CALOREX INVENTS THE SWIMMING POOL HEAT PUMP

Back in 1974, two engineers in Maldon, England set out to find an economical way to heat a swimming pool. Utilizing refrigeration technology in reverse, they designed and built the first swimming pool heat pump that would heat a pool at the fraction of the cost of conventional gas heaters.


1978 CALOREX BRINGS SWIMMING POOL HEAT PUMP TECHNOLOGY TO THE USA
After some research, Calorex concluded that Florida had 2 things that are essential to this technology, lots of swimming pools and lots of humidity. Originally they built units in England and shipped them here and in 1978 they started manufacturing swimming pool heat pumps in Ft. Myers, Florida, which is where we are located to this day.


1982 CALOREX INTRODUCES THE RX SERIES
The theory of using refrigeration technology for heating swimming pools was sound, however many of the components available were not. The RX series was engineered as a swimming pool heater as opposed to the assembly of “off the shelf components. The RX series had a vinyl clad cabinet to resist rusting and the evaporator had a special coating to eliminate corrosion.


1985 CALOREX INTRODUCES THE “SMART CLOCK” OPTION
Calorex invented a timer that was tied to the heat pump’s thermostat and in the event the pool water temperature dropped below the thermostatic setting on the unit it would override the timeclock, turn on the heat pump and run until the temperature setting was satisfied.


1986 CALOREX INTRODUCES THE “M SERIES”
The “M” series eliminated the metal cabinet and replaced it with fiberglass which eliminated the rust issue. The evaporator was reconfigured and it’s size was increased providing more heat and efficiency.


1990 CALOREX INTEGRATES POOL/SPA HEATER
Calorex incorporated technology that would heat a pool/spa combination with one heater at the touch of a button.



1993 CALOREX BRINGS ON THE M125SHE
This model increased the heating capacity, efficiency and incorporated programmable digital technology for pool/spa heating functions.


1997 CALOREX INTRODUCES THE “PREMIUM SERIES”
This unit was designed with a plastic cabinet, an oversized evaporator and a “Scroll Compressor.” The “Scroll” compressor from Copeland replaced the less reliable, less efficient piston compressor. It increased efficiency and reduced noise from the compressor substantially. Electronic dual pool/spa thermostats were standard features eliminating less reliable analog controls.

2000 CALOREX USA STARTS DOING BUSINESS AS “AQUATHERM”
Back in 1985 Calorex in England spun off Calorex in the USA as a separate company. There was no problem with confusion of the 2 names until both companies put up websites on the Internet. We agreed to start doing business as “AQUATHERM Heat Pumps” which ties into our sister company Aquatherm Industries, America’s largest manufacturer of swimming pool solar systems.


2000 AQUATHERM BRINGS OUT THE “AQUATHERM SERIES 2000”
This re-engineered line combined all the quality features of the “Premium Series” along with total digital technology. Temperature setting accuracy and reliability is greatly enhanced. BTU output and Coefficient of Performance was increased by more than 10%. Automation for pool/spa combinations was built in, eliminating the need for additional expensive external controls. A remote keypad allowed the pool owner to be able to control the pool temperature and pool/spa functions from a convenient location in the house.

2002 AQUATHERM INTRODUCES THE “AT1000D”
In late 2001 Copeland Corporation responded to the needs for more BTU’s in a swimming pool heater. They made a larger ZR80 Scroll compressor specifically for the use in swimming pool heat pumps. This compressor combined with a larger heat exchanger produces the highest BTU output unit we’ve ever built.

2003 Aquatherm Introduces the "Titanium Series"
Over the years the pool heat pump industry has gone through a process of eliminating the weakest link. For years Aquatherm has used and still does use marine grade cupronickel heat exchangers. Properly installed and maintained, there have been relatively few failures over the years. Unfortunately many pool owners do not keep their pool water balanced and that can lead to failure of the heat exchanger. If the heat exchanger is breached and pool water gets in the freon lines, the other two major components, the compressor and evaporator, are compromised as well, in effect ruining the entire machine. The "Titanium Series" utilizes titanium tubing in the heat exchanger which is virtually unaffected by pool water imbalances and carries a 15 year warranty.
