What it is

The Andrews 7771812 is a heat exchanger kit covering the second and third heat exchanger positions on Andrews water heaters. It is listed within the Andrews hot water spares range for boiler-type appliances. The kit is used when the second or third heat exchanger requires replacement.

Signs this part needs replacing

  • Water leaking from around the heat exchanger body or connections
  • Reduced hot water output or slower recovery from the appliance
  • Scale or debris build-up restricting flow through the exchanger
  • Overheating or repeated lockouts linked to poor heat transfer
  • Visible corrosion or physical damage to the exchanger

Before you order

  • Confirm your appliance model and serial number against the manufacturer's parts list
  • Check whether the second or third heat exchanger is the position requiring replacement
  • Refer to the appliance's installation and service documentation for the correct exchanger arrangement
