Controls ~ the range of controls available to regulate the heat
output and timing operations for a domestic hot water heating
system is considerable, ranging from thermostatic radiator control
valves to programmers and controllers.
Typical Example ~
Boiler † fitted with a thermostat to control the temperature of
the hot water leaving the boiler.
Heat Emitters or Radiators † fitted with thermostatically
controlled radiator valves to control flow of hot water to the
radiators to keep room at desired temperature.
Programmer/Controller † this is basically a time switch which can
usually be set for 24 hours, once daily or twice daily time periods
and will generally give separate programme control for the hot
water supply and central heating systems. The hot water cylinder
and room thermostatic switches control the pump and motorised
valve action.
