SOLAR HEATING - Installation
System layout
A typical solar system for hot water with twin coil cylinder and conventional boiler.
The most common solar system layout uses a twin coil cylinder which is fed by both a boiler (or other heat source) and the solar panels. The solar system and the regular heating system do not come into direct contact with each other and the only shared part is the cylinder.
The solar system has its own pump, expansion vessel, pressure relief valve, air vent and controller.
