My friend at works is trying to persuade his girlfriend to let them do a pool and an Enclosure . She doesn`t know what she and her family are Missing! I hope your holidays are festive and enjoyable.

*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 Pool Heater
55%	$584	$200	$384
60%	535	$200	$335
65%	494	$200	$294
