Heating a spa represents a significant portion of its energy consumption.

To maintain a pleasant water temperature without causing bills to skyrocket, a dedicated spa heat pump stands out as a high-performance and sustainable solution. Here is why more and more users are making this choice.

How does a spa heat pump work?

A heat pump captures heat from the outside air to transfer it to the spa water.
Rather than producing heat from electricity alone, it harnesses free and available energy, which explains its excellent efficiency.

In practice, 1 kWh consumed can provide 4 to 5 kWh of heat depending on the conditions.
