Under Floor Heating
A Wet type of under floor central heating works by pumping hot water through very small bore plastic pipework formed into a constant circuit that runs all the way around a ground floor room in the home. A boiler circulates the water. There are lots of ways that you can heat rooms but the best type if you are thinking of fitting out a big space, or maybe want to convert an entire home, is the Wet under floor heating system. If this is what you decide, then you will need to extend your central heating system. A Blackheath Plumber is familiar with Wet UFCH.Temperature Control:The best way to have control of the system heat is to fit something called a blending valve The boiler will feed the water at about 80 C but not to the under floor heating system. The blender valve monitors the water temperature in the UFCH (under floor central heating), and add small amounts of water if required to keep the temperature at 35-40C. There is a small under floor heating system, that does the same using a thermostatically controlled blending valve. Bigger systems use a manifold. This is a combination of a circulating pump, a blending valve and a bank of valves to manage the flow, isolating the heating in certain rooms as required. There are massive systems, where the efficiency is reduced because the boiler switching on and off every few minutes to fill the UFCH. Blackheath Plumbers supply and fit UFCH. The Buffer tank:The buffer is actually a thermal store, which a large volume of water kept at the correct system temperature fitted between the boiler and manifold, the boiler heats the thermal store, providing the heat for the manifold. This thermal store loses heat very slowly, heating the manifold for a long time without using the boiler. Great in a system that uses an air source heat pump, as the heat pump will run in the day heating the buffer tank, then in the evening use the hot water to supply the UFCH.
