Schools? Make that all local authority buildings, also the programmer
turns on in September and doesn't turn off until April.

No acount taken for expansion. Serious design fault I hope that the
architects will be paying for *all* remedial work.

Why don't they just turn the boiler down?

Or adjust the zone thermostats, but as they "forgot" expansion gaps maybe
they "forgot" theromostats as well.

The UFH should be on a variable temperature circuit(s) with its own
temperature control valve; the boilers would probably also be
supplying higher temperature water to air handlers and water
calorifiers.

It could be a simple control glitch or possibly they can't turn the
UFH temperature down and maintain the room temperatures. The latter
would suggest an UFH design balls up. That might involve all the
floors being .hacked out.

It would be interesting to know who the Mech Services Consultants were, as
in the past. :-)

It doesn't mean it was down to them, there are lots of parties
involved any one of whom can wreck a good scheme.
The tiles may have cracked just because the floor was being run above
the maximum design temperature. One project I heard of suffered a
runaway UFH system over a week-end and most tiles had cracked by
Monday. Marble tiles. Ouch. There but for great good luck to date, go
I.

They could use the programmer we had at RAF Catterick in North
Yorkshire. The anaemic heating system turned on on the 14th of
October (and usually immediately broke) and went off again on the 1st
of March.

Same with all those NHS PFI projects - they never use a long enough
spoon and the floors start to overheat from sheer proximity

Even so the system should have had both a normal control of the UFH
temperature and an overheat cutout. Sounds like both were FUBAR.

Sounds like my office :-(

We have heating on at the moment - no control appart from opening the
window which isn't much fun with the winds recently :-(

I used to be in the office next door, and know what you mean! There is a
little lever but it doesn't do a lot...

I'm still in the same building but must be at the end of the line as
they've given me a supplementary heater...

We have had the temperature above 28 already this year. Today only about 24.

I was wondering of the underfloor pipes were uninsulated. Obviously they
need to be where you want the heat delivered. But to transport it from
one end of a corridor to the other, you probably need the main flow to
be insulated.

Know what you mean about the schools. But apparently it's wood fired,
and not easy to regulate.

And apparently this terribly hot floor gets up to 40c. Sounds about
right to be nice and comfy in your bare feet - just above blood
temperature. What's the problem?

Happened to someone I know. They just have ordinary radiators, not
underfloor heating, but controls went wrong and cooked the house.
This wrecked a reasonably newly laid solid maple floor in a very
large room, which expanded and then left gaping cracks everywhere.
Floor had to be taken up and put down again, at a cost of thousands.

The management of public institutions, following the lead of 30 years'
worth of successive governments, are completely in thrall to the
corporate sector. Long spoons? They just can't get close enough!
