The g-save has two electronic timers which pulse at different pre-set times 24 hours a day, seven days a week. One timer is wired into the room thermostat wiring and the other is wired into the hot water cylinder thermostat wiring.
In a standard domestic system there is a time lag in the heating process. The time lag is caused because the thermostat demands heat from the boiler and the boiler responds, but it takes time for the heat to get around the system, and for the thermostat to register that the water or room is now hot enough. The thermostat then stops demanding heat; but the heat that is already in the system still has to work through. In effect, because of this time-lag, the water or room is overheated.
The g-save Economiser pulses the demand for heat so that the latent heat in the system that is still moving around is used to full effect, even when the boiler is not active.
