I've got a space below a breakfast bar where I quite fancy putting a trench
radiator. I'm not planning on adding forced convection with a fan, just a
passive radiator. (I think it might warm up the "knee space" nicely).

Anyhow, they look a bit pricey and I wondered if I could do anything myself
with a few (say 4 to 6) lengths of 15mm copper pipe. Clearly standard pipe
isn't too clever for radiating heat so I was wondering if there was any easy
DIY way of adding finning. Alternatively I suppose I could use heaps of
microbore but I've never played with that.

The trench would be about 2m long and I'd be happy to use any sort of
off-the-peg grill although I might DIY that too with some slats.

Any suggestions for finning and/or grill?

Yes. Look at car oil coolers and auxiliary radiators.

Ok theu are NORMALLY meant for blown applications, but even unblown you
get a lot of surface area in a small space.

If you have a local scrappy go looking for either small cars, or some
performance stuff that has these. Maany are meant for oil, but they are
still copper and can be soldered to conventional piping.

Hardly worth trying to make your own at £46/mtr.

Fabulous.

Stuff like that is so useful to know that it EXISTS never mind where to
get it.

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.

I think my reading has focussed mainly on France for various reasons -
but I think you are quite right.
