Choose Heat Pump Model
** This heat pump calculator is for general estimating only. Running costs will vary depending on use, installation, location, and climate.
Individual results may vary.**
The data used in this calculator may change without notice.
Savings are calculated based on replenishing 6°C of heat loss per day using the model's literage, local annual average temperatures, and a holding temperature of 37°C.
Swim spa water temperature is usually held at lower temperatures than 37°C, which will increase the ROI and reduce the payback time. This is not reflected in the calculator.
