Home size 832 square feet , thermostat set on 64 and the low is 23. Unless your house doesn't have enough insulation and has lots of air leaks the heat pump should be able to keep up under those conditions. Make sure the filter and coils are clean.
As a comparison my 1955 built home is 1000 square feet and needs 6,000 BTU to maintain 72 when it's in the low 20's outside. The heat pump produces enough heat to maintain 72 down to 9 degrees. Gas back up is cheaper so we don't run it that hard but just wanted to see where the break off was.
