Product Information

The most common plumbing tool that gets called a radiator spanner is a large hex or Allen key type for fitting and removing radiator valve tails. The problem with this is different tail brands (although the same type of tails) have different sized nuts. So, you’ll need a 16mm, 17mm, and 18mm ratchet spanner to cover them all. Radiator drain valves have a square head and are needed to drain radiators and central heating systems. My ratchet radiator drain valve key

Increasingly common on modern radiators in new-build homes or those with upgraded heating systems, TRVs tend to be used instead of manual twist valves. They can be identified by a twistable chunky cap that usually contain a series of numbers from 0 - 5. Each number correlates to a certain temperature with 1 being the coldest and 5 being the hottest. Setting the valve to 0 means the valve is completely off (or closed) and the frost setting can be used to stop your pipes from freezing if you're away during cold weather. Make sure it’s completely turned off, and wait for the radiators to cool down. 3. List all the radiators in your homeWhen you turn your central heating system on for the first time, all your radiators should heat up to the same temperature at the same speed. If they don’t, and you find some are cooler than others, you might need to balance your radiators. Yes, that means, you will have to turn the whole system off again and then repeat the fun bit in Step 4 to make sure all of your radiators are heating up at the same rate. Generally located on the flow pipe, a manual or twist valve can be identified by a cap that is very easy to twist by hand. It also might have a double-ended arrow on the top of the cap with + and - minus signs, indicating how open or closed the valve is. The more open the valve is, the more hot water will be able to flow into the radiator each time you turn your central heating system on.

A radiator Allen key (or hex key) is a large Allen key used for fitting and removing certain types of radiator valve tails.

This type of valve is smaller, and covered with a domed plastic hood. Some have a screw through the hood that must be taken out before you can take off the plastic hood. You’ll need pliers or a grip of some kind to take off the hood. Underneath looks like the end of a flat-head screwdriver. When you have a radiator hot at the bottom and cold at the top then you will need to bleed the air out to get it fully heated again. The best way to do this is use a radiator bleed key, sometimes called a radiator vent key. Best Radiator Bleed Key Quite simply, your radiators are out of balance. Balancing is the technique of regulating the water flow to ensure that your radiators all heat up at the same time and to the same temperature. Radiator Bleed Valve: Not really a valve but they do get called this. There are different types of radiator bleed valves and they are for bleeding radiators.

TIP: It’s vital that you leave a few minutes after each adjustment of the radiator valves to allow the temperature to change. 9. Repeat with the other radiators Once you’ve rebalanced every radiator in your home, hot water from your boiler will reach them at equal speed and your house should warm up at the same time. What to Do if Balancing Radiators Doesn’t Solve the Problem? Some radiator valves do not get opened or closed for years, which can cause them to leak when closing for the first time.We need to do this so that we have an unrestricted flow of water going through our system so that we are able to measure which radiators are heating up the fastest. Balancing your radiator, on the other hand, means you’ll need to allow more hot water to flow to the colder radiators – and out of the ones that are too hot.
