you talk crap and haven't answerred my previous question!!!

are WRAs approved one better quality then? Used them once on low pressure cold/hot water to a basin. Any good for a direct system?

my point is: why a BLACK police force in UK? Whynot a white one too? Why do a UK couple get in troublr for kissing in Dubai? Why an asia police force in UK but no caucasian???

exactly, no answer. The BBC etc actually make people racist/feel racist; it is very sad.

Hey I know the Poles helped us in the war. My main point is: why does racism only work one way?

people not borj here or brought up here. Ie all the EU immigarants who are over here!!!!!

In London I'd say 60-7-% is foreign now, so so sad. Where were all these forigeners during WW2??

I disagree and stick up for poole. OK so how comes a UK couple get arrested for KISSING in public in Dubai??? (if religion doesnt come into it?? How comes we have a black police force/asian police force in UK but no caucasian one? We have a MOBO awards, a black footballers/newsreader award but...

is the bath secure and stable? does it move at all?

i suppose it could slow the flow down in any part of the heat ex and hence cause the overheat stat to trip...?? depending how bad the scale/sludge build up was? The newer boilers have smaller diamteter heat exchangers than the good old cast iron type's used to don't they. one other thing...

I see, I was thinking of ti from the isnide out.... I understand now, thanks for your reply. How would this then cause the overheat to trip then (as in some cases it has done).... a if the heat cannot get through to the water.....?

I have been reading posts and understand that a scaled or sludged up heat exchanger can cause poor heat output from the radiators in general due to the water in the boiler not getting hot enough, due to the scale/sludge. How is this so? Surely if anything it would make the water going...

yes i agree with you, BUT if HW is OFF at the programmer, there WILL be power to the grey wire anyway. If the programmer is faulty, and no power to the grey then you will be getting hw and heating!!!

yes correct HTG only on, HW off at the prog will be supplying power to the GREY WIRE. If HTG ONLY IS ON, grey will be live as the programmer isn't (v v unlikely) to be sending power to h/w on AND off terminal connections is it.

how am i showing myself up - check any htg/fault finding chart.... the grey wire thing is not mentioned in any of them. if there's power to white but not to ornage... the motor is not moving over... then there will be no power to grey with htg only on (as the micro switch won't operate...

WTF are you all going on about!!! If you put HEATING only on and there's power to the white wire but NONE to orange, it is a faulty motor / actuator OR the valve spindle could be seized up. If you say you have removed the head and the spindle turns alright, then it is a motor or actuator...

ok thanks. so 3 wires, 1 from the s/l, 1 to the main solenoid and 1 to the dial/knob (the capillary tube)

sorry, one more boiler stat question whilst i'm thinking of it :) there are 2 wires to the stat phial, the sl in and the return to the main solenoid correct? when you turn the dial/knob to increase/decrease the boiler stat setting/range, how does this open/close the contacts closer/further...

thanks for your help. i feel embarrased now for not knowing this :( of course a boiler stat can fail without another system fault!! it's so basic!! i'm just trying to learn about boilers as they interest me. i've done some basic jobs in my house and for family, and diagnosed faults using a...

it's the heigh from the cold water tank (go from the bottom) to the shower rose. you want with most showers at least 1 metre, or a pump will be needed. some showers use only 600mm head but flow may be poor/poorish.
