Low Pressure - Heatline Boiler

Barrie

Hi Folks,

I'm hoping someone could shed some light on this one. I'm continuously getting the low pressure ( bar light ) on the heat line boiler. I usually let the letting agency deal with this one, but we've been left without heat or hot water all weekend in the stormy weather so i'm hoping i could fix it with some advice

I've done a search on the forums and found similar issues and tried to follow the advice given but i am still not too sure.

From what I read, I need to locate the temporary filling loop open it to allow the pressure to go up to 1-1.5/2 bars ( current under the 1 bar )

I also tried to search for the red handle filling loop valve also to try increase the pressure but since we don't have a hot-press, i cant exactly find it and its not under the sink either.

I found the silver coil pipe which is just under the boiler so i am assuming that is it ? There is a valve that allows it to open/close, so i tried that to no avail.

I've attached pictures to see if that is the filling loop, just wondering if anyone could shed some light?

Thank you,
Barry

On the valve on the left of the flexi hose use a pliers or similar to turn the brass bit in the middle 90 degrees so that it is in line with the hose.
Using a flat screwdriver slowly do the same with the slot in the centre of the right side valve, while watching the pressure gauge.
Put both of them back to their original positions when the pressure has reached approximately 1.2 - 1.5 bar

Thank you so much .

Just before i do it, are you referring to this brass fitting?


Thank you

No.
The bit slightly left of what you circled.

Barrie

Ah i see, the circular piece?

Thanks again,

Yes, the small brass bit sticking out of the valve.

Thanks again,

When you say it regularly drops pressure, how often are you talking about?

Barrie

Tried that and works a treat. Thanks so much Its great to have heating again.

I have been living here just over 8 months and that is the third time it has happened. By reading around the topic, it does sound like a leak and that's why its continuing to lose pressure i am assuming?

It's possible the boiler blow off valve is leaking, if you go to the boiler you should see a fitting with a red top on it, it's generally a 3 bar pressure relief valve with a pipe going to outside. Find the pipe outside and tie a plastic bag around it, leave it a couple of hours. If you come back and there's water in the bag then there's your problem. But as the other poster has said, it could easily be a leak.
Wouldn't be upstairs as you'd obviously know about it, if the pipes into the downstairs rads are coming up out of the floor then it could easily be leaking underneath, if they're coming out of the walls then they're on drops from upstairs down through the walls so it would kind of rule out a leak as you'd know by now
