Dimplex 403TSTI Freestanding or Wall-Mounted Convector Heater 3000W is rated 4.7 out of 5 by 9.
Rated 5 out of 5 by from Superwarm Heater This heater is amazing. It heated my cold draughty full length extension in no time. Screwfix were the only store that offered click & collect which was so convenient because i didn't have to wait in to sign for it. I ordered online on a Sunday and it was ready to collect on the Tuesday lunchtime. Really impressed with that. My only niggle with the heater is the lead is far too short so can restrict where you put the heater depending on where your plug sockets are situated. Wish the manufacturers would make them longer as i don't like extension leads trailing all over the floor. Otherwise an excellent heater.

Rated 5 out of 5 by from Great heater I needed a heater to replace one that packed up after 20 years. This one does the job. Not only a good power output, but the ability to go to a lower power if needed and a timer. Also being able to freestand, it has freed up wall space.

Rated 5 out of 5 by from Good heater, instant warmth Bought for conservatory, instant heat when first switched on, quickly warmed the 4mX4m room. Has been left on low as frost guard since, so far no issues, very happy cats only go outdoors now when they must

Rated 5 out of 5 by from Heater.... I fitted one of these in a store canteen a few months ago and it has been on almost continuously since. Store staff aren't the most robust.;-) Easily wall mounted or can be free standing with the supplied feet. All fixings are supplied but the wall brackets aren't the strongest and are easily bent by someone leaning on the heater once fitted. And they do. Needless to say it has, otherwise, worked flawlessly, coming on either on demand or at set times via the built in timer (this can easily be over ridden). It puts out a very reasonable amount of heat for its size and the thermostat means it can be used as a frost-guard device in somewhere like a conservatory. Recommended.

Rated 4 out of 5 by from Just Bought We needed a new heater on a wall in the utility room and are fed up with cheap ones that last 5 mins. We have paid a bit more for this but after 3 cheap ones in 3 years this will work out cheaper in the long run. So far so good.
