Return temperature maintenance of solid fuel boilers, wood-fired heating systems
and stove heating systems
The return temperature maintenance prevents the temperature in the boiler
from falling under the dew point, thus reducing the contamination of the boiler.
The return temperature maintenance is connected to a buffer tank. When the boiler circuit
has reached the set opening temperature (according to the specifications of the
boiler manufacturer), the performance of the pump can be used to charge the buffer tank.
