2006-12-29 03:12:45 · update #1
the make of the boiler is Vaillant cant seem to find any more info than that?
I am able to light the pilot.

a bit of a silly question but what does the tap look like and where abouts could it be please?

First switch off your boiler (the electricity, not the pilot light) and then check the pressure gauge on the boiler. If the pressure is below 2 bar you need to top up the water level using the water loop system (a small tap) which is attached to your boiler. Top up to a maximum of 2 bars. Now switch the boiler back on and let your boiler complete its own automatic safety check. Now try your hot water to see if this process has been successful. You may have to bleed the radiators again to remove any trapped air, but do not open the valves on all of the radiators at the same time, just do them one by one, as the pressure will drop on your boiler again if you do them all at the same time. When bleeding the radiators tighten the valve back up as soon as water appears at the valves. OR, maybe your pump has packed in.
To find the tap locate the point where the cold water pipe enters the boiler and it should be some where around here. (The tap looks similar to the kind that you find on the back of a washing machine where the cold water supply feeds in. It may be black, silver or white.) Hope you succeed with fixing the problem.

If its a combi boiler you may have let out so much air that the pressure has now dropped too low, and the boiler will now not work, you will have to raise the pressure on the gauge to about 1.5 bar. using the filler loop. OR post the type of boiler/system you have for more info on what to look for.
ADDED>> Vaillant model?? First check and advise the reading on the pressure gauge?? The filler loop SHOULD be a flexible metal braided hose with a tap/valve at each end, usally fitted below or close to the boiler between the mains water feed and the heating return pipes, it SHOULD be disconnected after use but they seldom are! You will have to open both valves, but keep you eye on the gauge as you fill.
You have added that your boiler is working, but there is no hot water or heating, do you mean that it is firing up/ burner is lighting? If so where is the heat going? Is the pump running ?

Sometimes bleeding a radiator does not cure the problem of it not getting hot, if this happens and the radiator has never worked since it was installed or last removed/refitted then: Check that the shield valve is not closed down too far. Check that if a thermostat valve is fitted, it is on the inlet to the radiator not the outlet - these types of valve often need the flow of circulating water to lift the valve off its seat. If the radiator is not getting hot but it has worked fine at sometime since any work was carried out: An air lock may have developed in the pipe work. The inlet or outlet of the radiator may have become blocked, Try opening up both the control and shield valves (count the number of turns on the shield valve so you can reset it). If all else fails, the radiator will need to be removed and the individual components checked for any blockage.

If you look underneath on the right hand side in the front you should see a small lever which can only be turned quarter and the pressure should go up. Don't let the pressure go up above 1 and a half. You have to bleed the radiators again, but make sure that you don't let the pressure drop below 1. Top it up after every boiler you bleed.

Turn off boiler. Go to last radiator open valve and leave open.
Go to first radiator open and drain for about 10 minutes.
When you turn boiler on make sure the circulating pump is working.If the system is old it may have to be flushed.
If the first two radiators don't get heat within about 15 minutes then you will have to have the system checked out by a heating contractor.Good Luck

Go to the furthest radiator from the boiler and start bleeding the air out..Work your way back to the closest radiator bleeding all the air out...Most of the ones I know of have pop off valves on them already,,so they should bleed themselves,,if you are getting sufficiant heat... Sounds to me like you have a vapor lock in the system...If you are getting sufficient heat,,just hurry up and wait.....

Check is your boiler is working first

check your temp gauge on your boiler if it has dropped use the filler loop up to about 2bar

No! You must have done something wrong.
To bleed the radiators means to let trapped air escape. It seems you have let all the water escape too!
