How Much Does My Heater Cost to Run?

Heating systems are a critical part of our homes, offices, and virtually any indoor space that needs to be kept warm, especially during the colder months. An electric heater, one of the commonly used systems, brings comfort and coziness to our environments.

The question about the cost of running an electric heater often arises among users. In essence, the operating cost is highly influenced by several factors such as energy efficiency, heater size, usage time, and local electricity rates.

Expanding on this concept, an electric heater’s cost encompasses more than just the initial purchase price. Installation, operation, maintenance, and relative costs compared to other heating systems all contribute to the overall expense.

Electric Heater Basics

Essential Components

Electric heaters, by design, are composed of three main elements: a heating element, a thermostat, and a fan. The heating element converts electrical energy into heat energy, the thermostat regulates the temperature, and the fan distributes the warm air.


The operation of an electric heater is straightforward. When turned on, electric current flows through the heating element, heating it up. The heated element then transfers heat to the surrounding air, warming up your space.

Types of Electric Heaters

Electric heaters come in various forms including panel heaters, convection heaters, infrared heaters, and fan heaters. Each type presents its unique features and efficiency levels, thus influencing the running cost.

Electric Heater Costs

Investing in an electric heater goes beyond the initial purchase price. There are several associated costs that, when combined, give a clearer picture of the total expense you can expect when operating this type of heating system. These include the initial purchase price, installation costs, and the ongoing cost of running the heater.

Initial Purchase Price

The upfront cost of an electric heater depends on a few factors:

  • Type: Different types of heaters come at different prices. For instance, fan heaters are usually less expensive than oil-filled radiators or infrared heaters.
  • Brand: Like any other product, the brand can influence the cost. Renowned brands that are known for quality and durability may cost more than lesser-known brands.
  • Features: Advanced features like programmable timers, remote controls, or smart home compatibility can increase the heater’s price. However, these features often contribute to greater energy efficiency and convenience, which can help save on running costs in the long run.

Installation Costs

While many electric heaters are plug-and-play, some types may require professional installation. This is particularly the case for electric wall heaters or baseboard heaters. The cost of professional installation will depend on the complexity of the job and can include:

  • Labor cost: This depends on the time taken for installation and the hourly rate of the technician.
  • Additional materials: Depending on the heater, you might need extra materials like mounting brackets or wiring.
  • Electrical upgrades: In some cases, your existing electrical system may need an upgrade to safely accommodate the heater.

Factors Influencing Cost to Run an Electric Heater

Operating an electric heater incurs a daily cost that adds up to form the bulk of the heater’s lifetime expenditure.

Energy Efficiency

Energy efficiency plays a key role in determining the running cost of an electric heater. A heater’s energy efficiency is its ability to convert electrical energy into heat.

High-efficiency heaters can produce more heat per unit of electricity, reducing running costs. Features like programmable thermostats, energy-saving modes, and automatic temperature control can contribute to a heater’s energy efficiency.

Heater Size

The size or capacity of your electric heater also has a significant impact on running costs.Larger heaters typically consume more electricity, making them costlier to run. However, they are capable of heating larger spaces effectively.

Conversely, smaller heaters use less electricity but are better suited for smaller rooms or personal use.

Usage Time

The amount of time you use your heater each day directly affects the running costs. Running a heater non-stop throughout the day will consume more electricity than using it for just a few hours.

Seasonality also comes into play here. You will probably use your heater more during the colder months, increasing the running costs during this period.

Local Electricity Rates

Electricity rates vary by location and can significantly influence the cost of running an electric heater. If you live in an area with high electricity rates, the cost to run your heater will be higher and vice versa.

Some areas have peak and off-peak electricity rates, which can affect your running costs depending on when you use your heater most.

How to Reduce Heater Running Costs

Regardless of the type of electric heater you use, there are ways to minimize its running costs. These range from adjusting your usage habits to investing in energy-efficient upgrades. By implementing these strategies, you can enjoy a warm, comfortable home without breaking the bank.

Optimize Usage

How and when you use your heater can have a substantial impact on running costs.

  • Limited usage: Rather than leaving the heater on throughout the day, try to use it only when necessary. If you’re not in the room, turn the heater off. It’s more energy-efficient to heat a room for a short period than to maintain a constant temperature all day.
  • Targeted heating: Instead of heating the entire house, consider using the heater in the room where you spend the most time. This approach, often referred to as ‘zone heating’, can lead to substantial energy savings.
  • Thermostat settings: It’s advisable to set your thermostat to the lowest comfortable temperature. For every degree you lower the heat in the 60-70 degree range, you’ll save up to 5% on heating costs.

Energy Efficiency Upgrades

Upgrading your home and heater for energy efficiency can lead to significant savings over time.

  • Energy-efficient heaters: If your current heater is old and inefficient, consider upgrading to a model with a high energy-efficiency rating. Though the upfront cost may be higher, the reduced running costs will pay off in the long run.
  • Insulation: Good insulation reduces heat loss, meaning your heater doesn’t have to work as hard to maintain a comfortable temperature. Insulating your home’s walls, roof, and floors can be an effective way to cut heating costs.
  • Draught-proofing: Draughts let cold air into your home and can make your heater work harder. Seal up any gaps around doors and windows to keep the warm air in and the cold air out.

Regular Maintenance

Keeping your heater well-maintained can ensure it operates at its best efficiency.

  • Cleaning: Dust and debris can hamper your heater’s efficiency. Regular cleaning, particularly of any filters, can keep your heater running smoothly and efficiently.
  • Servicing: Regular professional servicing can help detect and rectify any potential issues before they become serious problems. A well-serviced heater is more likely to operate at peak efficiency.

Electric Heaters Vs. Other Heating Systems

Gas Heating

Gas heaters may have lower running costs than electric heaters but require a gas connection, which may not be available in all locations.

Solar Heating

Solar heating systems use energy from the sun, drastically reducing running costs. However, they require a substantial initial investment.
