Are Infrared Panels Energy Efficient? Cost, Usage & Savings Explained

The electricity consumption of an infrared panel mainly depends on two things: its wattage and how long it runs. Panels used in homes are available in different wattages, such as 300W, 600W, 800W and 1000W.

If you are wondering whether infrared panels are expensive to run, there is no single answer. The actual cost depends on the panel's wattage, how long it operates, the size and insulation of the room, thermostat settings and, most importantly, your electricity price. A well-insulated home with good temperature control can use electricity much more efficiently than a poorly insulated property where heat is constantly being lost.

Understanding Infrared Panel Wattage

In simple terms, wattage tells you how much electrical power a panel uses when it is operating at its rated power.

For example:

• 300W panel = 0.3 kWh for every hour it runs

• 600W panel = 0.6 kWh for every hour it runs

• 800W panel = 0.8 kWh for every hour it runs

• 1000W panel = 1 kWh for every hour it runs

However, you cannot determine your heating cost by looking at wattage alone. How long the panel actually operates also has a direct effect on electricity consumption. A 1000W panel running for one hour will use more electricity than a 500W panel running for the same amount of time.

There is another important point to understand here. A thermostat-controlled infrared panel does not necessarily remain switched on continuously. Once the room reaches the temperature you have selected, the thermostat can switch the heating off. When the room temperature falls again, it can switch the panel back on.

So, when estimating running costs, it is useful to distinguish between the panel's rated wattage and its actual operating time.

How Many kWh Does an Infrared Panel Use?

kWh, or kilowatt-hour, is the unit used to measure electricity consumption. You can estimate how much electricity an infrared panel uses with a simple calculation:

Electricity usage = Panel wattage ÷ 1000 × Operating hours

For example, let's say you have a 600W infrared panel and it runs continuously for 5 hours.

600 ÷ 1000 × 5 = 3 kWh

This means a 600W panel running continuously for five hours would consume approximately 3 kWh of electricity.

Now suppose your electricity price is £0.30 per kWh. The estimated cost would be:

3 kWh × £0.30 = £0.90

So, under this example, running the 600W panel continuously for five hours would cost approximately £0.90.

This is a simple example rather than a prediction of your actual heating bill. In real use, a thermostat may switch the panel off for periods once the desired temperature has been reached, so the actual electricity consumption can be lower than the continuous five-hour calculation.

How Much Does an Infrared Panel Cost to Run? 

The easiest way to understand infrared heating costs is to look at the panel's wattage and how long it actually operates. For the calculations below, we are using an illustrative U.S. residential electricity rate of $0.18 per kWh, which is close to the current national average. Your actual electricity rate may be higher or lower depending on where you live and your utility provider.

If the panel operated continuously, the estimated electricity use and cost would look like this:

These figures give you a simple idea of how panel wattage affects electricity costs. However, they should not be treated as a fixed daily or monthly heating bill. In real-world use, an infrared panel connected to a thermostat may switch off after the room reaches the selected temperature and switch back on when the temperature falls. This means the panel may not operate continuously for the entire period you are using the room.

How Much Does a 600W Infrared Panel Cost Per Day?

Let's take a 600W infrared panel as an example. If it operates for an equivalent of four hours during the day, the calculation would be:

600 ÷ 1000 × 4 = 2.4 kWh

Using an electricity rate of $0.18 per kWh:

2.4 × $0.18 = $0.43 per day

If the same level of usage continued every day for 30 days, the simple estimate would be:

$0.43 × 30 = approximately $12.96 per month

But this does not mean a 600W infrared panel will necessarily add exactly $12.96 to your monthly electricity bill. The actual cost can change considerably depending on how often the panel runs, outdoor temperature, room size, insulation, thermostat settings and heat loss.

For example, if the thermostat keeps the panel switched off for part of those four hours, its actual electricity consumption will be lower. On the other hand, a poorly insulated room may require longer heating periods, increasing the amount of electricity used.

The best way to estimate your own running cost is therefore to use your panel's wattage, your expected operating time and the electricity rate shown on your utility bill.

What Affects Infrared Panel Electricity Consumption?

The panel's wattage is only one part of the picture. Two identical panels installed in different homes can have noticeably different electricity consumption because the rooms themselves are different.

Room Size

A larger room generally requires more heating output than a small room. The amount of heating required also depends on ceiling height, windows, external walls and how well the room retains heat. This is why simply choosing the highest-wattage panel is not necessarily the right approach.

A panel should be appropriately sized for the room rather than selected purely because it has a higher wattage.

Insulation

Insulation can make a significant difference to heating demand. If heat is escaping through walls, windows, doors or the roof, the heating system has to replace that lost heat.

In a well-insulated room, the heat produced by the panel can remain inside for longer. In a poorly insulated room, the panel may need to operate for longer to maintain the desired temperature, increasing electricity consumption.

Thermostat Settings

Your chosen temperature also matters. Setting a room significantly warmer than necessary can increase heating demand, particularly during colder weather. A good thermostat allows you to maintain a comfortable temperature without leaving the panel running unnecessarily.

Operating Time

This is one of the simplest factors to understand: the longer the panel operates, the more electricity it uses.

A 600W panel operating for two hours will use half as much electricity as the same panel operating for four hours, assuming both periods are at their rated power.

Electricity Price

Even if two households use exactly the same amount of electricity, their heating costs can differ if they pay different electricity rates. This is why it is always better to calculate your own estimated running cost using the tariff shown on your electricity bill.

Pros and Cons of Infrared Heating Panels

Infrared heating has several benefits, but it would not be correct to assume that it is the cheapest heating option for every home. It may work very well in one property, while another property may have higher electricity costs.

What Are the Benefits of Infrared Heating Panels?

1. Direct Radiant Heat

One of the main benefits of infrared panels is that they do not rely only on warm air to provide heat. They use infrared radiation to deliver heat directly to people and surfaces around them.

Instead of simply warming the air first, infrared energy is absorbed by surfaces such as walls, floors, furniture and other objects. These surfaces can then contribute to the overall warmth of the room. This creates a different heating experience from systems that primarily circulate warm air.

2. Better Temperature Control

Infrared panels can be used with thermostats and room controls, allowing you to set the temperature of individual rooms according to your needs.

This can be particularly useful if you do not use every room at the same time. For example, you might want the living room to be warmer in the evening while keeping a spare bedroom at a lower temperature when it is not being used.

3. Potential to Reduce Energy Use Through Zoning

The ability to heat different rooms separately is one of the practical advantages of infrared panels. If some rooms are empty for most of the day, you do not necessarily have to keep them at the same temperature as occupied rooms.

Heating can therefore be focused on the areas where people are actually spending time. The potential saving comes from avoiding unnecessary heating, rather than from infrared panels somehow using no electricity.

4. Low Maintenance

Infrared panels do not have as many moving parts as heating systems that use boilers, pumps or fans. Fewer mechanical components generally mean less routine mechanical maintenance.

In normal use, keeping the panel clean and having electrical connections checked when appropriate is usually much simpler than maintaining a more complex heating system. Electrical work should always be handled by a suitably qualified professional where required.

5. Space-Saving Design

Most infrared panels have a slim design, so they take up very little floor space. Depending on the product design, they can be installed on walls or ceilings.

This makes them practical in rooms where floor space is limited. Some panels are also designed as mirrors or decorative panels, which can make them easier to integrate into modern interiors.

6. Quiet Operation

Infrared panels do not need a fan to distribute heat. Because there is no fan moving air around the room, they operate very quietly.

That can make them suitable for bedrooms, home offices and other spaces where you would rather not have the background noise associated with some fan-assisted heating systems.

What Are the Disadvantages of Infrared Heating Panels?

1. Electricity Cost Matters

Infrared panels run on electricity, so their running cost is directly linked to the electricity price you pay. If electricity is expensive and the panel needs to operate for long periods, your heating costs can increase.

This is why it is important to calculate the likely electricity consumption before installation rather than judging the system only by the purchase price of the panels.

2. They Are Not Automatically Cheaper Than Every Heating System

A common misunderstanding is that infrared panels must be the cheapest heating option because they convert electricity into heat efficiently. It is not quite that simple.

Electric resistance heating converts almost all of the electricity it uses into heat. However, technologies such as heat pumps can, under suitable conditions, deliver more heat for each unit of electricity consumed.

Therefore, electrical-to-heat efficiency should not be confused with the lowest possible running cost.

3. Poor Insulation Can Increase Energy Demand

If heat is easily escaping through walls, windows, doors or the roof of your home, no heating system can completely ignore that heat loss. Infrared panels will also need to replace the heat that is continually escaping.

This means a poorly insulated property may require longer heating periods, which can increase electricity consumption and running costs.

4. Correct Panel Placement Is Important

Where an infrared panel is installed affects how effectively radiant heat reaches different parts of the room. Furniture, walls and the overall layout can influence how the heat is experienced.

Therefore, simply buying a panel with the right wattage is not enough. Its position, mounting height and relationship with the room layout should also be considered.

5. Initial Installation Costs

Installing infrared panels can be simpler than installing some other heating systems, but that does not mean there are no installation costs.

A larger property may require multiple panels, thermostats, controls and professional electrical work. The final cost will depend on the number of rooms, the panel types selected and the existing electrical setup.

How Do I Know If I Should Install Infrared Panels in My Home?

If your home has good insulation, sufficient electrical capacity and you want to control the temperature of different rooms separately, infrared panels may be a good option for you. However, do not make your decision based only on the price of the panels. Also consider your home's insulation, room size, heating habits and current electricity price.

Property Insulation

Start by looking at the insulation in your home. Check whether too much heat is escaping through the walls, roof, windows or doors. With good insulation, the heat produced by the panel stays inside the home for longer and the heating system does not need to replace lost heat as frequently.

Room Size

Next, consider the size of each room. Every room has different heating requirements, so panel wattage should be selected accordingly. A low-wattage panel may not provide enough heat for a large or poorly insulated room. On the other hand, installing a much higher-wattage panel than necessary does not automatically make the room more efficient to heat.

Heating Habits

Now think about when you actually use the different rooms in your home. If you do not use the entire house at the same time, there may be little reason to maintain every room at the same temperature throughout the day.

In this situation, the room-by-room control offered by infrared panels can be particularly useful because heating can be focused where it is needed.

Thermostat and Controls

Thermostats and good controls are also important for keeping electricity consumption under control. Once the room reaches the selected temperature, the thermostat can switch the panel off and turn it back on when the temperature falls.

The key is not simply to buy a panel with a certain wattage, but to control when that heating capacity is actually being used.

Electricity Price

Your electricity tariff has a direct effect on running costs. Before installation, estimate how many kWh the panel may use and multiply that figure by your electricity price.

For example:

Daily cost = Wattage ÷ 1000 × Operating hours × Electricity price

This gives you a starting point for comparing infrared heating with your existing heating system.

Existing Heating System

Finally compare infrared panels directly with your existing heating system. Do not make your decision simply because infrared panels convert electricity into heat efficiently and assume they will definitely be cheaper.

It is better to consider installation costs, running costs, maintenance, comfort, room-by-room control and the practical requirements of each system before making the final decision.

How Can I Reduce the Electricity Cost of Infrared Panels?

The easiest way to control infrared heating costs is to avoid heating more space or for longer than necessary. Good insulation, sensible thermostat settings and room-by-room control can all help reduce unnecessary heating demand.

It is also worth checking whether the panel is correctly sized for the room. A suitable panel combined with an effective thermostat can be more practical than simply installing the highest-wattage panel available.

If you are comparing tariffs, make sure you use the actual electricity rate you pay rather than relying on an example price from an online calculator. Even a small difference in the price per kWh can change the monthly running cost.

Frequently Asked Questions

How much electricity does a 600W infrared panel use?

A 600W infrared panel uses approximately 0.6 kWh for every hour it operates at its rated power. If it operated continuously for five hours, it would use approximately 3 kWh. Actual daily consumption may be lower if a thermostat switches the panel off for periods.

How much does a 1000W infrared panel cost to run?

A 1000W infrared panel uses approximately 1 kWh for every hour it operates at full rated power. At an electricity price of $0.30 per kWh, that would be around £0.30 per hour. The actual cost depends on how long the panel operates and the electricity tariff you pay.

Are infrared panels expensive to run?

Infrared panels can be economical in some homes, particularly when the property is well insulated and the heating is carefully controlled. However they use electricity, so running costs depend heavily on your electricity price and actual operating time. They are not automatically cheaper than every other heating system.

Do infrared panels use electricity continuously?

Not necessarily. A thermostat-controlled panel can switch off once the room reaches the selected temperature and switch back on when the temperature falls. Therefore the panel's rated wattage should not automatically be treated as its continuous daily electricity consumption.

Are infrared panels cheaper than electric heaters?

Infrared panels are themselves a form of electric resistance heating, so the electricity consumption depends on their wattage and operating time. Whether they are cheaper to run than another electric heater depends on the heating output, thermostat control, usage pattern and electricity tariff rather than the word "infrared" alone.

Are infrared panels cheaper than heat pumps?

Not necessarily. Heat pumps can deliver more heat per unit of electricity than electric resistance heating under suitable conditions. Infrared panels may still be attractive because they can offer simple installation, room-by-room control and quiet operation, but running costs should be compared based on the actual heating requirement of the property.

Can insulation reduce infrared heating costs?

Yes. Better insulation reduces the amount of heat escaping from the property. When less heat is lost, the heating system generally needs to operate for less time to maintain the desired temperature, which can reduce electricity consumption.
