Electric Boiler Energy Calculator (Cost and kWh Usage)

Electric boilers are often touted as an efficient and cost-effective alternative to traditional gas boilers. They are particularly popular in areas where gas is not readily available or as a backup source of heating during power outages. However, before investing in an electric boiler, it is important to understand the energy consumption and costs associated with using this appliance.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

Electric boilers are rated in kilowatts (kW), which indicate the amount of power they consume in one hour of operation. For instance, a 4 kW electric boiler will use 4 kilowatt-hours (kWh) of electricity in one hour of operation. The energy consumption of an electric boiler can be calculated by multiplying the power rating (in kW) by the number of hours of use.

For example, a 4 kW electric boiler used for 6 hours per day will consume 24 kWh of electricity per day (4 kW x 6 hours). Over a 30-day month, this amounts to 720 kWh of electricity (24 kWh x 30 days).

Importance and Relevance Today

Electric boilers are becoming increasingly relevant in today’s world as more people look for ways to move away from traditional fossil fuels. They are particularly popular in areas with access to renewable energy sources, such as solar or wind power, which can be used to generate electricity to power the boiler.

Additionally, electric boilers do not produce any harmful emissions, making them a safer and more environmentally friendly option.

Cost in Dollars of Energy Usage

The cost of using an electric boiler will depend on the energy price in your area. In this article, we will use the default energy price of $0.12/kWh.

To calculate the cost of using an electric boiler, multiply the energy consumption in kWh by the energy price.

For example, using the figures above, the cost of running a 4 kW electric boiler for 6 hours per day for one month would be:

720 kWh x $0.12/kWh = $86.40

Over a year, this would amount to:

720 kWh x $0.12/kWh x 12 = $1,036.80

Money Saving Tips

Although electric boilers can be more expensive to run than gas boilers, there are several ways to reduce their energy consumption and save money on your energy bills.

  • Use the boiler’s timer to ensure it only operates during times when hot water or heating is needed.
  • Keep the boiler well-maintained to ensure it operates at maximum efficiency.
  • Insulate your home to reduce heat loss and make the boiler’s job easier.
  • Consider switching to a different energy tariff which may offer cheaper rates during off-peak hours.
  • Install a smart thermostat to control the temperature of your home and reduce energy wastage.

By following these tips, you can significantly reduce your energy consumption and save money on your energy bills.

In conclusion, electric boilers are an efficient and eco-friendly option for heating and hot water. Understanding the energy consumption and costs associated with using them is important in order to make an informed decision about whether they are the right choice for your home. By following simple money saving tips, you can reduce your energy bills and make the most of this innovative heating solution.
