🧠 Pro tips for choosing

✔️ Heat pumps are generally the best compromise for residential pools in Quebec.
✔️ If you already have a gas connection , natural gas heating can be very efficient.
✔️ Solar is excellent as an ecological secondary system, especially when combined with a heat pump.
✔️ Avoid electric heating alone for large pools — too expensive.
