Hi Phil, the heat exchanger idea sounds good. I did have a copper coil wound around the flue on one heater, it worked pretty well.
Fortunately our house is tiny and we only run the heater during the day in winter as the house gets too hot for sleeping at night for us if we keep it running.
The wetback can boil the water in the hot water tank also if we leave it running too long, there are only two of us and so we only have a 100 litre hot water tank.
If the wet back dies, I may change the system and see how your idea goes, I do have a couple of small pumps that would do the job, and still have the coil for the flue.
Cheers
Pete
