I bought a coupla 1.3kW panel heaters for a quick heating solution for an annexe to my house which gets very cold. Buying from the website was really straightforward and gave me all the information I needed to make my choice. The heaters arrived within 48hrs -set them up and off to go. Delighted with the speed and level of heat output. Will probably have to keep them turned right down as they are much more effective than I expected - got one in an uninsulated loft room around 4m x 5m and the other in a downstairs room with three outside walls and draughty windows. I'm delighted as they were significantly cheaper than other suppliers despite the high spec (slimline with timers). Will definitely look to CNM for any future electrical purchases. Thoroughly recommended.
