Baxi Plate Heat Exchanger With Seals 7216606

The Baxi 7216606 is a plate heat exchanger for Baxi Main Eco Combi 28kW appliances, supplied complete with seals. It sits in the domestic hot water circuit and transfers heat from the boiler's primary water into the mains-fed hot water supply, so the appliance can deliver hot water on demand. The plate construction packs a large surface area into a compact body, which is why this component is heavily exposed to limescale and system debris.

• Domestic hot water runs hot then cold, or the temperature at the tap fluctuates
• Reduced hot water flow, or no hot water while the central heating still works
• Water weeping from the plate heat exchanger body or around its seal faces
• Scale or sludge blocking the plates, giving poor heat transfer and a boiler that struggles on a hot water draw-off

• Check the GC number on the appliance data badge against the compatibility list; the Main Eco Combi 28kW and the ErP 28 versions carry different GC numbers.
• Confirm part number 7216606 or the alternative number 1132088 before ordering.
• The exchanger is supplied with seals; inspect the seal faces and the mating surfaces on the appliance before refitting.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
