What it is
The Buderus 7101628 is a plate heat exchanger used in Buderus 500 series gas combi boilers. It sits in the domestic hot water circuit, where the primary heating water passes across a stack of corrugated plates and transfers heat to the mains water flowing through the alternate channels. Its job is to deliver hot water at the tap without storing it in a cylinder.
Signs this part needs replacing
- Domestic hot water runs hot then cold, or the temperature swings during a draw-off
- Hot water output is weaker than it should be at the tap, with the boiler still firing
- Scale or system debris has blocked the narrow channels between the plates
- Water weeping from the plate stack, the frame or the connection seals
- The boiler overheats or locks out when there is a hot water demand
Before you order
- Check the model and GC number on the appliance data badge against the compatibility list
- Confirm the number on the part being removed matches 7101628, T0000781440 or 78144
- Check whether new seals or gaskets are needed at the connections before refitting
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
