does the heatslave 20/25 have a heat exchanger?

Hi John,

No, its an oil boiler, it consists of a 'water jacket' boiler, with some baffles inserted to pull heat from the flue gasses by slowing them down.

Unlike a gas boiler that has a replacable heat exchanger, in essence the boiler is the heat exchanger.

what problem are you having?
