1.0 DESIGN1.3 SYSTEM DETAILSHeating SystemRadiatorF & E CisternBM 2000Connection of Bathroom Radiator/Towel-Rail for Summer useIf a pumped circuit is required for the bathroomradiator/towel rail, the flow pipework can beteed anywhere into the primary flow betweenthe boiler and the BoilerMate. The returnpipework can be connected into the 15mmcopper blanked connection provided adjacentto the boiler pump. We recommend anyradiators/towel rails on this circuit are providedwith T.R.V.’s and that the total heat output ofthe radiators/towel rails is not more than 5%of the boiler output.The radiators will only get hot when theboiler is firing.BoilerIt is important that the flow rates through theseradiators is adjusted to the minimum requiredat the lockshield valves on the radiators. If thisis not done the performance of the BoilerMatewill be adversely affected.The height of the water level in the F & E cisternmust provide the minimum head required bythe boiler and must be at least 250mm higherthan the highest point of the system.D.V. : Drain valveF & E CisternIf heating of a single bathroom radiator ortowel rail is required in summer, then it canbe piped as a gravity circuit. The flow pipe tothe radiator can be teed into the safety openvent pipe and the return pipe from the radiatorcan be connected to the store drain connectionand the drain moved to the return pipe. Theradiator can be fitted with a T.R.V. if required aslong as this is suitable for gravity circulation i.e.low resistance type.D.V.BM 2000Page 15The height of the water level in the F & E cisternmust provide the minimum head required bythe boiler and must be at least 250mm higherthan the highest point of the system.BOILERMATE 2000
