I'm about to fit UFCH in my new extension. Does anybody know who
makes/sells "heat spreader plates" - aluminium trays with a channel for
15mm pipe to sit in?
I've only found Polyplumb after hours of googling.

There are a number of online suppliers of UFCH components, so you don't
need to go to a specialist contractor if you know what you want. BES
http://www.bes.co.uk/ sell Polyplumb and Danfoss UFCH components,
including the Polyplumb heat spreader plates. Another to try is IPPEC
http://www.ippec.co.uk/erol/index.html used by a colleague in a barn
conversion.

As an aside I've come to the conclusion that UFCH is a bit like
kitchens and double glazing - it's seen as "exotic" and the market is
infested with companies who will do it all for you at an outragious
price. They mostly devote half of their websites to telling you how
good UFCH is but finding proper information is a nightmare. Rant over.

UFCH is essentially a very simple system.

UFH is not simple if you want it to work properly. An outside weather
compensator to anticipate temperature gains and losses is essential for good
comfort conditions, and economy. As is a Grundfoss Alpha auto variable
speed pump. Manifolds are essential to distribute the pipes to the zones,
which are usually one or two rooms. Electric wall stats can be used for
local control switching solenoid valves on the manifolds for each zone, or
use mechanical Danfoss variable flow stats, as in BES, and eliminate the
electric solenoids and stats.

Have the weather compensator set the temperature of a thermal store and use
an Alpha pump to pump this water to the manifolds.

Just connecting the flow and return from a boiler to the manifolds and
inserting a blending valve between taking the temperature down to 45-50C, is
the wrong way to do it.
