BC Building Code-Section 9.33.5:”The required capacity of heating appliances located in a dwelling unit and serving only that dwelling unit, shall be determined in accordance with CSA F280.”
The only way to size the right appliance and distribution system is heat loss and gain calculation. We strive for accurate calculation using TECA software to insure that the installed equipment can sufficiently heat or cool the building. Homeowners should be aware that there is no way to calculate the size of the equipment based on the square footage only. Oversized equipment will short cycle and undersized equipment will not be able cool or heat your living space.
