Using a Tankless Water Heater for Space Heat
WebBetter idea: flip things on their head. You need hot water to run a hydronic heating coil efficiently, far hotter than you'd ever set your water heater to (water heaters struggle to reach 180°F which is the standard temp a hydronic boiler is set to). However, your hydronic load probably pales in comparision to your domestic hot water load most of … Webstaying with a 20˚F (27˚C) Delta-T dictated by a rule of thumb. Consider another example, selection of an air heating coil, summarized in Table 2. A 20˚F (11˚C) delta-T on the water side is often used to size heating coils. High-performance systems require coil selection at a much higher delta-T, in the 80˚F (45˚C) range.
