A heating system 300 comprises a pipework circuit containing water which can be pumped around the circuit and combined heating means and pump 310 for heating water in the circuit. Heat emitting means 303 are mounted in or adjacent a space to be heated 301 and connected to the circuit for heated water to flow through the circuit from the heating means and pump 310. A control unit 311 monitors the air temperature within the space to be heated 301 with a temperature sensor 312 to maintain a substantially constant air temperature in the space to be heated 301 by adjusting the temperature of water flowing out from the heating means while maintaining continuous operation of the pump. The combined heating means and pump 310 may be a heat pump, or the heating means may be a heat pump, boiler or furnace. A temperature sensor (515, Fig. 5) may be used to determine the temperature of water flowing out of the heating means, and a valve (513, Fig. 5) may be used to adjust the outflow temperature. |
