Why Do Panel Heaters Crack?

Panel heaters are a great way to stay warm in the winter and cool in the summer. They do have their downsides, though: they can be expensive to run, they only work well in certain climates, and if you don’t take care of them properly they can crack or break down. But why do panel heaters crack? And what can you do about it? In this article we’ll look at some of the most common reasons for cracks in panel heaters, including how often you should replace your pads or even replace your heater altogether!

What Are Panel Heaters?

Panel heaters are a type of heater that are installed in the walls of a building. They come in many shapes and sizes but generally consist of an aluminium backplate, glass and a heating element. A number of different designs are available: some have no visible elements while others look like traditional radiators.

All panel heaters work by using convection currents to create warmth within the room. There is no combustion involved so they do not give off any smoke or fumes which makes them very safe to use indoors. This means that they can be installed directly on walls or ceilings without having to worry about fire safety regulations too much – although it’s important always check with your local council before installing one yourself!

Why Do Panel Heaters Crack?

Panel heaters are made of plastic and therefore are prone to cracking. They’re also designed to be mounted on a wall, which means they can crack if they aren’t mounted correctly. Finally, panel heaters can crack if they’re dropped or mishandled.

If you’ve ever owned a panel heater that’s cracked and been baffled by the cause of it, you’re not alone! To help you understand why this happens so often—and how to avoid it—we’ve put together this list of potential causes for cracks in your heater:

  • Panel heaters are typically made of plastic, which makes them more fragile than other types of space heaters (read: metal). Plastic is also less resistant than metal to heavy wear-and-tear or impact damage from dropping or mishandling the device.
  • Since these units are designed for mounting on walls with brackets attached at the top and bottom corners, any kind of damage sustained by either bracket will usually result in cracking along those lines as well (see above).

How Often Should I Change The Pads In My Panel Heater?

If you use your panel heater regularly, the pads should be replaced every year or so. If you don’t use it as often, they can last longer than this. You’ll know when a pad is worn out because it will no longer heat up as well as it used to and may cause the surface of the panel to get hot enough for burns. If your panel heater has cracked due to pad wear, change all of its pads at once so that you’re not replacing just one at a time over time—this will keep things running smoothly and prevent any more damage from happening!

Should I Replace My Panel Heater If It Cracks?

If a panel heater cracks due to an outside force, you don’t need to replace it. This can happen if the pad shifts and exposes the frame of your heater. In that case, remove and replace only the pad.

If a crack appears on your panel heater for no apparent reason and you notice that it’s not in contact with any other surface (such as another object or person), then there’s a good chance it’s just cosmetic damage caused by improper installation or age. You may want to consider upgrading to a new model that has better quality control processes in place so this won’t happen again!

You need to look carefully at what is causing the cracks and replace your panel heater only if the crack is caused by the heater itself and not an outside force.

When you find that your panel heater has cracked, check to see whether it is caused by an outside force or the heater itself. If it is caused by an outside force, look at the source of the force and repair it. If not, you need to replace your panel heater only if the crack was caused by an internal fault with your unit.


If you have a cracked panel heater, it is important to know the cause and whether or not you should replace the unit. If your heater is cracking due to an outside force, then you should replace it immediately so that it does not continue to crack further down the line. If your heater cracks because of wear and tear (for example, if it is being used constantly), then this can be considered normal wear-and-tear maintenance which requires replacing parts (such as new pads) rather than buying an entirely new unit
