Everything You Need to Know About Radiators

Radiators are one of those things that we all use but don’t really think about until they need repairing or replacing!  But, they are a crucial part of any home heating system and essential to keep us warm and snug in our homes. 

In this post, we’ll explain everything you need to know about radiators, from how they work to how to maintain them.

How Do Radiators Work?

It’s possible to categorize heating systems as passive or aggressive. Forced-air systems employ a more aggressive strategy, directing hot air through a duct system with the help of fans. Radiators, however, are inactive participants in heating systems that heat a house using a piping system and the principles of thermal expansion.

In order to warm the air around them, radiators extract heat from water or steam. They can efficiently be utilized to heat a room by doing this. Metal is used in their construction because it is a superior heat conductor. The radiator’s outside fins gradually warm up when hot water or steam passes through it. The air around those fins warms up along with them.

Radiators essentially move a warm substance through pipes. The pipes turn into radiant heating components after this substance distributes its thermal energy to that conductive material. The substance is brought back to the initial heating source after cooling down to be warmed up once more.

But not all radiators need fluids to function. Particularly contemporary radiators come equipped with cutting-edge features that set them apart from their more conventional counterparts.

Radiator Maintenance

Bleeding Your Radiators

The term “bleeding your radiator” is frequently used when it comes to home improvements, but do you really know what it means, why you need to do it, and how frequently?

Simply said, bleeding is the process of releasing trapped air from the radiator. This air slowly accumulates over time and stops your radiator from operating at all, let alone to its full potential.

Every time freshwater passes through the boiler, a small amount of air enters through the central heating system, contributing to the air buildup. The air then gathers at the top of the radiator, preventing it from filling with hot water and so limiting its ability to heat fully.

To make sure you’re getting the most out of your radiator, you should bleed it at least once a year. Always call a professional plumber if you experience any troubles or complications.

Flushing Your Radiators

Radiator flushing is a little trickier than radiator bleeding. Professionals perform a thorough cleaning of the radiator during this procedure, removing all gunk that has accumulated over time. You might think about having assistance with this process because your rooms can feel warmer afterward.

As was already said, it is typically performed by specialists and can be expensive, costing anything from 200 to 300 pounds. If you do decide to move forward with the process, you can purchase a cleaning system to help stop this issue and prevent further build-up.

When Should You Get A New Radiator?

It can be worthwhile to consider a new larger radiator if you have a large space and must operate a smaller radiator at a greater heat to fulfill your needs. Because they may operate at a lower temperature and still effectively heat the space, larger radiators are more efficient.

You may need to replace the outdated radiators if any of your older radiators can’t manage the output from a new boiler. If you think it’s time for an upgrade, there are many stores that sell and have a wide selection of excellent and dependable radiators.

What Type Of Radiator Should I Get?

Your budget and preferred design will both have an impact on the kind of radiator you choose. Radiators come in a wide variety of styles, including vertical, horizontal, flat-panel, designer, low level, and many more.

Additionally, there are also a variety of radiator types—like hot water radiators, steam radiators, fan-assisted heat exchanger, underfloor radiators, skirting board heating, electric baseboard, and portable radiators. However, there are three primary categories of convector radiators in terms of functionality:

  • Single Panel Convector Radiators 
  • Double Panel Convector Radiators
  • Double Panel Double Convector Radiators

A panel is one of those long, parallel-to-the-wall pieces of metal that stores the hot water from the central heating system and radiates heat throughout the space. Therefore, it should go without saying that the amount of heat produced increases with panel size and number.

The convectors, which are the fins welded to the panels, are utilized to expand the radiator’s surface area and distribute heat more evenly throughout the space.

These are significant factors to take into account, but in order to guarantee that you acquire the right size of radiator, it’s crucial to calculate the heating requirements you desire for the room before you go out hunting for a new radiator.

Where Is The Best Place To Put A Radiator?

Because they are typically the coldest parts of the room, placing your radiator under windows will ensure that the temperature is consistent throughout the space.

There may be certain problems, such as the window blocking some of the radiator’s heat and reducing its efficiency. Heat loss can be reduced by employing materials like Radflek and installing a radiator shelf above it.

Any location of the room where you might need the most heat will be adequate if you choose not to place it near the window.


There is a lot to discuss when it comes to radiators, but the important details are all available to you right now. After reading this, hopefully you will be able to identify problems with and make adjustments to your radiators, giving you and your family a warm and comfortable winter.
