Solar Power & Pool Heating – QIS Solarwise. Highly recommended 10/10. A very big thank you to Chris for arranging the plans and recommending best products to suit the installation of our solar power system and pool heater. Our requirement was for a solar power system that would supply the pool heater and also support additional home use. An excellent result from the installation team all done on time professional and very pleasant people to work with. Bruce & Chris. Chapel Hill.
