Heat loss, what size boiler do I need?
Hey everyone, I have another post running about contractor recommendations for an oil to gas conversion. I am just waiting on a couple more responses before I start making some calls.
I took some time today to install the SlantFin app on my iPad and went around the house measuring and entering everything into the heat loss calculator.
The result was just about 33,000. With this I started looking at boilers and most have a smallest size around 80,000/70,000 input/output. If my calculations was right those "small" boilers are about double of what I need.
What number relates to my heat loss number, the input or output? Do I need to factor in something for the indirect hot water heater? From what I read I will probably get a 40 gallon. Does that have a heat loss number I need to add to my 33,000 house number?
Sorry for all of the questions. Just trying to educate myself so I can have an intelligent conversation with the contractors.
