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 ?

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?

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

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.

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.

Piffle.

We have a big, exposed house and get through about 1300 litres a *year*.

Big and exposed are relative terms.

Most peole I know in similar sized houses (about the size of 3 or 4 so
called 'family' 4 bed houses) burn the same sort of fuel rates as I do.

Agree - Fathers house has 6 bedrooms, is an irregular shape (big wall area for
the accommodation, old house, poor insulation, no wall insulation, Aga on for 6
months, and he uses about 1200 litres a year. Its generally comfortable, though
not "hot" inside.

I think the irregular item is actually the shape of those inside. A
divorced friend got remarried and usage jumped by 200 %.

This one clearly doesn't know too much at all. I think he is a spammer of
some company to promote or dicredit something. There have been too many of
them on here lately.

No spammer here Dr Freezing as the email return address is totally
valid (unlike yours I suspect) I've been on Usenet in one form or
another for around 15 years and despise spamming. I have used the same
email address for around 10 years now and after some slip ups in the
past now need strict email filters. But before you email me details of
your books 'how my life was changed by the combi', 'boilers I have
known' , 'two is better than one' and 'ice cold in grimsby' the
address that is used on Usenet postings is routinely dumped.

I sell, and manufacture a premium product but nothing that I suspect
would remotely interest anyone in this newsgroup, nor is it a
competitor to anything that anyone, including you, have to my
knowledge ever mentioned in this newsgroup. Indeed there are possibly
only two very low volume newsgroups that might be of interest to my
customers yet I post to neither.

But i'm totally convinced by the combi boiler Dr Freezing. So much so
i'm fitting one in the next couple of weeks. But before you get
carried away and ejaculate in your shorts i'm moving house shortly
afterwards so some other poor sop can fill their bath in around 25
mins while mine fills to the brim in less time than it takes to have a
huge morning fart, scratch my arse, have a ****, clean my teeth and
have a shave. Some days when I need an early **** i'd prefer it to
fill a little slower.

To keep this remotely on topic can you tell me how I convince a future
house buyer that a "12 litre per minute 35 deg rise combi" is suitable
for anyone who ever takes a bath when, and this has been accurately
measured, my boiler gives me a litre of water at 60 deg C every 4
seconds from a 8.5 deg C supply. Give me something like that in a
SINGLE boiler casing of around 600 x 450 x 350 and i'll buy a hundred
of the things off you at your cost plus 50%.

You doth protest too much. You are spammer. Come from nowhere with venom.
There are a few here and Speedfit had one here to do the same thing.

You are irresponsible and a shark. You could have installed a high flowrate
model, but picked an inappropriate model. I hope the buyer sees this and
drops the price accordingly.

It is if you want to wait, normally this is unacceptable. Do not try and do
a bull**** job on an unsuspecting buyer. Rip it out now and put a high
flowrate model in, or install another combi and combine the outlets for the
bath.

You are obviously going to mislead and lie trio sell your house.

when, and this has been accurately
measured, my boiler gives me a litre of

15 litres/min. Not a lot. Two combi's coupled together will do that; nice
and neat on the wall. Fabulous.

600 x 450 x 350 and i'll buy a hundred

They are there Mr Spammer, look at Takagi and Rinnai who are the big
players. The largest output instant water heater the world is a Takagi at
50 litres per minute at 380,000 BTU/hr. Yes 50 litres/min and never runs
out. Fabulous!

I openly admit I don't know much about UFH, why else would I be asking
for help/ideas - I didn't install it. All I have is a room stat in
each room to control the temperature. I have tried to contact the
builder but he has got the money and does'nt give a damn.

And no actually I'm not a spammer, just someone who has excessively
high fuel bills. What exactly in my original message did I try to
