The QuanTec HR28C and its LPG equivalent the HR28CP both include integral ‘Passive Flue Gas Heat Recovery’
(PFGHR), which is the latest innovation for combination boilers.
Additional coils are added to the depth of the heat exchanger and the incoming cold water supply is re-routed such that it is preheated by the latent heat in the flue gases whenever a hot tap is turned on. This results in increased efficiencies in hot water mode of up to 26% over a standard combination boiler, resulting in typical savings in gas consumption of up to 25%. In addition CO emissions are considerably reduced and also pluming is virtually eliminated.
Johnson & Starley are the only manufacturers that have been able to achieve this without having to increase the cabinet size of the boiler. With no additional ‘add ons’ required and no increase in physical size, this makes replacement of existing boilers and new installations much easier with the QuanTec HR28C/CP with Passive Flue Gas Heat Recovery.
