How many watts do I need for a 30 m2 living room?

For a living room of 30 mu00b², you need between 1,800 and 3,000 watts of power. The exact requirement depends heavily on the insulation value of your home. In a modern house with an A++ label, 60 watts per mu00b² is sufficient, while an older home often requires 100 watts per mu00b². It is smart to distribute this power across two heaters for even electric heating in the living room.

Is an electric heater in the living room more expensive to use than gas?

That depends on your heating habits and whether you have solar panels. Although the average gas price in August 2026 is 1.48 per m², the tax on gas is rising faster than that on electricity. By only heating the living room when you are actually there, you save significantly compared to central heating that keeps the entire house unnecessarily warm.

Can I install the BEHA radiators myself?

Yes, you can very easily install the BEHA convectors yourself without the help of a professional. Each heater comes with a sturdy wall bracket and clear instructions. You mount the bracket to the wall, click the convector into place, and plug it into the socket. This makes it an ideal solution for those who want immediate results without complicated drilling and breaking into the walls.

Are electric convectors safe with children and pets?

Our electric convection heaters are very safe for households with children and pets. The surface of the heater gets warm, but never so hot that it causes immediate burns with a brief touch. Furthermore, the heaters are equipped with automatic overheating protection. There are no exposed heating elements or moving parts that curious fingers or paws can reach.

What is the difference between a convector with a steel front and a glass front?

The difference lies primarily in the appearance and the possibility of personalization. A steel front is robust and available in a paintable version, allowing the stove to blend in with the wall. A glass front, on the other hand, offers a modern, luxurious look that makes a real design statement. In terms of heat output, both types perform excellently, although glass often retains heat just slightly longer after being switched off.

How does the Wi-Fi control work if my internet connection drops?

If your internet connection is lost, the heater will continue to operate at the last set temperature. You can manually control the thermostat at that moment using the buttons on the device itself. As soon as the Wi-Fi connection is restored, the convector automatically resumes the weekly schedule programmed in the app. So you don't have to worry about being left in the cold in the event of a malfunction.

Do the BEHA heaters meet the latest environmental requirements?

Absolutely, all BEHA convectors meet the strictest ECODESIGN requirements applicable in 2026. This means that our heaters are equipped with energy-saving features such as an accurate weekly timer and open-window detection. These technologies are mandatory to maximize efficiency and prevent unnecessary energy waste, which directly contributes to a lower ecological footprint for your household.

Can I repaint an electric heater in any color?

Only our specific smart convectors with a paintable front are suitable for this. You can paint these fronts with standard water-based wall paint so that they match the exact color of your wall. It is not intended to paint our glass fronts or standard steel models. By choosing the paintable variant, you ensure that the electric living room heater becomes virtually invisible in your interior.

Electric living room heating: 10 ultimate tips

August 6, 2026 13 min read

electric heating for the living room requires more than selecting a single radiator based on square footage. An open living space with large windows, a well-insulated apartment, and an older terraced house can have completely different heat requirements for the same surface area. In this guide, you will discover which type of electric heating is suitable, approximately how much power you need, how to calculate consumption, and when supplementary heating is wiser than primary electric heating.

We focus on homes in Belgium and the Netherlands and compare convectors, electric radiators, infrared heaters, fan heaters, and heat pumps without exaggerated savings claims. With the power matrix, installation tips, safety check, and purchase checklist, you can make a choice that is both comfortable and technically sound.

Key points

Direct electric resistance heating generates approximately one kWh of heat from one kWh of electricity at the point of use. The type and control system primarily determine comfort, heat distribution, and duty cycle.
A convector is well-suited for even, quiet room heating; infrared is particularly powerful for a fixed zone or seating area.
Calculate power based on volume, insulation, glazing, exterior walls, and desired temperature, not just on floor area.
For targeted supplementary heating, electric heating can be practical. For long-term heating of a large living room, a heat pump is generally more energy-efficient.
The thermostat, weekly program, and app only save energy when they actually lower the temperature or usage time.

Electric living room heating: when is it smart?

Electric resistance heating uses the principle of electric or Joule heating: current flows through an element and is converted into heat. The major practical advantage is room-by-room control without pipes or combustion gases. You can heat the living room while bedrooms remain cooler. This is particularly interesting when you use the living space at fixed times or when expanding an existing water-based system is difficult.

The word “efficient” requires explanation. Virtually all electricity consumed ends up locally as heat, but direct electric heating does not generate multiple kWh of heat from a single kWh of electricity. A heat pump transfers heat from the outside air or the ground and can therefore require much less electricity for structural main heating. The right choice therefore depends on operating hours, insulation, desired flexibility, and investment budget.

When is electric supplementary heating a good choice?

You mainly use the living room and want to keep other rooms temporarily cooler.
The living space is reasonably to well insulated and has manageable heat loss.
You want quick extra comfort alongside a central system without new water pipes.
You have a suitable electrical connection and sufficient capacity on the circuit.
You can regulate accurately based on presence with a thermostat and program.

When to compare alternatives first?

In a large, moderately insulated living room that needs to remain warm for many hours daily, direct electric heating result in high annual consumption. In that case, first improve drafts, windows, roof, facade, or floor insulation, and compare an air-to-air or other heat pump. Milieu Centraal explains that a resistance heater delivers approximately one kWh of heat per kWh of electricity, while a heat pump utilizes ambient heat. Therefore, also read the independent explanation regarding electric heating with a heat pump.

Electric living room heating: types compared

The best technique depends on whether you want to heat the entire room air, a fixed zone, or only briefly. The comparison below goes beyond the maximum wattage.

Type	feeling of warmth	Sound	Strong application	Point of attention
Convector	Even heating of the room air	Very quiet without a fan	Longer living room heating	Free air circulation and correct power required
Electric panel radiator	Combination of convection and surface heat, model-dependent	Usually quiet	Fixed wall heating	Check assembly, control, and surface temperature
Infrared panel	Direct radiant heat on people and surfaces	Quiet	Fixed seating area or workspace	Sightline, mounting, and position determine comfort
Oil-filled radiator	Slow, even release and residual heat	Usually quiet	Longer temporary supplementary heating	Heavy; oil buffers heat but does not make the element more efficient
Fan heater	Quickly noticeable warm air	Fan audible	Heat briefly and locally	Less suitable for quiet evenings and prolonged use
Air-to-air heat pump	Heats air actively and quickly	Indoor and outdoor unit audible	Many hours of use and cooling in summer	Higher investment, installation and maintenance

Convection heat versus infrared

A convector heats air that circulates around the room by natural flow. This is suitable for a living room where multiple people move around and the entire space needs to be comfortable. Infrared heat primarily radiates towards what is within reach. This can be advantageous when you only want to heat the sofa or dining area, but a panel behind furniture or out of sight provides less immediate comfort.

Neither technique bypasses the basic bill: a 1500W resistance element uses a maximum of approximately 1.5 kWh per hour as long as the element is switched on continuously. Zone heating can, however, save total energy because a smaller area is heated for a shorter period. Research into local electric heating shows that the outcome depends heavily on how and where heating is deployed.

Electric radiator or convector?

Names are often mixed up in online shops. Therefore, look at the actual construction: does the unit have a fan, liquid buffer, open convection grilles, or a radiant front? Next, compare thermostat accuracy, surface temperature, warm-up time, weight, mounting, and noise. An expensive designer radiator with the same power consumption does not automatically produce more heat; you may be paying for materials, controls, finish, and lifespan.

Design and smart control: what delivers real benefits?

A living room stove is visible every day. Steel looks calm and robust, glass provides a sleek finish, and a suitable paintable front can visually blend into the wall. Never let design take precedence over free airflow, safe distances, or access to controls and sensors. Only paint any part that the manufacturer designates as paintable for that exact model.

Thermostat and weekly program

An electronic thermostat prevents the element from continuing to heat after the set temperature has been reached. A weekly program lowers the temperature when the living room is empty. Do not just look at the number of functions, but also at the setting range, measured temperature accuracy, calibration, frost protection, and behavior after a power outage.

Wi-Fi and app control

Wi-Fi does not make electric living room heating physically more efficient. The advantage arises when you remotely turn down a forgotten heater, use presence schedules, or control rooms separately. Check whether local control continues to work without internet, how long the app is supported, what data is processed, and whether multiple users can access it.

Ecodesign and product information

Local electric space heaters in the European Union are subject to Ecodesign requirements. These relate to efficiency, control, and product information, among other things. The European Commission publishes the current rules for local space heaters. An Ecodesign listing is useful, but it does not replace a heat loss calculation or an assessment of your specific usage situation.

How much power is needed for the living room electric heater?

Measure the length, width, and ceiling height, and then note the exterior walls, windows, insulation, ventilation, and adjacent unheated spaces. A living room with sliding doors and an open staircase loses more heat than an intermediate apartment of the same surface area. A professional heat loss calculation remains the best basis for primary heating.

Indicative asset matrix

For an initial orientation, a range of approximately 25 to 50 W per m³ is often used, from very well to moderately insulated. This is intentionally not a fixed standard. The table assumes a ceiling height of 2.5 meters.

Living room	Contents	Indication of very well insulated, 25W/m³	Average indication, 35W/m³	Indication moderate, 50W/m³
20m²	50m³	1250W	1750W	2500W
30m²	75m³	1875W	2625W	3750W
40m²	100 m³	2500W	3500W	5000W

Do not blindly add ten percent for every window; the type of glass and surface area are the determining factors. In the case of an open kitchen, mezzanine, or stairwell, the combined volume must also be taken into account. If the calculation exceeds the capacity of a single suitable appliance, spreading the load across two heat sources can improve comfort, but the total electrical load remains equivalent.

Calculate consumption and hourly costs

The formula is simple: power in kW × actual duty cycle × your electricity price per kWh. A 2000W radiator uses 2 kWh for one hour of continuous heating. If the thermostat switches the element on for half the time during that hour, the consumption is approximately 1 kWh. The actual cycle varies with outside temperature, insulation, setting, and heat from the sun, people, and equipment.

Total power	Consumption at 1 hour continuous	Current at 230V	Cost formula
1000W	1.0 kWh	approximately 4.3A	1.0 × your kWh price
1500W	1.5 kWh	approximately 6.5A	1.5 times your kWh price
2000W	2.0 kWh	approximately 8.7A	2.0 × your kWh price
3000W total	3.0 kWh	approximately 13.0A	3.0 × your kWh price

Use your own current rate; average Belgian and Dutch prices change and vary by contract. Also include other appliances on the same circuit. A kettle, oven, or dishwasher simultaneously with multiple radiators can significantly increase the circuit load. If you have multiple fixed appliances, have an electrician assess whether the distribution, wiring, and protection are appropriate.

Solar panels and dynamic rates

Solar panels can supply a portion of electricity consumption, but the greatest demand for heat often occurs during dark winter moments. Therefore, “heating with solar panels” does not automatically mean that all the electricity used is generated simultaneously on-site. With a dynamic tariff, you can sometimes shift to cheaper hours, but comfort, heat loss, and contract terms determine the result.

Electric living room heater: the best placement

Proper installation prevents cold zones and unnecessarily high settings. Install only where permitted by the manufacturer and observe minimum distances to the floor, windowsill, furniture, and curtains.

Under a window or against a cold exterior wall

A convector under a window can capture descending cold air and convert it into a rising stream of warm air. This is particularly useful with large glass surfaces. However, check whether curtains, a wide windowsill, or a sofa block the air circulation. With very well-insulating glass, another central position may also be suitable.

Open living room with kitchen

Calculate the total open volume and take into account the extraction, exterior door, and stairwell. One large radiator at the far end can result in an uneven temperature. Two properly regulated convectors in cold zones can distribute the heat more evenly. Together, however, they must fit within the available electrical capacity.

Infrared by the seating area

Mount an infrared panel with a clear line of sight to the location where heat is needed. A panel behind the sofa or high above an unused walking area provides less targeted benefit. Have ceiling or fixed wall mounting carried out in accordance with the manual and surface requirements.

Safety for children, pets, and textiles

Never cover a heater and do not use it to dry laundry directly.
Keep furniture, curtains, toys, and pet baskets outside the prescribed clearance.
Check surface temperature and select a child lock where relevant.
Connect a powerful device as prescribed by the manual, preferably directly to a suitable grounded outlet.
Do not use an unsuitable power strip, damaged cable, or coiled extension cord.
Ensure the smoke detectors are working and stop if there is discoloration, heat, or damage to the plug and socket.

Electric living room heating: 8 ways to limit consumption

Electric living room heating does not become more efficient simply by using a different brand name at the same wattage. The greatest savings come from reduced heat loss, a lower target temperature, smaller heated zones, and fewer operating hours. Therefore, start with measures that will also yield benefits with a future heat pump.

Seal visible gaps: check windows, exterior door, and connections, but do not block necessary ventilation openings.
Close interior doors: prevent warm air from unintentionally flowing into the hallway, stairs, or unused rooms.
Heat based on presence: have a program start shortly before use instead of maintaining the same temperature all day.
Lower the setting: every degree less reduces the temperature difference with the outside and thus the heat loss.
Keep the airway clear: a sofa, curtain, or windowsill in front of the convector obstructs heat distribution.
Use the sun: open curtains on the sunny side during the day and close them after sunset without covering the heater.
Measure instead of guessing: use an energy meter and compare consumption at different settings over similar cold days.
Insulate before scaling up: if the appliance is running continuously but not reaching the temperature, investigate heat loss first before adding extra wattage.

Practical example: 30m² living room

Suppose the living space is 30 m² and 2.5 meters high. Using a rough mean of 35 W per m³, you arrive at approximately 2625 W. This is not automatic purchasing advice: a well-insulated apartment can require less, while a corner house with an open staircase requires considerably more. Two convectors of, for example, 1250 W and 1500 W can distribute the heat across two cold facades, but together they consume a maximum of 2750 W when both elements are switched on.

If you primarily use one corner of the sofa for two hours, targeted radiant heat with a lower total output may be more comfortable than heating the entire volume. However, if the entire living room is occupied daily from morning to evening, the number of usage hours becomes high, and a heat pump warrants a cost comparison. Thus, the same living room leads to a different choice depending on occupancy and comfort zone.

Electric living room heater with BEHA: when is it suitable?

A BEHAwall convector is particularly suitable when you are looking for quiet, even heating and room-by-room control. For just one fixed seating area, infrared might be more logical; for a large living room that is heated for long periods every day, a heat pump comparison is worth considering. Choosing transparently prevents a convector from being sold as a universal solution.

Norwegian experience and calm wall models

Compare the available wattage, dimensions, thermostat, app functions, mounting method, cord or fixed connection, surface temperature, and warranty conditions for each model. View the current range of electric heating from BEHA and match the technical data sheet to your living room's heating needs.

Interior and multiple zones

A clean front and wall mounting save floor space. In an elongated or L-shaped living room, more than one smaller appliance can provide a more even result than a single source. Preferably use cooperating controls so that appliances do not unnecessarily interfere with each other. You can compare the available versions for Belgium and the Netherlands via BEHA Benelux

Electric living room heating: buying checklist in 10 steps

Determine the goal: local heat, supplementary heating, or daily primary heating.
Measure the full volume: include open kitchen, stairs, or mezzanine.
Inventory heat loss: insulation, glass, exterior walls, floor, ceiling, and ventilation.
Choose the heating principle: convection for room air, infrared for a fixed zone, or heat pump for many hours.
Calculate power: use the table only as a guide and have the main heating calculated exactly.
Create a placement plan: cold zones, airflow, curtains, furniture, and electrical outlets.
Check the circuit: total wattage, cables, grounding, and concurrent equipment.
Compare control: thermostat, weekly program, app, open-window detection, and fault behavior.
Calculate annual costs: estimated operating hours × kW × own kWh price.
Read terms and conditions: installation guide, warranty, app support, service, and returns.

Electric living room heating: conclusion and advice

Electric living room heating can be a flexible and comfortable choice when power, placement, and controls suit the space. For quiet, even heating, a convector scores highly. Infrared is interesting for a single seating area, and a heat pump deserves consideration when the entire living room needs to be heated for extended periods daily.

Calculate costs using your own electricity tariff, do not expect solar panels to immediately cover every winter kWh, and have multiple heavy appliances electrically assessed. Do you want to compare a fixed wall convector with a clean design and smart control? Then view the range of electric living room heating from BEHA and make your choice only after checking heat loss and the product manual.

Frequently asked questions about electric living room heating

How many watts do I need for a 30m² living room?

At a height of 2.5 meters, that is 75 m³. A rough range of 25–50 W per m³ gives approximately 1,875–3,750 W, depending on insulation and conditions. Large windows, exterior walls, an open staircase, and the desired temperature can alter the result. Have a heat loss calculation performed for primary heating.

How much does electric living room heating cost per hour?

Multiply the total power in kW by the actual duty cycle and your kWh price. A total of 3000W uses 3 kWh per hour when the elements are on continuously. Thermostat cycles can lower the average, but this depends on heat loss and setting.

Is an electric radiator more energy-efficient than a convector?

Not automatically. Both consume approximately the stated electrical power when the element is on for direct resistance heating. Differences in control, heat distribution, warm-up time, and usage can affect actual consumption. Therefore, do not compare solely by product name.

Can electric heating serve as primary heating?

Technically, this is possible if the capacity and installation are suitable, but it can consume a lot of electricity in a large or poorly insulated living room. For long-term daily use, compare a heat pump and improve the insulation first. Electric convectors are often more attractive as zone or supplementary heating.

Is a convector safe around children and pets?

Follow the product manual, clearances, and assembly instructions. Check the surface temperature, use a child lock if available, and keep toys, curtains, and pet baskets away. Overheating protection reduces the risk but does not replace correct use.

Can I install a BEHAradiator myself?

You can install a plug-and-play wall-mounted model according to the manual, provided the surface, distances, and socket are suitable. Have fixed wiring, new circuits, or any doubts regarding capacity assessed by a qualified electrician. Always check for pipes before drilling.

Does Wi-Fi control work without internet?

This depends on the model and the app. Before purchasing, check whether local control on the device remains available and which functions work without a cloud connection. The heater must remain safely controllable if Wi-Fi or the internet temporarily fails.

Can I paint over any electric radiator?

No. Only models or front panels explicitly declared suitable by the manufacturer may be finished according to their instructions. Keep grilles, sensors, and controls clear. Unapproved paint or modifications may affect heat output, safety, and warranty.
