Commercial Heat Pumps

If you want to gain maximum use of your pool services all year round, then a heat pump from Alto Pacific is the perfect solution; offering an unrivalled combination of performance and economy.

Alto Pacific heat pumps have had design input by our own service and support staff to ensure they can be easily serviced and maintained in the future. Alto Pacific’s heat pumps have stainless steel or ABS UV stabilised plastic cabinets to suit the damp, coastal environment of Australia.  Alto Pacific don’t install inferior quality heat pumps that are powder-coated as these are made from mild steel that will rust in a short period of time due to poor powder coating practices in countries of manufacture.

Alto Pacific’s Australian warehouse stocks all major components, including fans, compressors, heat exchangers, etc. In the event of warranty or service repairs Alto Pacific can readily ship replacement parts to our local service agents all over Australia to get your unit up and running as quickly as possible.

Our list of happy clients include Australia Zoo, Maroochydore Aquatic Centre, Tallebudgera Recreation Centre, Tassie Pools and The Queensland Department of Education.

Our clients and team have had input into the design, component selection and construction of the Alto Pacific heat pump range to make them the most reliable heat pump we have ever seen in our 20 years in the pool heating industry.  Alto Pacific undertake a detailed analysis of your pools climatic conditions using software developed at the University of NSW to ensure the correct sized heat pump is specified for your unique requirements. Our installations only use commercial quality hardware, valves and fittings to provide you an extremely reliable heating system.

As a company we have the following capabilities:

  • Heat load reports showing sizing and running costs
  • Pool heating design and configurations
  • Custom heat pump manufacture
  • Heat pump installation and hydraulics
  • Custom duct and basement installations
  • Domestic and commercial solar design and installation
  • Service and repairs to all brands of heat pumps
  • Project management of electrical and hydraulic installations
  1. Alto Pacific’s 90 KW to 250KW heat pumps are top discharge better suited to commercial installations than side discharge units. Exhaust air is mixed by the fans approx. 2 to 3m above the ground resulting in negligible impact on condenser air temperature.
  2. Alto Pacific’s 90 KW to 250 KW heat pumps are tall by design and feature high mount V shaped condenser coils. This design reduces the effect/occurrence of re-entry of cold exhaust air.  Vertical low to the ground condenser coils in poorly designed heat pumps pick up the cold air that has fallen to ground level causing icing of condensers.  NB frost only occurs in nature close to the ground where the air is coldest
  3. All Alto Pacific heat pumps have extremely efficient and effective defrost systems removing the cost of installing duct work on top of outdoor installations.
  4. Alto Pacific heat pumps feature inbuilt intelligent controllers removing the expense for additional external controllers and cabling. The controllers take care of phase protection, surge protection, compressor staging and duty cycle, circulation pump sampling, defrost parameters and cycling, operational timer, temperature differentials etc.
  5. Alto Pacific heat pump controllers also feature master-slave operation to allow a designated master unit to control the slave units. This avoids uneven operating hours of unlinked heat pumps where one unit does all the work and the others rarely turn on.
  6. Altopacific heat pumps have a longer and more comprehensive warranty than most manufacturers. Spare parts are available from Alto Pacific’s Sunshine Coast Head Office.

What to look for in your heat pump?

It is important to be aware of variations between pump outputs and providers.

Some companies make their units appear more powerful by manipulating wet bulb, dry bulb and dew point temperatures by utilising a 24 – 27 degrees air temperature scale A key rule to remember when researching pool-heating pumps is to ask the supplier about the output details. If a supplier cannot tell you the power output during a typical Australian winter temperature, then don’t buy their machine.

At Alto Pacific, we rate the power output of our heat pump units using a 15-degree air temperature scale so that when your heat pump needs to work at it hardest during winter it is up to the task.
