Heat Pump Vs Natural Gas Heater

[cleancloths]

Excellent links!!!! Thanks for posting.

Please note that the methodology is good, but the energy numbers are out of date. They base the data on electricity at 8.5 cents per kwh and gas at $0.50 per therm. Thus, the actual economics will vary by a function of what you actually pay for energy.

In my neck of the woods gas is going for about 85 cents a therm in the summer (it goes to around $1.80 in the winter, but pool heating is in the summer.)

While electricity for those that pay for it is on average about 15 cents/kwh during the summer. When I installed my pool I went to time-of-day electric pricing which is now about 18 cents/kwh during the day and 8 cents per kwh at night. But since then I installed a 10kw solar pv array on my home which generates over 12,000 kwh per year. So, my electricity to heat the pool with the heat pump is very cheap.
