Which gas boiler is better to choose for an apartment in Ukraine

In the modern world, more and more users are switching to autonomous heating. Installing a gas boiler in your apartment.

Such a decision is quite justified and very convenient, since having your own single-circuit heating boiler in the apartment, you become completely independent from centralized heating, from a common boiler room.

The user himself decides when and at what power to turn on the heating or turn it off altogether, and accordingly, this is savings. In fact, this is very convenient, because you will not depend on a centralized boiler room and will be able to turn on the heating when you need it. And if you choose a double-circuit gas boiler , then independence in obtaining hot water supply will be ensured.

In this article, we will discuss in more detail how to choose a gas boiler for an apartment , what is the difference and what equipment is best.

Gas double-circuit boiler RODA - a universal solution

As a rule, in new houses during construction, autonomous heating is installed with a gas boiler, and in the bulk these are double-circuit boilers. They work for heating during the cold season and provide the user with hot water for domestic use all year round.

Also, there are projects when the heating is autonomous, but the hot water supply is centralized. And it is logical to install a single-circuit gas heating boiler, but this does not guarantee an uninterrupted supply of hot water all year round - repair work that can last more than one day, turning off the hot water supply with the end of the heating season.

Often an electric water heater (boiler) comes to the rescue, but the most common problem is the installation location of such equipment. At such moments, we recommend considering a double-circuit boiler, which at the right time can solve the problem of lack of hot water supply . And in general, why install several different devices, if you can solve everything by installing one, universal equipment.

Choosing a gas heating boiler - power

One of the main questions when choosing a gas boiler is " How much power do you need a gas boiler? " for a certain area of \u200b\u200bthe room. And the opinion "The more the better" in this matter is erroneous.

First: a higher power boiler will cost more.

Secondly: even if a more powerful boiler is set to minimum power, it will consume more gas fuel than a lower power boiler at the same settings.

Let's explain:

If you use a boiler of higher power for such indicators, you will still need to set it to the lowest power, and as you know, the lower the boiler power is set, the lower the efficiency .

If we compare the efficiency of the boiler when operating at maximum power, with the efficiency of the same boiler when operating at minimum power, the difference is significant - 94% and 80%, respectively.

Double-circuit gas boiler Roda with separate heat exchangers

Double-circuit gas boilers are divided into two types: with one bithermic heat exchanger and with two separate ones.

Let's analyze the fundamental difference between them:

• one bithermic heat exchanger is responsible for two circuits. That is, one heat exchanger provides the user with hot water and the same heat exchanger works for heating.
• two separate heat exchangers have a clear separation: one primary heat exchanger is responsible for heating, usually made of copper, secondary for hot water , made of stainless steel.

Among users, boilers with separate heat exchangers are always considered better. This is explained by the fact that if one heat exchanger breaks down, the other continues to work and in any case you get either heating or hot water for domestic use.

With a bithermic one, this will not work; in the event of a failure, the boiler stops working altogether. And at the price of a replacement, it is more expensive, as it goes 2 in 1.
