SolarTherm solar water heating systems are designed and manufactured to optimise the heat absorption and efficient heat transfer from solar collector to the water running in the copper riser tubes of the panel. Heated water is transferred to the insulated hot water storage tank by thermo syphon effect. The heated water is stored in storage tank for usage.This is a continuous cycle taking place as long a the sunlight is available. Since 1982, SolarTherm has established themselves as a 100% solar power solutions provider. As the market Leader in the industry, SolarThem lives to the promise of continued quality and reliable service.

  • SolarTherm Hot Water Storage Tanks are constructed from 304L food Grade Stainless Steel with the right thickness, a corrosion-free material, which is safe and durable, requires minimum maintenance.
  • The storage tanks are designed to minimise mixing of hot and cold water during usage and are insulated with polyurethane foam ensuring superior insulation and minimising overnight heat loss. SolarTherm provides glass lined tanks for areas where quality of water is an issue.
  • SolarTherm solar collectors are manufactured to optimise efficiency by using selective heat absorbant surfaces and copper riser tubes embedded to the collector surfaces by using ultrasonic fusion bonding technology.This is to increase the efficiency of the heat transfer.
