Thermecro solar spa heater

Heating your spa with solar power is an environmentally friendly way to save money on your energy bills. Solar pool heaters are also a great way to extend your spa season by keeping your water at a comfortable temperature over additional months of the year at no extra cost.

Thermecro converts a staggering 92% of solar radiation that strikes it into hot water for your swimming pool or spa. Thermecro is not reliant on outside temperature or direct sunlight so, unlike any other solar heaters on the market, it will work optimally in all weather conditions, temperatures and locations. Thermecro is an ideal solution for a secondary heating device.
