    mastertemp heater cost of operation?

    just wondering how much does it cost to run the Mastertemp 400. Our Pool/spa just finished and we have been heating the spa a few times.

    Takes about 40min to heat the spa from 55 to 95 degrees.

    Heaters are usually speced in the amount of BTUs used so a 400,000 BTU heater will use about 4 therms in hour. For 40 min, that would be about 2.7 therms. The cost will depend on your NG rates.

    thanks.. my over baseline rate is # Therms x $0.96737 so about $3-4 an hr to heat the spa.. is not too bad.

    Want to feel even better? My 75.0 Amp 18 kW Tankless electric water heater requires about 8½ hours to heat my 750 gallon spa from 50°F to 100°F. At $0.25 per kWh, the heater reduces my net worth at the rate of $4.50 hour. But I must add 45¢ an hour for the circulating pump, SWG and controller -- all of which are in use while the spa is heating. If I'm sufficiently inebriated or just feeling reckless, I turn on the jet pump when we finally get in... at a cost of $0.60 hour. Total cost is something north of $50.00 - for a 30-60 minute soak.

    Ouch. I totally feel your pain. I suppose you dont have a Gas line to get a gas heater in your area?

    That's right. In 1978, 'all electric' still had a magical connotation -- clean energy from nuclear and those far off wind farms would supplant dirty coal and natural gas.
