Good Effective Heater

The product arrived with a broken piece of plastic that covers the end corner of the unit. That said there appears to be no issue with the operation of the unit.

Pros: Ease to use, Looks good Cons: Noisy

Get one !

I have ordered a total of three convector heaters over last month ... I've tested them all at hone and this one is by far the superior one . The heat it creates it fantastic . It heats the room up quickly and it's quiet too . The timer is great for cost saving and easy to override if you need to . It's sturdy and looks expensive . If I had to mark it down for anything .. then I'd say the removable pieces on the base could have better and stronger fittings . But if you need a heater for when it's really cold ... get one !

Pros: Ease to use, Good build quality, Looks good, Quiet, Value for money

Great heater

Good quality product that heats up quickly. The timer is easy to set and ensures the room is warm when you want it to be. Minimal self assembly required to put the feet on or to hang it on the wall.

Pros: Ease to use, Good build quality Cons: None


Bought it to warm the converted attic room when required for guitar practice and it does the job,however it is not as economic as advertised. Easy to mount on the wall. Not attempted the timer,looks complicated. Great service,delivered in less than 24 hours.

Pros: Looks good, Quiet Cons: Expensive


Good for those cold days when you need an extra heater. Unfortunately if you use It at full potential of 3Kw the fuse in the plug will overheat and can become dangerous, so only approx. 2Kw of 3Kw can be truly used.

Pros: Ease to use, Quiet Cons: Expensive
