For the 50 AMP breaker, your old heat pump was probably close to maximum amp draw (with pump at full speed). So unless you want to rewire everything, you will probably need to stick with that size.
My 18 year old heat pump failed the end of last season and I need a new one? Looking for recommendations on brand. I have a 20 by 40 IG in New Jersey that I keep the solar cover on when not in use. Would like the water 80-84 degrees. Typically have pool up and running the end of April and close the first week in October. The current unit is 80,000 BTU/Hr but would like something larger if possible. I say if possible as the current breaker for the heat pump in 40amp and the Pentair continuously variable pump is on a 20amp breaker. The breaker in the house is 50amps and the wire is #6. Suggestions welcomed.
