A heating installation for a building comprises at least one source of hot water; a plurality of heat emitter means operable by passage of a heated fluid there through; and control means for the heating installation, provided with at least two temperature sensor means, wherein the or each source of hot water is operatively connected to heat exchanger means, the heat emitter means are operatively connected by at least one heat emitter circuit to said heat exchanger means, and said heat emitter means and heat emitter circuit contain an operating fluid having a freezing point below 0° C. This, together with the circuitry indicated in FIGS. 1 and 2 the components and control as specified and claimed enables room temperature to be held as low as +7° C. during unoccupied hours and with the external frost stats set as low as 2° C., a saving of energy is achieved. The heating installation can operate or be held off at temperatures above or below 0° C. This form of heating system can be applied to existing or new buildings |
