10 Best Above Ground Pool Heaters 2025 in Canada

The RayPak 105,000 BTU Propane Above Ground Pool Heater is a solid choice if you have an above-ground pool and need a reliable way to warm your water. With its 105,000 BTU rating, it offers strong heating power suitable for medium to larger above-ground pools, helping you enjoy longer swim seasons. This heater is built with quality parts similar to those used in bigger models, which means it’s durable and designed to last for years with proper care.

Installation and maintenance are straightforward but expect to handle standard propane setup and routine servicing yourself or with a professional. However, keep in mind this model isn’t suitable for high-elevation areas (above 2000 feet) and doesn’t meet Low NOx emission standards, so it may not be the best fit if you live in a region with strict environmental regulations.

This heater performs well for pool owners looking for dependable heat output without complicated features, but double-check your local rules and elevation before buying.

The Pentair Master Temp Pool Heater is a natural gas heater designed to warm above-ground pools efficiently. With a heating capacity of 200,000 BTUs, it can handle medium to large pool sizes, making it suitable for many above-ground pool owners looking for reliable heat. Its low NOx emission feature is a plus for those concerned about environmental impact, as it reduces harmful nitrogen oxide emissions compared to older models. The heater’s size and weight mean it requires solid placement but still fits well near pool equipment.

Installation might need professional help due to gas connections and venting requirements, but once set up, it generally demands minimal maintenance aside from routine checks and cleaning. It is a strong choice for moderate to cooler climates where steady heating is needed; however, users in very cold areas might find it less effective without additional insulation or pool covers. Energy efficiency is decent for a gas heater, though natural gas costs can vary by region, which affects running expenses.

This heater is well suited for pool owners who want dependable, fairly quick heating without complicated upkeep, especially if they have access to natural gas and live in climates that don’t require extreme heating power.

The RayPak 150,000 BTU Propane Above Ground Pool Heater is designed for larger above-ground pools and can also work with some inground pools and spas. Its high heating capacity of 150,000 BTUs enables it to warm your pool faster than many competitors, allowing you to enjoy your pool longer throughout the year. This heater is best suited for pools up to a certain size and up to 2000 feet in elevation, making it well-suited for moderate climates but less ideal for high-altitude areas.

The heater features a PolyTuf textured powder coating for durability, helping it resist outdoor wear and tear. Propane heaters like this one heat pools quickly, although propane fuel can be more expensive than electric options, which may result in higher running costs. Installation and maintenance are typical for gas heaters, and professional assistance might be necessary to ensure safe setup. This model has positive customer reviews that indicate reliability and good performance.

If you want a powerful, fast-heating solution for a larger above-ground pool and are comfortable with propane fuel, the RayPak 156A is a solid choice. For those looking for a more energy-efficient or low-maintenance option, or who have a smaller pool, other models might be more suitable.
