There is no universal consistent relationship between square footage of floor space and how much heating capacity you need to install. When it is suggested there is, the formulas typically end up oversizing the product in the vast majority of cases which greatly decreases the efficiency and longevity of the equipment. As I am sure you can envision the same structure if located in Alaska is going to need a lot more capacity than it would if located in Florida. The proper way to size heating is to do a heat loss calculation. There are many free programs on line that will do this for you. Basically you enter room sizes, window sizes, construction type, geographic location, etc. and the program will calculate how much heat the structure will lose on the coldest hour of the coldest day of the typical year. Selecting the capacity that is matched to the actual load you will get the longest and most efficient run times. Sometimes if the current system is working properly I will base my choice on the information on the rating plate of the current boiler or I will look at the currently installed distribution capacity and work backwards. For example my home has 100’ of copper fin tube baseboard. I know that the brand and style that I have puts out 580 BTU’s per foot. So when buying a new boiler I knew to purchase one that had an output of 58,000 (100 x 580 = 58000) in order to take full advantage of my installed distribution capacity. If you would like to talk about you specific home please feel free to give me a call. Chris 978 651 3301
Yes it can be converted to gas and comes with the requisite conversion items.
