What are floor-standing gas boilers?

Modern gas floor-standing boilers have an excellent design, compact size and operate almost silently, so they can be installed in any room in a private home that meets the requirements.
A gas floor-standing boiler is a stationary, single-circuit or double-circuit, most often atmospheric and energy-independent, central element of the heating system, responsible for the generation of thermal energy. In most cases, floor-standing models are not equipped with a circulation pump, air vent, safety valve and other heating system elements found in wall-mounted models.

Floor-standing models are more versatile, less dependent on weather conditions, gas and coolant quality, and according to operating practice and service call statistics, they are more reliable and problem-free. Like wall-mounted ones, they can operate on natural and liquefied (ballooned) gas; to switch to the latter, just change the burner. Prices for the most budget gas floor-standing boilers start from 12-13 thousand rubles.

Design and principle of operation

The device using the example of a floor-standing single-circuit Vaillant atmoVIT VK INT 164/1-5.
The design and principle of operation may differ slightly from model to model, but in most cases modern models operate on the same principle as classic old-style boilers, only the materials, manufacturing technologies and design efficiency have changed:

1. Natural gas is supplied from the gas main through the burner nozzles into the combustion chamber.
2. Using piezo ignition (by pressing a button in non-volatile boilers) or electric ignition (automatically in energy-dependent boilers), the pilot light is ignited, igniting the main burner.
3. Upon reaching the set coolant temperature, the gas supply stops and the gas burner goes out, the igniter continues to burn.
4. When the temperature drops, the gas supply is resumed and the igniter ignites the main burner again.
5. The walls of the combustion chamber are a heat exchanger within which the coolant circulates. The coolant distributes the accumulated thermal energy throughout the heating system, releasing heat through radiators, after which it is returned back to the boiler.
6. The oxygen needed to burn the gas is taken in through holes in the bottom of the boiler. Combustion products are discharged through the chimney through natural draft.

This is how classic non-volatile atmospheric (with an open combustion chamber and vertical chimney) models work. More expensive floor-standing gas boilers also come with a closed combustion chamber, they are also turbocharged. Air for gas combustion is forced into them using a turbine, which increases combustion efficiency. In this case, combustion products are discharged into them through a coaxial (side) chimney, as in most wall-mounted models, which greatly simplifies installation and room requirements. We will further analyze this selection criterion further.

Separately, it is worth noting parapet boilers, which buyers mistakenly often call chimneyless. They are neither wall-mounted nor floor-mounted and are equipped with a coaxial chimney, which is integral with the boiler. We have already written in the corresponding article why this option should not be considered.

Is it worth considering parapet gas boilers for heating a private home?

Advantages and disadvantages of gas boilers with a pump

The advantages of gas boilers with a pump include:

• metal parts of the system give off heat well;
• it is possible to change temperature conditions;
• Provides quick heating of heating radiators.

The only disadvantages of such a boiler include dependence on electricity and the need to bear costs for it. If the power goes out, the unit will not be able to work. Therefore, it is only suitable for use in regions where electricity is rarely cut off.

Gas, solid fuel, liquid fuel or electric

In total, depending on the fuel used, there are four main types of domestic boilers:

1. Gas (natural gas, liquefied gas). The most common and high-tech, they account for more than 60% of demand. In practice, heating with a gas boiler is one of the cheapest options, and at the same time the least labor-intensive: you don’t need to think about storing fuel, and many, even budget, boilers can operate autonomously, without the slightest human intervention, for days and even weeks. Modern gas models have an average efficiency of 88-94%, multifunctional automation, even the ability to connect a room thermostat, and the cost of good budget models from well-known manufacturers is in the range of 19-30 thousand rubles (Buderus, BAXI, Protherm, Lemax). The only difficulty is the long bureaucratic process of obtaining permission to install a gas boiler.

2. Solid fuel (firewood, coal and charcoal, peat, pellets). Solid fuel boilers are still an excellent choice in non-gasified areas of Russia, or if you have access to solid fuel at lower prices. The well-known and main disadvantage of solid fuel models is the need for constant participation in the combustion process, as well as the need to organize a place for storing fuel, its preparation and transportation. The design of modern models allows you to increase the burning time of one load to 4-6 hours if it is firewood and up to 10-15 hours if coal is used. However, the need for frequent refilling of fuel still remains a significant drawback. Fortunately, there are also long-burning models, up to 7 days, or pellet boilers with automatic feeding, but the cost of such boiler units starts from 60-90 thousand rubles.

3. Liquid fuel (waste oil, diesel, fuel oil, kerosene). Liquid fuel boilers are an excellent alternative to solid fuel boilers. Their advantages and disadvantages are as close as possible to gas models - and this is not surprising, because they differ only in burners. Diesel boilers and boiler units operating during exhaust are completely autonomous (you only need to replenish the tank in which the fuel is stored), sometimes have a higher efficiency, and when operating correctly, completely burn the fuel, emitting a minimum of harmful substances. If you try and find a source of fuel for a symbolic price (using equipment from agricultural enterprises, auto repair shops, bus or truck fleets), then operating costs may be lower than with gas heating. Despite not having such a large selection, there are clear leaders in the diesel boiler market - Navien and Kiturami, and we recommend that you pay attention to them when choosing.

4. Electrical . Electric boilers are ideal from the point of view of operating comfort, efficiency and functionality, but operating costs when using them are the highest. Heating a house with an area of ​​150 m2 may require from 10 to 14 thousand rubles per month, even taking into account reduced night rates. With an unlimited budget, this is an ideal option even for a house with an area of ​​150 m2, however, from an economic point of view, electric boilers are justified only when heating small private houses of up to 60-80 square meters.

Efficiency and selection criteria for energy-saving electric heating boilers

To summarize, if there is a gas main near your house, you should choose a gas boiler without hesitation. In the absence of a gas main, the best option is a solid fuel or liquid fuel boiler; the choice depends on the requirements for autonomy, the availability of a particular type of fuel, and personal preferences.

Which ones are more suitable?

When considering purchasing a gas boiler for heating a private home, which one is better to choose? Surely many people ask this question. So, when purchasing a boiler for a house of 150 m², it is important to consider several factors. Among them:

1. Total square footage and length of highways.
2. The degree of thermal insulation.
3. Diameter and material of walls.

Since units with an open burner do not have a chimney, it is necessary to provide for the effective removal of used gases. In closed chambers there is forced draft.

There are combined models with a special fan that increases air flow. Smoke from the use of blue fuel is discharged into the street through a small hole.

Such boilers do not provide for the organization of a chimney, however, they require careful care and cleaning from contaminants. If they are not maintained, the inlet will become clogged with leaves or other debris, causing the unit to stop functioning.

Each device has its own advantages and disadvantages. However, only options with natural draft are non-volatile units.

Heating automation

Before deciding which boiler to choose for heating a house of 150 square meters, you should also think about what degree of automation of this process you need.

Can you stay at home all the time and add new fuel every 4-6 hours? Then the most ordinary wood-burning boiler of 18-20 kW is quite suitable for you.

When using a buffer tank of 150-200 liters, a boiler of this power will be able to correctly heat the area you need.

If you require longer intervals between fuel fills, then you should consider more automated systems.

As an example, you can use a pellet or coal automated heat generator. Yes, their purchase will cost you 150-200 thousand rubles.

But at the same time, you can add fuel once every 2-3 days (the period depends on the volume of the boiler hopper).

If you use a large coal bunker or a big bag for pellets, you won’t be able to go near the boiler to add fuel for weeks.

How to choose a circulation pump?

To choose the right circulation pump, before visiting the store you should write down the basic data on which the choice will be based:

• area of ​​the heated room;
• characteristics and brand of the heating boiler;
• coolant temperature.

With this data, you can contact the seller of a specialized store, he will help you find a suitable pump.

It is better, of course, to choose a circulation device with a minimum noise level, but they have a power limitation.
The performance of such pumps is not enough to heat large areas. Note! When purchasing a pump with a wet rotor, keep in mind that it must have a special filter that prevents debris from entering the system.
There are also formulas that professionals use to calculate the optimal pump parameters. When choosing a circulation device, it is better to consult a specialist. To install it, you will need to call a service center employee.
