Flue heat exchangers

A flue pipe heat exchanger transfers heat from the flue gases into the room. Both five-tube versions have a 130 mm connection and an integrated damper. The standard model is 750 mm tall and the XL is 890 mm tall. Both are 300 mm wide and 180 mm deep.

Compare the standard and XL heat exchangers. Check the available height, appliance compatibility, chimney draught and access for cleaning before choosing.
