Other shoppers asked

Where can I find more info on which pump is best for my pool?

You can use AquaCal's free sizing calculator to determine best fit by visiting here:

Why should I consider heating my pool with a heater?

Heating your pool or spa economically is possible with a heat pump. An AquaCal® heat pump can save you up to 80% over propane gas, 50% to 70% over natural gas, and over 600% against electrical resistance heaters commonly found on most spas. That's why thousands of customers choose heaters to heat their pools over alternative types of heaters. A heat pump makes the most sense if you plan on heating your pool, and the most economical heat pumps feature SCROLL compressors. AquaCal’s HeatWave heat pumps were the first to feature SCROLL compressors as their standard.

How does a heat pump work?

A heat pump functions differently from other pool heaters. It extracts heat from the outside air and transfers it to the pool water, without burning energy to create heat. It simply collects solar energy and transfers it to the water.

Why do AquaCal heat pumps cost more than other heaters?

Electric heat pumps initially cost more due to their innovative technology that sets them apart from gas heaters. However, considering the total cost of ownership, an electric heat pump from AquaCal is far cheaper than a traditional gas heater. Thanks to our patented ThermoLink technology, our electric heat pumps can run for as little as $14.70 per month, compared to gas heat pumps that could cost hundreds a month.

How long will it take to heat my pool?

The initial heating time varies based on pool size and air temperature. Once your pool reaches the desired temperature, the run time can be as little as a few hours per day.

Why do people prefer electric heat pumps over gas heaters?

Electric heat pumps are more eco-friendly and efficient, transferring free heat from the air to your pool water with minimal energy consumption. They also tend to have fewer working parts, reducing the likelihood of breakdowns or repairs.

What is AquaCal’s ThermoLink heat exchanger?

AquaCal's ThermoLink technology features a patented titanium heat exchanger that extends the life of your heat pump investment, saving you money. Look for the "Titanium Inside" decal found only in AquaCal heat pumps.

What size pool heat pump is needed for my pool?

Pool heat pump size depends on pool size, desired water temperature, and local climate. Contact us for a free heat pump recommendation that fits your budget.

How long does an AquaCal pool heat pump last?

An AquaCal Heat Pump typically lasts between 12-15 years, depending on the model, pool size, and usage.

Are AquaCal heat pumps reliable?

AquaCal is the largest pool heat pump manufacturer globally, with over 35 years of experience and over 250,000 heat pumps built. We lead in electrical heat pump technology, providing homeowners with efficient pool heating solutions. All our heat pumps are made in the USA, and we offer full service and support.
