AquaCal® units feature ThermoLink® Titanium Heat Exchangers, allowing us to build the most durable, most cost efficient heat pump with the industry’s strongest warranty to back it up!

At the heart of your heat pump is the patented ThermoLink® Heat Exchanger. The primary cause of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy. This cupronickel material is susceptible to attack from the sanitizers used in pools and spas, and from other related water chemistry conditions. Once the heat exchanger fails, the heat pump is ruined. The ThermoLink® Heat Exchanger tube is made from titanium, and is virtually impervious to water-chemistry damage.

  • Patented counter-flow water management system
  • Heats water faster and more efficiently
  • Impervious to chemical corrosion
  • Durability without sacrificing performance
  • Lifetime limited warranty
Where do Heat Pumps get Installed?

Our Heat Pump Installation Diagram will show you:

The AquaCal® heat pump is installed right into your existing pool-plumbing configuration, after the filter and before a chlorine generator, if you have one.

Now that you are armed with AquaCal® core knowledge, contact your local Pool Professional to size your pool, compute your heating requirements and install the AquaCal® unit that is right for you!

Know the Terminology

Known industry-wide as COP, coefficient of performance is a standard way of measuring the operating efficiency of a unit.

Simply put, the higher the COP, the more efficient the heat pump. For every dollar you spend to heat your pool, you get that dollar… multiplied by the COP… back in ‘dollars worth’ of heat.

This chart illustrates the cost of heating your pool with an AquaCal® Heat Pump compared to other heating methods:

AquaCal® is BY FAR the MOST COST EFFICIENT swimming pool/spa heat pump available anywhere.

AquaCal® heat pumps are easy to own and easy to operate. Your local Pool Professional can specify a unit that is suited to your pool heating needs, being conscious of your budget. The same Pool Professional can install the unit in a single day and you can swim in luxuriously warm pool water in a very short time!

AquaCal® heat pumps are designed with YOU in mind. The functional design is based on simplicity. Our units are configured for easy operation. Simply set it and forget it. The structural design is based on enhancing the efficiency and esthetics of the unit. Built to last and engineered to fit easily into the tightest of spaces, their compact designs blend into every backyard resort decor.

AquaCal® cares about your peace, as well as your peace of mind. Our units are equipped with a super-quiet fan and ‘Scroll™’ compressor technology, instead of pistons, for the quietest operation possible. Now all units are SuperQuiet!

AquaCal® heat pumps are manufactured in the Unites States to the highest quality standard. We have a state-of-the-art manufacturing facility with an advanced on-site testing laboratory. Our highly trained engineers and technicians use sophisticated computers and software to develop leading edge products that keep us at the forefront of the industry. Many AquaCal® units are microprocessor controlled (they have a computer ‘brain’ to control their function) and have Titanium Heat Exchangers with a patented water management systems.

AquaCal® builds heat pumps to last! The ThermoLink® Titanium Heat Exchanger is a high tech, super strong, space-age metal that is impervious to pool chemical corrosion and virtually indestructible. The cabinet is UV protected high-impact plastic, therefore rust and corrosion-proof. All component parts are quality inspected and highly tested to insure suitability and durability under the most severe weather and pool conditions. Count on AquaCal® heat pumps to last nearly twice as long as standard fossil fuel heaters.

AquaCal’s warranty is the very best in the business. The Titanium Heat Exchanger has a limited lifetime coverage. We have been in the same location since 1981, so you know we will be around to back-up our warranty.

Factory Service… not just ‘factory-trained’. AquaCal’s reliability and dependability are legendary in the industry. Our service is performed by AquaCal® FACTORY Service Technicians. The only time you will probably ever meet one of our service technicians is when you enroll in our annual planned maintenance program.

AquaCal® cares about the environment. Employing the most current refrigerant technology and highest efficiency expertise, our units utilize clean energy with no toxic or combustible by-products.

An AquaCal® heat pump is so efficient, it can give you up to $6.00 worth of heat for every $1.00 you spend to run it (that’s a 600% return). Compare this to a gas heater which returns only 70-80 cents for every dollar spent.

Why Heat Your Pool?

Swim Longer, Swim Warmer
Your swimming pool is an investment and you want to maximize that investment. Without heat, pool usage is limited. Your family can exercise, relax, swim and entertain in warm water even when there is a chill in the air. Extend your season and enjoy quality time with your children and the company of friends in the comfort and security of the ‘resort’ in your own backyard!

Why a Heat Pump to Heat Your Pool?

Use Nature’s Free Heat

A heat pump uses nature’s ‘free heat’ from the air to heat your pool water. It applies the same principle used in refrigerators and air conditioners with technology adapted to pools and spas. A heat pump can even pull residual heat from cool air. Electricity is only needed to transfer the heat, not to create it! It is significantly less expensive than gas or electric heating. This makes a heat pump the most economical, safe and trouble-free way to heat your pool.

Why an AquaCal® Heat Pump to Heat Your Pool?

It’s the Best!

AquaCal® is the largest swimming pool heat pump manufacturer in the world and has been making top quality, highly innovative units since 1981. AquaCal® sets the standard for heat pump technology, reliability, and performance. AquaCal’s factory service warranties assure you that we support our product. And we have a heat pump to suit every need and budget.

AquaCal® Heat Pumps are the Most Efficient Way to Heat Your Pool. Why?

It all comes down to the coefficient of performance (C.O.P.), the standard way of measuring the operating efficiency of a unit. Very simply, the higher the C.O.P., the more efficient the heat pump. For every dollar you spend to heat your pool, you get that dollar…multiplied by the C.O.P…back in ‘dollars worth’ of heat.
