Excellent product

I bought this heater for my conservatory which is very cold during the winter months. Within 5 minutes on a medium setting the conservatory was warm and cosy. The timer setting is brilliant as well. Excellent value for money.

Great heater.

It warms up very fast, silent and the timer is easy to use. Just what we needed!


Purchased this for our conservatory. Heats the conservatory in no time. Excellent value for money. Would definitely recommend.

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.


Easy to use and set up. Doesn't smell, effective heater.


So far the heater seems to be working fine, using to heat our conservatory the timer is very handy
