Dimplex 403TSF Convector Heater Delivery arrangements - fine. Product generally OK, but found a spare screw in the box - not clear where this came from. |Running the heater with the fan on it is sometimes noisy as if there's a component not tightened down properly. Otherwise the heater works OK - no surprises as yet.

Pros: Ease to use, Value for money Cons: Noisy

Good for a smaller room

Delivery and price is good. The product does what it says but our room is 28 foot long be 12 foot wide and always cold. This heater it isn't sufficient to keep it warm but probably on a small room with better insulation it would be perfectly adequate. I thought with the additional fan it would be ok and that was the reason for purchase.

Pros: Quiet, Ease to use, Value for money

Heats space quickly

Very pleased with this heater. I have it in a small flat and it heats several small rooms quickly. Also impressed with the fast free delivery. Would recommend.

Pros: Quiet, Ease to use, Value for money, Looks good Cons: None

Quite noisy

It's an OK product, I guess one gets what one pays for. This unit has a hit or miss thermostat which seems to click in and out far too frequently and cuts in for a few seconds, even though the heater is used in a conservatory which isn't too energy efficient. The turbo boost fan is noisy. It's a shame that another cheaper heater which didn't have the turbo boost did have a digital display so that the actual temperature could be set, rather than turning a dial until you hear a click!! Overall, the heater does give out a good heat (it's 3KW, so will be quite heavy on energy usage. The build quality is OK and it is wall mountable.

Pros: Value for money, Looks good Cons: setting thermostat - guesswork, Noisy
