Top 10 Pool Heater Review in Canada

Hayward H250FDP

For those living in colder weather and looking for an energy-saving gas pool heater, we strongly recommend the Hayward H250FDP.

The heater features a standard cupro nickel heat exchanger as well as a draft system. Together they stabilize airflow to the combustion chamber at a low and precise rate, eliminating factors that can affect the heater’s performance (such as weather variables). This conserves fuel through energy loss prevention.

One minus factor of this heater is that you have to use it continually to ensure a smooth operation. If not, the machine might take a few starts before it can function normally.

All in all, thanks to all the features mentioned above, this is the best pool heater for energy-efficiency.


  • Less emission
  • Salt water and corrosion resistance
  • Easy operation


  • A bit noisy

Fafco Solar Bear Economy

If you are looking for a cost-effective heater for your home pool, the Fafco is an excellent choice.

This heater can significantly reduce your pool’s operating cost since it runs 100% on solar energy.

So, is it effective?

Yes, it is. The system features a 2” header along with a 4×20″ wide solar collector. With these components, Fafco Solar Bear offers excellent heat transfer without slowing down your pool’s circulation, yielding faster heat. Generally, it can prolong your swimming season from one to two months.

One thing to keep in mind before purchasing this heater: it needs to be stored indoors during winter; otherwise, leaks can occur. Also, it is rather large, so you will need an adequate storage space for it.

In short, this is the best bang for buck pool heater that will save you money on your utility bill in the long run.


  • Easy installation
  • Made of long-lasting material
  • Has an on/off switch


  • Hoses and clamps sold separately

Cjc Water Heater Thermostat

The Cjc Water heater is a perfect choice for a small pool and spa uses. If you want to heat a larger pool, this one is a bit too small and won’t work as well.

The Cjc heater offers a 220V 3kW of coasts thermostat, which can maintain a pre-set temperature level not exceeding 104°F. It also provides consistent heating without any unpleasant cold water patch.

This heater does not have clear installation instructions, so the next best thing is to watch some tutorial videos on Youtube beforehand. However, we still recommend you to get a professional to do the job.


  • Durability
  • Portability
  • Automatic heating


  • Unclear installation instruction

Steinbach Speed Solar Sun 49120

This is another excellent solar pool heater for those who want to keep their pools heated at a minimum cost. The Steinbach 49120 is especially suitable for houses with lawns, as they are easy to move when you need to mow.

For such a reasonable price, the Steinbach heats very effectively,up to 18600 square inches of water content. You can also join multiple mats together for extra heat power.

One reminder before buying this product: don’t use a high power pump, as the water will flow too quickly and no decent heating can be done. Also, if you have a sand filter, you will need a bypass set to regulate water flow for the same reason.


  • More mats can be added for stronger heating power
  • Easy to connect
  • Eco-friendly


  • Takes up place

American Standard 9075120

The American Standard 9075120 is a perfect match for your whirlpool and spa Jacuzzi.

The heater’s T-Heater offers stable and consistent water temperature and prevents the water from overheating. With this heater, you can enjoy long relaxing baths without having cold water patches or cold water altogether.

Should you desire more heating power, you can always connect multiple heaters together. However, if your pool is small, one should do the job.

However, considering its compact size,American Standard 9075120 are the best pool heaters only for small pools and Jacuzzis. For pools with higher volumes, you can check other options on this pool heater review.


  • Easy installation
  • Affordable price
  • Safe T-Heater


  • Need more than one heater for larger tubs

Smart Pool S601 Pool Solar Heaters

The Smart Pool S601 makes a perfect roof solar heater for in-ground pools.

The heater’s Direct Flow System and 124000 square inches of solar panels offer a quick and eco-friendly heating system. Generally, they can raise your water temperature from 6 to 10 degrees Fahrenheit and extend your swimming season for another two to three months, depending on your region.

The Smart Pool S601 is perfectly suited for roof uses, as it features a mounting channel and multiple wind vents, keeping it stable even in windy weather. 

We have noted that the mat does not come with installation instructions. If you are a novice, it would be better to get professional help.


  • Durable
  • Reduces water evaporation
  • Can be mounted vertically


  • Installation kit sold separately 

EcoSmart SMART POOL 27

We believe the EcoSmart SMARTPOOL 27 is the best electric tankless heater on the market for the price.

For such an affordable price, this heater offers excellent heat power. If installed correctly, it can provide a 1 to 1,5 degree F rise per hour and maintain a 7-degree F difference between water coming in and out. As a bonus, it is energy-efficient and can save you big bucks on your utility bill.

The EcoSmart SMARTPOOL 27 also incorporates a digital thermostat control, allowing you to set the temperature precisely how you want it.

Do note that it is best to hire an electrician if you are not familiar with installation jobs despite its straight-forward installation instruction.


  • Easy installation
  • Easy maintenance
  • Compact and affordable


  • Internal plumb a bit noisy

IIS Water Heater Thermostat

If you are looking for a portable pool heater, this is the right fit.

The IIS Water Heater is lightweight compared to other heaters. Its portability makes this machine the best fit for people who are always on-the-go.

Despite its compact design, the IIS packs multiple helpful features, such as Temperature Sensor and an Intelligent Self-checking system, offering users the most convenience. 

You can easily fine-tune the water temperature as you desire with this heater, bringing a much better pool experience. Besides, thanks to the intelligent monitor, there is no need to worry about poor water flow.

As this heater might take several hours (depending on the amount of water), we would recommend some planning ahead. 


  • Simple operation
  • Energy-efficient
  • Durability


  • A bit noisy

SunHeater Pool Heating System

The sun is not always shining, especially during months when you need pool heaters. Under this circumstance, the SunHeater Pool Heating System is your best bet.

This heater will warm your pool gradually, increasing water temperature around 5 degrees F per day. So you will have to plan before setting up your pool. Even in cloudy weather, it can still do a decent job of raising water temperature several degrees higher. 

For the best result, we recommend mounting the system. However, the mounting kit and rack are not included with this unit, so you will have to make a few trips to the closest home improvement retailer. This will add some extra bucks to the bill but is guaranteed to bring a more satisfying result.


  • Above-ground pool accessories included
  • Durable
  • Eco-friendly


  • Mounting rack and kit not included

FibroPool FH 220

This is an optimum heat pump for pools in coastal regions and salt water pools.

This is what coastal weather does to metal. The FibroPool FH220 solves this problem with its 100% titanium exchanger, providing excellent resilience towards salt water and salt air. 

The FibroPool FH 220 features 20,000 Btu/Hr heating capacity and can decently heat up to 7500 gallons of water. It can also be used for hot tubs, Jacuzzis, etc. With this heater, you can enjoy not only athletic swim routines but also relaxing baths. It works best in sunny weather with warmer air.

One thing users have feedback is that condensation of water can occur under the unit in humid areas. However, this is not at all a major problem. 

For the best result, we recommend covering your pool at night to prevent heat loss.


  • Runs quietly
  • Energy-efficient
  • Shuts off when there’s no pump


  • Condensation under the unit in humid areas
