When it comes to looking after your radiators, there are some steps you can take well before autumn truly sets in to keep them efficient and lasting for years.

When the temperatures drop, you want your heating to work properly to keep your home warm. One step you can take is to balance your radiators whenever you check your boiler and central heating for any potential cold spots.

Trads is here to explain not only why you should balance your radiators but we’ll explain how you should balance them so your heating is ready for winter. Read on to find out more...

Caring for Your Radiators

Radiators are very reliable and can last for decades, providing consistent and comfortable heating. Radiator maintenance doesn’t take long but it’s important to make sure your system is running efficiently. After all, they are just one part of a larger central heating system.

Radiators are fairly easy to care for, requiring some basic seasonal maintenance to keep them running for years. It’s always best to do your maintenance in the summer or early autumn for a number of reasons. Firstly, so you can see what is and isn’t working well before you need it. Secondly, because plumbers are often more available at this time of year.

Why is my radiator cold?

There are few things nicer in autumn and winter than having a warm home to wake up in or come back to when the weather is cold.

However, if you’ve found that your radiators stay cold, you may need some help. Besides just leaving you cold and shivering, radiators that fail to heat up can also indicate larger problems. These can include debris in the system causing blockages or a poor system set up.

A radiator may be cold for a number of reasons, but there are also some fixes. We’ve highlighted the main areas below:

Boiler

Check your heating to make sure that it is on the right setting and working properly. If you have a combi-boiler, check that it’s set for hot water and heating and not in a ‘summer mode’, if you have one. You should make sure there is no fault code displayed on your boiler as this may be more complicated to deal with.

Pump

If your heating system has a heat pump, ensure it’s working. If the pump has stopped working, it won’t heat the water needed to keep your radiators warm. This will result in all of your radiators losing their temperature. The easiest way to check if your heat pump is working properly is to see if it’s making any noise.

Air in the system

If one or more radiators in your home are cold, this may mean there is air in the system. Air in a radiator tends to gather at higher points - like the top of the radiator - and prevents water from being distributed evenly.

Valves are stuck

A cold radiator can be caused by a stuck valve. This will often be the case if you have an issue with just one radiator. The thermostatic valve, the white one that controls water flow, can become seized due to age or even a lack of use.

Water pressure

If your boiler and pump are working normally, your water pressure may be the fault. For a residential gas boiler, 1.0 bar will often be the correct pressure, but always check your manufacturer’s instructions. The pressure level will be shown on the gauge and you may need to balance your system to fix it.

Why balance radiators?

Simply, unbalanced radiators won’t heat up at the same speed as each other, leaving some areas of your home colder than others. It can become quite an issue when it gets to cold winter nights. It can also mean putting extra stress on your boiler by trying to get warmth into a room that is cold because the radiator is unbalanced.

Balancing radiators means matching the speed radiators take to heat up across all of the rooms in your home. It’s simple but very important.

What is the difference between balancing and bleeding your radiators?

Balancing a radiator is entirely different both in terms of process and purpose to bleeding a radiator. Bleeding a radiator is done to a single radiator which is not heating up evenly or at all because air has become trapped inside.

How to balance your radiators

  1. Turn off your heating: To begin balancing radiators, they must be completely cold so turn your home heating system off.
  2. Work with your radiator valves: Balancing your radiators involves having lockshield valve access. So, you need to get that valve cap removed.
  3. Open the radiator valves: Once your valves are exposed, open them up in an anti-clockwise, left direction. Depending on the age of your radiators, this may be difficult.
  4. Turn your heating up: With your radiator valves now open, switch your heating back on and turn it up. Then, make note of the speed at which each of your radiators takes to warm up. Radiators nearest to the boiler will often be the fastest.
  5. Measurements: Measure each of your radiators and how quickly they heat up.
  6. Turn off your heating again: Turn your central heating off again and let your radiators go cold.
  7. Fastest heating radiator: Now, turn the heating back on and go to the radiator that was previously quickest to warm up. Close its lockshield valve in a clockwise direction. Then, open it by one-quarter turn.
  8. Temperature measurements: Still at the fastest radiator, which is now warm, take a couple of temperature readings. Do this using a digital thermometer. You’ll need readings from:
    1. The pipework next to the valve.
    2. The pipework on the opposite side by your thermostatic valve. Then, record the difference.
  9. Open the lockshield: Open your lockshield valve until the temperature difference between the two points is 12°C. That’s how balancing your radiators works.
  10. Do the rest: Once you’ve balanced your first radiator, repeat this for your remaining radiators. Always do so in the order they took to warm up. For the radiator that was slowest, you may need to open the lockshield valve completely.
