DESCRIPTION
The POTTERTON GOLD electric boiler is designed to heat re-circulated water used in wet central
heating systems. The water is heated when it is passed over electric immersion elements, which are
contained in a chamber. The temperature of the water is monitored and controlled by a modulation
technique switching on the immersion elements. The switching of the elements is carried out by
solid-state technology contained in the control section of the boiler. The operation of the boiler can
be controlled by standard programmers, room thermostats, etc. The pump should be connected to
the boiler control, which provides the run-on facility.
