<p class=section1 style='margin:0in;margin-bottom:.0001pt'>Everyone, I have a
building in Fairbanks Alaska that uses hot water heat. I built an energy model
for it and included a gas, natural draft, 80% efficient boiler to heat the hot
water. I then deleted the gas hot water boiler and substituted a steam meter. I
repeated this process for the gas DHW heater. When I ran the steam heat meter
energy model, I noticed that the Heating Energy Consumption was reduced by 38%
compared to the gas energy model. Nothing else seemed to change much, but the
reduction of heating energy bothers me. I realize that a steam to hot water
heat exchanger is more efficient than a boiler, but why does the amount of
heating energy required drop so much? Shouldn’t the amount of heat
required be the same for both models? I have attached the Energy
Consumption reports for both models. Thanks.<span style='font-size:10.0pt;
