Understanding the cost of running a water heater is essential for managing household energy expenses.

What Factors Influence Water Heater Costs?

• Energy Source (Electric, Gas, Solar)
• Capacity (Gallons)
• Energy Efficiency Rating
• Usage Patterns (Daily Hot Water Consumption)
• Local Energy Rates

Step-by-Step Calculation

The cost of running a water heater can be calculated using the following formula:

Cost = (Power Rating in kW) x (Usage Hours) x (Energy Rate) x (Hours in a Month)

Example Calculation

• Power Rating: 3 kW
• Average Usage per Day: 3 Hours
• Energy Rate: $0.12 per kWh

Step 1: Calculate Daily Cost:

Daily Cost = (3 kW) x (3 hours) x ($0.12) = $1.08

Step 2: Calculate Monthly Cost:

Monthly Cost = $1.08 x (30 days) = $32.40
