For a little heater it will warm up faster than a more expensive one l would mark it 10 out of 10 if you're looking for a upgrade or need one this is the one to buy. You can start the heater with your telephone l have a Samsung 7 phone so you can have it going on the way home great to have a warm room

Great heater

Very effective heater, heats up our conservatory very quickly indeed. Easy to use and good variety of modes etc. Thought the Bluetooth would be a great feature but I’m finding I need to re link to it after it’s unplugged which I do when not in use therefore not really using this as I’m at the control panel anyway and easier to just operate on panel than through the app. The light which indicates it has mains power worked the first time I used it but has since not worked so I assume this has broken which isn’t great but doesn’t appear to be impacting how it operates.

lovely and warm

really easy to set up and use. soon as it turns on its set to 25 degrees. you cam move temp up and down. it knows when it's reached that desired temp snd switches off till it drops a degree or two, then it kicks back in. awesome that it van be go trolled via Bluetooth. 3 heat settings, eco, low, high. eco is great ss ut mo itors the actual room temp and cuts on and off to keep it at that temp. a really funky modern design, it looks great i my room.

Good but expensive

Only used for a few weeks but heats up 4 x 5 log cabin well enough. Thermostat is good feature. Far easier to operate with the app than to manually input timings. Hopefully Bluetooth will be reliable. Download Dimplex Remo app for this. Could do with a bit more weight around base area to give more stability. Very light. Seems to be rather expensive for what it is , but does the job. Purchased dimplex because of their reliability, so although expensive I would not have purchased another brand. Not many others on the market with the features of this. So overall would recommend.

Good heater with app

Good heater for my office. Powerful 3kw output and the app is a bonus, although it's a pain having to pair it almost every time.

Good heater......but.

The Heater itself is good but the Bluetooth app fails miserably. It just does not stay connected which is a shame considering the heater works so well. I would recommend this heater but not for the Bluetooth function. App needs working on big time.
