very good price

The heater is over all good and it was £30 cheaper then Argos so it was bargain . My conservatory don't have any heating at all and is walking fridge in the winter . so i wouldn't say that is not good heater as my conservatory is the with of my whole house so it doesn't heat that well but i understand is not easy to heat huge place with this size heater only . Thea reason i have given 4 star not five is a quite a bit noisy ... at one point i asked my husband to go and tuns the cooker extractor off, but it was the hear making this noise not the extractor lol .. over all is good heater for the price

Dimplex 403TSF perfect for when boiler breaks down

My boiler broke down during very cold snap. Bought 2 of these and within minutes the 3kW heater heated up my lounge and bedroom. The added benefit of the booster fan coupled with the built in thermostat setting enabled the room to quickly build up heat and then be maintained at a comfortable level. The only potential downside is that the cable is a bit short so you might need to get an extension cable depending on location of power socket.

Good heater

Arrived in good time. Heats the room quickly and maintains a balanced level of heat.

Highly effective and good value

Bought this plus the turbo- fan version (TSF), to keep the house warm until replacement of central heating Simple to fit the legs, turned on at 25% heat - and the warming effect was immediate. Two 16' x 12' rooms are toasty-warm. Silent operation and the timer is an asset, as it gives a warm bedroom before we get up. Highly recommended.

Great Heater

Next day delivery, very good Heater with thermostatic controls, does what it’s supposed too.

Dimplex 403TSF Convector Heater 3000W - White

Great heater, warms up in seconds. Finished in a satin white with plastic carry handles on either end, it's light and easily moveable about the house. Supplied with the reassuringly thick cable and moulded plug. With a small built in fan at one end, which is operated with a seperate switch. This blows warm air out from the front across the room. The body does get warm/hot to the touch, but you won't burn yourself. On / Off switch and a thermostat dial is all you need. We use it in the conservatory during the winter months, making this a comfortable, usable room. Service from AO as usual was spot on, with a phone call 20 minutes prior to delivery. 10/10 and thanks.
