Mini heaters? Any good?

I’ve got a mini oil fired radiator, 650w, which costs about 22p per hour to run now. It’s got good reviews, and is excellent, you can move it easily and it keeps one room warm, if you’re cold when you first switch it on, you can move it so it’s closer to you. It’s also silent, I don’t like convection heating because it’s too noisy.

Not mini heaters but has anyone got a rechargeable gillet I m thinking if that my friend who is very well iff has a litter coat that she recharges has had it a few years and seems very happy with it
I wonder how you wash them ?

Ignore the huge number of reviews touting how wonderful they are and go to Trustpilot which is a genuine site.

The mini heaters are a cheap scam.

Hi. Do you mean the plug in mini ones (no cable)?
I’ve started looking at them. The reviews on Amazon aren’t great for any of them as far as I can see.
I’ve no clue about energy consumption full stop, obviously I need to educate myself!
