Direct System – Retrofit – Frost & Frost Free

This particular direct system is used in both frost and frost free locations and 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 vacuum tube manifold, transferring solar energy into a storage vessel.


The solar retrofit conversion direct system, is specifically designed to convert an existing installed Kwikot or any other make or brand of high pressure electric water heater (400kPa or 600kPa working pressure) with a water storage capacity of 150lt and 200lt, into a solar system. The system works on the pump circulating method.
