      Features

       

       

      The only heat pump that allows you to maximize the potential savings of a variable speed pump is an AquaCal, which utilizes our patented ThermoLink Heat Exchanger technology with its unique flow characteristics.

       

       

      • Patented hydraulic design adds only 2 PSI at 45 gpm, increasing compatibility with two-speed & variable speed pumps
      • Saves money when using a variable speed pump by reducing the RPM needed to achieve the same flow rate
      • Save money in a single speed pump application by reducing the run time needed to achieve the same turnover rate of the pool

       

       

      Corrosion Proof Cabinet  

      • Louvered side panels protect evaporator coil while ensuring efficient air flow
      • Rust and fade proof
      • Impact resistant
      • Built-in drain pan provides condensate management

       

       

      AquaTop

      • Unique Air Flow Vectoring Top ensures optimal air flow for maximum efficiency
      • World’s ONLY integrated top that protects internal components and prevents debris like leaves and other vegetation from getting inside the heat pump, rotting and becoming acidic
      • Protection provided by the AquaTop allows for an extended 10 year warranty on the evaporator coil

       

       

      Microprocessor Controlled  with Digital Display

      • Weather protected control with full text display provides easy-to-read menu options and unit status
      • Ability to connect to most external controllers for heating and cooling mode
      • Hybrid functionality can initiate a gas heater when an extra boost of heat is needed

       

      PoolSync Ready

      Adjust your heat mode and temperature setting right through your phone in the PoolSync app.

      Great pool heater

      Great company to deal with. Very responsive staff. Heater is very quite

      Very capable heater

      This heater is very powerful and quick, our pool is 23,000 gallons and we can get it to a nice temp in just a few hours.

      The only reason I’m giving this system a 4 star review is because the control panel design is bad.
      It folds into the unit when not in use, but the area is perfect for wasps and other to settle in. You wont know they’re there until you open the panel and are greeted to a wasp home and a nice sting on a the finger.

      Fantastic Heatpump

      This is truly a fantastic heatpump as it's super quiet and heats the pool efficiently. We installed a wifi sync controller as well which is quite handy to control the pump remotely as well. The other thing I want to appreciate is Aquacal's excellent customer service as they sent a technician immediately when we reported an issue. It just turned out that our pump RPM settings were low and the tecnician fixed it after which the pump started to run very well.

      Ravishankar,

      Thank you so much for taking the time to share your positive experience with our Aquacal heat pump! We're thrilled to hear that it's working efficiently and providing the comfort you were looking for. It's great to know that the added convenience of the wifi sync controller has enhanced your experience.

      We also appreciate your kind words about our customer service. Ensuring our customers have a smooth experience is our top priority, and we're delighted to hear that AquaCal's technician promptly addressed and resolved the issue with the pump RPM settings.

      If you ever have more feedback or questions in the future, feel free to reach out. We're here to help!

      It takes about 4 days to heat the pool 57 degrees to 85

      Scott,

      Thank you for the review. We're glad you've got your heat pump connected and working. The initial heat rise taking several days, especially a rise of approx. 30 degrees, is completely normal for any heat pump.

      Heat pumps are designed to maintain temperature and when coupled with a solar cover, or with Lo Chlor Aqua Blanket, can be done quite efficiently and affordably.

      If we can help assist further with any questions or ways to improve your experience, please don't hesitate to reach out to us at any time.

      How A Heat Pump Works

      A heat pump works differently from other pool heaters. Heat is taken from the outside air and transferred to the pool water. This means your heat pump WILL NOT burn energy to create heat. It merely collects solar energy and transfers it to the water. 

      The process looks like this: 

      • A cool liquid refrigerant is passed through the evaporator coil in your AquaCal Heat Pump
      • As this happens, the air is drawn in through the evaporator coil using a fan
      • The heat from the ambient air warms up the liquid refrigerant inside the evaporator coil so it evaporates
      • We now have warm vapor refrigerant that is passed through a compressor and turned into hot vapor refrigerant
      • Pool water passes through the patented ThermoLink titanium heat exchanger system, which takes the heat from the hot refrigerant and transfers it to the pool water
      • Pool water leaves the heat pump and disperses in the pool to heat it up
      • After heating the pool water, the hot refrigerant turns back into cool liquid refrigerant and the process repeats

      This goes on and on, gradually heating up the entirety of your pool.

      AquaCal ThermoLink Heat Exchanger

      The secret to the AqualCal heat pump’s performance lies in our unique ThermoLink technology. This is a patented titanium heat exchanger in our T90, T115, T135 and all HeatWave SuperQuiet models that prevents premature failure extending the life your heat pump investment and saving you money.

      Don’t fall into the trap of buying heat pumps with low initial costs - look for the “Titanium Inside” decal found only in AquaCal heat pumps.
