Potterton Titanium Combi Main Heat Exchanger 5122147 – Refurbished

The main heat exchanger in a Potterton Titanium, Gold, or Promax Combi boiler transfers heat from the burner to the water system — and a deteriorating unit causes reduced efficiency, inconsistent hot water, and eventual boiler failure. The Potterton Titanium Combi Main Heat Exchanger (Part No. 5122147) is the direct replacement across a very wide range of compatible Potterton Combi and System boilers.

This is a professionally refurbished unit, quality-checked by experienced engineers, and supplied with a full 12-month warranty.
