1.0 DESCRIPTION
The AMPTEC electric ow 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.
