28/2/2018 · I figured I'd have a go at calculating the standby heat loss of my boiler. For a back of the envelope calculation -- quite reasonable, and quite correct. Just round it off to around 20,000 BTU/hour. As @EBEBRATT-Ed noted, some of that is wandering off up the stack -- but a good deal of it (I'm not quite sure where Mr. Cates gets his 9% figure, but that's of no importance) is "lost" to the Get Price
