What Size Heat Pump Do You Need for Your Commercial Pool?

Maintaining a commercial pool isn't just about keeping the water crystal clear and the tiles sparkling like glass. It's also about comfort, reliability, and top-notch swimming all year round. To do this, install a swimming pool heat pump that meets your needs.  Appropriate water temperature can stimulate customer satisfaction and efficiency in operation, regardless of whether one runs a resort, gym, or swim school. This blog will help you select the best heat pump for your swimming pool. Let's jump in!

Why Size Is Important for a Commercial Pool Heat Pump

A heat pump from a swimming pool extracts the heat energy from the air and passes it to the water. Heat pumps are very efficient if they are correctly sized, though. Here is why it is important to pick the right size:

  • Efficiency: An undersized unit will run constantly, driving up energy costs.

  • Performance: An oversized unit may short-cycle (turn on/off frequently), reducing its lifespan.

  • Cost Savings: The right-sized heat pump for swimming pool heating balances power and efficiency, lowering operational expenses.



How to Determine the Right Size Heat Pump for Your Pool

Calculate Your Pool’s Volume

Larger pools require a more powerful heater. Using the Madimack pool heating calculator, commercial pool owners can determine the most suitable unit based on:

  • Pool size

  • Geographic location

  • Whether a pool cover is used

  • Number of months the pool will be heated

This personalised recommendation ensures you're not over- or under-powering your swimming pool heat pump, something that can greatly affect energy costs and water temperature consistency.

Your Swimming Season Length

How many months do you need heating? Our data shows:

  • 5 months (comfort swimming): Smaller units like the 9kW ECO suffice

  • 7 months (extended season): Mid-range 13-16kW models work best

  • 9-12 months (year-round): You'll need powerful options like the 24kW ECO or multiple units

Do You Use a Pool Cover?

This simple choice dramatically affects your heating needs:

  • With cover: Reduce required heater size by 30-40%

  • Without cover: Need larger heating units of around 24kW.

Your Local Climate

Heat pumps work differently in Darwin than in Hobart. Colder climates need more powerful units (add 20-30% capacity). Our Eclipse series performs best in temperatures below 50°F. You can check out our pool heaters and buy as per your location requirements.

Madimack's Recommended Solutions

Your or your customer's swimming habits play a significant role in deciding the right model:

  • Comfort Over Summer (5 months): For short-term seasonal use, the ECO series is ideal. It's energy-efficient and perfect for maintaining pleasant water during the warmer months.

  • Extended Summer (7 months): If your pool sees extended usage into spring or autumn, stepping up to a larger unit in the ECO or ELITE V3 range will provide the additional heating power needed.

  • Devoted Swimmer (9 months): This is where a heat pump truly shows its value. Commercial pools operating most of the year benefit from the higher capacity ELITE V3 or ECLIPSE models, depending on cover usage.

  • All-Year Swimming (12 months): Pools that run year-round, especially without covers, require serious heating performance. The ECLIPSE series with multiple high-capacity units ensures consistent warmth, even in colder climates.

Find Your Pool's Perfect Heating Match
