Commercial Pool Heating Sunshine Coast

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 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 and made from mild steel that will rust in a short period due to poor powder coating practices in countries of manufacture.

Alto Pacific’s Australian warehouse stocks all major pool parts and components that range from fans, compressors, heat exchangers and more. In the event of a warranty claim or service repair, 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 includes Australia Zoo, Maroochydore Aquatic Centre, Tallebudgera Recreation Centre, Tassie Pools and The Queensland Department of Education.

Pool Sunshine Coast

The Alto Pacific team and our clients have had a strategic input into the design, component selection and construction of our superior heat pump range to make it is the most reliable heat pump int the 20 years we have been in the pool heating industry.  Our professional team undertakes a detailed analysis of your pools climatic conditions using advanced software developed by the industry experts at the University of NSW. Using this software, we can ensure you have the correct sized heat pump specific to your unique requirements and aquatic needs. 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 manufacturing
  • 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 250 KW heat pumps are top discharge units which are 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 long 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 a ground level causing icing of condensers.  NB frost only occurs in nature close to the ground where the air is most freezing.
  3. All Alto Pacific heat pumps have incredibly efficient and effective defrost systems removing the cost of installing ductwork 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 and temperature differentials.
  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. Alto Pacific 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 essential 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 fundamental 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.
