We swim yesterday for the first time this year. The water was 78 degrees and the pool enclosure mellowed out at 107. It was great. We don't have a pool heater. Just the enclosure and we also purchased a solar blanket that helped increase the water temperature a little. First swim April 5 2009, not bad for NC and no heater. Thanks for all your help with ordering and installation.

*Figures based on a 1,000 square foot, outdoor pool heated with an air to water heat pump with an average COP of 5.0 at $.085/kwh.

Table 2 estimates the annual savings of using a heat pump pool heater compared to using an electric resistance or gas pool heater.

Gas and Electric Pool Heaters*

Efficiency	Annual Cost	Cost w/ 5.0 COP	Heat Pump Savings
Gas Pool Heater
55%	$584	$200	$384
60%	535	$200	$335
65%	494	$200	$294
70%	$459	$200	$259

95%	$338	$200	$138
Electric Resistance
100%	$1000	$200	$800

Based on an electric resistance heated pool, which costs $1,000 per year at an electric cost of $.085/kwh, and using a natural gas cost 0f $.80/therm. A seasonal average COP of 5.0 was used to determine heat pump savings.
