Glowworm Flexicom Main Heat Exchanger 0020054164 – Refurbished

The main heat exchanger in a Glowworm Flexicom boiler transfers heat from the burner to the water system — and a worn or leaking unit causes inconsistent heating, reduced efficiency, and in some cases complete boiler shutdown. The Glowworm Flexicom Main Heat Exchanger (Part No. 0020054164) is the direct replacement that restores efficient heat transfer and reliable boiler operation across the compatible Flexicom range.

This is a professionally refurbished unit, made from durable materials for long-lasting performance, and supplied with a full 12-month warranty. Designed as a direct replacement, it installs without modification.
