How to choose a pool heat pump
Choosing a pool heat pump comes down to five things. Here is what to look at, explained simply.
Key Takeaways
- Start with size: match the output in kilowatts to your pool volume in litres
- Check the efficiency (COP) and the running cost, since these decide what you pay over time
- Confirm it runs on your existing power supply, and check the warranty and local service behind it
Choosing a pool heat pump comes down to a handful of things that matter. Get these right and you will end up with a unit that heats your pool comfortably, costs little to run and lasts for years. Here is what to look at.
1. Size it to your pool
This is the most important decision. A heat pump is matched to your pool volume, so the output suits the amount of water you are heating. As a guide, the 17kW suits pools up to 20,000L, the 24kW up to 30,000L, the 35kW up to 60,000L and the 40kW up to 80,000L. If you sit between sizes or want year-round use, size up. O
2. Check the efficiency
Efficiency is measured as COP, the amount of heat you get for each unit of electricity. A higher COP means lower running costs. The CHR AstroMax range runs from COP 16.0 to 20.0, among the highest available in Australia.
3. Look at the running cost
Purchase price is only part of the picture. Ask what a unit costs to run. A CHR 35kW unit runs at around $1 per hour, far less than gas.
4. Confirm the power supply
Check what power the unit needs before you commit. Most AstroMax models run on standard single-phase power, the supply almost every Australian home already has, so there is no electrical upgrade and no gas line to run. If your pool is larger or you want faster heat recovery, the AstroMax 35T and R40 run on three-phase, which is common in commercial sites and newer or larger homes.
5. Check the warranty and service
A heat pump is a long-term purchase, so how it is backed matters. CHR units come with a 5-year parts warranty, a 15-year compressor warranty and a 25-year heat exchanger warranty, plus a 48-hour on-site service guarantee and local support.
Work through those five and you will choose with confidence. To match a unit to your pool, get in touch with our team or browse the AstroMax range.
