Abstract: 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.

Abstract: A standby domestic power storage and supply for a domestic or residential premises, and establishments comprising: a battery or equivalent power storage device; (with or without a backup) and optionally single or three phase supply to suit the available space and specific standby demands an AC/DC converter for converting between a direct current and alternating mains current; and a system of renewable power systems integrated with the mains supply and the standby storage supply to afford mains feed in or alternatively top up of the electrical power storage device. An integrated wiring system suited for installing in new premises or retrofitting to accommodate power existing or new distribution boards. Especially the addition of a new essential power distribution board being fed from the mains or from the standby power storage unit when mains power fails. A new essential distribution board to provide essential power to dedicated and or critical power points.
