How Will a Heat Pump Perform?
|
The state-of-the-art heat pump technology can efficiently collect heat from the outside air down to the 45 to 50 degree range. For tropic and subtropic climates, this means that the pool can be maintained at 80 to 90 degrees under almost all conditions all year round. In northern climates, a Heat Pump will greatly extend the swimming season. For temperatures below 45 degrees, a Hot Gas option can be added which will allow the Heat Pump to continue to collect heat; however, efficiency drops as the temperature drops.
To determine the potential swimming season in your area, see the Solar Insolation Map and chart below:

Do I need a Pool Cover?
|
A Thermal Pool Cover is recommended for all heating systems. Heating a pool without a cover is like heating a house without a roof...the heat just goes right out the top. Without a pool cover, the cost of operating a Heat Pump or Gas Heater is doubled, and a Solar Heater's effectiveness is dramatically decreased. For convenience a roller may be added to ease placement and removal of the cover. If a pool cover is not being used, the size of the heater must be increased by 75% - 100%. Pool covers range in cost from $50 to $200 for residential pools; Pool blanket rollers offered in many styles and quality start at $185.
