Manifold radiator systems can be considered much more efficient than standard systems as each room can run on their own separate thermostats, each room would be its own zone. Your Shopping Cart will be saved and you'll be given a link. With standard radiator systems, you are dependent upon not only a boiler and interlinking of pipes and radiators along the line, but you also run the risk of an inefficient and perhaps even a temperamental heating system. This can be avoided if you balance the system, but this can often be tricky depending on how well the flow and returns are piped. In the eventually of a leak, if you have chosen a manifold with isolation facility, it is easy to isolate just the circuit that is leaking, leaving the rest of the system free to continue functioning.
An underfloor heating manifold is an integral part of your new underfloor heating (UFH) set-up, but for those who have never had a UFH system before, it's something you may not have come across. An underfloor heating manifold is effectively two rows of taps that allow water to flow to separate pipe circuits that are installed in separate areas (zones) in the floor so that those areas can be balanced and individually controlled. The manifold is a good candidate for inclusion in a plant room if creating one in a self build home, for example, but this may depend on the layout and proximity of other technology also required in the room.
