Total Solar System Solution
Vaillant’s solar domestic hot water system has four major components – the solar collector, a hot water storage cylinder, a solar control and a pump unit.The sun’s energy heats solar fluid in the solar collector which is then pumped by the solar pump unit to a coil designed to heat water in a dedicated storage cylinder. A second coil in the cylinder is connected to a conventional heating source, such as a gas boiler, to provide additional heating when there is insufficient solar energy available. The boiler is also required to provide central heating. Managed by the solar control the system is able to automatically switch between solar and the auxiliary heat source to ensure there is always hot water on demand.
