Worcester 87161429020 DHW Plate Heat Exchanger
Rare part now obsolete from the manufacturer.
Manufactured by Alfa Laval.
Includes all necessary clips and seals.
This part fits several older Worcester boilers including:
- Worcester 280 FSN Combi
- Worcester 280 FSP Combi
Both NG and LPG.
There are two kinds of heat exchanger that can be within your boiler, the primary heat exchanger (also called a heat engine in Worcester’s terminology) and the secondary heat exchanger.
The primary is present in almost all boilers and allows the heat to be transferred from the burner to the water within the system.
The secondary heat exchanger is only found in combination boilers, and transfers heat from the primary circuit to the domestic hot water (DHW) circuit.
