The balance point of a heat pump is the lowest temperature at
which the refrigeration system can heat the building without
any supplemental resistance heat.
The balance point is dependent upon -

2. The building heat loss at the outdoor design temperature,
and
3. The heating capacity of the system at the outdoor design
temperature.
Refer to Form 515.41-AD1 to determine balance point.
