Thanks for all the replies, to summarize I will hardwood dowel (3 X 12mm) and D4 PVA Everbuild glue from toolstation. The two halves sit tight together (dry run) so after I glue it possible to reduce the line of the break that is noticable?

Thanks for the replies, I have the "blue"PVA I also have some two part epoxy resin left (used that for gluing the joints) which would you use? I don't think I will dowel it as the break is in an area on the chair that should not get much force. Re; water ingress and fungal stain how do you...

Sanding an outdoor rocking chair ready for this years varnishing the chair fell off the worktop and broke off part of the back (see pix as was and as is) The wood is sapele. initial thought is to plane / router the two edges square then glue but that would loose height causing a step at the...

My existing boiler is a four pipe with internal diverter valve. The cyl.zone valve (240V) opens it's auxiliary switch and the grey and orange wires from the zone valve connect to the boiler's 24V rail to fire the boiler. The connection between the boiler and the cyl zone valve, 9 mts away, is...

Picasso can you send your message again, I read it whilst out (alert on my mobile) now I am back home I cannot retrieve it, your name is there but not the content which did make interesting reading. Thanks

Thanks Ian, It probably explains why Viessmann want a demand box (240V in 24V out) as that box must house the relay you describe. Back in 2002 when I had my boiler installed they didn't bother and it has worked ok ever since.

I have a Siemens zone valve in use on a DHW cyl that is priority demand to a four pipe gas boiler the wiring is configured as follows; When brown is live (240V) the aux switch creates a circuit between Grey and Orange. On my boiler Gr and Or connects to the boiler's 24V DC terminal strip. I am...

Thats sounds expensive are they sending screeders and installers to put it in? I have always used "UFH1" a Doncaster supplier, . If you visit their web page and look at their UFH kits I would presume you need the following, One number eight port manifold (six rooms, incl. utility, have one...

That 30mm isn't going to be an issue with air but if you have concerns give the utility it's own loop (circuit) eight port manifold I have had my UFH in use since 2000 with no issues re; water quality (alway keep plenty of inhibitor in the water.) The insulation thickness generally can be...

Thanks, Meldrews mate The pipework mods, replicating what is at the manifold, would be after that manifolds zone valve that is sited in the plant room and is marked up to distinguish it from the other heating and DHW zone valves on the primary circuit. The existing TMV(s) have no identification...

Hi, Rob some observations on your thread. The position of the manifold is ok but be mindful of the noise from the pump, valves and pipework (where is the boiler?) My son's is in a plant room in the utility with the boiler and cylinder and there is noise / vibration from pipework that resonates...

Thanks Crezzer I have new valve parts that resolve the issue keeping the existing valves in the manifold kits as supplied. To change the TMVs in the manifolds isn't easy because the existing valve bodys are different from alternatives ie, Reliance. There has been issues with the manifold TMVs...

I have two number UFH 12 port manifolds supplying the required heating around the house, both manifolds having issues with the TMVs not giving constant water temp causing the heatmiser room stats to cut out on floor overheat. (don't know the manufacture of the valves only the supplier...

Andrew, the link shows a UPM3 Auto L25-70-130 is that a direct replacement for my Alpha (1.5" connections 5/6 mt head) It is certainly a cheaper option. Thanks

Please advise, I need to replace a 18 year old Alpha UFH manifold pump and see we are now on Alpha3 Are there enough benefits upgrading to an Alpha3 pump to warrant the extra money? My heating system has ten loops (total design flow pressure 3.52m head of water) Your comments appreciated

Thanks

Thanks gas guru How does it vent in the horizontal position? Just curious Paul

Come on lads & lasses in the know re; wilo pump a is it good value? b OK in the horizontal plane? (are there any lady heating engineers on this forum?)

I have a fall off in l/min flow of water in my UFH circuits which, I think, is a 18 Yr old Grundfos Alpha pump issue (circuits balance valves opening correctly, one zone (lounge) requires 2.4 l/min in two loops but cannot achieve more than 1.2 l/min on both circuits, no obvious air issue) I am...
