Each SUMMERTM product features high quality aluminium, copper and stainless steel construction that offers years of trouble-free ownership and usage.

Each SUMMERTM water heating system by Solartech comes with two collector panels – each with 6 copper risers paired with 2m2 of collector fins with selective black coating for optimal heat conversion and performance-to-weight ratio.

Hot water is stored in a marine-grade stainless steel storage tank, which requires no sacrificial anodes to replace or rust and cracks to worry about. Marine grade stainless steel tanks offer superior performance over industry standard 304 steel tanks.

All SUMMERTM products byy Solartech are designed to perform under high-pressure. High pressure solar heaters do not create a loss of pressure when water passes through it, which means homes using such systems only require one water pressure pump. On the other hand, low-pressure systems require one water pump for the cold water and another for the hot water.


SUMMERTM products by Solartech rely on the thermosiphon principle to drive water through its system. Thermosiphon occurs when heated liquid rises and is replaced by cooler liquid in a closed circuit. As the cycle is repeated, the temperature of the liquid in the entire system is gradually raised.

Hence, because there are no pumps or motors, SUMMERTM products are cost-effective to own, use and maintain with its innovations in design of the solar stainless steel marine grade pressure hot water tanks and solar panels by using 100% rust proof, reliable, long-lasting durability product materials for its products to provide product life-spans of over twenty years.
