Heat Pump Size Formula:
From: | To: |
Definition: This calculator estimates the required heat pump size (in kW) for heating a swimming pool based on pool volume and desired temperature rise.
Purpose: It helps pool owners and professionals determine the appropriate heat pump capacity for efficient pool heating.
The calculator uses the formula:
Where:
Explanation: The formula calculates the energy required to heat the given volume of water by the specified temperature difference.
Details: Correct sizing ensures efficient operation, prevents energy waste, and maintains comfortable pool temperatures.
Tips: Enter your pool volume in cubic meters and the desired temperature increase in degrees Celsius. Both values must be > 0.
Q1: How do I calculate my pool volume?
A: For rectangular pools: Length × Width × Average Depth. For circular pools: π × Radius² × Depth.
Q2: What's a typical temperature rise for pools?
A: Common rises are 10-15°C for seasonal heating, but this depends on climate and usage.
Q3: Does this account for heat loss?
A: No, this is the basic calculation. Add 20-30% for heat loss in uncovered pools or windy areas.
Q4: What about pool covers?
A: Covered pools reduce heat loss by 50-70%, allowing for smaller heat pumps.
Q5: How does this relate to BTU ratings?
A: Multiply kW by 3412 to get BTU/hr. Many heat pumps are rated in BTUs.
