This cold spell has caused me to think about replacing some of our
older single panel rads (non-finned) with new K2 double/double rads.
Any recommendation on best quality would be welcome.
Perhaps more importantly, any warnings about "bad-uns" would be
30Kw new condenser, off lots of the time. 6 bed house with just two
people now kids have gone,
most rads off but inadequate rads in large sitting room.
So, recommendations about rads, please.
Actually, I recommend reclaimed cast iron radiators. I got three
recently via eBay, had them shotblasted, painted them, fitted adaptors
and installed them, and I'm amazed at the amount of heat they chuck
out, compared to my old single-panelled rads - I still have some of
the latter in a couple of rooms, and there's no comparison. Cast iron
column rads have a large surface area. Unbelievably heavy though.
Radiators are very much a commodity - so find some that look ok, at a
reasonable price. I've used rads from Stelrad, Myson, Barlo, etc. as well as
unbranded ones from Wickes and Screwfix - and they've all been ok. For a
given size and construction (single with or without fins, double with single
or double fins) they all have pretty much the same heating capacity.
But don't forget to downrate them for the lower temperatures used by
condensing boilers - so you'll need much bigger rads than would be indicated
by believing the manufacturers' output figures.
Think about it - double panels with fins against single panel
older model boilers can be quickly destroyed by excessively low return
temperatures causing condensing. For a non condensing boiler which the
original post did not clarify ths is a very undesirable situation.
The amount of heat needed to keep the house warm is the same regardless
of the radiators. The amount of heat needed to take the radiator to a
set temperature will go up - but you don't need to take the rad. to a
temp., it's the house that matters!
... And that's a completely different issue to "extra thermal load".
Stelrad Elite, simple, good quality, no nonsense but I would use (& have
used) K+ instead of K2, they are double panels with a single convector
and I find them to be a more discrete solution, despite requiring more
wall area for the same output.
A bit like my ice cream preferences, a single nougat is an indulgence
but a double nougat it just rude.

I would steer clear of rads where the bleed valve is a small thin
brass screw inserted into a welded fixture located on the sides (the
type found at Wickes). I've known a few break off leaving the screwed
in part remaining in the rad. I'd go for ones where the bleed screw is
quite chunky and screwed into a removable fixing at the ends of the
I use Stelrad Compact - only because SWMBO likes them. I've noticed
when buying them on-line that you can find different prices all over
the place, but in the end PlumbCentre (Wolesey Ltd) turn up to deliver
from the local depot. The price differences are only a few pounds, but
hey if they are the same stock....
