Do you spend more an electric radiator or an oil radiator? Thinking about the cold that these days is good to see what alternatives we have to heat the house, and among the many that we find the oil radiators seems one of the most feasible and recommended, although we may also find some disadvantages. Be attentive because we analyze everything about oil radiators.
What is an oil radiator
An oil riser is a radiator that is connected to the current by means of a plug and is capable of heating a room or any room in the house through a process that involves heating a thermal fluid inside the heater once it has been turned on.
This fluid (which we call oil) is specially formulated and is the one that distributes heat evenly through the radiator, transferring heat to the metal, which in this way, through the radiation, so that it transports heat to the room. Then, the heat circulates around the room by natural convection, since any air that radiates against the radiator. This causes the whole room to heat up eventually, since the coldest air will reach the back of the room, will come into contact with the radiator and will also heat up.
Energy-saving oil radiators
Later we see the advantages and disadvantages of oil radiators but basically we can say that the current models are provided with gels and thermodynamic liquids inside the radiators which have excellent heat retention properties. Therefore, these heaters do not have to work hard to maintain their ideal temperature, which makes them very energy efficient and converts them into low consumption radiators.
This way you can save energy and money, since the radiator will turn off automatically once you have reached the desired temperature and you can still feel its heat for a period of time afterwards. Radiators filled with oil are, therefore, suitable options for larger rooms and rooms that are in constant use.
Virtually all oil radiators sold on the market today (if not all), are low power because they only use an average of between 2,000 and 3,000W of power, keep the heat once they have been turned off and their design is quite light; in fact we can buy them with wheels to take them where we want or to hang them on the wall.
Oil radiators advantages and disadvantages
As we have explained, the oil radiators work connected to the electrical network and heating resistances that give heat to a fluid or oil that is what will emit the heat. Unlike “pure” electric radiators that work only with resistors or use a fan, oil heaters can keep the temperature a little longer, but the expense is similar.
A 1000W radiator consumes that amount either of oil or electric resistance. It is the same example as a kilo of grass or a kilo of steel. The feeling is that the oil spends less. In fact they spend the same only as oil retain heat longer after shutting down, because the fluid is still hot.
Advantages of oil radiators
Oil radiators are cheaper than other electric heating systems like those of blue heat. The price of this type of radiators is between 69 and 179 euro. They are quiet; do not emit noise unlike other systems that emit light hum.
They are comfortable and portable and can enjoy the heat in any place where you have a plug, since they do not need installation. Most, like electric ones, have a thermostat to be able to program them, for example half an hour before arriving home or so that when you wake up the area is hot.
They do not generate waste. Furthermore as the oil that they have in their inside is within the coils of the radiator and never burns, they do not have to be replaced or recharged.
I go out cleaning and use it properly, it does not require maintenance.
They keep the heat for some time (between 45 minutes and one hour depending on power) once they are turned off.
Disadvantages of oil radiators
They are slow in heating and, if you are looking for an instant heat, the oil is not the most suitable. Keep in mind that these radiators have an approximate heat output between 1.5 and 3kW, so until you feel the heat goes on for a while. The advantage is that after they are turned off they continue to emit heat for some time.
They spend a lot, even if they turn off every so often if the radiator is 1500 Watts and you have it lit hours a day, you will notice it on your electricity bill.
They are a bit big – although there are small radiators, they barely heat up – they are bulky because they take up space when storing them.
They are not suitable as a single heating system; there are other more economical and versatile. Oil radiators are more a support or reinforcement for localized areas.
Difference between oil radiators and electric heaters
In electric heaters, a fan is used that expels hot air. In oil radiators the hot liquid is stored in coils or radiator compartments. The heat works by convection and the emitted heat is transmitted to the environment without any fan.
Electric heaters give heat instantly while oil heaters take much longer to produce thermal sensation.
As the heat is emitted the area near the radiator is heated, this type of radiators can have different powers in the same apparatus 800W, 1000W, 1500W, or 2000W are the most common.
The vast majority has a thermostat to turn off and on, it is in these cases when the oil takes advantage of an electric convector that does not accumulate temperature while the oil radiator still turn off after a certain time to emit heat.
