I understand that a boiler unit would be best, but it still doesn't answer my question.
How do the manufacturers of coal boilers calculate their coil size? There should be some kind of calculation? My radiant system consists of about 95 gallons of water. Most boilers don't exceed 180 degrees. So I know that my max output shouldn't be over 180 degrees.
How long of a coil would I need to heat 90 gallons of water effectively? And yes, I understand recovery rates too
I have a 1/4 hp motor on my current boiler. I've tapped into my lines already and I need to slow the flow down to achieve a better heat recovery rate.
/me is getting long winded.
Is there even a way to calculate the amount of coil? Maybe thats a better question?
