I can get water hot enough to do a radiant slab[120F], but how can I get my water to 180F for an air handler? What happens if I run the 120F water through the coil, take what I get for temp rise and add electric resisant as 2nd stage? Cost of operation will go up. How much? Any ideas would be appreciated.

    Derate your coil for a

    lower water temperature. We have heated comercial jobs just fine with 125° water, without supplemental heat. Some heat pumps will put out 140° water with out any additional modification. Paul
