The introduction and almost universal acceptance of the use of the floating solar blanket has been the greatest advance we have seen in over 30 years of specialising in pool heating. The blanket allows the Sun's rays to penetrate deeply into the water. It also seals the surface preventing evaporation and cutting heat loss night and day - halving the running cost. Most heating systems will start to heat in the early morning unaware that the Sun will do all the work necessary and so they start to heat while the Sun is out - wasting energy competing with the Sun. | | Because the Thermalec operates only during the Economy 7 period, starting at about midnight, it's very sensitive control thermostat can detect exactly how well the water has been warmed by natural means, then makes sure the pool is exactly at the temperature you have set for your morning dip. After a warm day it may not have to heat at all, but after a dull day it may run for most of the night. During a typical summer it will operate for 3 or 4 hours on average, after the initial warm up period at the beginning of the season. |
