How to Measure a Radiator: A Step-by-Step Guide

If you want to replace your radiator, you must know how to measure a radiator to get the ideal size for your home’s plumbing and space. The reasons to replace your radiator can be multiple. But it is essential to know how to measure a radiator accurately.

When you go out to the market to replace your old radiator, the common problem you will face is not finding the same size as your old radiator. That’s why knowing the measurements of your radiators is essential. In this article, we will discuss how to correctly measure your radiator so that it perfectly fits your home and fulfils your needs.

What Are the Reasons For Replacing Your Radiators?

The reason you need to measure your radiators is because you are about to replace them, and the reason behind it could be the following:

1. Rust and corrosion

Over time, rust and corrosion build up in your radiators, disrupting the heating flow around your home. It can cause blockages that are beyond economical repair. It disrupts the heating flow, wastes energy, and costs you more on your energy bills. Although regular maintenance can avoid this problem.

2. Damaged Pipework

If your radiator is old, the pipework may also be old. Old pipework can be rusted and damaged, and leaks within your pipes can cause your boiler to make strange noises. Not only that, but the heat will not be distributed adequately.

3. Losing efficiency

As time passes and your radiator gets older, it loses efficiency due to a lack of maintenance and the buildup of dust. Because of this, the radiator takes longer to heat your home, consuming a lot of energy and wasting it, resulting in higher energy bills.

How do you measure your radiator?

Now that you know why to replace your radiators, it’s time to discuss how radiators are measured.

Radiators measuring guide:

  • Measure the width.
  • Measure the height.
  • Measure the pipe centres.
  • Measure the wall-to-pipe centres.

Let’s break them down one by one.

Step 1: Measure the width

Measure Your Radiator Width

To measure the width, you must arrange a measuring tape and a helping hand if your radiator is too broad. Place the measuring tape at the radiator’s left edge, move it across to the right’s farthest point, and note the measurements in millimetres.

Step 2: Measure the height

Measure Your Radiator Height

Measuring the height of your radiator is also a relatively simple process. To do that, you will again need a measuring tape. Place it at the bottom of your radiator, stretch it at the top, and then note the measurements in millimetres.

Step 3: Measure the pipe centres

Measure Your Radiator Pipe Centres

Measuring the pipe centres of your radiators is crucial to determining the distance between the two pipe inlets on your radiators. This measurement is essential while replacing your radiator, as you can buy a radiator with the exact centre pipe measurement. Attach a measuring tape to the left pipe inlet to measure the pipe centre, carry it across to the suitable pipe, and note down the measurements.

Step 4: Measure wall to pipe centres

Measure Your Radiator Wall to Pipe Centres

This measurement is the distance between your radiator pipe’s inlet and the wall to which it is attached. To measure wall-to-pipe centres, take a measuring tape, attach it to the left or right pipe inlet, carry it to the wall, and note down the measurements. The measurement figure will provide an estimate of how far from the wall your radiator is attached. So, when you replace your radiator, you will know how far from the wall it should be attached.

Additional Measurements Suggestion

The above measurements are necessary before replacing your radiators. However, there are a few additional measurements that you might want to consider.

  • Distance between your walls and radiators

Measuring the distance between your walls and radiators tells you how much space you have behind the radiator. To measure the distance, you will need a measuring tape that you will have to attach either to the top of the radiator or the side of the radiator, carry it across to the wall, and then note down the measurements.

  • Distance between the wall and the face of the radiators

Wall-to-wall distance helps you determine how much space your radiator takes up in a room. It is vital to the measurements if you are running short of space. To measure the distance from wall to wall, you will need a measuring tape. Attach it to the radiator’s front face from the top, carry it across to the wall, and note down the measurements.

Conclusion

After reading this article, you can replace your radiators with a new one of an accurate size by following the measurement tips mentioned above. The above measurements regarding radiator sizing will help you avoid problems related to fitting the radiator and managing the space.
