The heat pump size you’ll need depends on the size of your pool, the shape, and your location. Below is a quick reference on heat pump sizing for a rectangular pool.
• 10,000 gallons then you need a 50,000 – 65,000 BTU heat pump
• 15,000 gallons then you need an 85,000 – 110,000 BTU heat pump
• 20,000 gallons then you need an 85,000 – 125,000 BTU heat pump
• 25,000 gallons then you need an 110,000 – 150,000 BTU heat pump
The installation cost of a heat pump pool heater ranges from a low of $3000 to a high of $5,000.
• Note that this number depends on a few factors, including heat pump size, electrical/plumbing work needed, and location
Pool heat pumps offer affordable heating at $50 – $150 per month. The higher number represents peak use. For most pool owners, heating costs will usually stay on the lower end throughout the year.
• On that note, you can easily double the energy efficiency of any heat pump pool heater by simply using a solar cover. The improved heat and water retention your pool gains from using one take a huge load off of the heat pump’s heating duties.
