Cheers Dan. Any recommendations on clearing the air out. I've tried opening the rad bleed valves but all I get is water! Not sure if this is relevant but I've shut off most of the rads thermostatic valves as we don't want to heat those rooms but if you think I should open them all up then let...

Hi All, We had a gas engineer come to fit two new zone valves. It took him ages to try and get the air out of the system. The issue now is the boiler stat trips every few minutes so something isn't right. It's a Potterton Prima 60F. Could it be air still trapped as I heard one of the...

Hi All, I'm repainting my kitchen walls. I started with the wall and ceiling edges cutting in with a brush. I then switched to a roller for the main bulk. The problem is the edge finish looks different to that of the roller finish. I've only put one coat so far and it'll need at least two...

That's probably true Tony but we are where we are with this I'm afraid. All indications would point to a faulty zone valve or microswitch. Would you agree? Cheers Daz

Not sure you can remove the heads on these Tower valves unfortunately.

Hi All, Having had no end of trouble with my central heating I made a concious effort to see what is causing the CH not going on (HW is fine). My HW zone valve makes a click when fully opened whereas the CH not only doesn't seem to move as far but there is no click. The valves I have...

I've put the old programmer back and the room stat now has power. Don't think the new one was wired correctly by my pal. Now I have the pump running when selected HW and no pump running when I select CH !

Just discovered that since changing the programmer the room stat has no power!

Had a busy day and only just took a look at the zone valves. The HW valve indicator arm moves a lot further then the CH one. I also noticed the CH valve when opening or closing moved the motor at it's stop position as if it were a little loose. I'm thinking that one of the microswitches is at...

I'll have a look tomorrow morning Tony and let you know. Do you think it may be the pump or perhaps the valve microswitch?

Think we've got it down to something to do with the switched live but for the life of me I don't know why the boiler now fires up but won't turn off!

Hi Tony, Brand new programmer (probably not needed!). The CH motor was very hot as well the other day before I could get the boiler to start and all the pipes were cold. Could it be that there is something wrong with the microswitch in the CH valve or the motor? Daz

This was hot not warm. I don't mean so hot I couldn't touch it but almost! What could cause the demand for CH on if the room stat was off?

Not sure if this is important although it probably is but the valve motor on the CH side is very warm / hot!

Well I left everything off and this evening had the intention to check the switched live in the junction box next to the valves. I turned the programmer on and selected central heating and low and behold the boiler is giving fired up and the rads are getting hot! Then I dropped the...

Thanks. I'll have a look tonight when I get home from work. I can move both valves manually with the small lever at the top of the valve. Is that an indicator that the valve is ok? I've replaced at least one both motor on the valves and yesterday one of them was buzzing slightly and was getting...

what confuses me is what device sends the call for heat to the boiler?

All wires tight.

I have 2 x 2 port Honeywell (I think they're Honeywell) valves

Bought a PCB and a new programmer! I'm mad! Going to take them both back once I know what's causing the problem.
