Types of boilers "Buderus"

To simplify the classification, the entire product line can be divided by installation methods and design

According to the installation method, all Buderus boilers are divided:

1. wall;
2. floor.

According to the design, separate features are distinguished:

• one or two contour;
• open or closed firebox;
• natural or forced draft;
• cast iron or steel heat exchanger;
• forced draft or atmospheric burner.

Condensing

Boilers of this type are innovative in the field of heating technology, they have a higher efficiency compared to conventional heaters.

This is achieved through the use of thermal energy, which previously simply “flyed into the pipe” with combustion products..

The principle of operation of these modifications is based on the use of heat released during combustion, part of which goes into the atmosphere, to heat the coolant supplied to the boiler furnace.

wall

These versions are most often used for autonomous heating of apartments, as well as small cottages.

Their popularity is due to their compact dimensions and the ability to install in a limited space..

single circuit

The most simple, compact and economical low-cost models.

The burner of such boilers can operate both in room heating mode and in economy mode, maintaining the specified minimum temperature of the coolant.

Dual circuit

The main advantage of such models is the possibility of independent heating of the coolant and water in the instantaneous water heater mode.

In the summer, when space heating is not required, the boiler can operate as a simple gas water heater..

floor standing

The power of such devices is greater than that of wall-mounted counterparts, usually it ranges from 50 to 100 kW.

These versions are used for heating residential buildings, as well as various premises and non-residential buildings..

Such boilers can have atmospheric or pressurized burners; they often use cast-iron heat exchangers than steel ones.

How to choose power?

For selection, you need to take into account a number of parameters: the area of ​​\u200b\u200bthe room, the height of the ceilings, the presence of a ventilation system, the heat-insulating ability of the walls.
