1. What is an Electric Heater Cost Calculator?

Definition: This calculator estimates the cost of running an electric heater in the UK based on power consumption, usage time, and electricity price.

Purpose: It helps homeowners and businesses estimate their heating expenses and make informed decisions about energy usage.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Cost} = (\text{kW} \times \text{hours}) \times \text{£/kWh} \]

Where:

kW — Power rating of the heater (kilowatts)
hours — Duration of usage (hours)
£/kWh — Electricity price (pounds per kilowatt-hour)

Explanation: The formula multiplies the heater's power by usage time to get total kWh consumed, then multiplies by the electricity rate to get total cost.

3. Importance of Cost Calculation

Details: Understanding heating costs helps with budgeting, comparing different heating options, and identifying potential energy savings.

4. Using the Calculator

Tips: Enter the heater's power rating in kW, usage time in hours, and electricity price (default £0.34/kWh). All values must be > 0.
