Underfloor heating manufacturers recommend the use of zones. Are these necessary ?
Generally, zones in a house or building, as discussed above, cover parts or sections of a building. They are quite different from floor heating zones for underfloor heating. Underfloor heating zones relate to floor areas in which heating pipes are laid to distribute heat and, as such, may be compared with radiators in a conventional central heating system. A valve may be used in conjunction with a thermostat in such systems to control an underfloor heating zone and to perform a similar task to that of a Thermostatic Radiator Valve – see TRVs below. However, several underfloor heating zones, normally grouped and controlled by a manifold, may be treated as a single zone and controlled by a DCD Controller in the way that is described above.
