I have 3 heaters in the upstairs bedrooms and landing. Since the first cold weather of the '18-'19 winter they have proved to be much more effective than the previous electric radiators, and with thermostatic control they adjust to temperature changes so there is no need to worry about energy wastage. I also switched to the Fisher Energy suppliers too, who promise cheaper rates than my past supplier, and being aware of the Green needs of the planet was pleased to discover that they only use solar a wind sources to feed into the national grid. I look forward to seeing how the radiators perform midwinter.
