Fan Heater: recommendations on which to choose
A fan heater is a machine designed to heat the surrounding environment quickly and with reduced consumption.
There are several variants of this instrument on the market, which we will go into in more detail in the following paragraphs. But, the first point on which we will focus, given its importance, is the type of power supply, which can be very varied to meet the needs of everyone as much as possible. The differentiation, according to fuel type, can be broken down as follows:
- oil-fired hot air generator
- hot air gas generator
- electric hot air generator
Now let's analyze them one by one in detail so that we can get a complete idea of the subject in question
Oil-fired hot air generator
The oil-fired hot air generator works using a burner that generates a flame thanks to the mixture of air and oil inside the combustion chamber. Through a heat exchange with the flue gas circle, the air also passes outside the combustion chamber to the outside of the machine itself, so the surrounding environment heats up in a short time and is, therefore, the ideal solution in "emergency" situations for those who need to heat a specific area in no time.
Gas hot air generator
The gas hot air generator has a very similar operation to a direct hot air generator, in which there is no chimney to expel fumes. Still, everything that is burned is also fed into the room together with the hot air. That's why this type is not suitable in closed environments, but only in those at least semi-open (e.g. fairgrounds, outdoor venues, etc.), where there is a minimum of recirculation of external air and oxygen.
Electric hot air generator
The electric hot air generator is an efficient device for many applications because it can give off clean and safe heat. This too, like the first, is particularly suitable for temporary or emergency heating, with the further advantage that it is simple to use and is also easily transportable. Furthermore, it produces zero emissions, does not involve the purchase of fuel, and at the same time, the impact on the bill is not as high as one might expect.
Once the issue of the power supply has been examined in-depth, it is essential to specify that the hot air generator branches off into several types of products, which specifically are:
- hot air cannon
- industrial hot air generators
- electric heaters
- electric stoves
Let's see together what is meant by each product!
Hot air cannon
The hot air cannon is a heat generator designed for large spaces and difficult to heat with classic devices... This is why it is ideal in stables, greenhouses, buildings still under construction, gyms and much more. Although it is a heat generator intended for more "niche" contexts and more associated with professional use, it is very versatile as it can be portable/wheeled. Consequently, it can be easily moved wherever it is needed.
Industrial hot air generators
The hot air generator is generally intended for installation in rather spacious rooms, but there is another type suitable for even larger rooms: industrial hot air generators.
These are easy to install and thanks to the availability of their low-cost fuel, it is possible to reduce heating costs significantly, also because the ventilation technology eliminates the waste related to heat loss.
Electric heaters are particularly suitable for small rooms where an independent heat source not dependent on the domestic heating system is needed. They are, in most cases, small, handy, versatile and even safe (since they are always equipped with a protective grill) and are the ultimate solution for those who need to heat, without the use of any fuel, environments such as offices, bedrooms, small cellars or the bathroom!
Ventilated electric stoves are an undisputed must in every home or office because they are resistant to wear and tear, and can be transported from one room to another without any problem. Electric stoves have super intuitive function controls so that they are within reach of even so-called users that "do not get along" with technology.
Also, despite their compact design, they guarantee high efficiency that at the same time, does not take anything away from healthy air circulation... All this with minimal electricity consumption compared to conventional heat generators!
Fields of use
There are several fields in which you can take advantage of the benefits offered by the hot air generator, but the following are the most prominent ones:
- Shipyard construction
- Clubs, bars and restaurants
Their use, however, is not only limited to heating, but also drying the paint, especially on ships, or plasters and substances applied to floors.
Noise is perhaps the only most noticeable disadvantage of using hot air generators, but this does not mean that it should be omitted or somehow concealed.
There is a solution that consists of placing the pipes outside the structures and then channelling them inside, so as not to hear annoying noises. It is also possible to choose the materials of the pipes that generally branch out from the classic rigid structures to those made of similar fireproof fabric
