How to choose a gas boiler?

Any home should have a heating system, because in our latitudes it is impossible to do without it, already starting from the fall and until the middle, or even the end of spring. The owners of apartments often simply have no choice - they use the services provided by state or private companies serving the entire house. Those who were lucky enough to build or buy their own house were a little more fortunate - they have the opportunity to create individual engineering systems. Gas boilers are widely used in the arrangement of individual heating systems. They have several advantages over electrical appliances. Let's talk about how to choose a gas boiler so that it can heat your room with maximum efficiency.

Power

The most important indicator that you need to pay attention to when studying technical specifications is power. The calculation here is simple: 1 kW of device power corresponds to 1 “square” of the room.

However, this calculation cannot be called accurate. For a more rigorous choice, you need to consider such factors:

• The number of doors, windows, as well as materials for their manufacture.
• The quality of the insulation of the room.
• Climatic conditions.
• Ceiling height.

Self-calculation of power in order to choose a boiler for the house is a rather complicated matter, therefore it is better to entrust it to a professional.

Important! The resulting figure should be increased by about 20%. Such a reserve will allow the boiler to function with greater power if necessary.

In addition, you must consider:

• Power supply stability. In case of frequent outages, in order to avoid breakdowns, you should choose the appropriate voltage regulator for gas boiler.
• The need for hot water.
• Location and dimensions of the room for the boiler room. In our separate review you can find out the mainroom requirements for installing a gas boiler.
• Free channel for the chimney.

How to choose a boiler? Model classification

Depending on the installation method, there are floor and wall models. Both options are suitable not only for space heating, but also for hot water.

Important! Wall models are more compact. They save space. As a rule, they are equipped with an expansion tank.

The removal of combustion products may be forced or natural. With forced removal of combustion products, a separate channel in the ventilation system is not needed. Such boilers have 2 operating modes - winter and summer. Working in the summer mode, the boiler only heats the water.

Important! The choice of a specific model depends on the stability of energy supply at home:

• Wall-mounted models are volatile and do not work when there is no power. Please note that in a separate post on our portal we examined the main selection criteria for a wall-mounted double-circuit boiler.
• Therefore, in the event of frequent power outages, floor models that are independent of power supply are more preferable. But in order to mount such a device, you need a separate room, and, quite spacious. Our separate review will help you choose the best floor boiler, in which we have prepared a specialrating of the best devices.

How to choose a gas boiler - a model for 1 or 2 circuits?

Distinguish single and double circuit equipment.The exact choice depends on whether you need to heat the water. If necessary, you should purchase a dual-circuit device.

There are double-circuit boilers of the following types:

• With integrated boiler.
• Flowing.

Compact flow models can be used if the need for heated water is small. For a large family, models with built-in boilers are suitable. The boiler capacity can be up to 200 l and even more. The volume of the tank is selected, depending on the specific needs of the family in hot water.

Important! The main disadvantage of a boiler with a boiler is that it is too massive and “eats” a lot of space.

Important! Are you planning to install the boiler in the house? What documentation is needed for this, how the installation and commissioning of the boiler are carried out, and find out a lot of other information in our article "Installation of gas heating boilers".

Advantages and disadvantages

For the right choice of a gas water heating device, you need to know about its pros and cons.

Floor

Here is a list of the benefits of a floor model:

• Simple, but solid and reliable automation.
• Non-volatility.
• High (about 90%) efficiency.

Minuses:

• Takes up a lot of space.
• The need for a separate channel for the chimney.
• There may be problems with heating the water.

Important! Sometimes it is advisable to use an additional heating element - electric or gas.

Wall mounted

Wall-mounted boilers do not take up much space, smaller in size. Their main minus is energy volatility, and hence the limited area of ​​use. Therefore, to purchase such a boiler for a country house is not the best option. Power outages outside the city, unfortunately, are common.

Depending on the ignition method, wall models are distinguished:

• Electric.
• Piezoelectric.

Important! Electric ignition boilers are driven by a special button. On models with piezoelectric ignition, the wick lights up continuously, even if the device is turned off.

Automation in gas boilers

Purpose of automated regulation systems:

• Regulation of the amount of gas supplied, depending on the outdoor temperature. This makes it possible to maintain a comfortable microclimate and save gas.
• Setting the heating power on time. For example, if nobody is at home during the daytime, then you can slightly reduce the air temperature. Or if the street is warm enough in the daytime and cooler at night, it is better to increase gas consumption at night.

Important! Carrying out repair work in a private house, take advantage of the innovations that we described in detail on our portal in the following articles:

• Do-it-yourself warm water baseboard;
• How to make a warm floor in a private house?

How to choose a heating gas boiler for the house - you now know. The gas heating equipment in a wide variety of options and price categories is presented on the market. The best (but also the most expensive) are products from European manufacturers. The choice of a specific model depends on the needs of the family. But in any case, it must be remembered that gas equipment is classified as dangerous, so only professionals should install it.
