Radiator Delta Ratings Explained | Only Radiators
Converting Between Delta T50, T60, & T70. The conversion are as follows: If a radiator has a heat output of 5000 BTU at ΔT=60, to find the heat output at ΔT=50, you simply multiply the BTU by 0.789. So your equation would look like this: BTU (ΔT=50) = BTU (ΔT=60) * 0.789 = 3945 BTU. If you have a radiators with a heat output of 5000 BTU at ...
