Glow-worm 0020186153 DHW 14 Plate Heat Exchanger

Glow-worm 0020186153 DHW 14 Plate Heat Exchanger The Glow-worm 0020186153 DHW 14 Plate Heat Exchanger is a genuine boiler spare designed to restore reliable domestic hot water performance in selected compatible Glow-worm combi boilers. Also known as a DHW plate heat exchanger, secondary heat exchanger or 14 plate heat exchanger, this component transfers heat from the boiler’s primary heating circuit into the domestic hot water circuit. In a combi boiler, it helps provide instant hot water to taps and showers without the need for a separate hot water cylinder. A blocked, scaled, leaking or restricted plate heat exchanger can cause poor hot water performance, fluctuating hot water temperature, reduced flow temperature, boiler cycling, kettling noises or hot water running warm then cold. Replacing the plate heat exchanger can help restore efficient hot water delivery when correctly diagnosed by a qualified heating engineer.
