Our Expert's Opinion
“A domestic hot water heat exchanger that ensures effective, reliable heat transfer for hot water delivery.”Glow-Worm 20136540 Heat Exchanger DHW
Helps preserve system reliability and maintain warranty coverage compared with generic alternatives. The part’s construction supports efficient heat transfer and longevity under the high temperatures and pressures of normal boiler operation, helping maintain consistent hot water delivery and energy efficiency over time. Because this component operates continuously during hot water use, it’s often replaced during major service events or when symptoms like reduced water temperature, slower heat-up times, or boiler error codes relating to hot water performance appear. Professional installation by a qualified engineer is strongly recommended to ensure proper integration with the boiler’s control and safety systems.
