Make that 3 who agree, and 1 who disagrees.

Then you didn't pay attention at all. This thread was made specifically for the benefit of those who do not weigh their coal any more often than once a heating season. Complements of someone who does. It grants them what may be the worlds simplest heat loss calculation method ever devised. Something that was formerly well beyond the means of the average Joe to accomplish on his own with any level of reliability, repeatability, confidence, and/or relevant meaning.samhill wrote:Somehow this thread takes all the comfort out of knowing my house will be warm & comfy when it's cold, snowing & a blowing. Little else matters, if I have to weigh coal before, after or during & calculate everything I may as well just use the propain & forgo the ease warmth & comfort of coal. I know it's summer but some need a hobby or more yard work ya just plain have way too much time on your hands.

The "HVAC guys" I would listen to are the ones who use the heat loss computations to check/ensure the adequacy of the installed radiation, and then size the boiler so that it is adequate to power that radiation. Failure to do so opens the door to a world of performance problems that are most evident in steam systems, but - as shown in various forum threads last winter - also can be troubling in hydronic systems.lsayre wrote:After the HVAC guys calculate a homes heat loss, how much padding factor do they (or better, should they) apply above that level in order to size a furnace or boiler?
