The greatest advance in pool heating - Thermalec + Economy 7 + Solar Cover - The lowest running cost for the family pool. Heating a pool by night is the perfect way of using economy 7 which is now much less than half price electricity - much nearer 1/3rd of the daytime rate and thermalec utilises this power in the most economic way possible.

The other benefit of E7 is to dramatically reduce the cost of the high output pump generally found in pools and spas, running your pump at night on E7 will also save you money. The thermalec heater packs such a punch that within the required 7 hours of filtration it will be able to heat the pool adequately.

The low cost reliable heating system for swimming pools and spas. Thermalec heaters are unique as in that they will operate with water coming from the filter at high velocity without it striking the heating elements directly. Instead the water is deflected by baffles, forcing it round the curved base of the heater. The patented spiral flow around the elements removes all the generated heat, minimising the risk of scale or sediment collecting within the heater.

Unlike convential pool heaters, the thermalec is guaranteed to holg its thermal efficiency for life, without regular cleaning or de-scaling. This means your running costs will not increase with time and maintenance cost will not increase with time and maintenance costs are drastically reduced. No need for expensive compulsary annual inspection required by fired boilers.

• Complete with all necessary controls to operate the heater, including contactors, pool temperature controller, manual reset excess temperature stat, and diagnostic lights.
• Due to the inherent safety of the patented Thermalec Spiral Flow design these heaters do not have to rely upon a flow switch or pressure switch – nor should one be fitted by the installer.
• 12 PHR Range - Single Phase
