Inverter heat pumps are the smartest way to warm up your pool — variable-speed compressors deliver precise, energy-efficient heating while using far less power than traditional heaters. Need instant warmth instead? Our gas pool heaters raise the temperature in hours, not days. Every unit below is expertly sized, installed and supported by Aqua Clear — see the full comparison and FAQs below, or contact us for free sizing advice.
Energy-efficient inverter heat pumps and rapid gas heating — expertly sized, installed and supported by Aqua Clear. Keep your pool at the perfect temperature, all year round.
Inverter technology adjusts compressor speed in real time, so you only use the energy you need — dramatically cheaper to run than standard on/off heaters.
No harsh temperature spikes. Variable-speed heating holds your pool at your exact set temperature, quietly and continuously.
Modern inverter heat pumps extract heat from the air even on cool days and perform across a wide range of NZ conditions.
Gas pool heaters raise water temperature in hours, not days — perfect for spas, holiday batches, and impromptu swims.

A heat pump doesn't generate heat — it transfers existing heat from the outside air into your pool water using a refrigeration cycle. Because it moves heat rather than creates it, it delivers 4–6 units of heat for every 1 unit of electricity, making it the most economical way to heat a pool.
Sizing depends on your pool's surface area, volume, desired temperature, whether you use a pool cover, and your local climate. As a rule of thumb, a covered family pool of 40–50 m³ typically suits a 13–17 kW unit. Contact us with your pool dimensions for a free, accurate sizing.
Strongly recommended. A pool cover can reduce heat loss by 50–70% and evaporation by up to 90%, which means smaller heating bills and faster warm-ups. Most manufacturers also require a cover for full warranty efficiency claims.
Running costs vary with pool size, temperature setting and cover use, but inverter models typically cost a fraction of electric or gas element heating — often $1–$3 per day for a covered residential pool in season. Ask us for a running-cost estimate for your setup.
Yes — modern inverter heat pumps operate efficiently even when air temperatures drop, though output gradually reduces in very cold conditions. For colder regions, we can recommend a unit with a suitable operating range, or a hybrid gas + heat pump setup.
With regular servicing, a quality inverter heat pump typically lasts 10–15 years. Keep the coils clear of debris, maintain correct water chemistry, and book an annual check to maximise lifespan and efficiency.
