Questions & Answers

Q:my home is 1600 sq feet what size furnace do i need
by|Oct 29, 2020
1 Answer
Answer This Question

A:  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 furnace. That being said. Oil is one of the most energy dense fuels. As a result it is difficult to burn number two oil in small amounts without producing excess unburned fuel; soot. Frequently I will do a heat loss on a home and come to 60 or 70 thousand BTU's. But then will end up using an oil furnace that is larger because there is not product smaller that I feel comfortable using. So often you end up sizing not to the actual heat load but to the fact that the fuel is oil. Chris 978 651 3301

    Q:is this upflow configuration
    by|Oct 3, 2020
    1 Answer
    Answer This Question

    A:  This furnace is a "low boy". So the heated air comes out the top like an upflow. However the return air also comes back through the top. If you open the PDF of the specification sheet found under the header "info and guides", on the Home Depot listing page, you will find an illustration of this.
