Flow heaters are used to heat liquids and can be used, among other things, as a complement to heat pumps and solar heating systems, or as extra safety in the event of a malfunction of the primary heat source. The flow heater is normally put into operation when the capacity of the primary heat source is not sufficient. It can also be used separately as the primary heat source. We can both manufacture flow heaters with standard components or according to individual customer specifications. A complete heating system can consist of a flow-through and a junction box with temperature control.
