Increase the Performance and Longevity of Radiators

HVAC specialists and plumbers suggest that, on average, radiators should last between 8 and 12 years. Many radiators will stop working or need major repairs within 10 years. Using a poorly functioning radiator will increase your electricity bill because it won’t be able to heat your room efficiently.

Annual service for optimal performance

Radiator Repairing

As a rule, radiator heating systems should be regularly maintained with service at least once per year. Radiator maintenance is similar to servicing a car for a tune up or an oil change. Annual radiator check-ups will ensure that the system is functioning optimally. Regular radiator maintenance will improve performance and help you save money on heating bills.

Understanding the functionality of cast iron radiators will help to you maintain your radiator’s performance and identify when it needs to be serviced. With our simple tricks and tips below, you can increase the performance level and life of your radiators.


Give radiators room to breathe

Homeowners typically invest money in heavy cast iron radiators because of their quality, construction and durability. To try to save space, many people install radiators in cluttered, congested, and awkward spaces. However, this impacts their ability to function at their highest level. To maintain your radiator’s working ability for an extended period of time, it must have space to breathe.

  • Hiding electric radiators by placing them behind cabinets, shelves, dressers, and chairs will prevent them from functioning properly, and should be avoided if possible.
  • Blocked radiators will cause your room to be filled with restricted, hot airflow. 
  • Keep the spaces surrounding the radiator free from clutter to allow the heated air to flow smoothly into every room.

Check for stray currents

This major maintenance tip for electric radiators can be easily overlooked. If you are installing a new radiator and have completed electrical work beforehand, ensure that the electrical lines are working properly.

  • Stray currents may result in corrosion and cause your radiator to stop functioning.
  • Routinely check the radiator’s condition by using a voltmeter between the ground and coolant. Make sure not to touch the filler neck or the metal core.
  • A reading of .05 Volts or higher indicates that you have a damaging current. To solve the issue, turn the accessory one at a time to identify the faulty area.

Keep radiators away from curtains

Hot water radiators should be kept away from floor- and mid-length curtains and draperies.

  • Radiators are often located near windows, which means they are often close to curtains and draperies.
  • Covering or hiding radiators with curtains restricts airflow and is a potential fire hazard.
  • The areas surrounding the radiator should be clear and clutter-free.
  • Blocking the radiator with curtains or drapes can reduce its efficiency and increase electricity bills.

Pipework restricted position

Finding the ideal position for your radiator can be challenging, but your pipework will determine where the radiator can be placed. Traditionally, radiators were installed in the coolest part of the room, often under a window or along an exterior wall. With modern installation, it may make more sense to move your steel or cast iron radiator away from the wall to a more central position. This can help free up space and give your room a fresh new look.

These simple tricks and tips will help keep your radiator running at optimal levels for longer. For adjustments to your existing radiators or for information about new installations, contact Just Rads today!
