Types of gas boilers Vaillant
The model range of gas boilers, manufactured by Vaillant Group, can be divided into the following groups:
According to the number of circuits:
- Single-circuit VU . There is one heat exchanger, intended only for heating. To get the hot water it is necessary to connect a boiler.
- Two circuit VUW .. Provides the work of the heating system and hot water circuit.
By the exhaust of the products of combustion:
- Turbine type Turbo Tec.. Wall hung boilers with closed combustion chamber and forced combustion products discharge system (coaxial chimney).
- Atmospheric Atmo TEC. Combustion chamber is open, it is required to install them near the chimney on the basis of natural draught.
- Eco TEC condensing boilers. This is a special group of boilers, which uses the heat of the waste gas vapor, which improves efficiency and reduces fuel consumption.
By the method of installation:
- Floor standing boilers. They have an increased power (16 - 57 kW), a large weight due to the cast iron heat exchanger. They are suitable for heating the big house.
- Wall mounted boilers. They are compact, the weight is small, they easily fit to any interior. Do not require a separate room.

How to choose the capacity of the gas boiler
You can make a calculation using an online calculator program. It will be necessary to enter data on the area of the room, wall thickness, number of doors and windows, take into account thermal insulation and other information.
The program is free and allows you to choose the boiler with minimal error.
In order to calculate the output parameters of the gas heating boiler, it is necessary to use a simple formula: 1 kW = 10 sq.m..
This calculation is suitable for rooms with a ceiling height of 2.7 m and the average degree of insulation.
