The tub is well insulated, with an insulated cover, so you need to account for that. My estimate on the hot tub cost is by comparing my kWh usage after the tub was installed to the prior year use.
Most small tubs are electric, like mine.
- danans 5y ago> I pay $0.13 per kWh in my town. So assuming $15/month, you are using 115kWh, which is 392kBTU of heating energy. It takes about 83kBTU to heat 200gal of water from 50F to 100F, which would be like 5 full heat ups from 50F. Of course there are the other convolved factors you mentioned (insulation).
