There are a TON of heat pump brands being imported into Australia. Some are sold via eBay, Gumtree, or elsewhere. Almost all are cheap, low-quality, imported equipment, and some has no electrical approvals. Besides the poor-quality of these units, support is often non-existent. They are often sold to make a "quick buck."
We cannot Service or Repair the following brands:
Summer Wave, Swimmax, Coasts, SmartHeat, PoolMaster, Pool Cooler, Pool Chiller, Heat pumps from AliExpress, or other unbranded models.
We sell and install Heat Pumps. There is a lot of misinformation about heat pumps and their capabilities. As they're still a fairly new concept in domestic swimming pools and pumps, we'd like to educate a little bit about them. There is absolutely nothing wrong with Heat Pumps, but you must be aware of their capabilities. In the right scenario, they can be an extremely efficient way of heating.
Here are a few Frequently Asked Questions about pool heat pumps:
FAQ - Heat Pump Frequently Asked Questions
How does a Pool or Spa Heat Pump Work?
Heat pumps transfer heat by circulating a refrigerant through a cycle of evaporation and condensation. The compressor pumps the refrigerant between two heat exchanger coils. In one coil, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings.
The refrigerant is then compressed en route to the other coil, where it condenses at high pressure. At this point, it releases the heat it absorbed earlier in the cycle.
Refrigerators and air conditioners are both examples of heat pumps operating only in a Cooling mode. A refrigerator is essentially an insulated box with a heat pump system connected to it. The evaporator coil is located inside the box, usually in the freezer compartment. Heat is absorbed from this location and transferred outside, usually behind or underneath the unit where the condenser coil is located. Similarly, an air conditioner transfers heat from inside a house to the outdoors.
How is Heat Pump Output calculated?
Most manufacturers give a Maximum Theoretical Output based on ideal conditions. Generally they base this on around ~27°C ambient air temperature, with 27°C water temperature. So a 12kW heat pump, outputs ~12kW at 27°C air temperature. The problem is that when the Ambient air temperature drops, so does the Output of the heat pump! Most of them average about 30% less output when the ambient air temperature is around ~15°C. So a 12kW heat pump, with 15°C air, drops down to about 8kW output. As ambient air temperature rises & falls, so does the out put of the heatpump. \
How long should a heat pump take to heat my pool?
Here's a range of heat up times when pools have a cover, and are well insulated. This is only a rough-guide, and is based on extremely good insulation, and ideal conditions. Most pools don't have that, so you can certainly add a bit to these times. We also have a handy Pool Heater Heat-Up Time Calculator on this page. <-- Heat Up Calculator
50,000L pool with 12kW Heat Pump @ 27°C Ambient air = 300 minutes to rise 1°C
50,000L pool with 12kW Heat Pump @ 15°C Ambient air = 445 minutes to rise 1°C
50,000L pool with 24kW Heat Pump @ 27°C Ambient air = 150 minutes to rise 1°C
50,000L pool with 24kW Heat Pump @ 15°C Ambient air = 215 minutes to rise 1°C
30,000L pool with 24kW Heat Pump @ 27°C Ambient air = 90 minutes to rise 1°C
30,000L pool with 24kW Heat Pump @ 15°C Ambient air = 130 minutes to rise 1°C
30,000L pool with 12kW Heat Pump @ 27°C Ambient air = 180 minutes to rise 1°C
30,000L pool with 12kW Heat Pump @ 15°C Ambient air = 265 minutes to rise 1°C
5,000l spa with 12kW Heat Pump @ 27°C Ambient air = 30 minutes to rise 1°C
5,000l spa with 12kW Heat Pump @ 15°C Ambient air = 45 minutes to rise 1°C
1,000l spa with 12kW Heat Pump @ 27°C Ambient air = 6 minutes to rise 1°C
1,000l spa with 12kW Heat Pump @ 15°C Ambient air = 10 minutes to rise 1°C
1,000l spa with 5kW Heat Pump @ 25°C Ambient air = 14 minutes to rise 1°C
1,000l spa with 5kW Heat Pump @ 15°C Ambient air = 20 minutes to rise 1°C
50,000L pool with 350mJ gas heater @ any air temp = 45 minutes to rise 1°C
30,000L pool with 350mJ gas heater @ any air temp = 29 minutes to rise 1°C
5,000l spa with 350mJ gas heater @ any air temp = 4.5 minutes to rise 1°C
1,000l spa with 350mJ gas heater @any air temp= <1 minute to rise 1°C
50,000L pool with 120mJ gas heater @ any air temp = 135 minutes to rise 1°C
30,000L pool with 120mJ gas heater @ any air temp = 82 minutes to rise 1°C
5,000l spa with 120mJ gas heater @ any air temp = 14 minutes to rise 1°C
1,000l spa with 120mJ gas heater @ any air temp = 3 minutes to rise 1°C
As you can see, Ambient Air temperature does not affect a gas heater. And you can't expect a Heat Pump to be fast.
Why does it take so long to heat?
Where & How should it be installed?
Heat Pumps blow off very cold air when heating. This cold air must have the room and ability to be removed from the Heat Pump as best as possible. One of the biggest problems is when an installer encloses a heat pump under a deck, in a room, or builds a wall around it. This causes the heating-ability to drop off dramatically!
It is very common, and popular, to install a heat pump hidden away, such as under a deck. Heat pumps will still work, but this can dramatically reduce it's output.
What Brand Heat Pump Is Best?
Currently we feel the EvoHeat and Astralpool heat pumps are the best available. This not only includes the quality of the heaters themselves, but also the after-sales technical support, and warranty. As heat pumps have become popular, some of the lesser brands have been imported, and the importers have very little information available, with poor support and product knowledge.
We do not recommend cheap imported heat pumps sold on eBay or Gumtree. Spare parts and Warranty availability is atrocians.
Information as a guide only. There are several variables to consider when sizing a heat pump, or setting expectations.
