The BoilerMate A-ClassOV pdf Download
The BoilerMate A-ClassOV shown schematically above is designed to provide improved space heating and mains pressure hot water when coupled to any remotely sited condensing or non condensing boiler.
The principle of a BoilerMate A-Class is to separate the heat generator e.g. a boiler from heat emitters (radiators) by a thermal store, which evens out the fluctuating demands for heating and hot water.
An important feature of this concept is that hot water can be supplied directly from the mains at conventional flow rates without the need for temperature and pressure relief safety valves or expansion vessels. This is achieved by passing the mains water through a plate heat exchanger. The outlet temperature of the domestic hot water is maintained by a printed circuit board (A.C.B.), which controls the speed of the pump
circulating the primary water from the store through the plate heat exchanger.
To comply with the Benchmark Guidance Note for Water Treatment in heating and hot water systems the installer should check the hardness levels of the water supply and if necessary fit an in-line scale inhibitor/reducer to provide protection to the
whole of the domestic water system.
