LINING
The boiler is protected by a steel lining that first of all undergoes a
degreasing and phosphation process before being lacquered and
burnt at 220°C.
HEATING BODY
The boiler heat exchanger is constructed from mild steel with welded
joints. It is hydraulic tested under a pressure of 4.5 bar (maximum
working pressure = 3 bar).
HEATING ELEMENTS
Immersion heaters, constructed from stainless steel Incoloy 800 and
mounted in the top of the boiler, provide the power source for the
Boiler.
EQUIPMENT
The boiler is equipped with all the necessary components to allow
direct connection to a heating system without the need for a feed
and expansion cistern. These components include; primary 10 litre
expansion vessel (suitable for a system water content of up to 160
litres), pressure and temperature gauge, safety valve, circulating
pump, low water pressure switch, control and high limit thermostats,
on/off and power level switches.
CONNECTION
The boiler is suitable for connection to most heating and hot water
systems, with a maximum working pressure of 3 bar and a maximum
temperature of 87°C. It can also be used in multiple boiler installations
allowing greater outputs to be achieved.
The boiler, and connection glands for both the main power supply
and optional external controls are provided, suitable for single or
three phase electrical supply depending upon boiler output required.
An internal 3 amp MCB is provided to protect the internal control
circuit, from which optional controls can be connected e.G. Internal
or external timeclock.
CERTIFICATION
The boilers have been manufactured to comply with the following
standards BS EN60335-2-35: 1998, BS EN55014-2:1997 and BS
EN50081-1-1: 1992.
