1. What is a Pool Heater Cost Calculator?

Definition: This calculator estimates the operating cost of a pool heater based on its capacity, efficiency, and energy price.

Purpose: It helps pool owners and professionals estimate hourly operating costs for budgeting and comparison between different heater types.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Cost — Hourly operating cost (currency)
• BTU — Heater capacity (BTU/hour)
• Efficiency — Heater efficiency rating (0-1)
• Price per BTU — Energy cost (currency/BTU)

Explanation: The heater's BTU output is adjusted for efficiency, then multiplied by the energy cost to determine hourly operating expense.

3. Importance of Pool Heater Cost Calculation

Details: Understanding operating costs helps in selecting the most economical heater and budgeting for seasonal pool heating expenses.

4. Using the Calculator

Tips: Enter the heater's BTU rating, efficiency (default 0.80 for 80% efficient gas heaters), and energy price (default $0.00002/BTU for natural gas). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical efficiency rating?
A: Gas heaters: 0.80-0.85, Heat pumps: 3.0-5.0 COP (convert to efficiency by dividing by 3.412), Electric: 0.95-1.0.

Q2: How do I find my heater's BTU rating?
A: Check the manufacturer's specifications or model number (often includes BTU in thousands).

Q3: Where do I get price per BTU?
A: For gas heaters: divide your gas price per therm by 100,000. For electric: divide price per kWh by 3,412.

Q4: Does this include maintenance costs?
A: No, this only calculates energy consumption costs. Maintenance costs should be considered separately.

Q5: How can I reduce pool heating costs?
A: Use a pool cover, lower thermostat settings, maintain proper filtration, and consider solar heating options.
