After installing a pool heat exchanger to heat my pool with my EKO40, I have been struggling to see a difference in my pool temperature. I purchased a 250K btu heat exchanger to heat my 20,000 gal pool per the sizing chart. When the boiler is up to temperature, the pipes from the boiler are hot entering the heat exchanger and they are cool leaving, however I can not feel any heat in my water pumping into the pool. I have run the boiler 8-10 hrs a day and can not raise the temperature of my pool. Is there is anybody successfully heating their pool with a wood boiler? If so, what kind of results are you seeing & what is the key to your success?
