Description

There are two kinds of heat exchanger that can be within your heating unit, the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and it allows the heat to be transferred from the burner to the water within the system. The secondary heat exchanger only appears on 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 GREENSTAR 12I SYSTEM, GREENSTAR 12I SYSTEM, GREENSTAR 24I SYSTEM, GREENSTAR 24I SYSTEM, GREENSTAR 24I FSN NG.
