THERM 24 KDZN 5

The suspension condensation boiler THERM 24 KDZN 5 finalizes the successful series of boilers THERM 24. The boiler is determined for heating system warming and supply water warming in built-in tank. The water warming is made in the same way as in case of combination of boiler and external tank but with the difference that in this case all is covered under the boiler shell. Thus the connection between the boiler and the tank is not necessary.

With the use of boiler with integrated tank you get a complete year-long supply of heat and warm water in the building. In addition it can be used anywhere where a technical room is missing and the boiler is situated in the interior of a flat or a house.

The boiler can use for heating its thermal output 4,9 - 20,7 kW. For the supply water warming the maximum thermal output up to 24,0 kW is reserved. The unit suits for energetically less demanding buildings, but its increased output for supply water warming ensures the highest warm comfort.
