Heat Loss vs Heat Pump Ratings
Given an estimated heat loss rate, how should the listed capacities for heat pumps be used to select a unit that is capable of meeting my heating needs.
For instance, given a heat loss rate of 18,000 BTU/h for a house where the design temperature is 1 deg F, should I ensure the maximum capacity of a given heat pump at a temp close to my design temp, say -5 deg F, is approximately equal to the estimated heat loss? Or is that approach too conservative (given the small probability of those temps occurring) and likely to cause me to oversize the unit? And if it is too conservative, what are some reasonable alternatives.
