b'KEY LESSONSWith a good heat loss estimate, it is possible to get a right-sized ASHP and to calculate many useful parameters that will help select an ASHP to meet the needs of a homeowner. Parameters like the thermal balance point (i.e., the outdoor temperature where back-up/supplemental is required), the annual heating load met by the ASHP, the financial perfor-mance and others, can be calculated using the Excel-based sizing tool in Natural Resources Canadas ASHP Sizing andSelection Toolkit.
