Real radTherm® installs

What customers say.

Our installation of 5 Radiators took place 12th Sept 2025. The installation team lead by Tom Sullivan were punctual. The team were efficient, used floor coverings and removed all our existing storage heaters without leaving any mess behind them. The required electrical work was done quickly and efficiently. We have found the new radiators easy to operate via the app which is very user friendly. The radiators heat up to temperature very quickly and provide a comfortable environment throughout our apartment. Thanks to Mike and Tom for all their assistance and advice. We have no hesitation in recommending this company and their radiators.

In deciding to replace our existing electric radiators with a more modern look, we looked at number of prominent providers then following a meeting with Tom a Director of NWER we decided to order from them. On the day of installation Tom and his Team completed the install in four hours with a professional attitude. With the Phone App we can control our heating from anywhere at a desired temp. We are delighted with our new radiators and wouldn't hesitate in recommending North West Electrical Radiators representing a first class product by a professional Company.

Would highly recommend. Tom was very professional from initial contact to finish. Radiators are quality items, imported from Germany, very easy to operate with the wifi or in manual mode. You can also colour coordinate to suit your decor. The old adage comes to mind: you get what you pay for.
