Electric strip heater?

[Panjandrum]

I'm looking for something that will fit along the bottom of a three-metre wall, looks very unobtrusive, never gets too hot to touch, yet provides a gentle heat rising up the wall. It would need to be no more than about 25mm square or diameter.

Does such a thing exist?

I've tried Googling but without success - so far.

Have you considered underfloor heating?

I don't think you are going to find a tubular heater that small in diamter, most tend to be atleast 50mm. They also tend to get pretty hot 90-100 degrees so probably a bit hot for your needs without a guard of some kind.

You can get skirting board heaters, quite thin but about 7" or so high.

Would you like to tell us why you need it?

do you have central heating?

A small pipe that is not very hot will give out very little heat (consider the hot pipe to your bath tap)

Thank you for your suggestions.
The purpose was to create a little bit of heat along the bottom of 10-foot-wide glass panel doors between kitchen and garden. This was in response to a suggestion that the doors, despite their thick double glazing, were cold.
I solved the problem by fitting a fused spur just beside a socket near the doors. Any time there is a grumble that the doors are making her feel cold I switch this on. Within minutes the problem goes away.

The fused spur is not connected to anything ... ...
The hard bit is remembering to turn this off at night
