Great alternative to gas central heating. More controllable as it has individual thermostats for each room which allow you to choose a different temperature for each room if you so desire. Each individual heater can be turned on or off at any time of the day or night so it is totally controllable unlike the old fashioned night storage heaters. Unlike gas there is no heat loss through the pipes carry hot water to the radiators as there are no pipes running all over your house, just simple wiring to the nearest wall socket. I currently have five in my house and find they do exactly what I need them to do and would recommend them to anyone.
