Heating
 

Hi Guys,
Wondering if you could help... I have just moved into a new Twigdens
home house and have a query regarding the heating system. I apologise
in advance as im not technically minded when it comes to this sort of
stuff.

We have thermostatic radiator valves in every room in the house bar the
study. The main heating thermostat is located in the hall. What I read
on various website that it is regulation that you should NOT have a TRV
in the same room as the heating thermostat where ours is (in the hall).
I have spoken to the builders and they say its ok because its on a
bypass. Is this correct or are they just making this up?

Why would you not have the TRV in the study and the radiator without
the TRV in the hall along with the main heating thermostat?

Thanks
Richard

They are bull****ting you with bits of misinformation.

It is possible to have one radiator without a TRV used as a bypass,
but normally if that's the case, it would be the bathroom radiator on
the argument that you would reasonably want heat in there in the
summer.

The radiator(s) in the location where the thermostat is located should
not have TRVs, although to save removal, you could just open it/them
full.

The study radiator should have a TRV.

It isn't a good idea, (Though not AFAIK against the law) they'd both
try and control the temp. in the room at the same time and "fight"
each other.

where ours is (in the hall).

There is a different issue which arises if all your thermo valves can
shut at the same time, and stop the flow of heating water altogether.
The boiler needs to have *some* water flowing through it so it's heat
exchanger and internal controls can work as intended. It's common to
provide a bypass to achieve this. sometimes it's integral to the
boiler, or a loop of pipework closeby, though it can be something like
a heated towel rail in the bathroom, or a radiator without a thermo
valve. If it is it's important that their valves are not disturbed.

It seems that the builders are trying to re-assure you about this
issue, whereas you are taking issue with the one above.

Well I'd prefer the other way around. I don't like to see the main
'stat where it gets influenced by opening the front door. OTOH you
don't want the heating of the whole house influenced by you switching
a PC and/or a telly on in a small study. It's my policy to put the
main thermostat where you spend most time and want the best control,
IE the living room. Though even at that if we put the decorative gas
fire on (For jolly Xmas atmosphere), or SWMBO starts ironing in there
the rest of the house goes cold. Maybe a different room with more
constant sundry heat input would be a better choice.

There are no end of other more complicated systems that are possible,
that measure the outside temperature, or contnually measure flow and
return temperatures USW.

ISTM the builders have left you with an attempt at a pretty standard
set-up but one which is less than optimal. JMHO, I hope you get some
others.

When I spoke to the builders they say its the same with every house
that has been built here and that its ok. Im not to worried about it
but I have paid a lot of money like everyone else so I think the job
should be done properly. The builders have been less than helpful in
regards to the snagging and putting things right. Now they have my
money they are not really interested in coming back. So far it has
taken them over 4 months to get them to start my snagging list which
they have only done since I complained to the NHBC which they wrote a
letter telling them to pull their finger out.

If they have broken regulations who should I contact to complain
seeings as Twidgens are not really interested and to be honest they
want bringing down a peg or two?

You could try contacting building control at your local authority.
They will have been involved in the building to check compliance with
Building Regulations. You can look up the relevant ones on
www.odpm.gov.uk and then part L1 which has to do with energy saving.

Having said that, you may not get huge interest from them as this is
not the most serious of transgressions.

As I understand it NHBC are generally only interested in major
structural type issues.

Snagging always seems to be an issue, but 4 months is unreasonable,
and this is the bigger issue. I would suggest contacting their head
office, identify the managing director and write to him. Send by
special delivery (about £3) and keep copies.

Not necessarily. It could have been overseen by the NHBC's Building
Control. If so, the OP is stuffed, as they are in the pockets of the
major housebuilders (although as I've never heard of Twigdens, there
may be a prayer).
