With the growing popularity of backyard pools, more and more homeowners are exploring efficient ways to extend their swimming seasons. One of the most energy-efficient and effective methods is installing a heat pump. But a common question arises: what size swimming pool heater do I need? Particularly, if you have a 60m³ pool, you'll want to ensure that your pool heat pump is neither underpowered nor overkill.
This article dives deep into the technical and practical considerations for choosing the right heat pump size for a 60m³ pool. We'll explore how to use a pool heat pump sizing calculator, understand COP (Coefficient of Performance), and provide detailed guidance on how to size a pool heater. We'll also answer important questions like how much to heat a pool, how long does it take to heat a pool, and how to heat a swimming pool fast.
By the end, you'll have a comprehensive understanding of heat pump sizing and be equipped with the knowledge to make an informed decision for your pool.
Before diving into sizing, it's essential to understand the concept of COP (Coefficient of Performance), a critical measurement of heat pump efficiency.
COP is a ratio that compares a heat pump's energy output (in terms of heat) to the electrical energy it consumes. For example, a heat pump with a COP of 5 generates 5 units of heat for every 1 unit of electricity used.Why COP Matters for Pool Heating
A higher COP means better energy efficiency.
It directly correlates with how much to heat a pool will cost.
It helps you calculate long-term savings on energy bills.
| COP Rating | Performance | Energy Efficiency |
|---|---|---|
| 3.0 | Moderate | Average |
| 4.0 | Good | Above Average |
| 5.0+ | Excellent | Highly Efficient |
When choosing a heat pump, always ask about its COP rating. Modern models designed for pools typically range from COP 4 to 6, depending on weather conditions and installation quality.
To determine what size swimming pool heater do I need, it's crucial to understand the key variables that affect the required heat pump capacity.
Pool Volume: For a 60m³ pool, that equals 60,000 liters of water.
Desired Temperature Rise: Typically from 15°C to 28°C (~13°C increase).
Heating Timeframe: Do you want to heat the pool fast or gradually?
Climate Zone: Outdoor temperature directly affects how long does it take to heat a pool.
Pool Cover Usage: A cover retains heat and reduces energy consumption.
Wind Exposure: Wind increases heat loss.
Most experts suggest using the following BTU (British Thermal Unit) calculation:
BTU/hr = Pool Volume (liters) × Temperature Rise (°C) × 1.16
So, for a 60m³ (60,000 liters) pool with a 13°C rise:
BTU/hr = 60,000 × 13 × 1.16 = 904,800 BTU
This total is the energy required to heat the pool water.
Since heat pumps are rated in kilowatts (kW), we must convert BTU to kW:
1 kW = 3,412 BTU
904,800 BTU ÷ 3,412 = ~265 kW (total energy needed)
But we don't need all this energy at once. Instead, we choose a heat pump based on how quickly we want to heat the pool.
| Heating Duration | Recommended Heat Pump Size (kW) |
|---|---|
| 1-2 days | 35-40 kW |
| 3-5 days | 20-25 kW |
| 5+ days (maintenance) | 12-18 kW |
So, if you want to heat a swimming pool fast, go for a heat pump with at least 35 kW.
Now that we've established the required capacity, let's talk about how to choose the ideal heat pump for your 60m³ pool.
A pool heat pump sizing calculator is one of the most effective tools for accurately determining the right unit. It takes into account:
Your pool's volume
Average outdoor temperatures
Desired water temperature
Wind and humidity levels
Pool cover usage

High COP models may cost more upfront but save thousands in the long run.
Choose inverter heat pumps for variable speed control and better energy efficiency.
Choose models under 50 dB(A) for quiet operation.
Inverter models are generally quieter.
Go with established brands that offer warranties of 2–5 years.
Check for customer reviews and maintenance support.
| Model | Capacity (kW) | COP | Noise (dB) | Warranty | Price Range |
|---|---|---|---|---|---|
| AquaPro Inverter 35 | 35 kW | 5.6 | 48 dB | 3 Years | $3,200–$3,800 |
| Hayward EnergyLine Pro | 25 kW | 5.2 | 50 dB | 2 Years | $2,500–$3,200 |
| Pentair UltraTemp 30 | 30 kW | 5.8 | 46 dB | 5 Years | $3,800–$4,500 |
| Zodiac ZS500 iQ | 20 kW | 6.0 | 42 dB | 3 Years | $3,000–$3,700 |
Beyond sizing and performance, there are additional considerations that can impact your heat pump's effectiveness and lifespan.
Must be installed outdoors with good airflow.
Requires electrical connection (typically 220–240V).
Proper drainage for condensation.
Clean the evaporator coils regularly.
Check for loose wiring or corrosion.
Inspect and clean filters every 3–6 months.
Optimal performance starts at air temps above 7°C.
Use a pool cover to retain heat during cooler nights.
How much to heat a pool depends on your heat pump's efficiency and electricity rates.
| Heat Pump Size | Monthly Cost (Est.) | With Pool Cover |
|---|---|---|
| 12 kW | $80–$120 | $60–$90 |
| 20 kW | $130–$180 | $100–$140 |
| 35 kW | $180–$250 | $140–$200 |
How long does it take to heat a pool with a heat pump?
| Heat Pump Size | Time to Heat 60m³ Pool by 13°C |
|---|---|
| 12 kW | 5–6 days |
| 20 kW | 3–4 days |
| 35 kW | 1–2 days |
To heat a swimming pool fast, always opt for a higher-capacity heat pump, especially if you live in a cooler climate or don't use a pool cover.
Choosing the right heat pump for your 60m³ pool is essential for efficient, cost-effective water heating. With the right size, you'll not only enjoy a warm pool throughout the year but also minimize operational costs.
To summarize:
Use a heat pump size calculator for accurate sizing.
For a 60m³ pool, a 20–35 kW heat pump is generally ideal.
Consider factors like COP, climate, and pool cover usage.
Higher COP units offer better energy savings.
If you want to heat a swimming pool fast, go for higher capacity units.
Understanding your pool's specific needs and matching them with the right heat pump model ensures optimal performance and a longer swimming season.
