Help: Intergas Boiler: Has my filling loop been installed

Mr S · Mar 22, 2019

Hi All.

We've woken up this morning to zero hot water and my diagnosis is that the (Intergas HRE Compact SB) boiler needs to be repressurised. (It's only a year since install, so I'm a bit surprised but...)

We didn't have a lot of handover from the installer and, having taken a look, I'm concerned there is no "filling loop" installed. I'd appreciate expert confirmation of this.

I've attached four photos which show from the bottom of the boiler down to the pipes. (It should (I hope) be obvious which are which).

I'm more than comfortable doing any repressurising myself, having done this many times with our old one. But, I can't see any obvious filling loop and I suspect this means calling in the cavalry.

(I'm reaching out to this board as we did not depart on good terms with our plumber after a bit of a UFH disaster (also discussed on here)).

Many thanks in advance for all your guidance, Steve.

Have a hunt in cupboards Steve, can sometimes be hidden away.

Hi Steve,

As RPM has said, but there isn’t one on those pics by the look of it, unless it’s part of the one that is in plastic? Also I take it you know the boiler is on and it’s showing as low pressure?

Thanks. But, presumably it needs to be close? The pictures above show all the piping moving from top to bottom. To the right of the bottom image is our (plumbed in) washing machine and to the left is the outside door.

Many thanks.

Where is the pressure gauge?

Thanks. Yes, see attachment. I did a bit of desktop research and "0.2" is indicative of low pressure and the need to repressurise. I think.

Many thanks for all your help.

Hi. See other attachment below. It is on the LED.

See details here:

(and page 11 - faults).

Many thanks, Steve.

Yes that indicates low pressure. You need to find that filling loop, it shouldn’t be too far away, but have found them in a cylinder cupboard with the boiler in the kitchen

A weird install that one

Like this? Is this the filling loop do you think? (found by the cylinder).

Thanks.

Thanks. See my latest, pic. on another comment of the cupboard where the cylinder is. Is this the filling loop?

Thanks again.

Yep , its the braded hose with two black valves , one is open already, be sure you turn them both off when you are done .

As per Townfanjon, yes that's the filling loop. Should be able to look at White gauge, looks similar in pressure to your boiler.

Mr S · Mar 22, 2019

Thank you All. Have followed advice re the filling loop and everything now seems to be charging up. Phew! Many thanks again.

Remember to turn it off again

If you are feeling brave and more confident in your plumbing skills, now is an good time to top up the inhibitor!

Strike while the iron is hot!

I think I have the same problem as you and wonder if you can help. we have just moved into a flat with the same boiler and I can't find a filling loop. Pressure has dropped to 0.4 although can't find any leaks. But the missing filling loop is driving me insane. I can't access your photos. I am attaching mine. Can anyone help??

Hi. Do you also have a tank? If so - try there (it’s where I found mine). Else, as someone advised me, you might well find it in a “nearby cupboard”. The clue should be the metal flexible ridged piping with a pressure meter nearby.

All the best, Steve.

Thankyou so much for getting back to me Steve. And so quickly! I found it!! Miles away in a cupboard where there used to be a tank. Phew.
