Using Water Heaters for Radiant Heat - University of Waterloo

A boiler's AFUE (annual fuel utilization efficiency) rating makes the assumption that heat lost through the jacket and spilled out the draft hood is dumped into the living space. If the boiler is in an unfinished basement or garage, however, this heat is actually lost. Water heater efficiency ratings, on the other hand, assume near-zero
