Have you ever noticed that some radiators in your home heat up quickly while others stay lukewarm? This is a sign that your radiators may need balancing. At Radiator Village, we're not just about supplying efficient and stylish designer radiators, but we can also help you get the best out of them.
Balancing your radiators is a simple DIY job that you only need to do once or twice a year. It improves comfort and reduces wasted energy in your home. Our guide below will walk you through the process step-by-step.
What Does Balancing Radiators Mean?
When your heating system is on, hot water flows from the boiler, through the pipework, and into your radiators. However, radiators closest to the boiler often receive more hot water, while those further away get less.
Balancing controls how much hot water flows through each radiator to ensure all rooms heat evenly—not just the ones near the boiler. Note: balancing is not the same as bleeding. Bleeding removes trapped air, while balancing adjusts the water flow using the lock shield valve.
Signs Your Radiators Need Balancing
-
Some radiators are hot while others stay cold.
-
Your rooms heat up at different speeds.
-
You’re constantly adjusting the thermostat to compensate for lost heat.
-
You’ve recently installed a new radiator or boiler system.
If any of these sound familiar, it’s time to balance your system.
Tools You’ll Need
-
Radiator bleed key
-
Lock shield valve adjuster or adjustable spanner
-
Digital thermometer or infrared temperature gun (optional but helpful)
-
Pen and paper to record temperatures
How to Balance Your Radiators
-
Bleed all radiators before you begin balancing. Ensure every radiator is fully bled so trapped air isn’t affecting flow or temperature.
-
Turn off the heating and allow the system to cool completely—start with a cold system.
-
Open all radiator valves by turning the thermostatic radiator valves and lock shield valves fully open.
-
Turn the heating back on and note the order in which the radiators heat up. Those that get hot first are closest to the boiler; those heating last are furthest.
-
Adjust the lock shield valves. Start with the fastest heating radiator by closing its valve completely, then opening it slightly (about ¼ to ½ turn). Move to the next radiator and open its valve slightly more, continuing this pattern to restrict flow to the fastest heating radiators and allow those further away to heat up.
-
Fine-tune using temperature readings. Check the flow and return pipe temperatures on every radiator. Aim for a 10–12°C difference between them.
When to Consider an Upgrade
If balancing doesn’t improve your heating or you have old vertical radiators, horizontal radiators, or flat designer radiators that never warm properly, it may be time for a replacement.
