I bought one of these little heaters during last Autumn. I live on a boat, and it can get very nippy at times. I've used it constantly throughout the Winter. It's still perfect. Safe to pre programme with a timer plug. I set it to start up about 20 minutes before I'm due home. The whole boat is warm and dry, all 40 ft of it. It stays on all night on a low thermostat setting. It has 2 heat settings, of which I only need the high setting occasionally, as the lower setting is good enough. Don't worry about the cold fan setting, i've never found one make that works well. Unless it's stuck up your trouser leg, you won't notice it at all. Quiet running, and so cheap to run. I don't like bricks and mortar, but I wouldn't be surprised to find that, if you put one downstairs and one upstairs in a 2 bedroomed house, you'd find a considerable saving in your electricity consumption. Run the hoover over the air intake at the back, to get rid of any fluff. I've just taken it out of the cupboard and dusted it off ready for another cold Winter session. Don't hesitate, go for this little heater. You won't go wrong.
