How To Fix A Leaking Home Radiator

What are Radiators?

Radiators are essential to regulate heat flow. They are catalysts in the seamless functioning of electronics in your house. Ensuring flow of thermal energy from one medium to another, they contribute to cooling or heating effects generated by electronic devices. Try eastgateradiators to find radiators as per your requirements. They provide a wide range from Designer radiators to standard ones. Choose a radiator according to your needs.

How do Home Radiators work? 

The main type of radiator is the Central Heating Radiator. It’s functioning is easy to understand. A central boiler is the source of a pipe that runs through the connecting individual radiators in the house. 

The hot/cold coolant that passes through the pipe and radiates heat into the air around it is the main stimulant. This inturn helps your electronic device to emit cold/hot air into the room.

There are smaller and several other types of radiators like Electric Radiators, Dual Fuel Radiators and many more that connect to different types of electronic devices in our homes. Some are stimulated by thermal fluid. Electronics like the AC’s, small heaters etc have radiators that regulate the coolness/heat of the house. 

Few other types of Radiators are:

  • Single Panel Radiators
  • Double Panel Radiators
  • Horizontal Radiators
  • Vertical Radiators
  • Column Radiators
  • Heated Towel Rails

However, the choice of radiator depends on its purpose or requirement. The architecture and provision inside the housing structure is also a factor that deciphers the choice of radiator. 

How Do Home Radiator Leakages Happen?

Like any other devices malfunctioning at times, radiators may also cause functional problems. Most common of them all being the leakages. A simple rupture in the pipe that supplies the hot coolant may cause a leakage, thereby causing accumulation of water and floors getting wet. There are various other reasons for leakages like: corrosion of radiator due to extensive and unserviced use, use of weak coolant and many more. 

Radiator leakages happen at 3 places: The valve, the body of the radiator and the pipe that fills water in the radiator. If you are aware of the functioning of your home radiator, it is not difficult to self-fix your home radiator. While a major rupture calls for professional plumbing assistance, for minor ruptures it is possible to fix leakages yourself at home.

  • Soak up water that may still be left in the radiator and may exit once valves are turned off. 
  • Undo the union nut, allow any remaining water to exit via the bleed valve once it is opened. 
  • The most important step is to thoroughly wrap the PTFE tape around the leakage spot. Make sure the tape is wrapped 10-15 times to thoroughly seal the ruptured part of the radiator. 
  • Secure the union nut to close the pipe. Open the bleed valve and the valve at the rear end of the radiator carefully. 
  • Restart the water supply and check if the water leak has been repaired. If there is no water leaking then your job is done.
  • Close the bleed valve. Your radiator is fixed!

Reasons For Radiator Leakages
