Electric Blanket Running Costs

Electric blanket running costs vary based on factors like wattage, usage time, and local electricity rates. On average, a 100-watt electric blanket used for an hour may cost around 2-3 pence (GBP) in electricity. This is considering the UK's average electricity price of 27p per kWh as of October 2023.

As you can see, electric blankets prove to be cost-effective in terms of energy consumption. These blankets are typically used for limited durations, and this factor contributes significantly to their efficiency in managing energy bills.

Given their brief usage periods, electric blankets don't substantially impact overall energy consumption. They're designed to provide warmth during specific times, such as before bedtime, without drawing continuous high levels of electricity. This focused usage pattern means that while they offer comfort and warmth, they don't significantly alter the overall energy consumption of a household.

Their brief but effective use, coupled with their ability to maintain warmth efficiently after an initial warm-up period, ensures that the impact on energy bills remains notably modest. Users can enjoy the warmth and comfort of an electric blanket without experiencing a considerable spike in their energy costs!

How Much Electricity Does an Electric Blanket use?

Electric blankets are renowned for their ability to provide warmth without consuming excessive amounts of electricity. These devices are generally designed to be low wattage, making them an energy-efficient option for staying comfortably warm during colder periods.

One of the benefits of the Dreamland electric blankets is their quick heat-up time. When initially turned on, they may require full power for a brief period, usually around 5 minutes, to reach the desired temperature. However, after this initial warm-up phase, they often operate efficiently at lower heat settings, thereby utilising a significantly reduced amount of power.

This unique characteristic allows users to maintain a cosy sleeping environment without continuously drawing high levels of electricity. By adjusting the settings to a lower heat level after the initial warm-up, electric blankets effectively conserve energy while still providing the desired level of warmth.

This energy-saving aspect is advantageous, particularly for individuals looking to minimise their energy usage. Electric blankets' ability to quickly warm up and then operate efficiently at lower settings showcases their energy-efficient nature, making them a practical and cost-effective solution for staying comfortably warm during colder weather.

The Different Types of Electric Blankets

Electric blankets come in three main types. Each one is designed to cater to specific preferences and sleeping arrangements:

Electric Underblankets

Electric underblankets are designed to be placed directly on the mattress, extending up to the pillow area. They provide a layer of warmth underneath the sleeper, ensuring a cosy and comfortable night's sleep.

Electric Overblankets

Unlike underblankets, electric overblankets can be placed over the sleeper or inside the duvet cover. They function as a top layer, providing additional warmth and comfort, either independently or in conjunction with a duvet.

Electric Mattress Covers

Electric mattress covers cover the entire mattress. They offer comprehensive heating for the bed, ensuring a warm and comfortable sleeping surface throughout the night.

What Should I Look for When Buying an Electric Blanket?

There are a number of factors you should always look for when buying an electric blanket. These features will help ensure you get an energy-efficient, but most importantly, toasty blanket:

Fast Heat up

A crucial feature to seek in an electric blanket is its ability to quickly heat up. Look for blankets with fast heat-up capabilities, as they efficiently warm up within a short period after being turned on. This feature ensures that you experience quick warmth and comfort without prolonged waiting times.

Low Energy Costs

Choosing an electric blanket that balances warmth and energy efficiency is essential. Consider blankets with lower wattage ratings, as they consume less electricity while providing adequate warmth. Look for energy-saving features such as adjustable heat settings and timers to manage and minimise energy usage, helping you keep your energy costs under control.

Safety Controls

Safety should always be a priority when selecting an electric blanket. Look for safety features like automatic shut-off mechanisms that turn the blanket off after a certain period or temperature control sensors that prevent overheating. Additionally, ensure the blanket meets safety standards and certifications, providing peace of mind while using it during sleep or extended periods.

How can I Keep the Cost of Running an Electric Blanket low?

Electric blankets offer warmth and comfort without significantly impacting energy bills if used wisely. To keep the running costs of your electric blanket at a minimum, consider these tips:

Use of Heat Settings

Use the adjustable heat settings efficiently! Start with a higher setting to warm up the bed, and then reduce the heat to a lower setting for comfortable sleep. Lower settings consume less electricity while maintaining a lovely amount of warmth. The Dreamland Intelliheat technology adjusts to your body temperature. This means you retain the perfect level of heat, without having to worry about the settings. It also ensures an optimal amount of electricity is being used, which keeps your costs down.

Timers and Auto Shut-Off

Take advantage of timers and auto shut-off features. Set timers to ensure the blanket operates only for the desired duration, preventing unnecessary electricity consumption. Auto shut-off mechanisms prevent continuous usage, offering both safety and energy-saving benefits.

Proper Maintenance

Maintain your electric blanket in good condition. Follow manufacturer instructions for care and storage, ensuring longevity and best performance. A well-maintained blanket operates efficiently, reducing the likelihood of increased energy usage due to malfunctions or inefficiencies.

Electric Blanket Running Costs: Final Thoughts

How much does it cost to have an electric blanket on for an hour?

Determining the cost of operating an electric blanket for an hour involves considering the wattage rating of the blanket and the price of electricity per kilowatt-hour (kWh) in your area. For instance, if your electric blanket has a wattage rating of 100 watts (0.1 kW) and the electricity price is 27 pence per kWh, the calculation would be:

  • Cost=0.1kW×1 hour×27 pence/kWh
  • Cost=0.1kW×27 pence
  • Cost=2.7pence

Therefore, running an electric blanket with a wattage of 100 watts for one hour might cost around 2.7 pence based on the given electricity, you can find the Dreamland specific energy costs information.

Is a heated blanket cheaper than heating?

Heated blankets offer targeted warmth, consuming minimal electricity compared to whole-space heating. Their cost-effectiveness varies based on local energy prices, home heating efficiency, and selective usage. While blankets provide personal warmth, efficient home heating might be more cost-effective. Using blankets as a supplement to lower thermostat settings can reduce overall heating expenses. Overall, heated blankets can be cost-effective for targeted warmth during sleep or relaxation, but the choice depends on energy prices, home heating efficiency, and personal comfort preferences.
