As is usually seen in Determine 4, components and hydraulic structure are mostly much like the heat-only variant, but With all the introduction of a plate heat exchanger to permit instantaneous era of DHW at Each and every dwelling, in the identical way as a combination boiler. So that you can make DHW at a handy temperature and stream charge, the main scorching h2o feed onto the plate heat exchanger must be inside the region of 75C. This may be at odds Along with the dwelling heating process running regime exactly where, within the occasion of underfloor heating as an example, the flow temperature necessary might be A great deal reduced.
This lends itself very well to assignments like apartments and social housing which might normally need multiple smaller boilers.
