When your radiators are not working you have two options: bleeding your radiators or balancing them. Bleeding your radiators is good for when a single radiator in your home has cold spots, or it doesn’t fully heat up, but balancing them is the right thing to do if one or more of your radiators doesn’t heat up at all when the heating is on. If you need to bleed your radiator, then you can find a simple step-by-step guide here. It’s also recommended that you bleed your radiators before balancing your system, as you’ll get a more accurate temperature reading from them. What you’ll need When you balance radiators, you allow more water to flow to the colder radiators and restrict the flow from the radiators that are too hot. If your radiators are not balanced, it will be harder to achieve the desired temperature if they are already on. Uneven room temperatures, varying heating times, and having to adjust thermostatic radiator valves frequently can indicate that your radiators need balancing. Why is the temperature difference set to 12 degrees during radiator balancing? Misuse of Thermostatic Radiator Valves (TRVs) If TRVs have been fitted to radiators around your home, and not adjusted correctly, this can lead to system-balancing issues.

If your radiators are cold at the bottom, this could be caused by sludge and debris in your system simply preventing water from flowing correctly inside your pipes and radiators. In this instance you will need to flush your central heating system. You can learn all about this in our blog post: Flushing Radiators Explained.Starting from the radiator furthest from the heating source if you have a combi boiler, or furthest from the water pump (usually found in the airing cupboard next to the hot water cylinder) if you have a heat-only boiler, turn all thermostats to 2. When it comes to home maintenance and DIY it is possible to hire a professional to take care of all the work for you, which is especially useful if you don’t mind the expense or the time to learn a new skill. However, for many people carrying out basic maintenance around the home will save money and it can also be quite good fun to learn a new skill. With this in mind, one of the tasks that can be done by most people with a bit of guidance and a few simple tools for balancing the radiators. Balancing is about making sure the radiators emit a steady and consistent heat across the entire home. Whereas, bleeding is used to identify and fix the problem of a single radiator that is heating up slowly due to trapped air in the system. By bleeding, you let the air out hence preventing cold spots on your radiator.

This isn’t very accurate, but I did this for a few years when I started out, before buying a laser thermometer.eezytiger - I have four of those temperature sensors fairly recently - possibly from an earlier link of yours. You close the first radiator’s valve and then open it gradually until you have reached the desired temperature. You’ll need to wait for them all to cool down again before starting the balancing process. This is because you want to get an accurate temperature read on your rads as you balance them. 6. Turn the heating on, again
