KWIKOT > SOLAR WATER HEATERS > CLOSED COUPLED DIRECT SYSTEM

Description
This direct system can be used in frost and frost-free locations where the water quality is good (less than 600ppm Total Dissolved Solids/Minerals).

The direct system, is where the water to be used in the household (hot water) circulates through the solar vacuum tubes manifold, transferring solar energy into the storage tank of the solar water heater.

This direct system is installed as a Close Coupled System (thermosyphon circulation), where the solar water heater is installed outside on the roof and above the solar vacuum tubes.

The solar water heater thermostat will automatically switch on when the incoming hot water from the manifold above the solar vacuum tubes, has not reached the set temperature setting on the thermostat. This will occur on cloudy days and at night when the water temperature drops in the solar water heater or when hot water is drawn off and cold water enters the solar water heater.



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 heating element, thermostat, flange assembly plate and gasket.
