Introduction

Hot water is a necessity in every home, but it often comes with a hefty price tag on our electricity bills. If you’ve noticed a significant increase in your energy consumption after installing an electric boiler, you’re not alone. Many households see their monthly usage jump from 150 kWh to 550 kWh or more. While all electric boilers operate at nearly 100% efficiency in converting energy to heat, there are several steps you can take to reduce your overall hot water costs.

Four Ways to Cut Your Electric Boiler Expenses

Let’s explore four methods to lower your electric boiler costs, ranging from simple, cost-free adjustments to more significant investments:

1. Lower the Water Temperature

The simplest and most cost-effective method is to reduce the water temperature in your boiler. By lowering the temperature from 80°C to 45°C, you can decrease your electricity costs by 3-5%. This works because it reduces the temperature difference between the water in the tank and the surrounding environment, minimizing heat loss.

Important Note: To prevent bacterial growth, remember to raise the temperature to maximum levels for a few hours once a month to sanitize the tank.

Cost: Free

2. Insulate Hot Water Pipes

Insulating the pipes that carry hot water from your boiler to your taps and showers can lead to significant savings. This not only reduces heat loss but also allows you to get hot water faster, potentially reducing water waste. You can expect to save 1-3% on electricity and 1-1.5% on water consumption with this method.

Cost: Up to $10

3. Install Water-Saving Fixtures

One of the most effective ways to reduce hot water costs is to use less water overall. Installing water-saving faucet aerators and low-flow showerheads can provide the same comfort while significantly reducing water usage. This method can save up to 30% on water heating electricity and 25% on water and sewage costs.

Cost: About $25 for a standard apartment

4. Consider a Heat Pump Water Heater

For those ready to make a more substantial investment, heat pump water heaters offer significant energy savings. These specialized boilers use heat pump technology to heat water more efficiently than traditional electric elements. They’re particularly beneficial for:

  • Off-grid homes
  • Areas with high electricity costs
  • Homes with limited electrical capacity

Heat pump water heaters work well in combination with the water-saving measures mentioned above. For more on integrating advanced technologies into your home energy system, read our guide on choosing the right inverter for your setup .

Cost: $1,200 to $3,000 (European 200-liter systems around $2,000)

Conclusion

While technology continues to advance, even simple measures can significantly reduce your electric boiler costs. By implementing these strategies, you can enjoy hot water comfort while keeping your energy bills in check.
