Seasonal Radiator Maintenance Tips You Need To Know

Seasonal Radiator Maintenance Tips You Need To Know

Even though forced air heating is increasingly prevalent in American residences, the majority of people living in the United Kingdom still rely on radiant heating systems to keep their homes warm.


Radiators are excellent sources of heat that are reliable and comfortable, despite the fact that some people find them to be archaic. Radiators keep interiors warm without producing the dry heat that is typical of warm air heating, and the systems themselves are incredibly durable. The level of maintenance required for radiators is low, but it is essential to ensure that the job is done right in order to maintain your system operating at peak performance.


Are you prepared to acquire the knowledge necessary to properly maintain your radiator system? Continue reading to learn what responsibilities you can handle on your own and which ones are better left to a trained expert.

How Radiators Carry Out Their Duties

The source of radiant heat is boiling water. A closed system including a boiler and connected pipes is loaded with water, which is then heated by the boiler to an internal temperature of more than 87 degrees Celsius. The heated water is circulated by a pump through the network of pipes and into the strategically placed radiators, which then heat the air in the surrounding area.


After it has had a chance to cool down, the water is poured back into the boiler. This closed system continually recycles water by causing it to go through the heating process over and again. This indicates that you have a system that is effective and consumes a low amount of utilities.


Radiant heat has many advantages, one of the most significant beings that it is healthier for the atmosphere inside your home. Forced air systems may be more powerful, but they also cause the air around you to dry up and they circulate dust and particulate matter around your home. Radiant heat also has the potential to be more consistent.


Cast iron is usually used in the construction of older radiators due to its ability to hold heat for an extended period of time despite its heavy weight. Steel, which is used in more modern radiators and is lighter and less expensive than other materials, is one example.

Radiator Maintenance

Radiator systems are quite simple to maintain; all that is required to keep them operational for many years to come is some fundamental seasonal upkeep. Make sure your closed system is operating effectively by adhering to the following steps:

Do Not Bleed the Radiator

Even though a boiler and all of the pipes that are linked to it form a closed system, there is still a possibility that air could be leaking out of the water over time. Because air is less dense than water, it is able to float to the top of the radiators, where it forms pockets of air. It is imperative that you bleed this excess air out of the system as a component of the seasonal maintenance that you perform.


The very first thing you need to do is power down the machine and give the water some time to chill. Alternatively, you could undertake this maintenance right before the weather starts to get cooler before you’ve even switched it on for the first time.


Your radiators should each have a little valve located at the top of the unit. They might come with a specialized key, or they might be able to be turned by hand. Rotate your valve in the counterclockwise direction while holding a bowl under the opening below the bleed. Listen for a hiss as air escapes as you make the turn.


The pressurized system will drive air out of the opening when you turn the valve. After allowing water to flow freely through the valve for some time, turn the valve key counterclockwise to close the valve. It is very usual for the water in the pipes to appear muddy or unclean, so there is no need to be frightened about this.

Examine the Pressure in the Boiler

Checking the pressure in the boiler is the next step to take once the air has been evacuated from the system. You will need to open the service panel on the boiler in order to locate the temperature and pressure gauges. The pressure gauge on a cold boiler should read 1.3 bar, depending on the manufacturer, and the pressure gauge on a hot boiler should read 1.5-1.8 bar.


If your boiler’s pressure is lower than the guidelines for acceptable levels, you may need to add extra water to the system. You can open a cold water line that runs into your boiler in order to allow more water in; however, you should do so while carefully monitoring the pressure gauge. As soon as the gauge reaches 1.3 bar, turn off the valve for the cold water supply.


Your system will include a pressure release valve in it just in case you happen to mistakenly bring the pressure above 1.3 bar. Be careful that this valve will release water in order to maintain the system’s equilibrium; as a result, you should position a large bucket underneath it to catch any water that may run out. If your gauges are reading too high from the beginning, you can also use this valve to discharge water from the system.

Regular Upkeep of the Combustion Chamber

The combustion chamber of your boiler is the source of the fire that is used to heat the water in your boiler. It’s possible that the chamber won’t function properly if it builds up too much residue. Due to the high risk of starting a fire when cleaning out the chamber, it is recommended that you have a trained professional maintain this component of your system once every few years.

Be Sure to Keep Warm and Safe

With the help of these guidelines, you will have a better understanding of what radiator maintenance you can perform each year to maintain your system operating at peak performance. A properly maintained system can last for decades with very little effort on the user’s part.


Always exercise caution when working on your radiator system, and make sure the water has cooled down and is safe to drink before doing any of these maintenance procedures. Even while radiators are extremely risk-free, any work done on a hot boiler during maintenance poses a significant risk of severe burns from hot water or steam.
