Electric patio heaters are a great way to stay warm while enjoying your outdoor space, but how much do they cost to run? Knowing the costs can help you plan and manage your energy bills effectively.

This article will explain the main factors that affect running costs, such as the heater’s power and electricity prices. It will also share tips to help you save money while staying cosy outdoors.

Keep reading to learn how much it costs to run an electric outdoor heater in the UK and how to use it efficiently. Whether you’re buying a new heater or already have one, this guide will help you make the most of your electric outdoor heating.

Factors Affecting Running Costs

Wattage and Power Consumption of the Heater

The wattage of your electric patio heater plays a big role in running costs. Higher-wattage heaters consume more energy, which means higher expenses. For example, a 600W heater will cost less to run than a 2000W model.

Always check the wattage to estimate energy consumption and choose a heater that meets your needs without unnecessary power usage.

Electricity Rates in the UK

Electricity rates significantly impact running costs. In the UK, the current average price is 34p per kWh. This means a 2kW heater costs approximately 68p per hour. Monitoring energy tariffs can help manage costs effectively.

Duration and Frequency of Usage

How often and how long you use your patio heater directly affects costs. Frequent or prolonged use will quickly add up. Limiting heater usage to when it’s essential or using timers can help reduce expenses.

Environmental Factors

Outdoor temperature, wind, and insulation all influence running costs. Colder conditions or exposed areas require more energy to maintain warmth. Placing the heater in a sheltered spot or using patio covers can improve efficiency and lower costs.

Typical Running Costs of Electric Patio Heaters

Cost Estimates by Wattage

The cost to run an electric patio heater depends on its wattage. A 600W heater costs around £0.20 per hour, making it the most economical option for small spaces. A 2000W heater costs approximately £0.68 per hour, ideal for medium areas.

For larger spaces, a 3000W heater costs between £0.60 and £0.90 per hour, depending on the settings and usage.

Low-Powered Models (1kW – 1.5kW)

Low-powered heaters cost between £0.34 and £0.51 per hour to run. These are best suited for small outdoor areas or close-range heating, offering affordable warmth without excessive energy usage.

Medium-Powered Models (2kW – 2.5kW)

Medium-powered heaters cost about £0.68 to £0.85 per hour. They are perfect for average-sized patios or garden spaces where consistent and moderate heat is needed, balancing cost and performance.

High-Powered Models (3kW and above)

High-powered heaters cost £0.90 to £1.00 per hour to operate. These are ideal for larger outdoor areas or commercial spaces, providing robust heat output for larger gatherings or open, exposed environments (1).

Cost Comparison with Gas Patio Heaters

Electric patio heaters are generally more cost-effective than gas heaters when considering hourly running costs. Electric models cost between £0.20 and £1.00 per hour, while gas heaters typically range from £0.60 to £2.00 per hour, depending on the fuel type.

Gas heaters also require regular refilling of gas canisters, adding to their ongoing expenses. On the other hand, electric heaters need less maintenance as there are no gas tanks to refill or burners to clean.

Gas heaters provide stronger heat, but their higher costs and upkeep make electric options more practical for many homes.

Frequently Asked Questions

How Do I Calculate My Heater’s Running Cost?

To calculate your heater's running cost, multiply its power (in kilowatts) by the electricity rate (in pence per kWh) and the usage duration (in hours). For example, a 2kW heater used for 1 hour at 34p per kWh would cost 68p.

This simple formula helps you estimate costs based on your specific heater and electricity tariff. Adjust for different wattages or usage patterns to get a more accurate estimate.

Does an Infrared Heater Use a Lot of Electricity?

Infrared heaters are energy-efficient and typically use less electricity compared to traditional heaters. They provide targeted heat, reducing overall energy consumption.

While their wattage varies, most models are designed to deliver effective warmth without driving up energy costs significantly.

Are Fire Pits More Cost-Effective Than Electric Patio Heaters for Outdoor Heating?

Fire pits can be cost-effective for occasional use, as they rely on wood or gas, which may be cheaper than electricity in some cases. However, they require ongoing fuel purchases and are less efficient in retaining heat than electric patio heaters.

For regular use, electric heaters are often more economical and environmentally friendly.

Are Electric Patio Heaters Expensive to Maintain?

Electric patio heaters are generally low-maintenance compared to other heating options. They don’t require gas canisters or regular servicing of complex parts, which reduces upkeep costs.

Regular cleaning to remove dust and ensuring proper storage when not in use are the main maintenance tasks. With fewer components to manage, electric patio heaters are a cost-effective and hassle-free choice for outdoor heating.

Conclusion

Electric patio heating offers a convenient and efficient way to enjoy outdoor spaces year-round. By understanding the factors that affect running costs and choosing energy-efficient options, you can keep expenses manageable.

Whether comparing it to gas heaters or exploring cost-saving tips, electric patio heaters provide a practical and reliable solution for outdoor comfort.
