The VTP Series is a closed-circuit solar water heater that uses the highly efficient Evacuated Tube technology and perform equally well in areas of low and areas of high solar energy (such as the central highlands). These units can be installed on most roof/slabs, and is a reliable product designed to last a lifetime.
The evacuated tubes (with HEAT PIPE Technology) capture a high degree of solar irradiation by the selective coated inner surface contained within a glass vacuum, and transfers it to the heating heads inside the tank via copper rods due to high thermal conductivity. The heads in the tank then heat the water and is stored ready for your use - hot water free from the sun!
