Based on experience.
Instant water heaters require two things - low flow and high temperature differentials.
By incorporating a low temp buffer tank to show the instantaneous volume to raise the temperature of you can operate radiant reasonable effectively.
Without a buffer tank, or where high temperature emitters are employed they are a poor choice as a heating appliance.
IMHO..... Dan

    Are there any opinions or experiences with using a tankless water heater for radiant heat supply. Shop is 32'x40', 6" slab, 1" ins under, 2" perimeter, 1/2" pex on 12" centers. I am considering an Aquastar 240fx Heater with LP gas.
