🔥 Making Waves with Warmth: Why a Pool Heat Pump Is a Game-Changer

If you’ve ever dipped your toes into a chilly pool and wished for just a few more degrees of warmth, you’re not alone. For many pool owners, maintaining the perfect water temperature can feel like chasing sunshine on a cloudy day. That’s where a pool heat pump like the Electroheat MKV comes in—offering a reliable, energy-efficient way to extend your swimming season and elevate your comfort.

🌞 Why Choose a Heat Pump?

Unlike gas or solar heaters, heat pumps work by extracting warmth from the ambient air and transferring it to your pool water. This method is not only efficient but also cost-effective over time. The Electroheat MKV, in particular, is designed to deliver steady, dependable heating with minimal environmental impact.

Key Benefits:

  • Energy Efficiency: Uses ambient air to heat water, reducing electricity consumption.
  • Cost Savings: Lower running costs compared to gas heaters.
  • Extended Swim Season: Enjoy your pool earlier in spring and later into autumn.
  • Consistent Comfort: Maintains a steady temperature without sudden fluctuations.

🛡️ Maximise Efficiency with a Pool Cover

Want to get the most out of your heat pump? A pool cover is essential. Uncovered pools lose 2 to 3 times more heat than covered ones. By reducing evaporation and insulating the water surface, a cover can dramatically cut heating costs and improve performance.

Pro Tip: Cover your pool at night and whenever it’s not in use.

🌡️ Performance in Cooler Weather

The Electroheat MKV operates effectively down to 10°C ambient temperature. While output decreases in cooler conditions, it still provides reliable heating—making it ideal for New Zealand’s variable climate.

📍 Smart Installation Matters

Location is everything. For optimal performance:

  • Install close to your pool pump and filter.
  • Minimise pipe bends to reduce heat loss.
  • Ensure easy access for maintenance.

🏠 Can It Be Enclosed?

Not really. The Electroheat MKV is built for outdoor use. Enclosing it in a shed or garage without proper ventilation can lead to recycled cold air and reduced efficiency. If you must enclose it, mechanical ventilation is a must.

⚙️ What Influences Heating Performance?

Several factors affect how well your heat pump performs:

  • Pool size
  • Desired water temperature
  • Ambient air temperature
  • Use of a pool cover
  • Heater size

⏱️ How Long Will It Run?

Expect 8–12 hours of daily operation, typically aligned with your pool’s filtration cycle. On warmer days, the runtime decreases. While not as fast as gas heaters, the Electroheat MKV is a long-distance runner—delivering consistent warmth with impressive energy savings.

Typical Heating Gains:

  • 10°C–18°C ambient: 3°C to 5.5°C daily increase
  • Above 21°C: ~0.8°C hourly
  • Over 26°C: Up to 1.1°C hourly
