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

Two 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

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.

The big question: Gas Heater or Heat Pump?

The two main choices when it comes to quick, efficient heating. Both options come with considerable price tags, and the right heater for the right application can either make or break the bank.

Gas heaters are renown for their instant heat, with most pools being warmer within hours, and spas within minutes compared to heat pumps. Gas heater also perform well in ALL environments and all temperatures (ensuring it is correctly sized!)

Heat pumps are more like the long-distance marathon runners of the heater race, they are incredibly energy efficient at maintaining a constant water temperature and can deliver savings of up to 70% versus a gas heater over the heating period.

They are very efficient as they utilize the heat from the surrounding air to heat the pool's water versus burning natural gas or LPG which adds up, quick!

Thus, meaning heat pumps work well in warmer climates but struggle in colder climates. At these lower temperatures a heat pump is likely not the best option for heating your pool as there would be no efficiency in it running for longer periods to reach that desired level.

Below we have outlined the range of heaters currently on the market with our pick at the end!

Madimack Installation Notes

Pool Heat Pump Installation Notes

The total price of the Madimack Pool Heat Pump 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 Madimack Pool Heat Pump 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
