It is also not designed for this and generally does not have to operate continuously, it would not be profitable anyway.

The aim is to postpone the ignition or on the contrary to anticipate the extinction of the main heating to limit energy consumption. The space heater can also be used as a supplement in little used rooms or to increase the temperature where you are. Finally, an autonomous radiator can be a valuable help in the event of a power failure!

The space heater comes in different shapes and sizes. It is often mobile and portable, however an additional heater can also take a fixed in the room, wall or standing. The energy used is variable: electricity, oil, gas, ethanol… It can even be heating for the exterior.

Auxiliary heating

The Different Types Of Auxiliary Heaters As

you have already seen, many types of heating appliances can be used as auxiliary heating. We have also granted specific articles to many of them:

Electric auxiliary heating

  • The convector : light inexpensive radiator, it quickly warms the atmosphere but has no inertia, tending to create zone effects cold and is quite energy-intensive.
  • The fan heater : compact and light, it moves easily. It propels warmed air far into the space, perfect for small areas. Today, this type of device is often a ceramic heater : the heating element is a resistance covered with ceramic, the air is softer, less drying than a conventional fan heater.
  • The radiant radiator : this radiant heating also provides rapid heat gain for a minimum of space. Its warmth is very pleasant, similar to the rays of the sun. It is a radiator that can be ultra flat and very stylish!
  • The false fireplace : it is both a decorative element and an auxiliary heater. The structure represents a trompe-l’oeil fireplace, with a luminous flame effect. It hides a fan heater to gain a few degrees and a lot of well-being!
  • The towel dryer : it is the emblematic auxiliary heating of the bathroom. Most of the time electric, it can also be water, connected to the central heating system. The heating methods differ: inertia, radiation, convection, with a blower, mixed… The towel dryer heats the bathroom and dries your laundry, with different formats and multiple functions.

Auxiliary gas heating

The stove has the advantage of being able to operate independently, ideal in the event of power cuts or simply to limit consumption. Often mounted on wheels, the stove can be easily installed anywhere, but it is quite bulky and unattractive. The technologies differ: catalysis, infrared, infrared, for indoors or outdoors… All use a standard 13 kg gas cylinder, sometimes adaptable with a 6 kg cube regulator.

Auxiliary heating with oil

  • The stove can be autonomous or connected to electricity, it all depends on its type: wick stove or electronic stove. The first is elementary and manual with a battery and a burning wick that must be changed regularly. The second is much more advanced and secure, it embeds protections and programming systems allowing great comfort and energy saving. Above all, it can be an odorless oil stove, much more pleasant to use on a daily basis!
  • The ethanol fireplace offers a very contemporary design whose appeal is above all decorative. The calorific contribution is however present, proportional to the size of the burner, the bioethanol fireplace is therefore used for auxiliary heating. Free-standing or wall-mounted, special attention must be paid to safety (not practical with children) and good ventilation of living spaces.

Supplementary heating with wood

The stovestovepellet and the be used as supplemental heating. Indeed, in the absence of specific installation and in large houses, the heat produced will not reach the most remote rooms. However, insofar as the stove is generally installed in the living room, it is he who will warm you up most of the time while the other spaces can occasionally use one of the models from our list!heater…


muchAuxiliary heating ?

The choice of an auxiliary heater depends above all on theuse you intend to make of it and on its destination room. Gas or kerosene stoves that completely do without electricity can serve you anywhere, with no wires lying around and even in the event of a power outage. To heat the additional rooms, which are not very busy, a small electric heater will prove more practical. Finally, if it is just a matter of gaining a few degrees in the living room, all models will be suitable. However, it will be necessary to take into account the constraints and possible dangers depending on the configuration of your home. Take care of the aesthetics because you will live with it all winter! In general, other criteria should be observed:

The operating cost of the auxiliary heating

The purpose of the auxiliary heating is certainly not to blow up the energy bill. You must therefore seriously consider the price of fuel, which will represent a budget throughout the heating period. Here is an average of current energy costs:

EnergyAverage price per kWh
Bottled gas$0.14

Energy rates for auxiliary heating


is more or less the same for all types of heaters, the power required is proportional to the space to be heated. Count on average 1000W for 10 m², or 100 W per square meter. Calculate as follows:

Length x width x 0.01 (kW)

Calculation of the power required for an auxiliary heating according to the surface of the room (m²)

In the bathroom, it is better to count a little more for rapid heating of this comfort space, approximately 1200 W for 10m². Conversely, if your home is very well insulated, 600 watts will be enough to properly heat a living room of 10m².

Be careful, if the ceiling height is particularly high (above 2.50 m), you will then have to take the volume into consideration. In this case, use the following operation:

Length x width x height x 0.04 (kW)

Calculation of the power required for an auxiliary heater according to the volume of the room

In the case of general-purpose use, in several rooms in the house, you will always take into consideration the largest space by preferring heater models with several power settings.

The safety of the auxiliary heater

The matter here is to be taken very seriously because certain auxiliary heaters are not without risks. Both oil and gas stoves and bioethanol fireplaces pose a risk ofcarbon monoxide poisoning. Even if the models are now more sophisticated and fitted with safety devices, it is essential to ventilate the spaces well, to take care that nothing touches it (curtains, objects, etc.), not to use this type of heating in a room. It will also be necessary to pay attention to children and animals because the walls can be very hot.

Electric heating is much safer for the whole family. It is generally accompanied by overheating protection, sometimes with anti-tipping safety (depending on model). In the bathroom, the space heater must necessarily be class 2 and at least IP21 to meet electrical standards and not be afraid of a small splash of water.
