• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Another challenge for the grey cells

I commissioned this gizmo to get me out of a 'hole'. It's saved me an awful lot of work on several occasions and solved the problem. Why ?

All good ideas but all the suggestions are usually available with a standard installation. For example, filling rads from a header tank in the loft.
 
I'd have said it was to attach a hose to thoroughly flush all the old oxides and gunk out, but that's what Ian already said.
It must be something you fit temporarily and then remove or else you would need more than one.
 
^^^ Wot Eee said.
But I usually just whip off one of the top plugs and use a short length of garden hose and a funnel.

It;s the PTFE tape and 1/4" (?) pipe thread I can't fathom, unless it's something to do with one of those goo kits (jelly-like corrosion inhibitor rather than liquid).

But you have said you have an unvented system so it cannot be for filling or adding inhibitor unless it attaches via some valve. It does look like a temporary get around and the answer must lie in that 1/4 BSP thread that is needed to attach something to something but only briefly while some operation is performed. It is also worth saying that unvented heating systems in the UK come under G3 of the building regs on the grounds of safety, think of what would happen if you heated 150 litres of water from say 5 to 55 degree's and there was no room to accomodate the expansion !

An incorrect assumption Roy. The gizmo is not relevant to the current property.
 
The thread and ptfe could be a red herring if there is no hole and you use it to blank off existing compression fittings?

Creative minds on this forum :)

Unless someone cracks it, I'll reveal all tomorrow
 
Screw into top of radiator, apply bike pump or some such to displace the water with air, close the service valves, radiator off without mess for decorating ?

Now that’s a mighty fine idea!
Except the radiators in my house now don’t have water in them! Clue if it helps is that there is only one pipe to each rad.

I like that idea a lot. 👏🏻

And you are the closest yet. Inverse logic perhaps is the answer ?
 
OK.

At the house before last, the central heating system had a humdinger of an airlock every time the radiators were drained...the house was another 'do-er-upper' and also knocking the two halves back to it's original design so lots of temporary works, partial CH etc etc.

The pump pressure simply wasn't enough to force the water through and push the air out to somewhere useful. Like the top of a radiator. I realised that I needed a higher pressure. Mains pressure but how to get it into the system? 💡Hence the gizmo and it worked very well.
