EDR / BTU's steam / hot water
When I measure up an existing radiator and calculate the EDR, I know you multiply by 240 to get the BTU's for steam. But for hot water I believe you multiply the EDR by 150 for 170 degree hot water - I seem to remember reading this in one of Dan's books - can anyone clarify?
