Find out ways you can troubleshoot your radiator and when you need to start searching for, “heating, cooling, and plumbing near me” to fix the issue

When the weather cools down, we rely more on our radiator than we do any time of the year. That’s why, when your radiator suddenly stops working and is no longer heating your home, it can get stressful. But, before you start searching for “heating, cooling, and plumbing near me, there are a few ways that you can troubleshoot your radiator from home. Let’s find out why your radiator isn’t working properly, and learn about how you can fix small issues that do not require a professional plumber.

Find Out If Your Other Radiators are Still Working

Before you look for “heating, cooling, and plumbing near me,” you should verify how many radiators in your home are still working.

You can feel if your radiators are functioning properly or are only heating in certain parts.

If you notice that one of your radiators is no longer producing heat, then your first step is to check on the other radiators in your home. If only one radiator is not not working, then the issue is likely within that specific radiator. On the other hand, if two or more of the radiators in your home are not working, the issue could be with your pipes, plumbing, boiler, or thermostat. Once you’ve determined where the problem is coming from, it’s time to move on to the next step.

What to Do If Multiple Radiators in My Home are Not Working

Follow these steps if more than one of the radiators in your home is not working properly. In some cases, you may have to find a heating, cooling and plumbing company near you to fix the problem.

Make sure your heating system is turned on and set to the correct temperature.

The first thing you need to check, though this may sound ridiculous, is that your heating system is actually on. There are many occasions when homeowners panic and begin researching “heating, cooling and plumbing near me” before they realize that their heating has been off this whole time. Once you’ve verified that your heat is, in fact, on, it is time to turn your attention to your boiler and plumbing.

Low Boiler Pressure

Your system’s pressurization plays a big part in heating your home. If the water pressure in your system is too low, heated water will not be able to reach your radiator, meaning no heat will reach your living spaces. You can easily check your water pressure by locating the meter on the front of your boiler. When you inspect your boiler, you should notice that your boiler pressure is between 1 and 2 bar. If your pressure is below 1 bar, you can increase the pressure by turning the top up valve and releasing more water into the system, which increases the pressure.

Diverter Valve Fault

If your pressure is working properly and you are unable to find any other issues, your next step is to investigate your diverter valve. Your diverter valve is a mechanism that controls the flow of water through your home. The valve dictates how much heated water can pass through to either your heating system or your taps. To check on your diverter valve, test your taps to see if you are still getting hot water. If you are still getting hot water through your taps, then your diverter valve is likely stuck. To fix this issue, we recommend that you search, “heating, cooling, and plumbing near me,” to find a skilled professional that can rectify the problem.

What Do I Do If Only One of My Radiators is Not Working?

Do I have to find heating, cooling, and plumbing near me? For some radiator issues, the answer is — “yes”

Radiators, such as a small bathroom radiator can be complicated to fix, which is why you should call a professional for certain issues.

If you’ve discovered that only one of your radiators is no longer working, then you need to take a different approach to troubleshooting. The first thing you need to verify is whether or not you are getting any heat from your radiator. In some cases, radiators will still produce very little heat despite a system issue. If there is no heat coming from your radiator, you should examine your thermostatic radiator valve.

Thermostatic Radiator Valve

Sometimes, depending on the setting of your radiator, your thermostatic valve will seize up and become stuck in the off position — even when you have set it to heat. Luckily, this is one of the easiest ways to get your radiator back up and running again. To get your thermostatic valve working properly, remove the top of the and check to see if the middle pin is moveable. If the pin is unable to move up and down, simply tap the pin to free it up.

Air Pockets

Noticing that your radiator is producing some heat, but only from the bottom? Then, there is a good chance that there is an air pocket inside of your radiator. When there are air pockets inside of your radiator, the air takes up space meant for heated water that causes cool gaps at the top of your radiator. To correct this issue, you need to bleed your radiator of the air inside to get it working properly again. First, you need to find your radiator key and unscrew the bleed screw until you can hear air hissing out of the radiator. Then once water appears, you can tighten the bleed screw again and your radiator should resume normal operation.


Over time, as water flows through your radiator, sludge will naturally accumulate. If too much sludge accumulates in your radiator, it will cause blockages and only part of your radiator will be able to heat properly. Clearing your radiator is a difficult task, so we recommend that you find a professional to remedy the situation.


If you are having trouble with your radiator and are searching for “heating, cooling, and plumbing near me,” then you’re on the right track. Always call a professional if you feel uncomfortable working with your radiator and boiler system.
