Description

There are two different kinds of heat exchanger that can be installed, they are the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and it allows the transfer of heat from the burner to the water within the system. The secondary heat exchanger is only present in combination boilers and allows the heat to be transferred from one closed system to another.

This part is present in 8 different boilers in the Worcester range including the Worcester CDI 25 , CDI 30 , GREENSTAR 25CDI COMBI, GREENSTAR 28I FSN NG, GREENSTAR 28I FSP LPG.
