RE: completely OT, Combi Boiler help/advice

["Tawn, Jonathan" <jonathan.tawn@xxxxxxxxxxxxxxxxxxxx>]

Gent's, et al,

Many thanks for your advice ... I thought I may have knocked something when
I drained the system ... but as I shower rather than bath I didn't know how
long it had been like that..

Just out of curiosity though (and I know without seeing the boiler it may
be
difficult to advise) but would there be a valve / adjuster of some descript
I could adjust to 'fine tune it' so the boiler will heat as much water as
possible... (would turning up / down the hot water temp work??) or if I
turned off the rad's would that make a difference ?

Thanks again for your words of wisdom !
Jonathan.

help/advice

Jonathan,

I have just moved into a house with a combi and
was sure that
there was a problem exactly like you described, I have good
old British Gas
out to check it over. He said there was nothing wrong and
that the reason
you have to reduce the flow rate is that by law a Combi can
only heat up
water by a maximum of 35 degrees, so, if as the other reply
says you have no
cold water tank in house then the water will come straight
>from
supply in the road.



NOW FOR THE Logical bit that made it all fall into place.
(Thanks to the man
in a van)



In the winter the water supply from the street is delivered
to the combi at
around 3 degrees above!!!! In the summer it comes in at 13
degrees above.
Hence you can fully throttle the hot in the summer and still
burn your bits,
where as in the winter you have to throttle it back to keep
the water toasty
and warm.



Hope this helps



Tom

Hi Chaps,

I know this is way off-topic, but I wonder if any of you
could shed some
light on a problem I've got with my combi-boiler.

If I turn the bath tap open fully, the water eventually
turns cold - but if
I turn it say half way open the water remains at the right
temperature(hot)... the same also happens with sink taps,
but the water temp
drops by a few deg's rather than turn cold.

As I shower all the time I hadnt really thought about it
until the g/f
wanted a bath... so I'm unsure as to how long its been like
that.

Any thoughts / advice on how to start 'trouble-shooting'
would be an immense
help.

Many thanks,
Jonathan.
