Hi

Ive searched the net for an answer to a problem i have with my
worcester bosch 24cdi boiler but to no avail ! Rather then sign up to
some random diy forum i thought i might as well try here, and while im
at it i can see check out some savings accounts !!

Anyya, although the boiler works (or seems to) there are a few things
that dont seem right...firstly, sometimes when running the hot water
the water pressure will drop slightly and i think that if it drops
out on the boiler too much the boiler stops firing (?). We live in a
1880 terrace house and think that there maybe a poor water pressure
supply to the house anyway. After a short time the hw kicks in again
and 'pumps' it out at full force. Am i right in assuming the drop in
water pressure and subsequent re-firing could be due to the water
pressure coming into the house fluctuating due to neighbours using
the water? Or is there something else ?
Secondly and more of a problem is that if we turn the CH temperature
dial to below half and try to run the boiler, the boiler seems to
lockout and the CH light flashes and the
boiler fires, locksout, fires etc etc....Only when we turn the
temperature dial to above half will the boiler fire and maintain
heating the water. What could be causing this ? It is a bit
frustrating (and potentially expensive) that we cannot turn the
heating down to a low level as the boiler locks out. Any ideas ? From
reading various other posts the PCB is mentioned quite a bit but im
unsure.....

Apart from that the boiler seems fine-ish.

Any help or advice would be appreciated

Thanks in advance,

It is perfectly normal for water pressure to rise and fall during
times of heavy use.
This is particularly noticeable in the morning when people are getting
ready to go out.
As to part two.
The temperature of your home is best controlled by your wall
thermostat. Set the boiler to whatever temperature it is happy with
and let the thermostat do its job.
You need to look at this from two points of view.
One you feel most comfortable when the heating is on and you can feel
the infrared radiation from the radiators.
But, this is balanced by the need to run the pump/circulator more,
that uses more electricity.
Two run the boiler hotter, this means the pump runs less and you get
a noticeable swing in temperature up and down, and the down feels
colder. You save on electricity and loose on comfort. You also loose
on gas as the hotter the system the higher the heat loss along the way.
