1.0 DESIGN1.3 SYSTEM DETAILSPipe Sizing/MaterialsThe primary pipework connecting the boiler and the thermal store should be sizedto achieve a maximum of 8°C rise across the boiler or the maximum temperaturerise specified by the boiler manufacturer, whichever is smaller, but in any instance itshould not be less than 22mm copper tube.Note: There should be no valves in the pipework connecting the boiler to theBoilerMate 2000.The heating circuit operates on the normal primary boiler temperatures i.e. 82°Cflow and 71°C return. Therefore any traditional hot water radiators or convectorscan be used with this system and no special over-sizing of the heat emitters isnecessary.All the recommendations with regard to pipework systems in this manual aregenerally based on the use of BS/EN Standard copper pipework and fittings.However, we are happy that plastic pipework systems can be used in place ofcopper internally as long as the chosen system is recommended for use on domesticheating systems by the manufacturer and is installed fully in accordance withtheir recommendations. We always recommend the use of barrier pipe for thesesystems.Heating SystemIt is also essential that if an alternative pipeworkmaterial/system is chosen the manufacturerconfirms that the design criteria of the newsystem is at least equivalent to the use of BS/ENStandard copper pipework and fittings.Boiler SizeIt is only necessary to calculate the heatingrequirements in accordance with BS 5449.
