Heat Pump Applications
Swimming Pool & Spa Heat Pump Application (ISBN 0912524529) is as the name implies, is a book about the details of marketing, designing and installing heat pumps for swimming pools. In this 1989 book Mr. King does a good job of presenting the benefits of the electric swimming pool heat pump when compared to other types of pool heaters.
Heating System Sizing (Chapter 7) information is applicable to any pool/spa heating system. The conclusion that electric heat pumps are very cost effective is not surprising; however, I believe solar heating is equally or more cost effective in the Sunbelt when using the same criteria. Fuel (primarily natural gas) provide the quickest heat gain and can be more efficient when heating is provided only a few days a week or month. Heat pumps shine the most in areas where the pool is to be heated for an extended period of time during moderate temperatures without ample solar heat potential (e.g., out of the Sunbelt).
While I do not have a heat pump, there seems to be significant gains in both efficiency and popularity over the last decade. Here is a link to Pool Heat Pumps, which appears to be an informative and helpful on-line retailer.

Heat pumps are fantastic in application, however your average temperature and the manufacturers temperature for COP need to be compared.
For example if the manufacturers COP is calculated at 24 degrees celsius and your average winter temperature is 0 degrees celsius then you will not receive the benefits of owning the heat pump (if you want to use the pool all year round).
Most manufacturers have software packages that can predict the pool energy requirement and heat outcome based on location and this should be utilised to sort out the application in your pool.
I have sold heat pumps for over 20 years and am happy to answer questions on them and provide some calculations at www.poolindustrysecrets.com
