How To Balance Radiators

Let’s get straight into the step-by-step process of how to balance radiators. Cold spots, be gone!

Step 1: Turn Off Your Heating

Right, turn off your central heating system first. You must ensure all radiators are completely cold before you begin balancing.

Step 2: Open All Your Radiator Valves

Next, open all the radiator valves in your home. This involves turning the valves anti-clockwise. Thermostatic valves can be easily opened by hand.

There may be a plastic cover on the lockshield valves. Remove these with an adjustable spanner or lockshield valve key.

Step 3: Turn Your Heating Back On

Now all your radiator valves are open, it’s time to turn your heating back on. Pay attention to the order in which your radiators heat up. Typically, radiators closest to your boiler will heat up first.

Step 4: Allow Your Heating to Cool Down

Now all your radiators have heated up, turn your heating off again and allow it to cool down completely. This process will take a while, and it might be sensible to leave this overnight if it can wait that long.

Step 5: Adjust the Fastest Heating Radiator

Now your heating has cooled down, turn your heating back on and locate the radiator that heated the fastest in step 3. Close the lockshield valve on this radiator completely, then open it by a quarter of a turn.

Step 6: Measure the Temperature

Grab your digital thermometer or multimeter. Measure the temperature of the pipework next to the lockshield valve. Then, measure the temperature of the pipework on the opposite side of the radiator. The goal is to achieve a 12°C difference between these two readings.

Step 7: Repeat for Other Radiators

You aim to achieve a 12°C difference in temperature for the first radiator. Once done, repeat steps 5 to 6 on all other radiators in your home, starting with the next fastest heating radiator. Open the lockshield valve more on radiators further away from the boiler.

Follow this process on all your radiators. You will notice the difference in warmth consistency absolutely staggering, trust me!

How Do You Identify When Radiators Need Balancing

There are several signs that your radiators may need balancing in your home; this could be any of the following [1]:

  • Certain rooms in your home heat up faster than others.
  • Some rooms reach the desired temperature slower than others.
  • There are significant temperature variations between different rooms. One could be too hot, while the other is quite cool.
  • You continually need to adjust your thermostat to maintain a comfortable temperature.

If you notice these signs, that is a good indication that you need to balance your radiators.

Understanding Radiator Valves

Each radiator has two types of valves – a thermostatic radiator valve (TRV) and a lockshield valve.

  • Thermostatic Radiator Valve (TRV)[2]: This is a manual valve, usually located on one side of the radiator. It allows you to control the temperature of that individual radiator. 
  • Lockshield Valve[3]: This valve is located on the opposite side of the radiator to the TRV. It controls the hot water that enters the radiator from your boiler.

Why Do You Need To Know How To Balance Radiators?

What is radiator balancing, and why should you learn how to do it? It’s super important to maintain your heating; read on to find out more!

Radiator Balancing: What Does It Mean?

Radiator balancing is adjusting the water flow through each radiator in your home.

This ensures that all radiators heat up simultaneously. The aim is to get them heating at the same pace, leading to your heating performing as efficiently as possible.

Why Is Balancing Radiators Important?

Learning how to balance radiators helps prevent certain rooms from becoming too hot.

In contrast, others remain cold and merciful to the elements. Balancing radiators means even heat distribution throughout your home.

This ensures your family bathroom isn’t roasting hot while your living room is like the Antarctic.

Understand Your Heating System

You must understand how your heating system works off the bat. Here’s a simplified explanation:

When you switch on your heating, hot water is pumped from your boiler.

This hot water will go towards heating your radiators or be directed towards your hot water tank for use in showers or your kitchen taps.

If your radiators aren’t balanced, the ones closest to the boiler will perform well.

The other one in the man cave on the third floor will start gathering icicles, though.

Post-Balancing Tips

Your home should heat more evenly once you’ve balanced all your radiators.

However, remember that balancing your radiators is not a one-time job.

It’s good practice to check the balance of your radiators every year, especially before the dreaded winter season.

How To Balance Radiators FAQ

Can an Unbalanced Heating System Cause Radiators to Stay Cold?

Yes, an unbalanced heating system can cause some radiators to remain cold. This is because the hot boiler water may not reach these radiators efficiently.

What’s the Difference Between Bleeding and Balancing Radiators?

Bleeding a radiator releases trapped air, preventing the radiator from heating up correctly.

Balancing a radiator involves adjusting the flow of hot water, allowing all radiators to heat up evenly.

Is Balancing Radiators a DIY Task?

You can balance your radiators with the right tools and a little patience. However, hiring a professional might be a good idea if you need more clarification or are uncomfortable doing it yourself.

How Do I Know If My Radiators Are Balanced?

To verify proper radiator balance, assess the temperature by following these steps.

  • Utilise a thermometer to measure the temperature at the pipework close to the lockshield valve.
  • Measure the temperature at the pipework near the radiator’s opposite end near the thermostatic valve.
  • Attempt to achieve a 12°C difference between these two readings.

The Bottom Line

Learning how to balance radiators is a task to ensure your home heats up evenly and efficiently. While it may seem complex initially, this guide will give you the confidence to ensure your radiators perform optimally.

Seeking Professional Help

If you have followed the steps in this guide and still need assistance with your radiators. It might be the right time to seek professional help.
