The Best Swimming Pool Heaters

As a pool heater may be the biggest investment into your pool equipment, you want to ensure you make the right choice and with so many different options on the market it can get confusing. We have created a quick read below outlining the different types of heaters and a few of our favourites.

Key features on most Heaters available these days are:

  • Easy to read LCD display
  • Compact design
  • Very durable
  • Able to heat almost any pool
  • Wifi as a standard

Three main points to consider when choosing a pool heater

  • Costs of purchasing the heater vs operating costs
  • The application, environment and the desired requirements of the heater
  • The frequency in which you will use the pool

Whether you’re putting in a new in-ground pool or simply interested in upgrading your current pool with a state-of-the-art heat pump system, choosing the pool heater that’s going to be best for you depends on a number of different factors. You’ll have to decide if you want to invest a little more money up front for savings in the long run in the form of lower monthly operating costs, or if you want to save money on the initial purchase and installation, you’ll have to be willing to pay a little more each month to operate the heater.

Your location and climate will also be a big factor in deciding what type of pool heater to buy. If you live in a cooler climate that doesn’t get a lot of sunshine, solar pool heaters and electric heat pumps won’t be the best choice.

And finally, one thing that a lot of people fail to consider when making a decision for a pool heater is how often they will be using the pool. This comes into play because this will help determine the needed run times for your pump and to determine which one is best for your requirements.

The big question: Solar Pool Heater, Electric Pool Heater, Gas Heater or Heat Pump?

Without going into much detail, hands down we love our ECO heat pumps because of their longevity, efficiency, safety and ease of use. If you want to get down into the nitty-gritty details, you can check out our very detailed comparison between solar pool heaters, gas heaters, and heat pumps here.

Pool Heat Pump Installation Notes

The total price for Heat Pumps does not include any electrical installation costs and plumbing costs. For the electrical installation, a qualified electrician is required to properly ground the unit and hardwire it into your home’s electrical system. The total costs for electrical installation of the Pool Heat Pumps can run anywhere from $120 - $200 depending on labor costs, location, and materials used for installation.

For the plumbing costs, a trade qualification is not required, but is recommended to ensure that the warranty isn’t voided. Plumbing costs can be anywhere from $100 - $500 depending on the labor costs and the complexity of the plumbing work to be done. If your pool’s plumbing system has enough space to accommodate a pool heat pump without complex plumbing work then it shouldn’t cost too much.

These are just rough approximations of expenses, for a more accurate estimate, contact your local electrician and plumber
