RE: completely OT, Combi Boiler help/advice

[Evans Tom <tom.evans@xxxxxxxxxxxxxxxxxxxx>]

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 the main
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.
