Locate your external filling hose. It is usually close to the boiler, but it can sometimes sit under the kitchen sink or in the airing cupboard.

While there may be an upfront cost to TRVs, as they help reduce the amount of Gas or Electricity required for your central heating system and given the way you are charged for energy depends on how much is used, you also reduce the cost of ongoing heating bills. Another way to look at this is, eventually your TRVs pay for themselves and provide a long-term cost saving compared to just having manual valves. It is one of the reasons why it is a common improvement listed on Energy Performance Certificates within homes. Angled and corner valves are interchangeable, but have slightly different designs. If your pipes turn at an angle of 90 degrees to enter the radiator, you'll need angled valves. These are the most common type of radiator valve and are popular in many homes. Corner ValvesIf your radiator’s hot at the top and cold at the bottom, it doesn’t need bleeding. But if it’s hot at the bottom and cold at the top, that’s a sure sign that it does. How do I bleed my radiators? The procedure of “ bleeding a radiator” involves getting rid of any extra or trapped air in the system. Since air cannot be heated in the same manner that water can, this is typically the cause of a radiator’s top feeling chilly.

Slot your radiator bleed key into the bleed point of your radiator, holding the tissue just underneath. Radiator valves control the temperature of your radiator by adjusting the flow of hot water into the pipework. Valves always come in pairs: one to adjust the amount of water entering the radiator to adjust temperature and the other to balance your system by affecting the amount of heat exiting the radiator.

Look for a small valve at the top of one end of your radiator. On this valve, there will usually be small square bit which can be turned to adjust the valve. Radiator keys, cheap metal implements designed for opening and closing radiator valves, are available at most hardware stores. Find a radiator key that's the correct size for your valve or, alternatively, search your tool chest for a small wrench or other tool that's the right size to turn the valve. [3] X Research source I have hot-water baseboard heat and I don't think I have any bleeder valves for each floor, at least I haven't found any. Each of my three floors are on separate zones. Are they sometimes installed without the bleeder valves? Do I have to hook up a hose to my boiler for each level to get the air out of the pipes? Thanks.
