What Is A Fan Heater?
A fan heater is essentially a heater that operates by using a fan to push air over a heating element (e.g. nichrome, resistance foil, etc.). When the air passes over the heating element, it gets heated up and is consequently pushed out of the heater. In this way, a fan heater warms up a room.
There are two types of fan heaters: electric and externally vented. Electric fan heaters draw electricity to run. A current passes through the heating element, which then transforms the electrical energy into heat energy. The fan present within sucks in air and pushes it towards the heating element where it gets warmed up rapidly. This warm air is blown out of the heater and warms up the entire room.
Contrary to electric fan heaters, externally vented, non-electric fan heaters use combustion fuel (e.g. gas, kerosene) to operate. Except for the energy source, they work pretty much like their electric counterparts.
Electric fan heaters have an advantage over externally vented fan heaters as almost all the energy that it draws in goes out to the room in the form of heat. This is not the case with externally vented fan heaters as some heat is always lost in the process. However, the cost of running an electric fan heater is higher than that of an externally vented fan heater.
Features Of A Fan Heater
Here are the basic features of fan heaters:
- Today, almost all modern fan heaters come with a power setting to regulate the power output.
- Some models may have a thermostat that can turn off the heating when the desired temperature is attained. However, these thermostats cannot maintain perfect control over room temperature as they are usually attached to the body of the heater and senses the room temperature from there, which may not be accurate all the time.
- Externally vented fan heaters use common heating elements and can generate an impressive heat supply.
- In fan heaters equipped with a hydronic heating system, hot water tubing is used.
Power Consumption Of A Fan Heater
On an average, the power consumption on fan heaters can range from 1,000W to 3,000W. Though the more advanced models use less energy compared to the outdated models, fan heaters are not an energy efficient option. One electric fan heater can consume up to three times more electricity than a 4 to 6 star reverse cycle air conditioner heater.
Usage Of A Fan Heater
While residential fan heaters are used for heating homes, offices, and such small living spaces, industrial fan heaters are used in large areas such as warehouses, shipping containers, factories, etc.
A fan heater is an efficient way to heat up your room during winters. To warm up the room and save energy simultaneously, set the fan heater at a lower temperature and insulate the room. This way, the hot air will be distributed evenly throughout the room without the heat escaping outside.
Heating And Ventilation
Every house in cold countries has a heating and ventilation system. Heating refers to the process of heating up the home by using appliances that generate heat (room heaters and fan heaters) or through a central heating system. In a central heating system, there is a boiler, a furnace, or a heat pump to heat water. It is positioned in a central location within the home from where the heat is transferred to different parts of the house by convection, conduction, or radiation.
Ventilation is the process by which the stale air within the house is exerted out to be replaced by fresh and clean air. It involves both, the exchange of the internal air with the outside air and air circulation of air within the house. In the process, bad odours, moisture, smoke, heat, dust, and carbon dioxide is pushed out of the house and replenished with oxygen. Proper ventilation is essential to maintaining good air quality within your home. It is very beneficial to your health as it drives in oxygen inside your home that boosts up your metabolism and takes out the harmful pollutants (carbon dioxide, smoke, and odour). Furthermore, ventilation is a great way to cool your house naturally.
