Another bright idea for cleaner energy.

The Heatrae Sadia PremierPlus Solar is an environmentally friendly and efficient way of providing domestic hot water. Unlike some other 'twin coil' cylinders which simply use heating coils designed for traditional boiler heated cylinders, PremierPlus Solar cylinders have a purpose designed solar heating coil at the base of the cylinder, which ensures maximum heat input and efficiency from the solar energy.

PremierPlus is available in a choice of capacities from 170 to 300 litres, with a choice of direct (electric auxiliary heat input) or indirect (gas, oil or electric boiler auxiliary heat input) versions.
