Chucky Mama Posted November 28, 2009 Share Posted November 28, 2009 We have just had our new windows put in and was hoping to be sitting in a toastie warm house this wekend but our radiators aren't behaving themselves. How do I bleed them properly. Do you do it with the heating on or off, do I have to dothem in a particular order etc.. Thanks for any advise Quote Link to comment Share on other sites More sharing options...
Ain't Nobody Here Posted November 28, 2009 Share Posted November 28, 2009 I think the heating has to be off (but I may be imagining that!). I would have an old towel or flannel to hand as the water that comes out if you don't turn the key quickly enough can be black and horrible . I just do the ones that seem to be not working first!

Egluntyne Posted November 28, 2009 Share Posted November 28, 2009 YS...a plumber......says: Before you start and after you finish, make sure that the pressure in the boiler is set to one and a half. Heating on or off it doesn't really matter. Do downstairs first, then upstairs. Have a small cloth ready and let the air out till water starts to trickle. Good luck.

Blackrocksrock Posted November 28, 2009 Share Posted November 28, 2009 We do ours hot and the air will come spluttering out and then the warm water then you shut the valve off again - do you have a key? Quote Link to comment Share on other sites More sharing options...
Chucky Mama Posted November 28, 2009 Author Share Posted November 28, 2009 OK, thanks for the advise the radiators seem to be working now. Is it best to have the heating on all day rather than having it coming on and off during the day in terms of keeping the house warm and economy?

Egluntyne Posted November 28, 2009 Share Posted November 28, 2009 YS says it depends on so many variables, such as the age and type of boiler, the level of insulation in your home etc. Quote Link to comment Share on other sites More sharing options...
Ain't Nobody Here Posted November 28, 2009 Share Posted November 28, 2009 That's useful info, Egluntyne . But, how do you set the pressure on your boiler ? Is it just the dial on the front? I always thought that was temperature! Quote Link to comment Share on other sites More sharing options...
Geoid Posted November 28, 2009 Share Posted November 28, 2009 It depends on your boiler. Read the instruction manual for it. Quote Link to comment Share on other sites More sharing options...
Guest Posted November 28, 2009 Share Posted November 28, 2009 I don't have radiators any more which is a shame because I take after my Dad and like sad jokes. So bleeding the radiators always opened the door to "wheres the bleeding key" type jokes! Quote Link to comment Share on other sites More sharing options...
Charlottechicken Posted November 28, 2009 Share Posted November 28, 2009 That's useful info, Egluntyne . But, how do you set the pressure on your boiler ? Is it just the dial on the front? I always thought that was temperature! Let more water into your system if you want the pressure higher, if you want less pressure bleed a radiator . If you bleed the radiators, make sure the pressure is at least 1 bar when you have finished otherwise your heating may not come on again after it goes off. Most boilers need a pressure of at least 1 bar to come on from cold. I bleed my radiators whilst on and use a cup as I find some trapped air splutters out with water. Then I check the pressure is at least 1.5 bar (when heating is on) so I know it won't drop below 1 bar when cold. Quote Link to comment Share on other sites More sharing options...
The Dogmother Posted November 30, 2009 Share Posted November 30, 2009 I do as CC and Egluntyne have said. Regular job in my old house. Lying on my back in the sairing cupboard to repressurise the boiler is NOT my favourite job, especially as the cat always thinks I am playing and comes to walk all over me!

The Dogmother Posted November 30, 2009 Share Posted November 30, 2009 My combi boiler has a key that fits in underneath the boiler, you turn it to let the water in and then off again when the pressure dial has reached the right point. Just don't lie under it as some water always comes sploshing out when you remove the key! Quote Link to comment Share on other sites More sharing options...
BarbaraJ Posted November 30, 2009 Share Posted November 30, 2009 Lol all too technical for our boiler as its behind the gas fire in the loungeall it has is a temp dial at the front. Very old and we keep getting told to replace it as there may not be spare parts if we need them. Ermm they have been saying that for over 10 years and nothings gone wrong, if it ain't broke don't fix it!! Quote Link to comment Share on other sites More sharing options...
