BTU/h Formula:
| From: | To: |
The BTU (British Thermal Unit) calculation for pool heat pumps determines the heating capacity required to raise your pool's temperature by a specific amount within a given time frame. This helps in selecting the appropriately sized heat pump for your swimming pool.
The calculator uses the BTU/h formula:
Where:
Explanation: This formula calculates the BTU per hour required to heat your pool water by multiplying the water volume by temperature difference and the weight of water, then dividing by the desired heating time.
Details: Proper BTU calculation ensures you select a heat pump that can efficiently heat your pool to the desired temperature within your preferred timeframe, preventing undersized or oversized equipment selection.
Tips: Enter pool volume in gallons, desired temperature increase in °F, and the time in hours you want the heating to be completed. All values must be positive numbers.
Q1: What is a BTU in pool heating?
A: BTU (British Thermal Unit) is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
Q2: How do I calculate my pool volume?
A: For rectangular pools: Length × Width × Average Depth × 7.5. For circular pools: π × Radius² × Average Depth × 7.5.
Q3: What is a typical temperature rise for pools?
A: Most pool owners aim for a 10-20°F temperature increase, depending on climate and personal preference.
Q4: How long does it typically take to heat a pool?
A: Most heat pumps can raise pool temperature by 1-2°F per hour under optimal conditions.
Q5: What factors affect heating efficiency?
A: Ambient temperature, humidity, wind speed, pool cover usage, and insulation all impact heating efficiency.
