KWIKOT > SOLAR WATER HEATERS > DIRECT SYSTEM

Description
Designed to be installed in frost free locations where the ambient temperature never falls below 5º C and where the water quality is good (less than 600ppm Total Dissolved Solids/Minerals).

The potable water in the solar water heater circulates through one or more solar collector panels or manifold of an array of solar vacuum tubes installed outside on the roof, transferring solar energy into the storage tank of the solar water heater.

The solar water heater direct system can be installed as a Split System using pumped or thermo-syphon circulating methods, or as a Close Coupled System using a thermosphon circulation method.

The solar water heaters direct system, also work as a conventional electric water heater and are fitted with a Kwikot Solar Element and Kwikot Kwiktherm Thermostat. The element is designed to heat half the volume of water electrically, leaving the balance to be heated by solar energy by means of the solar collector panels or solar vacuum tubes.



Warranty
  • 5 Years on the inner cylinder from date of installation or alternatively from date of manufacture, if the installation date cannot be proven and subject to water conditions equivalent to main metropolitan supply authorities.
  • 2 Years on the Kwikot Safety Valve and Kwikot Drain Cock.
  • 1 Year on the electrical heating element, thermostat, flange assembly plate and gasket.
