If you are redecorating or refurbishing your home then this is the perfect time to install HeatingSave. Although some of our sensors are battery based wireless devices, the best option is always to run wires to the room sensors and heating devices; typically radiators. These are safe low voltage cable carrying 12 or 24 volts. Once the cable is in the wall it will last a lifetime. When our chairman installed HeatingSave in his home, he chose the wired devices where he could and only used wireless as a last resort.
