In winter - but not only! - the wall-mounted fan heater is able to transfer important advantages in terms of environmental comfort.

But what are the characteristics of a wall-mounted fan heater? And how does it work?

Let us try to find out, point by point, in our short study.

How do wall-mounted fan heaters work?

A wide variety of fan heaters are available on the market today. While some of the same principles apply to most heaters, each make and model has several subtle variations, which make it difficult to proceed with a homogeneous treatment of this topic.

In fact, while many fan heaters run on gas, oil or other fossil fuels, i wall-mounted fan heaters they are normally powered by electricity. And, in this context, the primary component common to all electric fan heaters is the electrical resistance.

When a heater is turned on, the electrical current produced heats the nickel-chromium wire components - better known as heating coils - in the unit. Electricity is transformed into heat when the current passes through the resistance. And that's why electric fan heaters are also known as "resistance heating units".

The next step in the heating process depends on whether or not the heater has a built-in electric fan.

In summary, if there is a fan this will help suck the cold air into the heater. The air will pass over the heating elements and then be pushed out into the room (in short, an operating mode that is quite similar to that of hairdryers). This is a heating mode also known as "convection", because the heat is transferred through the air. Convection heaters are a good way to quickly heat a space by circulating hot air around the room.

If, on the other hand, there is no fan in the heater, then it means that the air will enter the unit from below. The air flow passes over the coils, is heated and finally finds its way out through the upper part of the device.

This type of electric heating is known as "radiant" heating - think of a conventional electric stove with a heating element, for comparison. And it's a good choice for small spaces and areas where you can be close to the heat source while it's in use.

What are the advantages of wall-mounted fan heaters

Have a wall-mounted fan heater autonomous, detached from a central heating, it allows to obtain several advantages that are certainly not underestimated. But what are these benefits?

First, we can only talk about them cost effectiveness. There are three main ways portable heaters will save you money:

  • you will only consume the amount of energy needed to heat the spaces in your home that are used. During the day, if most of the family is at school or at work, just turn off the fan heater;
  • they require a non-invasive installation. The units that can be mounted on the wall require only a few fixings, and therefore you will not have to carry out expensive infrastructure works in your apartment;
  • maintenance is easy and often do it yourself. Just follow the guidelines in the user manual and keep the unit clean. There is no need for expensive service calls and regular professional maintenance, as is the case with a centralized system.

The second big plus point we want to share with you is the respect for the environment.

In fact, as we have already partly mentioned a few lines ago, autonomous fan heaters allow you to heat only the areas that must be kept warm, in order to use less energy in general. Almost no energy is therefore wasted by converting electricity into heat, in order to make the best use of the energy that is paid for in the bill. Additionally, these units also help reduce the demand for highly polluting petroleum products such as oil and natural gas - especially if you choose a green electricity supplier.

A third point of merit of these units is certainly their greatness versatility. In fact, wall-mounted fan heaters are a perfect solution for heating places where central heating is not a viable option, such as a new bathroom or a small room. They also work well in homes that are still under construction or under renovation.

How to save money by using a fan heater

How can I save money by using my fan heater?

Succeeding is not difficult. In particular, to make sure that your fan heater is operating at its best of expected efficiency, to save on bills, make sure it is of sufficient power to adequately meet your needs, but at the same time it is not too powerful for the space it is in. . Using a simple wattage and BTU calculation you can accurately calculate the required heating capacity and purchase a suitable heater.

Furthermore, we recommend that you always turn off the unit when it is not needed. Remember that some types of wall mounted fan heaters take a few minutes to heat up, so you should check the manufacturer's guidelines to see if you need to wait a while.

Finally, remember that the maintenance of most fan heaters is an easy task to carry out, considering that professional maintenance will not be required unless you have problems with malfunction or overheating of the unit. However, do not attempt to repair the internal components of the fan heater yourself, as this could invalidate the warranty. With regular cleaning, we are confident that your fan heater will keep you warm for many years!
