Even though forced air heating is more prevalent in residences, radiant heating systems are still the most popular choice for heating homes in the US.
Radiators are a reliable and comfortable method of heating, despite the fact that some people find them to be archaic. Radiators are a cost-effective alternative to warm-air heating systems because they do not provide the same type of dry heat and have a longer lifespan. Radiator maintenance is simple, but it is essential to ensure that you perform each step correctly in order to maintain your system operating at peak performance.
Are you prepared to find out how to properly maintain your radiator system? Continue reading to find out which of the responsibilities you are capable of doing on your own and which are better left to a professional.
How the Components of Radiators Work
The energy behind radiant heat comes from boiling water. The water in a closed system that consists of a boiler and connected pipes is heated to over 87 degrees Celsius by the boiler. This water is circulated through the system. strategically placed radiators located around the building and are supplied with hot water by a pump. These radiators then heat the air in the surrounding area.
When it has reached the desired temperature, the water is poured back into the boiler. This closed system recycles water on a continuous basis by bringing it back around to be heated once more. This indicates that you have an effective system that consumes a small amount of the available utilities.
Radiant heat has several advantages, one of the most notable of which is that it is beneficial to the atmosphere of your home. Although forced air systems may be more powerful, the air in your immediate environment becomes drier as a side effect, and they also circulate dust and particulate throughout your house. Radiant heat has the additional benefit of being more consistent.
Cast iron is frequently used to construct older radiators because of its high density and ability to keep the heat for an extended period of time. Steel, which is used in the construction of modern radiators, is a material that is both lighter and less expensive.
Radiator Maintenance
Radiator systems are quite simple to maintain; all that is required is some standard seasonal upkeep in order to keep them operational for many years to come. If you want to ensure that your closed system is operating effectively, please be sure to follow these steps:
Adjust the Radiator’s Bleeding
Even though a boiler and the pipes that are linked to it form a closed system, there is still the possibility that air could get out of the water as time goes on. Because air is less dense than water, it is able to float upward through the radiators, which results in the formation of air pockets. It is essential that you bleed this excess air from the system as part of the seasonal maintenance that you perform.
The first thing you need to do is switch off the system and give the water some time to cool down. Alternately, you might undertake this maintenance only a little time before the weather starts to become cooler before you’ve even switched it on for the first time.
A little valve should be located towards the top of each of your radiators. They might have a specialized key to turn them, or they might be able to be rotated manually. While you spin your valve in the counterclockwise direction and keep a bowl under the opening below the bleed, listen for a hissing sound as air escapes.
When the valve is turned, the pressured system will cause the air to be forced out. Keep the valve open until water begins to flow, at which point you can close it by twisting the key counterclockwise on the valve. It is not caused panic if the water in the lines appears cloudy or unclean as this is quite normal.
Be Sure to Check the Boiler Pressure
After removing all of the air from the system, the next step is to examine the pressure inside the boiler. If you open the service panel on the boiler, you should be able to find a temperature and pressure gauge there. Depending on the manufacturer, the pressure gauge on a cold boiler should read 1.3 bar, and the pressure gauge on a hot boiler should read 1.5-1.8 bar.
In the event that your boiler’s pressure falls within these parameters, you will likely need to add more water to the system. You can open a cold water line that runs into your boiler in order to allow additional water in, but you should do so while keeping a close eye on the pressure gauge. This may cause your boiler to explode. When the gauge reaches 1.3 bar, turn off the valve that controls the cold water.
In the event that you inadvertently raise the pressure above 1.3 bar, the system will feature a pressure relief valve for you to use. Be aware that this valve will expel water in order to maintain the system’s equilibrium, and position a large bucket underneath it to capture any water that may run out as a result of the valve’s operation. If the gauges on your instrument are reading too high from the start, you can use this valve to let some water out of the system.
Performing Maintenance on the Combustion Chamber
Your water is heated by fire that is supplied by a combustion chamber, which is part of your boiler’s power source. It is possible that the chamber will not function properly if it accumulates an excessive amount of residue. Because there is a risk of fire when cleaning out the chamber, it is recommended that you have a trained professional maintain this component of your system at least once every few years.
Keep Yourself Safe Warm
With the help of these guidelines, you will have a better understanding of the maintenance that can be performed on your radiator on an annual basis to ensure that your system continues to function well. A system that has been properly maintained can last for decades with relatively little effort.
Always take caution while dealing with your radiator system, and before doing any of these maintenance procedures, be sure the water has cooled down and is safe to drink. Even while radiators are quite risk-free, performing maintenance on a hot boiler might expose the worker to severe burns from water or steam that is extremely hot.
