Pool Heating Cost Calculator - Daily Fuel & Electric Expense

Estimate how much it costs to heat your pool with gas, propane, or electric heat pumps. Calculate daily running costs based on local utility rates.

Fuel vs. Efficiency

Not all heaters are created equal. Natural Gas and Propane heaters are incredibly fast but have higher running costs. Electric Heat Pumps are slower but can be **3-5 times more efficient** than gas, as they move heat from the air rather than creating it.

Pro Tip: Want to lower these costs by 70%? Use a Solar Cover. It keeps the heat you've already paid for from escaping at night.

Actionable Steps

Typical Energy Values

  • Natural Gas: 1 Therm = 100,000 BTU.
  • Propane: 1 Gallon = 91,500 BTU.
  • Electricity: 1 kWh = 3,412 BTU (Resistance) or ~14,000 BTU (Heat Pump).

Frequently Asked Questions

Which is the cheapest way to heat?

In most regions, an Electric Heat Pump is the most cost-effective long-term solution. While the initial purchase is higher, the daily running cost is often 3-4x lower than propane or natural gas.

Does humidity affect my heating cost?

Yes, specifically for heat pumps. Heat pumps work much better in humid air because water vapor holds more thermal energy than dry air.
