Familiarise yourself with the controls and instructions supplied with the Solar Cylinder and follow manufacturer’s instructions in the event of a cylinder fault. The pipework between the solar collector(s) and the solar cylinder can be very hot. These pipes should have been insulated by the installer. This is high temperature insulation.
