A condensing boiler is one of the most beneficial solutions for heating small apartments and preparing domestic hot water. On the one hand, they take up very little space, and on the other hand, they limit the emission of harmful substances. We can distinguish single-function boiler models and dual-function boilers . What are the advantages of both and which variant will work best in a small premises?

From the article you will learn:
- why gas heating is a good solution,
- what to consider when choosing a condensing boiler,
- what characterizes the MCR3 Evo 24/28 MI dual-function condensing gas boiler.
Why is gas heating a good solution?
Condensing boilers are compact heating devices that provide not only thermal comfort in rooms, but also hot utility water. Due to their small size, they are perfect for houses and apartments with limited space . What's more, gas heating is an ecological solution - compared to coal furnaces, for example, it generates less exhaust fumes, reducing the negative impact on the environment.
When choosing a condensing boiler for an apartment or house, it is worth paying attention to the differences between a single-function and a dual-function model . The former supports the operation of the central heating system, while the latter works independently, not only heating the rooms, but also preparing domestic hot water. It has a built-in tank, which is missing in single-function boilers.
Combination boilers are easy to install, relatively inexpensive and can be hung anywhere in the kitchen or bathroom. Modern models of this type are also characterized by a reduced risk of contamination, a minimized number of connections, intuitive operation and an attractive design. They are therefore an unrivaled solution for small apartments.

What should you consider when choosing a gas boiler for your apartment?

A gas heating system requires an efficient boiler that will provide as much heat as possible by burning the smallest amount of fuel. This is how condensing boilers work, using condensed steam to heat water . Models of this type are therefore much more efficient than traditional boilers with an open or closed combustion chamber.

The choice between a single- and double-function boiler should depend primarily on the size of the house for which the device will be intended. The single-function model does not have a built-in heat exchanger, so it requires the connection of a large capacity heater. The double-function variant, on the other hand, is equipped with an integrated domestic hot water tank, so the entire installation takes up much less space. Importantly, it will only work in small apartments, because it requires close proximity to hot water draw-off points (maximum 5 meters of pipe to the farthest point).
An important criterion for choosing a condensing boiler will also be its installation method. Devices available on the market are divided into hanging and standing . When considering which boiler to install in a small apartment, it is worth choosing a hanging model. It takes up much less space and is easier to integrate into the surroundings. Standing variants require more space, are heavier and more difficult to install.
When choosing a boiler for your home, you should of course take a closer look at the manufacturer and the quality of their devices. The best models will be made of durable materials and covered by multi-year guarantees.
