Hate to make you feel even worse but how about 9-10 months a year (with the heatpump going for about 4-5 of them). Oh, the hottub gets used in the other 2-3 months! This is why I no longer live in New Jersey I hope to add solar in the next few years once my piggy bank recovers from the pool builder from h*ll that I still am fixing so don't begrudge me this one!
