How much electricity does a 2kW heater use?

A 2kW heater uses 2000 watts per hour. To convert watts to Kilowatts, you’ll need to divide the Watts (W) value by 1000.

How to use this calculator

Power consumption (watts) – This field is pre-filled with 2000 watts since 2kW is equal to 2000 watts.

kWh cost (Pence) – Enter how much you pay per kWh in pence. If you pay 29p per kWh, enter 29 – not 0.29.

Usage time (Hours) – Enter the number of hours you plan to use the heater. If you need to enter 15, 30, or 45 minutes, it will be 0.25, 0.50, and 0.75 respectively.

Number of Days (Optional) – Use this option to calculate the running cost per day, month, or year e.g if you want to know how much the 2 kW heater would cost to run per month, enter 30 in the days field.

How to calculate the running cost of a 2 kW heater

Electricity cost calculator

Here’s a step-by-step breakdown of how to calculate the electricity running cost for a 2 kW heater:

Step 1: Determine the wattage of your heater

The first step is to determine the wattage of your heater. This information can usually be found on the label of the heater or in the user manual. In this case, we know that our heater has a wattage of 2 kW (2000 watts).

Step 2: Find out your electricity cost per kWh

The next step is to find out how much you are charged for each kilowatt-hour (kWh) of electricity. This information can usually be found on your electricity bill or you can contact your electricity provider for this information.

Step 3: Calculate the hourly cost

To calculate the hourly cost, we simply multiply the wattage of our heater by the cost per kWh. In this case, it would be 2 kW x [electricity cost per kWh]. For example, if the cost per kWh is £0.29, then the hourly cost would be 2 kW x £0.29 = £0.58.

Step 4: Determine the daily, weekly, monthly, and yearly costs

To determine the daily cost, we multiply the hourly cost by the number of hours we use our heater in a day. For example, if we use our heater for 4 hours a day, the daily cost would be £0.58 x 4 = £2.32.

  • To determine the weekly cost, multiply the daily cost by 7 (days in a week). In this case, it would be £2.32 x 7 = £16.24.
  • To determine the monthly cost, multiply the daily cost by 30 (days in a month). In this case, it would be £2.32 x 30 = £69.60.
  • To calculate the yearly cost, multiply the daily cost by 365 (days in a year). In this case, it would be £2.32 x 365 = £846.80.

Keep in mind:

It’s important to note that the calculations above are based on continuous use of the heater. However, most people do not leave their heaters on for an entire day or month. It’s recommended to factor in usage patterns and adjust the calculations accordingly.
