🏊 Pool Sizing Guide – Is This Heat Pump Right for Your Pool?

Recommended Pool Volumes

Pool Coverage	Recommended Volume
Covered Pool (with thermal cover)	95 – 110 m³
Uncovered Pool	70 – 85 m³

💡 Pro Tip: Always use a thermal pool cover to maximize efficiency and reduce heat loss overnight. A good cover can reduce your heating costs by up to 70% and significantly improve heat-up times.

Example Pool Sizes (Approximate)

The PET-30T is ideal for pools such as:

• 10m x 5m x 1.5m depth = 75m³ (uncovered)
• 12m x 5m x 1.5m depth = 90m³ (with cover)
• 10m x 6m x 1.8m depth = 108m³ (with cover)

⏱ Estimated Heat-Up Times

How long will it take to heat my pool? Use this guide to estimate heat-up times for your pool volume and desired temperature increase.

Heat-Up Time Calculator

These estimates are based on the formula:
Time (hours) = (Pool Volume m³ × Temperature Rise °C × 1.16) ÷ Heat Pump kW Rating

Using the PET-30T’s performance at typical UK spring/autumn conditions (15°C air, heating capacity of 21kW):

Pool Volume	5°C Rise	8°C Rise	10°C Rise	15°C Rise
60 m³	16 hours	26 hours	33 hours	50 hours
70 m³	19 hours	31 hours	39 hours	58 hours
80 m³	22 hours	35 hours	44 hours	66 hours
90 m³	25 hours	40 hours	50 hours	74 hours
100 m³	28 hours	44 hours	55 hours	83 hours
110 m³	30 hours	49 hours	61 hours	91 hours

At warmer conditions (28°C air, 30kW capacity):

Pool Volume	5°C Rise	8°C Rise	10°C Rise	15°C Rise
60 m³	12 hours	18 hours	23 hours	35 hours
70 m³	13 hours	21 hours	27 hours	41 hours
80 m³	15 hours	24 hours	31 hours	46 hours
90 m³	17 hours	28 hours	35 hours	52 hours
100 m³	19 hours	31 hours	39 hours	58 hours
110 m³	21 hours	34 hours	43 hours	64 hours

⚠ Important Disclaimer: These are theoretical estimates based on ideal conditions. Actual heat-up times will vary based on:

• Ambient air temperature and humidity
• Wind exposure and weather conditions
• Pool insulation and use of thermal covers
• Initial water temperature
• Heat loss during heating period
• Pool construction materials and location

💰 Running Cost Comparison

See how much you could save compared to alternative heating methods:

Typical Operating Costs (Based on UK Energy Prices)

Assuming electricity at £0.25 per kWh and heating a 90m³ pool by 8°C:

🤔 Frequently Asked Questions

1. What size pool is the PET-30T suitable for?

The PET-30T is designed for pools between 70-110m³, depending on whether you use a thermal cover. For covered pools, it’s ideal for volumes up to 110m³. For uncovered pools, we recommend staying below 85m³ for optimal performance. A typical 10m x 5m x 1.5m deep pool (75m³) is perfect for this unit.

2. Can this heat pump work during cold UK winters?

Yes! The PET-30T is specifically engineered for cold climate performance and continues to heat effectively down to -20°C ambient temperature. However, heating efficiency does decrease in colder conditions (COP drops from 16 at 28°C to around 4.5 at 15°C). For winter use, we strongly recommend using a thermal cover to minimize heat loss and maximize efficiency.

3. How much does it cost to run the PET-30T?

Running costs depend on electricity prices, ambient temperature, and how much heating is required. With a COP of 6-16, for every 1kW of electricity consumed, you get 6-16kW of heat output. At typical UK electricity rates (£0.25/kWh), heating an 80m³ pool by 8°C costs approximately £13-18, compared to £60-80 for an electric resistance heater – saving you up to 75% on heating costs.

4. How quiet is this heat pump in operation?

In Ecosilence mode, the PET-30T operates at just 42dB at 1 meter – quieter than a normal conversation (60dB). Even in maximum Boost mode, noise levels only reach 60dB. The full inverter technology automatically adjusts fan and compressor speeds, ensuring minimal noise disturbance, making it ideal for residential areas and noise-sensitive locations.

5. Do I need three-phase power for this model?

Yes, the PET-30T specifically requires a 380-400V three-phase electrical supply. This is common in commercial settings and some larger residential properties but may require an upgrade if you only have single-phase supply. If you don’t have three-phase power, consider the PET-30 (single-phase version) as an alternative. Always consult a qualified electrician before purchase.

6. Can I use this heat pump with a saltwater chlorination system?

Absolutely! The PET-30T features a titanium heat exchanger which is fully compatible with saltwater chlorination systems. Titanium is highly resistant to corrosion from salt, ensuring long-term reliability and performance. This makes it an excellent choice for modern pool systems using salt chlorinators.

7. How long does it take to heat my pool from cold?

Heat-up time depends on pool volume, ambient temperature, and desired temperature rise. For example, heating a 90m³ pool by 8°C (from 18°C to 26°C) takes approximately 25-40 hours depending on weather conditions. Using the unit in Boost mode with a thermal cover dramatically reduces heating time. See our detailed heat-up tables above for specific scenarios.

8. What maintenance does the PET-30T require?

The PET-30T requires minimal maintenance:

• Monthly: Check and clean the air filter (if accessible)
• Monthly: Remove any debris from around the unit
• Seasonally: Inspect pipe connections for leaks
• Annually: Professional service recommended (refrigerant check, electrical connections, thorough system inspection)
• Winter (if not in use): Drain water from heat exchanger, install winter cover, disconnect power

Regular maintenance ensures optimal performance and extends the unit’s lifespan.

9. Can the PET-30T also cool my pool in summer?

Yes! The PET-30T includes an automatic cooling mode feature. If pool water becomes too warm during hot summer periods, you can switch the unit to cooling mode to reduce water temperature. This is particularly useful for pools in conservatories or hot climates, ensuring comfortable swimming temperatures year-round.

10. What warranty coverage does this unit have?

Warranty coverage varies by retailer and region. The Astral Pool Pro Elyo Touch typically comes with a manufacturer’s warranty covering defects in materials and workmanship. Check with your retailer (Parts4Tubs) for specific warranty terms. Professional installation by qualified technicians is usually required to validate warranty coverage.

11. Can I control the heat pump remotely via smartphone?

Yes! The PET-30T is compatible with the iQBridge RS accessory (sold separately), which connects the heat pump to the Fluidra Connect platform. This allows you to:

• Monitor water temperature remotely
• Adjust settings from your smartphone
• Set heating schedules and timers
• Receive alerts and notifications
• Track energy consumption

The 10m Modbus signal wire is included for connection to the Connect Box.

12. What’s the difference between Boost, Smart, and Ecosilence modes?

Each mode is optimized for different situations:

• 🚀 Boost Mode: Maximum heating power (30kW at optimal conditions). Use when you need rapid heating at season start, after cold periods, or before pool parties. Higher energy consumption but fastest results.
• 🧠 Smart Mode: Automatically adjusts power between Ecosilence and Boost based on the difference between current and target temperatures. Best for everyday use – balances efficiency with performance.
• 🔇 Ecosilence Mode: Minimum power consumption and ultra-quiet operation (42dB). Ideal for overnight heating, maintaining temperature in residential areas, or when energy efficiency is the priority. Perfect for noise-sensitive environments.
