One of the greatest achievements of the Industrial Revolution, the ceiling fan also called by some like the ceiling fan. It is still one of the most sensible solutions for home comfort, despite having other much more sophisticated competitors and modern.
After more than a century, it's still an effective device in refrigeration at home , which, moreover, can also be can be used in winter.
More important is the practical side of the fan, its healthy appearance (Remember the article on negative effects of air conditioning in health) or energy savings they use very little electricity!
To choose the best device for ventilation household , we have to look at some aspects important. And we start by knowing the types…

Although nowadays the variations of form and models in the types of ceiling fans we can count them almost hundreds adapting to any situation or Embedding itself in any object or part of the house, yes that it is true that from the perspective of refrigeration for housing , we could distinguish the following types:
Inside a ceiling fan model – which is the case study – we can find some variations that respond to technical solutions or utility:
It is the angle where the blade directs the wind . It is a technical aspect that every manufacturer must have influenced whose value is decisive on the aerodynamic efficiency , determined by the called angle of attack.
A wider blade will create more air movement with one pitch steeper. Find the right size, depending on the space the room, is the ideal way to choose your fan… What size fan do I need for a room?
In addition, the height of the ceiling does matter before an installation and for higher ceilings, we will need a vertical rod that will take the fan blades to a minimum distance and thus being able to feel the
It is the speed with which the blades of the apparatus rotate in a determined speed. Here the engine plays an important role which is normally coupled with the price of the device… What rotation speed do I need in a fan? … Each room requires a range appropriate fan rotation speeds:
Remember to always look at the instructions provided by the manufacturer, are essential for both installation, technical characteristics or how to understand the operation of the device and its possibilities.
The most powerful motors of the fans of ceiling move more air, so these determine which ceiling fan gives more air . To see
The advantages of a fan with a DC motor compared to one with AC motor:
The advantages of a fan with an AC motor compared to one with DC motor:
In Europe, with Regulation (EU) 2017/1369, establishes a framework for the Energy Labeling of energy-consuming appliances in the home. In Specifically, the part of the regulations that affects the domestic ventilation units (HERE your query) gives us the following labeling that we must consider in a purchase:
Remember that green is the most efficient and red is the most efficient. less, and we also have to consider the issue of noise. Remember our article on 30 tips to save electricity at home, worth reading!
As a fact, there are two strategies to generate a increased air movement , which are;
In both cases, energy consumption is increased, but increasing the fan speed increases the power consumption much more than the increase in the size of the cross.
From the Ventiladorestecho.com portal they offer the following infographic that you can see an interesting summary with tips on these air conditioning systems .
The first premise is that we must cover our needs and each home has specific ones. it is not worth arriving to the store and buy the fan on sale.
These devices that remove the air in a room can also have other accessories; light remote control ventilation in winter, etc. You have to do a series of questions that meet our needs….
| Before buying, you have to ask you |
| What is the performance I need on the device? either What surface do I have to ventilate? |
| What energy efficiency scale do I want to buy? (Remember that the A+++ – Green, is the highest and, therefore, so much more expensive) |
| What maximum noise level do I want? (Practically all of them are already very quiet, except the cheaper) |
| What design does it have to have to fit the home decor? |
| What extras do I want it to have? (Light – let it be LED, remote control, that is reversible, number of speeds ventilation) |
Before you buy, always compare prices. Look at the prices in large stores such as Corte Ingles , Ikea, Carrefour , Leroy Melin , Media Markt . And always look at Amazon offers, sometimes you can save a lot euro.
You should compare devices and in several stores!… Search brands recognized by manufacturers; Casafan , Westinghouse , Orbegozo , The Modern Fan , Faro or brands high design like Sintra or STem.
Power usage varies by model. consumption of watts ranges from 15 to 30 watts at low speed, 30 to 50 watts at medium speed and between 50 and 100 watts at high speed. On average per year, it consumes about 800 kWh.
In the following comparative table we can verify the difference in consumption per day and month, between different devices of air conditioning and types of fans for house most common:
But, what happens if we decide to invest more in a device of AA with an ultra efficient energy rating, of A+++:
Remember that we are talking about a standard fan (Not A+ rating, representing 95% of sales)
We must take into account that we are in front of a device electrical and therefore requires maintenance, the way easier is to see the tips for cleaning a ceiling fan using the following infographic:
First we need to understand a simple question… Why do the fans cool? Actually, they are considered machines of fluid and cannot lower the air temperature, but, they can make
The moving air serves to increase the sensation of cold , this movement favors the evaporation of moisture from the skin. our sweat, evaporating, "steals" part of the body's heat, it's that simple! But… How does a ceiling fan work?
The trick really is to change the movement of the direction of its blades… What is the correct direction spin on a fan?
Not only do they give us that sensation of coolness during the hottest seasons, but rather they also help us improve efficiency heating energy in winter , (See article on air conditioning systems for homes) and that when the blades rotate clockwise clock, the fan blows up the cold air in the room and when they rotate in the opposite direction, the fan raises the hot air.
If you are a DIY handyman, then you can always learn how to install a cooling fan ceiling by professionals and practice it later at home (See the following video by Leroy Merlin). If you don't dare, always remember to ask for an invoice to be able to claim if applicable.
The advantages of installing this type of device for to refresh the house are many compared to other more complex, but they are certainly not as effective. The main advantages:
The main advantages of air ventilators roof are palpable that combined with the awnings that we can install at home (See advantages of using awnings in the housing) can be a very good solution to combat the heat.
