4.1 General description
This appliance is a purpose designed vented water
heater. The water heater has a stainless steel inner
vessel, which ensures an excellent standard of corrosion
resistance. The outer casing is a combination of resilient
thermoplastic mouldings and coated corrosion proofed
steel sheet. All products are insulated with CFC free
polyurethane foam to give good heat loss protection.
4.2 Operation principle
The appliance is used to heat and store hot water for
use in domestic & commercial applications.
The water is heated directly using a factory fitted
electric heating element and thermostatically controlled
by an adjustable thermostat.
This appliance is vented which means that the tank
where the water is heated is vented to atmosphere and
no pressure is built up in the appliance. The appliance
can be installed in only one way, cistern fed.
A cistern fed appliance is fed from a cistern tank and
vents back into this tank through a pipe at the top of the
appliance. Multiple vented tap outlets can be used with
this installation.
