filling loop
In Riemannian geometry, the filling radius of a Riemannian manifold X is a metric invariant of X. It was originally introduced in 1983 by Mikhail Gromov, who used it to prove his systolic inequality for essential manifolds, vastly generalizing Loewner's torus inequality and Pu's inequality for the real projective plane, and creating systolic geometry in its modern form.
The filling radius of a simple loop C in the plane is defined as the largest radius, R > 0, of a circle that fits inside C:
If you are qualified to do a Gas Safety check on a property I assume that entails checking the boiler.
If, when checking a Combi, you notice the flexi filling loop in place (Taps closed) would you remove it or leave it be?
Also if you notice one valve open and the other closed, once again, would...
Hi Folks,
Where is the place to order a Vaillant filling loop, please? I looked around on the net but can't seem to find it as a kit. I'm not doing the job but he wants to know what to buy and replace it himself and asked me where to get one. I said I'd have a mooch. He sent this picture. I...
On my Valliant eco tec boiler the pressure guage is on red when cold . I drain a radiator to correct to pressure and it works fine and stays in the safe zone . When I switch boiler off the next day it’s back in the red
It could be one of the valves leaking .
Can I take the loop off , which...
I’ve noticed on my old Bosch boiler the DCV on the filling loop is fitted to the boiler side of the water supply.
And there is no isolator valve fitted. The only thing stopping it from leaking is the DCV?
IS this ok?
I’m doing a bathroom refit, and there’s some strange pipework design that I’d like some advice on, please.
I want to remove the cold water pipe running through the loft space because I would rather avoid having a cold water pipe buried under the loft roll insulation.
Instead, I’d like to reuse...
Hi, We‘be recently moved into a property with a very old Potterton statesman. My husband bled the radiators last night…and since then he’s called all sorts of problems! There is now only one tiny radiator with heat in it. There is no pressure gauge on the boiler , I can’t find a full loop on...
Hi all
Moved to flat recently, and the heating is not very good. I realized the pressure is too low, below 1 bar. It is Meibes, product number 10920.26 OH5
So I am looking how to fix it. I am only a DIY'er, so bare with me.
In the diagram you can see the fill loop mentioned, but that is not...
Any idea why the pressure keeps going up on my combi boiler? I have a Vaillant Ectotec Plus about 15 years old. The heating has been off all summer and the filling loop taps are both fully closed but the pressure keeps going up. I empty about 2-3 litres of water from the system every 2-3 weeks...
Hi, I have recently had a water board inspection
This is what the report said about the filling loop on our press unit for a biomass boiler….
There is quickfill pipework directly between the mains water supply and heating supply. This type of temporary connection is permitted under the water...
Hi Guys,
The valves on both sides of my Valiant 837 filling loop are letting through causing a constant pressure rise (seems to be a common problem). I want to cap off or isolate the small connector but its not a size I recognise, the part number for the filling loop is 0020010293. Can someone...
Hi Everyone, hopeing someone can help
We have a Greenstar Ri Boiler and its lost pressure, pressure gauge on top of the boiler reads 0.6 bar and i know this should be around 1.5bar, there is no external filling loop near the boiler or in the hotpress, there is a pipe in the hotpress with a red...
I hope you can give me some advice.
The day after a pump replacement last week, on my Halstead ace, the boiler and pipes made a hissing noise when the hot water taps were used - a noise like when the pressure is too low- this continued when the taps were turned off and until the boiler stopped...
The central heating circuit is slightly low on pressure so I tried to top it up with the built in filling loop. Nothing happens. No mains water gets pushed into the heating return pipe. I disconnected the filling loop on the heating side to test the double-check valve, and mains water comes...
Just wondering if there are any issues with adding water to a UFH via the boiler filling loop… reason being wanting to flush out some gunk from a loop and ventilate but don’t have access at the moment to proper hose connection adapter so I can plug mains water at the manifold.
Was thinking to...
Hello - I have an f.22 error on this system boiler, 0.4 bars. Just moved into this house so not certain on how everything works. There are no taps under the boiler to add more water.
There is a hot water cylinder in the cellar so thankfully it's just heating that we have lost.
With this...
Hey!
I'm having a bit of trouble with my boiler. I was hoping that someone could help!
Error F22 is displaying and I need to increase the pressure. I've tried this but I'm having a bit of trouble. My understanding is that I need to move both valves in a direction that results in water flowing...
Hi all, I think has been discussed before but I don't think I've seen a clear answer. We have the Vaillant boiler as above and the filling loop has started to leak from around the olive joint on the cold water side.
I would like to replace the whole loop, flexi, taps and the valves etc.
I can...
