No problem. Also, if you fit the beacon, there's a link that you have to move to connect the battery in circuit, as it ships from the factory with the battery disconnected. It's all documented in the installation instructions.... when you install everything correctly, the little red dot on the...

Now that you've fixed your motor problem, you should really get the red flashing beacon that connects to the control box. Basically the motor shaft has an encoder fitted that sends a pulse back to the control unit to confirm that the disc is rotating. If the disc stops rotating for any reason...

I fixed the problem..... realized as soon as I got the rad removed, the cowboys who'd installed it tried to bend the 10mm pushfit piping back on itself through 90 degrees to get to the lockshield as the pipes natural run were both to the right.... of course it kinked and blocked the flow/return...

Hi, the two offending rads are in the same room and both have drain cocks on the lockshields. I planned to back flush up one and open the other, so the water should take the shortest path up, through the flow/return and straight out of the other one . I guess as long as there's no other path to...

Could I try connecting a hose from the mains to the drain cock, opening up another rad drai cock and back flushing the pipes ? Mat

Hi, been having problem with my CH system in a house that we've recently moved into. Worcester Bosch 34CDi combi, 12 rads, system is 2yrs old all piped in plastic. Long story, two rads downstairs dont get hot, one tepid one cold... completely bled all the air out, balanced up the system as best...

I've recently bought an old farm property that has been renovated. The original property used a cesspit for drainage, located some way off the house near the barns. During the renovation, they fitted a new Kingspan Klargester bio disc septic tank system for the drains with all new piping. I'm...

I got the rebuild kit from www.gas-spares.co.uk I think they're just called Gas Applicance Spares, based in preston. I think I still have the socket I'll check later. It's just a 3/8 drive socket that fits over the washer with the two cut out tabs (8mm or 10mm) I then just filed/ground down...

In fixed speed mode II or III that pump will have the same performance as the Wilo Gold 50 (or better) SO basically as long as you haven't selected one of the variable speed/pressure modes, that don't work well with modulating boilers then you should be good to go. Make sure you don't have the...

This looks very similar to the one in my ICI Caldaie Solar 80... I rebuilt that using a complete kit of parts that cost about £30. I had to make a special little tool using a 10mm socket, ground down with two little tangs to unscrew the main parts of the valve that holds the moving parts & O...

Hi I have an intermittent f1 fault on my glowworm 18hxi I've checked the firing sequence, and can see that the spark is healthy, the boiler ignites, burns for approx 5 secs, then stops, repeats this sequence two more times, then stops and shows F1. When it lights, it doesn't start to...

It was serviced last year... the combustion was checked at that time and adjusted correctly (after a new set of heat exchanger gaskets were fitted.... as stated in my original post. In fact after the new gaskets were fitted it only needed a tiny trim to get it within spec. My next door...

If anyone has any sensible suggestions, I'd be glad to hear them. If you're just bored & like typing...please don't bother :-)

Why would you assume I've never "bothered" to get it serviced ?? Yes it has been serviced.... that's when we replaced the heat exchanger seals with new graphite ones & checked the Co2 levels and cleaned out the condensate trap etc. This problem did not exist then, it's started recently Thx

Thx for the reply... I've listened to it a bit more, and it sounds quite like something's not quite right with the ignition sequence, the noise is more like a loud whooshing noise that lasts for a second or so as it fires up. If I could describe the sound, its a bit like when you try to...

Hi I have a CH system in our house (10 yrs old from new) 18 rads, fully balanced, Grundfoss 15/60 pump set on speed 3, open vented. System is spotlessly clean inside, has been flushed twice & drained in past ten yrs, always treated with fernox. Rads were balanced a couple of yrs ago, I...

Hi, I have exactly the same boiler and open vented system as you, had it for about 10yrs now... so have a bit of experience with it. I'm not a professional plumber or fitter... so I expect my response to get shot down by the experts..... but hey/ho :-) The pressure drop on these boilers is...

Yes, there is a gate valve on the HW return to the cylinder...it seems to be set about half way.. To be honest I haven't moved it because I guess if it's too far open then when the system call for both HW & CH then the flow will all go through the cylinder if that loop is a lower pressure drop...

Hi all....I've read some excellent info on this site, so I decided to join and ask for a bit of help myself. CH system in our house (2005 construction) is fully pumped, inc HW. Glow worm 18HXi condensing modulating boiler, 16 rads, all with TRV apart from one in the hall used as bypass. Main...
