Thermaskirt ? Anyone tried it?

Just stumbled across "thermaskirt"
http://www.discreteheat.co.uk/downloads/technical/discreteheat.pdf

I am trying to get my head around the temp. differential between flow
and return as both pipes are thermally one and the same so heat will be
dumped to the return pipe at entry/exit point which seems a bit wrong
when trying to acheive a 20 degree f/r differential on a low temp 60/40
system.

I have dropped them a line but thought I would see if anyone here has
dabbled with this product.

Cheers
Pete

Its like the Mira stuff.. you don't want a big drop in temp, if you do you
need a lot more skirting as half of it will be cold(er) and half hot, the
same as radiators need to be bigger for a system with a condensing boiler.

^^^^
Apologies, forgot to say it's a download of their .pdf brochure as if
gave most info.

That was my initial thought and mailed the manufacturer the temp. the
technical answer came back as..

"If you work on around 1degC/m with the room at 21 at a flow rate of
56gm/sec you wont be far wrong."

I'll do a bit more delving and if I go with it, no doubt will post my
findings in due course.

Our boiler is weather compensated so flow temp is usually below 60
degres anyway, and our UFH in the living area only achieves a 10 degree
temp. drop at it's best so trying to acheive a 20 degree differencial is
more a case of the ultimate goal rather than a practical reallity.

Looks interesting. How does it compare cost wise with rads ignoring
installation cost?

On a par with UFH but with a fraction of the install costs or disruption.

I have been given a rough figure of £35/metre with an average bedroom
going in at around £400 or so.

Don't know if it's inc. or exc. VAT just waiting for an answer back.

I'll let you know.

We'd be alright on that score then as our bedrooms are downstairs and
pretty much under ground. Even in that really cold winter a couple of
years back we didn't have any heating in the downstairs bedrooms and
they never dropped to less than 10 degrees, so it's not got to achieve a
21 degree room temp in a typical "cold" house.

I think, judging by the good woman's reaction we will almost certainly
be giving Thermaskirt a go in 3 of the 4 bedrooms and the hallway.

Time will tell as to how well it performs.

We have UFH and wood floor in the living part of the house and it's
definatelybetter than the original set-up of 2 huge radiators and really
thick carpet that was here when we bought the house.#
There rads seemed to create a _lot_ of convection draughts.
I think it my just be you.
