How to choose and what to look for?

When choosing a model, you should pay attention to such characteristics as:

heat exchanger material - affects the duration of the device;
energy dependence - volatile boilers require uninterrupted power supply;
combustion chamber design - with an open chamber in the house, a chimney is required;
thermal power - determined by the quadrature of the room;
unit type - if there is a need for large quantities of hot water, it is worth giving preference to double-circuit options.

Types of Baxi gas boilers

The manufacturer has several classifications of units: by the type of combustion chamber, by the number of circuits, by placement and type of work.

By combustion chamber: There are devices with open and closed chambers. Boilers with closed chambers have a built-in chimney to maintain the flame and keep the air in the house. Open chamber boilers are used in houses with a chimney; in the presence of natural draft, the burning gas will be removed.
By accommodation: Wall and floor models stand out. Wall-mounted ones are more convenient to place in small rooms, floor-mounted options are large and demanding for installation.
By type of work: there are condensation and convection models. Condensing road options are rare, have high efficiency of more than 100%. In convection models, part of the heat is lost to the chimney.

How to choose the power of a gas boiler

To select the power of a gas boiler, you can use several methods.

The simplest is to calculate 1 kW of power per 10 sq.m. premises.

This simple approach works best for small, well-insulated buildings with double-glazed windows and low ceilings.

In private houses, one should take into account the height of the ceilings and use the formula MK \u003d Qt * Kzap, where MK is the boiler power, Qt is the heat loss of the building, Kzap is a safety factor of 15-20% of the calculated boiler capacity.
