I moved into a newly built house last October with Underfloor heating.
The problem is it is using 1000 litres of oil on average every 6 weeks.
The house is approx 2000 sq ft. I have had the boiler checked out
(commissioned and serviced) but no joy. I have the temp at the boiler
set to the lowest setting (dial reads 0 to 5 not temp so don't know
exactly what temp this is). Each room has own REHAU stat and these are
set around 20 - 22 degrees. Only prob is the control doesn't seem to be
great - some rooms warm some colder. I was thinking of changing the
room stats to see if I could get better control and better efficiency.
I have also had a UFH installer check out the system. He says it should
be ok. Any ideas out there??

do you know what the sub underfloor heating insulation consists of ?

if the house is well insulated and everything else is within spec, the last
'known unknown' would be the insulation under the heating system. if
that was installed incorrectly or it's insubstantial you could be heating
mother earth instead of our house ?

Doesn't apply to everyone, but one or two candidates (okay, one

1000 litres of oil every 6 weeks does seem highly excessive.

Don't want to alarm you but is it possible you might have an oil leak some
where and an undetected oil slick building up on the scale of the Exxon
Valdez?

Not particularly, in a big house in a cold late winter.

I'd say you have less than ideal insulation somwehere.

Or a wife who opens the windows when shee feels too hot, rather than
turning down the heating..;-)

Its unusual in a new house though, 2000sq ft is larger than average but
not huge, ours is the same size, built 10 yrs ago and we use about
2500ltr per yr, we don't have UFH though.

Advice to husband:
if she does that simply close the windows and turn down the heating.

Advice to wife:
if husband does that close the windows, turn down heating and make him put
another layer on. Nothing's simple with husbands.

Bear in mind that a new house will take some time for all water in the
fabric to dry out but your usage does seem very high. Are you sure you need
the same temperatures all over the house?

Surely you are not suggesting they too have someone who is both an expert in
everything and a legend in his own mind? (Perhaps he will go there to share
his contributions?)

I know of one really big old house 5 bedroom house, built around 200 years
ago so the only insulation was in the loft, which used that sort of quantity
but I'd hate to think that anything built new would use fuel at that rate.

Easy to check if you have a sight tube type gauge, turn off the boiler, turn
off the fuel tank outlet, turn on the gauge isolator if there is one and
observe over a day or so if there is any lowering of the gauge. If there is
a significant fall it will need urgent attention. If it is a small fall try
to ensure its not just thermal contraction effects



I'd say you have less than ideal insulation somwehere.

Quite!
