boiler line

There are 6 models of Zota electric boilers. Among those in demand are:

The Zota Smart electric boiler is equipped with a special heating element, thanks to which it functions successfully. The power of the equipment is less than that of the Lux model.

The system consists of the following elements:

1. Expansion tank.
2. Circulation pump.
3. Special protection against overheating.

An electric boiler can be used in a heating system with a pressure of 6 atm. The Smart model is equipped with an Internet connection. In addition, the entire system is automated and depends on weather conditions. You can use the Internet to control the electric boiler.

The electric boiler Zota Economy has a remote control unit for the equipment. The device can be installed anywhere in the house. To control the boiler, you can use the control panel, which works as a magnetic starter.

This model has been manufactured for economical use. To operate such equipment, a minimal amount of electricity is consumed. For this purpose, transmission stages are installed in the electric boiler. They operate automatically, so you do not have to constantly monitor the operation of the equipment.

The Zota Prom electric boiler is of a floor-standing type. Such a unit is used for household premises. In 1 hour, the equipment produces 9 m 3 of hot water. The electric boiler is equipped with a control unit with programs for autonomous operation of the device. The unit can work independently without human intervention.

Electric boilers Zota Lux

The Zota Lux electric boiler has an additional safety mixture. Thanks to it, the unit is protected from sudden voltage surges. You can set the required power yourself.

Two circuits can be connected to an electric boiler if necessary. To do this, you do not need to use additional fittings to regulate the equipment.

Zota Lux electric boilers have many advantages:

1. Using keys, you can change the heating element unit, since access to them is open.
2. Small dimensions and weight of the equipment.
3. Sound equipment.
4. High performance.
5. You can connect a two-phase meter.
6. Using a special pump you can reduce energy consumption.
7. You can save settings in the menu.
8. An error code is displayed on the screen, the explanation of which can be found in the instructions.

This model is used more often than previous ones. The Zota Lux electric boiler is suitable for country and country houses, as well as for other premises.

Electrical installation in a three-phase network

The diagram for connecting an electric boiler to a three-phase network is more complex, but even a beginner can do it.

The three phases must be connected as follows:

Please pay attention to the following nuances:

1. Each water heater comes with a technical passport, which must indicate the manufacturer’s recommended wiring diagram for the electric boiler. Be guided only by this document in your case, because... The examples provided on the Internet may not always be suitable for your heating system.
2. Be sure to protect the boiler and... These devices will prevent overload of the unit, short circuit and current leakage in the electrical network.
3. The wiring must be grounded.

Zota electric boilers are produced at the Krasnoyarsk Heating Equipment and Automation Plant. They have been known to the Russian market for quite a long time, so we can say with confidence that buyers have already become convinced of their reliability and quality. The manufacturer produces boilers of both economy class and luxury class. By and large, the former are in no way inferior in quality to the latter.

In the article we will consider the range of these boilers, their most popular models, the connection of these heating devices, operating rules and, of course, we will touch upon the reviews of the owners.

Electric boiler wiring diagram

Typically, the wiring diagram for an electric heating boiler includes the following additional elements:

• circular pump;
• pressure gauge;
• balancing valve;
• distribution valve;
• valves;
• Ball Valves;
• pass filter;
• valves – through, air, check and safety;
• clamps, couplings, tees;
• heating radiators (batteries);
• coolant pipes - metal or metal-plastic;
• fasteners.

For installation you will need:

• set of wrenches;
• welding machine;
• grinder and other tools.

Also, the heating circuit from an electric boiler includes elements intended for connecting wall-mounted appliances to a heating structure, which can be intended for standard space heating, for hot water supply or for a heated floor system (for more details: “Which electric boiler is best to choose for a heated floor”).

The single-circuit heating arrangement is simple; you just need to follow the instructions for installing the electric boiler. In the case of using a double-circuit system, the connection diagram for the electric boiler can be direct or mixing. In the direct version, the heating temperature is adjusted using a burner. In the mixing circuit, not only a burner is used for these purposes, but also a mixer with a servo drive.

In dual-circuit systems, it is mandatory to use an emergency piping circuit to protect equipment from unforeseen situations, for example, when the power supply is cut off. The most effective way is considered to be the creation of a special emergency circuit.

Boiler piping options, see examples in the video:

Choosing a place to install a thermal electric generator

It is best if the installation of an electric heating boiler is carried out in a non-residential area. The kitchen would be an excellent place for these purposes. For the generator, it is necessary to choose a place that will be convenient both for installation and for its maintenance.

If you install the generator in accordance with the standards, then it is necessary that at least 5 cm of free space remain from its sides to the wall. There must be a free space of at least 70 cm in front of the device, at least 80 cm above the device, and at least 50 cm below it.

The heat generator should only be installed on a wall that is made of non-combustible material. To hang the device, you must use a special mounting strip. Such an element should be included in the basic package of the device. The plank must be attached to the wall using 4 dowels.

If a membrane-type expansion tank is installed in the device, then the heating system is designed for a volume of no more than 500 liters.

The heating connection diagram for an electric boiler implies that another membrane-type pressure compensator will need to be installed in a larger heating system.

Alternative solution

Heat pump

Another heating source is a heat pump. The principle of its operation is similar to that of a conventional refrigerator. The compressor compresses the refrigerant, releasing excess heat into the condenser—it warms your home. In the condenser, gaseous freon turns into a liquid state. After the heat exchanger, it passes through an expansion valve and evaporates with a sharp drop in pressure. With sudden evaporation, the temperature of the heat exchanger drops to a very low level. Since the heat exchanger lies in the ground or on the street, it begins to take away heat from the environment. After the refrigerant turns into a gas in the evaporator, it returns to the compressor and a new cycle begins.

If we consider this solution in terms of efficiency, then it can rightfully be called the best, but with a bunch of reservations. To this day, heat pumps are quite expensive. Air heat pumps do not work in severe frosts, and not all residents have the opportunity to install geothermal

You can choose it as the main source of heat, but it is important to understand that its payback period is quite long

Convectors

In appearance, convectors are very similar to ceramic panel heaters, but inside the metal case there is an “open” heating element enclosed inside a plate radiator. The fundamental difference is in the heating method - cold air enters the case through the bottom row of holes, comes into contact with the radiator, heats up and exits through the top row of holes.

Stylish convector panel looks great in a modern interior Source

Like ceramic panel heaters, there are two types of thermostats - mechanical and electronic. And it is the electronic control of the work that ensures the accuracy of adjustment and the ability to work in several modes:

Electric boilers of the Zota Lux series

- the most popular model today. It is used for heating or, an important feature, separately for a heated floor system without additional control fittings, since there is a built-in ability to regulate the coolant temperature from +30 to +90 degrees. More features:

1. Rotation of heating elements;
2. Extended input voltage range and short-term protection of the control unit from power surges;
3. Weather-dependent regulation;
4. Control of the circulation pump of the heating system;
5. You can connect a GSM module for remote control.

The model range produced by the plant allows you to heat rooms with an area of ​​30 to 1000 sq.m.

Popular Zota boiler models

Electric boiler Zota Economy

The most popular model to this day remains the Zota 6 kW Economy electric boiler. This is a fairly simple model that is installed on the wall and controlled using a remote control (purchased separately). The boiler can operate from both single-phase and three-phase networks. The difference between Zota 6 Economy is three-stage power control, electronic control and overheating protection. If desired, you can equip a heating system with warm floors. The power of the model is suitable for heating an area of ​​60 m².

No less popular boilers are Zota 7.5 Lux, Zota 9 Lux, Zota 12 Lux. The power of the models is indicated in the numerical indices of the listed boilers. All options are designed for heating only and are equipped with electronic control. Built-in programmers, self-diagnosis and security systems are available. Models can also be connected to underfloor heating systems and room thermostats. Modular control possible.

Modifications with a power of 7.5 and 9 kW can operate from single-phase networks, while the Zota 12 kW Lux electric boiler operates only from a three-phase network. The reason is high power consumption.

It is impossible not to mention the Zota electric boiler, reviews of which are always only positive. More precisely, this is a mini-boiler room model Zota 12 MK. It is designed to heat houses and buildings up to 120 m². A small boiler room has programmers, a safety group, a circulation pump and security systems. Operates from a three-phase power supply network. More modern models (after 2012) have the ability to use GSM.

Important features of the boiler operation

The GSM module can be built into all Zota models. It is not included in the standard equipment of the boiler, so it will have to be purchased separately. Installation and launch of the module is also ordered. The remote control can be installed in any room.

According to reviews from owners, Zota electric boilers are characterized by the following features of use:

1. Calculation of the boiler by area. Often, electricity is overused precisely because the device’s performance was calculated incorrectly. The power calculation must be 10-15% greater than the actual need. Excessive supply causes the boiler to overheat and often blow out plugs in the room.
2. Service maintenance. You cannot connect the GSM module yourself. To connect to the electrical network, you will also need to call a specialist. The service worker will also install the air temperature sensor. From time to time you will have to adjust the water sensor for hot water supply.

Line of heating equipment

Our catalog contains the following types of devices:

• Econom - inexpensive models for houses up to 30-480 sq.m.
• Smart is the most technologically advanced model in the ZOTA family of electric boilers;
• MK - miniature boiler rooms in one building for rooms from 30 to 350 sq.m.
• Lux is small-sized equipment with automation, temperature sensors and many other options.
• Balance - balanced product models, characterized by high versatility and low cost;
• Prom is the most powerful series of units for heating rooms up to 4000 sq.m.

Models of electric heating boilers Zota MK, Smart, Econom and Lux ​​have an automatic power control function. This makes it possible to reduce electricity costs by up to 35%. To connect the device to the network, a voltage of 220 V is required. Powerful industrial models require a voltage level of 380 V.

Instructions for use

The attached instructions for the ZOTA electric boiler will allow you to quickly complete installation and carry out initial setup. Before connecting the boiler, preparatory work is carried out. If the device’s power is more than 3 kW, a separate electrical line is laid to it. It is not necessary to install an RCD, since almost all models have it (if not, select a machine that is suitable in terms of current and voltage).

Heating diagram with ZOTA electric boiler as a heating element.

When choosing a place to install a ZOTA electric boiler, you need to make sure that there is no water vapor or aggressive gases in the room, and that the air temperature is in the range from +1 to +30 degrees. Simple tap water or a special non-freezing liquid is used as a coolant. The boilers are installed strictly vertically. When connecting equipment to the electrical network, it is necessary to provide grounding - it is connected to boilers and pipes.

Installation of ZOTA boilers is carried out according to the attached instructions - maintaining the distance to the ceilings, floors and adjacent walls. The device must be in such a position that there are no obstacles to its cooling (natural ventilation is used here). At the last stage, the boiler is connected to the heating system. Next, a leak test and a test run are carried out.

Remember that the pressure in the heating system should not exceed the parameters specified in the passport. Otherwise, equipment damage may occur.

Installation Rules

Like all types of electric boilers, the Zota brand is available in two variations: floor-mounted and wall-mounted, single-phase and three-phase. The installation rules for single-phase models are simple:

• It is necessary to install the unit itself.
• Connect it to the home heating system.
• Plug it into a power outlet.

The only thing that needs to be done is to run a separate power cable from the distribution panel and install a separate machine. With three-phase analogues it is more difficult. If you are not an electrician, then it is best to leave the installation to professionals. It is both reliable and safe.

Operation of the boiler is quite simple. The instructions contain provisions with which you can easily adjust the device to the desired air temperature parameter. The device will do the rest itself.

A fairly wide range of Zota electric boilers allows you to select the required model exactly to meet the consumer’s requirements. Additional options will help increase ease of use. They, of course, increase the cost of the product, but the quality of work only improves. Therefore, it is worth paying attention to the options and choosing the ones that suit the operating conditions.

Single-phase and three-phase electric boilers

The choice of boiler should be taken responsibly, since you need to take into account all the nuances relating to the electrical service of your home. Electrical lines are not always able to cope with the load that increases after installing the boiler. To avoid such problems, visit the energy sales department you belong to and ask (or ask to calculate) the maximum power they can provide. When calculating the required kilowatts, do not forget about the household electrical appliances in your home.

Scheme of the structure of a single-circuit wall-mounted electric boiler: 1 - electrical cabinet; 2 — control lamps; 3 - temperature controller; 4 — thermometer/pressure gauge; 5 - power switches; 6 - main switch; 7 — expansion tank; 8 - cable entry; 9 - safety valve; 10 - pump; 11 - boiler return line; 12 — plug connection of the control circuit; 13 - safety temperature limiter; 14 — control system fuse; 15 — air valve; 16 — boiler lining with thermal insulation; 17 — water pressure switch; 18 — heating rods; 19 - boiler supply line

The electric boiler is designed quite simply: it contains a heat exchanger and a control and adjustment unit. There are complete models that are equipped with an expansion tank, filter and pump.

For heating private houses, low-power electric boilers are used: single-phase and three-phase.

Electric boiler cascade connection diagram

Single phase electric boiler

A boiler operating from a 220 V network is considered to be single-phase. Connecting it is not difficult, since all houses are equipped with the necessary voltage. The power of the device varies from 6 to 12 kW. It is advisable to use such a boiler for an area not exceeding 100 m2. Features of an electric boiler for home heating (220 V):

• works on the principle of a water heating device (boiler, kettle);
• a regular network (220V) is sufficient for operation;
• You do not need to obtain special permission to install it.

Electric boiler for use in a private home

Three-phase electric boiler

A three-phase boiler is more powerful than a single-phase one and is suitable for installation on an area of ​​more than 100 m2. So that the network can withstand the load during boiler operation, they are produced as three-phase, that is, they are connected to a 380 V network. Features of a three-phase boiler:

powerful

It is necessary to take into account the heated area. At 10 m? 1 kW + 10-20% required (for reserve); operates on three phases (380 V), it is necessary to increase the power supply in the house; it is necessary to obtain a special permit from the energy supply to increase power consumption and install a boiler; the rated current that must be in each of the three phases varies from 6.1 to 110 A

This indicator affects the choice of circuit breaker, wiring, and its cross-section (acceptable values ​​are shown in the table below). Correct selection of the necessary elements will eliminate the possibility of fire

the rated current that must be in each of the three phases varies from 6.1 to 110 A.

CONNECTING THE ELECTRIC BOILER CONTROL UNIT

We remove the insulation from the input power cable and proceed with the connection according to the following diagram:

IMPORTANT! Before connecting the electric boiler to electricity, be sure to turn off the power!

We connect the WORKING ZERO (blue-white wire) to any of the two terminals marked “X2”; they are connected by a jumper and there is no difference in which of them the wire is placed.

PROTECTIVE ZERO or GROUNDING (Yellow-green wire) must be clamped with a screw located to the right of the “X2” terminals; it is marked with a grounding sign.

To do this, I recommend stripping the insulation from the ground wire and rolling the copper wire into a ring, as shown in the image below:

Only then tighten this ring with a screw, thus obtaining a safe connection and reliable contact.

It remains to connect the phase wires to the terminals of the three-pole circuit breaker installed in the boiler.

The levers of this machine are independent; they are not united by a common jumper, which allows stepwise control of the power of the electric boiler.

It works as follows: each pole of the circuit breaker is connected to its own phase wire, which then goes to its own heating element.

The total power of the electric boiler is the sum of the powers of the heating elements located in the heat exchanger; if we turn off one of them with an automatic switch, the boiler’s performance drops by a third of the maximum.

The 12 kW ZOTA electric boiler we selected has three stages, each 4 kW respectively, the boiler can operate with a power of 4-8-12 kW, this is a very convenient way of adjustment.

When connecting an electric boiler to a three-phase electrical network, the order of phase rotation is not important, so you can connect the phase conductors to the boiler circuit breaker in any order. But I would advise sticking to the rule that the core colors always follow in alphabetical order:

1 – White conductor

2 – Brown conductor

3 – Black conductor

Now that electricity is supplied to the control unit, we connect it to the heating elements in the heat exchanger using the cable supplied.

I have already said that direct heating of water in this boiler model is carried out in a separate block, so now we will connect the electronic control unit with a block of heating elements - a heat exchanger.

Important features of the boiler operation

The GSM module can be built into all Zota models. It is not included in the standard equipment of the boiler, so it will have to be purchased separately. Installation and launch of the module is also ordered. The remote control can be installed in any room.

According to reviews from owners, Zota electric boilers are characterized by the following features of use:

1. Calculation of the boiler by area. Often, electricity is overused precisely because the device’s performance was calculated incorrectly. The power calculation must be 10-15% greater than the actual need. Excessive supply causes the boiler to overheat and often blow out plugs in the room.
2. Service maintenance. You cannot connect the GSM module yourself. To connect to the electrical network, you will also need to call a specialist. The service worker will also install the air temperature sensor. From time to time you will have to adjust the water sensor for hot water supply.

Remember that the pressure in the heating system should not exceed the parameters specified in the passport. Otherwise, equipment damage may occur.

Electrical installation in a single-phase network

As we have already said, you can connect the water heater to a single-phase network through a plug or a separately powered cable. There is no point in even stopping at the first option, because... Anyone can insert a plug into a socket.

As for the second option, first you need to carry out (if the required diameter of the cores is not indicated in the product passport), and then bring the conductor to the place. Then everything is simple - we connect the phase, neutral and grounding to the corresponding terminals in the unit (they are marked on them). For your attention, a schematic diagram of connecting an electric boiler with a thermostat to the heating system:
