Thanks for this - really good advice. (1) - I think you may be right that it is a one pipe system. Do you think I should attempt through trial and error to get the radiators that are nearest hydraulically - which I think are the upstairs ones as they get heated first) to a lukewarm...

Hi, I tried to balance the raditators in the house that we're renting. The system is an old hot water tank system heated by an oil boiler. The valves are lockshield valves and wheelheads at either end. The upstairs radiators are closest to the hot water tank. Essentially I want the downstairs...

Yes but which ones do I turn? I tried turning the upstairs lockshields completely off but that messed up the whole system

HI, The central heating in our house is a hot water tank system. The radiators have lockshield valves and wheelhead valves. We want it to be hotter downstairs than upstairs. At the minute all valves are open. The hot water tank is located upstairs and the upstairs radiators get really hot but...

Hi All. Thanks for all your help. I think I made a mistake. I didnt want the heating on upstairs so I shut all of the lockshield valves. But this seemed to inhibit the radiators getting hot downstairs (I thought it would be other way round). So I've gone back to square one. I have opened up...

I have opened up all the wheelheads and will adjust the lockshields once I know which radiators heat up/dont heat up and which ones I want to stay cold, etc. It looks like the boiler is still in demand. Room is fairly standard size (3.5m x 3.5m x 3m). In the house all but one radiators are...

Here are the pics of the valves of the radiators in the room with the thermostat 1. Upstairs radiators. These get very hot quickly. I have either turned the lockshield valves on these completely off or slightly open. These are all ok as I want them to be luke warm. 2. Room with thermostat. Both...

I put a thermometer in the room and the actual temp was reading 17 degrees celsius (63 degrees fahrenheit).

Thank you for your advice. It worked in that the cold radiator heated up. Now I have tried to balance the system. Its been quite difficult to do as I dont want every room to be the same temperature and it seems that the slightest turn on the lockshield valve can have a big effect. Ive turned...

Hi I tried your advice and turned off all the radiators except the one in question and it heated up like it should do. What does this mean then? What do I need to do to rectify it? Obviously need to turn the others back on now. Also is there any way I can check the pressure. Just want to...

Hi, I have recently moved house. We have one cold radiator in the living room - the other one is fine. I've bled it and opened the valves on either end - still nothing. I went to check and up the pressure of the boiler and it appears we have a mega old boiler that I'm not exactly sure how to...

Someone told me to use LSX Sealant. Would that do the trick?

Hi, I have a glow worm boiler (I'll confirm model when I get home). There is a leak coming from the grey plastic condensate pipe. I'll try and attach a pic. I'm pretty sure the leak is mildly acidic (or really hard water) based on what it did to my hands. The leak does not persist when...
