Remeha Heat Exchangers
There are two types of heat exchanger that can be fitted, the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and uses heat from the burner to raise the temperature of water within the system. The secondary heat exchanger only appears on combination boilers and allows the heat to be transferred between 2 closed systems.
