Extending the swimming season is one of the most common wishes of pool owners in Quebec. The choice of heating system determines not only the length of your swimming season, but also your operating costs for years to come.
The heat pump: the balance between performance and economy
A heat pump captures heat from the ambient air and transfers it to your pool water. Its coefficient of performance (COP) of 5 to 6 means that for every dollar of electricity consumed, it produces the equivalent of $5 to $6 in heat. It is the most widely used technology in Quebec for residential pools.
Its efficiency, however, depends on the outdoor temperature — when the mercury drops below 10°C (50 °F), the heat pump loses performance. To properly size the unit, a simple rule applies: multiply your pool’s water volume in litres by 1.3 to determine the ideal BTU rating for an inground pool. For a standard pool, the investment ranges from $3,500 to $6,000 for installation, with operating costs of approximately $300 to $500 per season.
Gas heating: fast power
Natural gas or propane systems heat water quickly, regardless of the outside temperature. This is the preferred solution for heating a spa or for homeowners who want to heat their pool quickly before swimming.
However, operating costs are significantly higher. Continuously heating a pool with gas can cost $1,000 to $3,000 per season, depending on frequency of use and fuel prices. Installation costs range from $2,500 to $5,000.
Solar heating: the eco-friendly option
Solar panels for pools use free energy from the sun to heat the water that circulates through a network of collectors, usually installed on the roof. Operating costs are virtually zero, since only the circulation pump consumes electricity.
Performance depends entirely on sunlight. In Quebec, this system extends the season by 2 to 4 weeks in the spring and fall, but does not allow for precise temperature control. The initial investment varies from $3,000 to $7,000 depending on the surface area of the collectors required.
Which system should you choose?
Heat pumps offer the best performance-to-cost ratio for most residential pools in Quebec. Gas is suitable for occasional use requiring rapid heating. Solar energy is an attractive addition for reducing energy bills, particularly when combined with a heat pump. Your choice depends on your installation budget, desired frequency of use, and energy goals. The Piscine Évolution team can analyze your configuration and habits to recommend the solution best suited to your situation.
