Weather and Pool Temperatures

The Chart below shows an average of the Daily Highs for the first and last half of each month (2016 recorded temperatures). The scale is in Centigrade, with a conversion to Fahrenheit shown on each column. 

The Swimming Pool heating is provided by a 23 Kw capacity electrical Heat Pump, thermostatically set to 30° Centigrade (86° Fahrenheit).  This enables the pool to be up to 10° Centigrade (18° Fahrenheit) warmer than unheated pools in April, May & October.  This is far superior to Solar Panel heating, which often has only a marginal effect on temperatures in large pools.
