Help! Bled the radiators now heating not working!

Nottoobadyet

Hi everyone -

We have an ideal ICOS boiler in our rented accommodation. As its starting to get a bit nippy, we bled the radiators as they had been getting warm but not hot. Now that we've bled them they are cold as death and the boiler has started making strange noises! Yikes, how did that happen??

Thermostat is on high, we hadn't changed any boiler settings but I've checked and they are on for both heating and hot water. Water does seem to be heating up. The airing cupboard doesn't seem to be getting hot either. The boiler displays a "c" when turned on. There's a small dial (maybe for pressure?) underneith the boiler which is now on zero.

What have we done!! We made sure that the radiators closed completely after we bled them.

Sounds like you need to top up the system.......that gauge should read 1-2 bar......try find where the water supply goes into the boiler and there should be a isolator valve which you turn which will top up the system.......do this with the boiler off......and turn the valve back off when the gauge reaches 1.5 bar !!!!!

You need to repressurise the boiler,there will be one or two taps under the boiler,the dial should be between 1 and 2 bar,don't go over.

Thanks both for the quick responses!

Under the boiler there are three things - a plastic tap that can easily turn with my fingers, which drips (clean) water when I do. There are also two places that you could use a screwdriver to turn, one of which is connected to the plastic tap.

Any idea how I work out which one is the right one to use?

It will be the plastic tap,need photo to be sure,if it's dripping it needs fixing as the pressure will keep dropping

Some filling loops drip (they shouldn't) when filling the system. If it doesn't lose pressure when the loop valves are off, don't worry about it too much.

Pressurise it to just over 1 Bar, bleed the rads again, then check the pressure is just over 1 bar again.

These boilers don't have a pressure switch to cut them off if the pressure gets too low.

As I open the plastic tap, there is quite a drip but I don't see the pressure meter budge. Its not even really a tap - just a round bit of plastic with a place for the water to come out underneath. Sorry for the poor description!!

The water is also quite warm, which makes me think it may be the "out" water supply, not the one bringing water into the boiler if that makes sense? Its off at the moment but was on this morning.

There's also a place that can be moved with a screw driver attached to the pressure meter - could that be the one?

Here is the view of the taps Im referring to. The one that drips considerably when opened is the white one on the right.

Hi

Step away from the boiler . You're playing with the wrong bits.

That's a drain point.
You need to get a spanner on the joint under the pressure gauge at some point, it's been leaking.

You are looking for a filling loop.( Google it. It's probably in the airing cub.)


Edit again... A photo of the airing cub. would be interesting as well.

Still the wrong bits.

Do you see a stainless steel flexible hose anywhere?

Why don't you contact the owner/landlord.

Looking at it again it could be the one buy the gauge but I am not sure. Do you have the manual?
