Great little heater

For it’s size, it throws out great amount of heat. Great value.


Excellent product, Heats a room quickly and very easy to put together.

Well pleased

Easy ordering. Arrived on the day it was scheduled for. For a small heating appliance it gives a really good and controllable heat. Could not ask for more.

Excellent heater

It arrived promptly and is such an efficient heater. It is in quite a large shop and I have replaced an oil-filled radiator that just did not warm the space up until it was nearly time to close!! This heater is timed to switch on 45 mins before opening and the shop is lovely and warm.

Nice and warm

I bought this not knowing what to aspect. But i have to say im so happy with my purchase within minutes my lounge (which has opens stair case to rest of the house where the bedrooms are) is so cosy as well as the rest if the house. It does consume a bit of electric but I have storage heaters that are rubbish and we so were still feeling cold. With this heater I can see the difference in shirt period of time. Will order another one soon

Good little heater

Bought this as a temp replacement for a non working storage heater. I am so impressed with it. It is so effective I have had to turn the thermostat down and the timer is a real bonus. I have set it up so I get up to a warm room and it’s better than the original heater I had. I was surprised how small it is but it hasn’t affected his well it works. The only assembly needed was attaching the feet, plug in and it’s ready to go. I expect it’s not as economical as the old storage heater but as it’s only on a very low setting and timed I am not worried about the running cost.
