We had a 2 panel standard Solarhart on the coast for 18 yrs ,no problems. Here in the bush we have had the heat exchanger Solarhart for 12 yrs and only turn on the booster if more than 2 days of rain.
We have a wood heater in the room under it , does anyone have experience with putting water coils around the flue and plumbing into the Solarhart pipes?
