HERE IS a night storage heating system that I installed in a 2 bedroom house using 3 x 900 Watt radiators.

The night storage heaters are supplied by a Spanish electrical manufacturer called Elnur. The models in the photos are the Gabbaron ADS 168/14 especially designed to be used together with a time-of-day rates tariff such as Iberdrola´s Day & Night Energy Plan. There are seven models in the ADS/14 range and they come in variety of widths up to 99 cm wide. The ADS 168/14 is the model generally used for an average size room, the dimensions are 54 cm wide, 72.5 cm high, and 16.5 cm deep. They are controlled simply by setting the charge and discharge controls on the top of the radiator.

Note how there are no cables exposed. The system is wired separate to everything else in the house because the radiators are controlled by a time switch. I use the existing conduit system installed in the property to wire the cables to an electrical point or junction box. This avoids any major building work and exposed cables, then the radiators are mounted at that point. Due to their weight they must be fixed to a wall. When a radiator is required where there isn’t an electric point, then fitting PVC trunking is generally the solution.

The bottom photo shows a new box next to the consumer unit fitted above a radiator used to house the switches and controls for the system. When space is not available in the consumer unit then a box is required.

This night storage central heating system included 3 x Gabbaron ADS168/14 radiators, a time switch, a contactor, on/off switch and all the associated wiring. The radiators are controlled by the time switch to switch on only during the off-peak times, when the electricity is half price.

During the off-peak period the radiators heat up and store sufficient heat to comfortably heat the property. They are individually controlled by a thermostat, plus they have an inbuilt sensor that regulates a constant temperature throughout the property 24/7.
