Filling the Domestic Hot Water & Heating System The Domestic Hot Water can be filled by opening one of the hot water taps in the house to allow the air in the boiler to escape and then the mains valve opened to allow water into the boiler. The 3Bar boiler pressure will be controlled by the pressure reduction valve.
System Control and Economy Measures Important It is very important that since the boiler stores heat to avoid using peak rate power, all pipes in the vicinity of the boiler and outside the heated areas in the house (i.e. under the floors and in the attic), should be insulated with good quality insulation, minimum thickness of 25mm to prevent standing heat loss.
The appliance has not been taken apart, modified or repaired by a person other than authorized by – Electric Central Heating Company (Heatwell)Ltd Evidence of the date of purchase and annual maintenance checks in the form of an invoice, receipt (or hire purchase documents) is required if service under guarantee is required.
