Imagine this: it is a clear evening in 2026 and you are enjoying yourself with friends on your terrace, but secretly you wonder if that pleasant warmth will soon give you an unpleasant surprise on your energy bill. It is a recognizable dilemma for many pleasure-seekers who are torn between the coziness of an outdoor space and the invisible costs of electric heating. After all, we all want to experience the security of a warm summer evening without literally blowing precious energy to the stars.

In this guide, you will discover the facts about patio heater consumption, and we calculate down to the cent exactly what an hour of sitting outside actually costs you. You will learn why a modern infrared heater is up to 60 percent more efficient than an outdated gas heater and how proper placement effectively prevents any form of heat loss caused by wind. We offer you a transparent cost overview for 2026 and practical tips for heating your patio sustainably and stylishly, so you can continue to enjoy it with peace of mind and a low energy bill.

What determines the actual consumption of a patio heater?

The starting point of any energy calculation is the power, expressed in Watts. This number indicates how much power the device draws from the mains. A device with a power of 2,000 Watts consumes exactly 2 kilowatt-hours (kWh) per hour that it operates at full power. However, this figure tells only half the story. The actual efficiency depends on the efficiency with which that electricity is converted into palpable heat on your skin. With a high-quality infrared patio heater, consumption of a patio heater is therefore a sum of technical specifications and the way in which the heat is emitted.

Power versus warmth perception

There is a fundamental difference between the technical input and how you experience the heat. While a classic heater attempts to warm up air molecules, infrared radiation works exactly like the sun. The rays travel through the air without heating it and only release their energy once they strike an object or person. As a result, a 1,500-watt infrared panel often offers more comfort than a 2,500-watt electric heater that merely blows warm air. You feel the pleasant radiation immediately on your skin, even when the ambient temperature is low. This makes the experience much more intense, allowing you to often set the device to a lower setting without sacrificing comfort.

The influence of external factors

The location where you place the heater determines the final energy bill. On an open terrace, the wind has free rein, which is crucial for your choice. If you use a long-wave infrared heater here, the heat will blow away before you can fully enjoy it. For exposed spots, we recommend short-wave infrared, such as the well-known Gold lamps. This radiation is more powerful and insensitive to wind gusts, making the outdoor patio heater

In addition, installation plays a key role in efficiency. Pay attention to the following points during installation:

• Mounting height: If you hang a heater at a height of 3 meters instead of the recommended 2.10 meters, you lose up to 40% of heat intensity where you are sitting.
• Shelter: A glass wall or a sunshade retains heat longer, allowing the thermostat to switch off sooner.
• Warm-up time: A more powerful model with higher wattage is sometimes more economical because the desired temperature is reached faster. As a result, the appliance does not need to run at full power for as long to create a comfortable zone.

By intelligently assessing the specific situation of your terrace, you avoid unnecessary energy costs and enjoy healthy, radiant warmth to the fullest.

Cost overview: What will you pay per hour in 2026?

The energy consumption of a patio heater is a decisive factor for many people when purchasing a new system. In 2026, the average price of electricity is expected to be around €0.33 per kWh. This means that with the right choices, you can very specifically control your monthly energy costs. Thanks to the direct radiant heat of infrared technology, hardly any energy is lost to the ambient air, ensuring that every euro you spend actually contributes to your comfort.

The calculation for your terrace

You can very easily calculate the cost of sitting outside for an evening yourself. The formula we use for this is: (Wattage / 1000) x operating hours x kWh price. Let's take a concrete example with a standard 1500-watt unit. If you use this at full power for two hours at a rate of €0.33, you pay only €0.99. So, for less than the price of a cup of coffee, you can enjoy pleasant warmth for an entire evening. It is smart to check your energy contract in this regard; 62% of households now use dynamic tariffs, where patio heater usage during off-peak hours in the late evening often turns out to be another 15% to 20% cheaper.

Costs in perspective

To fully understand the costs, it helps to compare them with other appliances in the home. Heating for an hour with a 1500W heater consumes approximately the same amount of energy as running one and a half wash cycles at 40 degrees. With a more powerful 3000W heater, often used for larger open terraces, these costs double to about €1.00 per hour. Because you usually use a patio heater only occasionally, for example thirty evenings a year, the impact on your total annual bill remains limited to an amount between €45 and €65.

Modern technology makes saving even easier. Approximately 85% of new models today are equipped with smart controls and dimming functions. By setting your device to 50% or 75% of its power as soon as the first chill is gone, power consumption drops immediately. This creates a sustainable solution that fits perfectly with a gas-free lifestyle. Do you want to know which power output best suits your situation? A high-quality patio heater offers the flexibility you need for any outdoor space.

Switching to electric outdoor heating is a logical step in the current energy transition. It not only offers more safety than traditional gas heaters, but it is also much kinder to your wallet in the long run. For those who also wish to create a healthy indoor climate, we offer extensive advice on the possibilities of living room heating with infrared technology.

Electric vs. Gas: Which patio heater is the most economical?

When looking at patio heater consumption , you often see a battle between gas and electricity. Many people choose gas out of habit, but the hidden costs add up quickly. With a gas heater, you don't just pay for filling the bottle. You have to deal with the fuel for the trip to the filling station, the physical storage of heavy bottles often weighing 10 to 15 kilograms, and the time spent lugging them around. Electric infrared heaters are simply plugged into your existing power grid. As a result, indirect costs and effort are virtually nil. Moreover, gas heaters require regular technical maintenance to prevent blockages in the nozzles, whereas an electric version is completely maintenance-free.

Efficiency and energy loss

The biggest difference lies in the physical operation of the devices. Gas heaters work on the basis of convection; they heat the air around the burner. In an outdoor environment, this is highly illogical, because the slightest breeze immediately blows the heated air away. In practice, up to 80% of the heat produced by gas heaters is lost to the open air before it reaches your skin. Infrared panels work on the principle of radiant heat. They directly heat the objects and people in the radiation zone, exactly as the sun does. This minimizes energy loss and ensures that the patio heater's energy consumption is used much more targeted and efficiently. View our full range of patio heaters for models that make optimal use of this technology for your outdoor space.

Sustainability and the future

With an eye on 2026 and the acceleration of the energy transition, the shift towards gas-free living is becoming increasingly prominent. Electric outdoor heating fits perfectly into this picture. In combination with green electricity or your own solar panels, infrared is the only truly CO2-neutral option for a comfortable patio. While a gas burner often loses efficiency over time due to soot buildup and wear, high-quality IR lamps have an impressive lifespan of more than 5,000 operating hours. This means that, with an average use of 60 evenings per year, you will enjoy a constant heat output for over 20 years without having to replace any parts. It is a future-proof choice that effortlessly combines aesthetics and sustainability.

• Gas: High heat loss (80%), cumbersome to use, not CO2-neutral.
• Infrared: Direct heat on the body, maintenance-free, perfect match with solar panels.
• Lifespan: IR lamps last up to 5x longer than the average lifecycle of a gas burner.

Smart tips to reduce your patio heater's energy consumption

Lowering energy costs starts with a smart approach to your outdoor space. After all, you don't want to heat the entire garden, but only the spot where you relax. By carefully considering positioning and utilizing modern technology, you keep patio heater consumption under control without compromising on that delightful warmth. Small adjustments to the setup can quickly make a difference of 20% to 30% on your bill.

Placement and zoning

Strategic wall mounting is always preferred over a freestanding model. Freestanding heaters often lose up to 30% of their heat because the radiation goes in all directions, including to areas where no one is sitting. With a wall-mounted model featuring a good reflector, the heat is directed straight to the seating area. When purchasing, pay attention to the quality of the mirror behind the lamp. A high-quality reflector increases efficiency by an average of 15% compared to budget models. Set the beam angle precisely to approximately 45 degrees for the most efficient coverage of your patio furniture.

Technology and automation

Modern technology helps you combat waste. Motion sensors are a smart investment for both the hospitality industry and private individuals. They ensure that the heater only consumes energy when someone is actually present. This prevents unnecessary costs when you just step inside for a moment. Additionally, you can easily connect the system to your home automation. With a smart timer, you prevent the heater from accidentally staying on all night. Always use a remote control with a dimming function. On a mild evening, 50% of the power is often sufficient to break the chill, resulting in immediate and significant savings on patio heater consumption .

In addition to technological gadgets, physical barriers play a major role in maintaining comfort. Consider the following practical solutions:

• Install a windbreak or glass wall. Wind can reduce effective radiant heat by as much as 50%, forcing you to turn the heater up unnecessarily high.
• Use a timer that automatically cuts off the power after 30 or 60 minutes, so you never forget to switch off the device.
• Choose a heater with short-wave infrared radiation. This technology is less sensitive to wind than long-wave, meaning less energy is lost to the ambient air.

By being mindful of the settings and surroundings of your terrace, you create a sustainable outdoor space where comfort and efficiency go hand in hand. It is all about the right heat at the right time.

Frequently asked questions about the consumption of a patio heater

How many kWh does an average patio heater consume per hour?

An average patio heater consumes between 1.5 and 2.5 kWh per hour when set to the highest setting. This consumption is directly linked to the power output of the unit; a 2000-watt model consumes exactly 2 kWh per hour. At an electricity price of €0.30 per kWh, an hour of comfortable warmth therefore costs you approximately €0.60.

Is an electric patio heater cheaper to use than a gas heater?

Yes, an electric infrared heater is up to 70 percent cheaper to use than a gas heater. While a 10-kilogram gas cylinder is often empty after 12 hours of intensive use, the consumption of an electric patio heater remains consistently and predictably low. You pay an average of €0.60 per hour for electricity, whereas the cost of propane gas quickly rises to €2.50 per hour.

Can I plug my patio heater into a standard wall socket?

You can easily connect a patio heater with a power output of up to 3600 watts to a standard 16-amp socket. It is advisable not to place appliances exceeding 2000 watts on the same circuit as other high-power consumers. For safe operation, we often recommend a slow-acting C-type circuit breaker in the fuse box, as the short start-up peak of infrared lamps can sometimes cause a standard fuse to blow.

Does wind affect the consumption of my infrared patio heater?

Wind has virtually no influence on the sensation of warmth or the efficiency of a short-wave infrared patio heater. Unlike gas heaters that heat the ambient air, infrared radiation directly heats your body and the objects on the patio. As a result, the patio heater's energy consumption remains extremely efficient, even when a strong breeze of force 4 blows across your patio. The heat simply does not blow away.

How many watts of patio heating do I need per square meter?

On average, you need 175 to 250 watts of power per square meter to comfortably heat an outdoor space. On a well-sheltered terrace, 175 watts is often sufficient, while an open terrace exposed to the wind requires closer to 250 watts per square meter. Therefore, for a 6-square-meter seating area, you need a heater of at least 1,500 watts for optimal results.

Are there subsidies for energy-efficient heating of my terrace?

There are currently no national subsidies for private individuals, but entrepreneurs can benefit from tax advantages such as the Energy Investment Allowance (EIA). Through this scheme, companies can deduct up to 40 percent of investment costs from taxable profit. This makes the switch to sustainable infrared technology a financially smart choice for the hospitality industry in 2026.

What is the lifespan of an infrared lamp in a patio heater?

A high-quality infrared lamp lasts an average of 5,000 to 10,000 burning hours before the intensity decreases. If you use the heater for 5 hours weekly, you will enjoy the same lamp for over 20 years without maintenance. Carbon lamps often reach the 10,000-hour mark, while powerful halogen lamps usually continue to provide effective heat for around 5,000 burning hours.

Can I combine my patio heater with solar panels?

You combine a patio heater perfectly with solar panels to put your own generated electricity to immediate use. By switching on the heater on sunny days or via a home battery, you heat the outdoor space completely CO2-neutrally. This increases your self-consumption of solar energy by an average of 15 percent, which is especially beneficial now that the rules surrounding net metering are changing.
