Hey everyone, ive checked the FAQ's and cant really pin point my problems. I have 2 as below:
1) I have a small boiler heating up an indirect cylinder, with the usual cold water storage tank to the loft space also there is a F&E tank all full and in working order, now the problem is im getting absolutely no hot water (not even a drop) out of my bath taps and kitchen sink !!! cold water from the bath is present and fine, could this be air lock or a blockage of some sort, if so how do you clear them?
2) Dont know if these are linked but when we put the hot water on for heating from the programmer, the boiler fires and heats the water in the cylinder which is ok but also the heating in the rads get hot too even when the central heating is off from the programmer, could the motorised valve have gone?

please help cheers, much appreciated

Hi Seco,
yes its a 3 port motorised valve but its navy blue in colour if that helps, probably stuck in neutral position I would think, do you agree?

How do I clear the suspected air lock from the hot water pipework?

Cheers mate

could be a switchmaster or horstmann.
has it a name or model number on the casing ?

no.

when hw on only check all outlets of the valve hw/heating if they are all hot as far along the outlets as you can feel then the valve is not shutting fully.

could be crud in the port or the paddle is faulty.

have you a mixer tap in the kitchen or bathroom ?

if you can open the hot fully put the palm of you hand and block the spout and open the cold tap, not to mad or you'll be soaked.
the cold will push the hot backwards and push any air out.

hold it for about a min then remove palm and shut cold the hot should carry on running then open the other hot taps.
