STRONG HEART
The heart of the solar system is the storage tank (cylinder).
Unlike a conventional hot water cylinder, a solar cylinder needs to cope variable temperatures from cold tap water up to 95 ^oC.
In addition, a solar cylinder should have a larger capacity of approx 50 litre per person to optimise performance, and have superior insulation beyond NZS4692.2 requirements (MEPS).
