Goals:
1) Heat our 436 gallon hot tub in Austin TX (usually mild winters)- wont be running in really cold temps (50+ degrees probably). Possibly heat pool (17k gallons) but not a requirement.
2) Consider automation
Have propane already plumbed but propane is very expensive and venting is problematic (will have to drill through a large structural concrete wall). So I was considering a heat pump.
Subpanel- 6 AWG wire run 50 feet protected with 60 amp 220 volt breakers on both ends.
Pool equipment mounted currently (all 220 volt- some old equipment has been pulled)
2.34 Amps 2 LED Sports Court lights = 2*1.17A=2.34 amps (30amp breaker previously used on older halide bulbs)
2.34 Amps 2 LED Sports Court lights = 2*1.17A=2.34 amps (30amp breaker previously used on older halide bulbs)
12 Amps Variable Pool Pump 12 amps@220V 1.5HP (20 amp breaker) (Pentair Superflow VS)
11.5 Amps Fixed Spa Pump 11.5@220V amps 2.6HP (20 amp breaker)
Total so far 28amps
Pool and spa are plumbed seperately but can be modified.

Questions:
- What size heat pump can I get? Should I look at MCA rating? Will it be adequate for spa heating (I understand heat pump will take a while).
- I wonder if its worth replumbing the pool to eliminate the dedicated spa pump (which has a bad motor which needs so be repaired anyway). This would save 11.5 amps in power requirement. Could be done in conjunction with automation.
- See attached pics. Yes its old (1990s). I’m in Austin and we are considering massive reno in 2 years so not trying to make is perfect.
