The Grant DuoWave Solar Cylinder collection was developed to meet the growing demand for systems that combine a renewable heat source with a standard oil, gas or electric boiler. They are particularly suitable for use with solar hot water systems like Grant Solar Thermal. When correctly installed, this arrangement can significantly reduce the dependence on traditional fossil fuels resulting in lower energy bills.
The cylinders have two coils for connection to primary heat sources. The solar heat supply should be connected to the bottom coil, which is designed to preheat, or heat the surrounding water, depending on the temperature of the incoming supply. The central heating boiler connections should then be made to the top coil. The boiler will only operate if the water in the cylinder has not reached the desired pre-set temperature and the boiler/cylinder controls are installed and commissioned correctly.
Featuring high efficiency corrugated heating coils, the Grant DuoWave range is developed to ensure a maximum transfer of the energy collected by renewable systems, and is perfect for technology such as solar thermal.
Indirect cylinders are heated from a conventional oil, gas or electric boiler, but provided with a second high performance coil which is linked with a renewable heat source, like solar thermal.
As a safety feature, indirect cylinders are supplied with a control/high limit thermal cut-out that operates at 90°C.
