❓ Frequently Asked Questions (FAQ)

General Operation Questions

Q: What size pool is the PET-08 suitable for? A: The PET-08 is ideally suited for pools between 20,000 – 40,000 litres. For pools at the upper end of this range (35,000-40,000L), expect longer heat-up times and consider whether a larger model might be more suitable. Pool volume calculation: Length (m) × Width (m) × Average Depth (m) × 1,000 = Litres.

Q: How long will it take to heat my pool? A: This depends on several factors including pool size, starting temperature, target temperature, ambient air temperature, and whether you use a pool cover. For a typical 30,000L pool going from 18°C to 25°C (7° rise), expect approximately 29 hours of runtime in Boost mode under good conditions. Using a pool cover can reduce this by 40-70%. See the Heat-Up Time Calculator section above for detailed estimates.

Q: How much will it cost to run? A: At UK average electricity rates (£0.25/kWh), expect daily running costs of approximately £2-£4 for a 30,000L pool at 25°C, depending on weather conditions and operating mode selected. This is approximately 70-85% cheaper than electric heaters and 50-60% cheaper than gas heating. Annual season costs (6 months) typically range from £500-£800 for actively heated pools.

Q: Which operating mode should I use? A: We recommend Boost Mode for initial heat-up (first 2-5 days of season), then Smart Mode for daily automatic operation. Smart Mode intelligently switches between Boost and EcoSilence based on demand. Use EcoSilence Mode if noise is a concern (nighttime) or when just maintaining temperature. The beauty of inverter technology is that Smart Mode handles everything automatically once set.

Q: Does it work in cold weather? A: Yes! The PET-08 is specifically engineered for cold climate operation and works reliably down to -20°C ambient air temperature. It features automatic defrost technology that prevents ice buildup. However, heating capacity does reduce at lower temperatures – this is normal physics for all heat pumps. At 15°C air temperature, capacity drops to 6kW (from 8.5kW at 28°C), and COP drops to 4.5-8 (from 5.8-15).

Q: How quiet is it really? A: The PET-08 is exceptionally quiet. In EcoSilence mode, it produces just 38dB at 1 metre – quieter than a library or a quiet bedroom. At 10 metres away, this drops to an almost inaudible 21dB (softer than leaves rustling). Even in full Boost mode, it only reaches 51dB at 1m – about the volume of a quiet conversation. This makes it one of the quietest heat pumps available and ideal for residential settings.

Installation Questions

Q: Can I install this myself? A: While mechanically capable DIYers can handle the plumbing connections, electrical installation MUST be performed by a qualified electrician for safety and warranty compliance. Heat pump positioning, plumbing, mounting, and testing can be DIY if you’re confident, but electrical work requires certification. We recommend professional installation for optimal performance and peace of mind.

Q: Do I need a bypass kit? A: While not absolutely mandatory, a bypass kit is highly recommended for several important reasons: (1) Easy winterization and drainage, (2) Flow rate adjustment for optimal performance, (3) Isolation for servicing without draining entire system, (4) Protection against valve failures. Bypass kits are available separately and typically cost £60-£120 depending on specification.

Q: How close does it need to be to the pool? A: Closer is better for efficiency. Ideally within 5-10 metres of pool equipment. Longer plumbing runs lose heat and reduce water flow. However, balance this with noise considerations (though the PET-08 is very quiet) and electrical cable length limitations. See the Cable Length Table in specifications for maximum distances by cable size.

Q: What’s the minimum clearance required? A: For proper airflow and efficiency, maintain minimum 2m in front (air intake), 0.5m behind (exhaust), 0.3m on sides, and 1m above. Never enclose or box in a heat pump – it needs free air circulation to operate efficiently. Installing in a restricted space will significantly reduce performance and may cause overheating failures.

Technical & Performance Questions

Q: What is COP and why does it matter? A: COP (Coefficient of Performance) is the ratio of heat energy output to electrical energy input. A COP of 15 means you get 15kW of heating for every 1kW of electricity used – that’s 1,500% efficiency! The PET-08 achieves COP ratings between 4.5-15 depending on air temperature and operating conditions. Higher COP = lower running costs. Traditional electric heaters have a COP of 1 (100% efficient), making heat pumps vastly superior for economics and environmental impact.

Q: Is it compatible with salt water pools? A: Yes, absolutely. The PET-08 features a titanium heat exchanger which is completely compatible with salt water, salt chlorinators, and all common pool chemicals including chlorine, bromine, and mineral systems. Titanium won’t corrode or degrade from salt exposure, unlike copper or stainless steel alternatives.

Q: Can it cool my pool as well as heat it? A: Yes! The PET-08 offers both heating and cooling functions. In hot summer months when your pool exceeds comfortable swimming temperature (>30°C), the reversible refrigerant cycle can cool the water back down. Cooling is particularly useful for pools with solar covers or in conservatories where water can become uncomfortably warm. Cooling capacity and specifications are similar to heating performance but in reverse.

Q: What refrigerant does it use and why? A: The PET-08 uses R32 refrigerant, which is more efficient and environmentally friendly than older R410A refrigerant. R32 has a GWP (Global Warming Potential) of 675 compared to R410A’s GWP of 2,088 – that’s a 67% reduction in environmental impact. R32 also requires less refrigerant charge (0.65kg vs ~1kg), transfers heat more efficiently, and is easier to recycle. It does have mild flammability (A2L classification) requiring qualified F-Gas technicians for servicing.

Maintenance & Warranty Questions

Q: How much maintenance does it need? A: Very minimal! Monthly: Quick visual check and clear any debris (5 minutes). Seasonally: Clean unit, check connections (30 minutes). Annually: Professional service recommended but not mandatory (£100-£150). The PET-08 is designed for reliable, low-maintenance operation. Unlike gas heaters with burners, igniters, and heat exchangers requiring regular cleaning, heat pumps have far fewer wearing parts.

Q: What warranty is included? A: Warranty terms vary by retailer and region. Typically, Astral Pool provides a 2-year manufacturer’s warranty on parts and labor covering manufacturing defects. Some retailers offer extended warranty options up to 5-10 years. Check with your specific supplier for exact warranty terms. IMPORTANT: Warranty may be voided if unit is not installed by qualified personnel, if freeze damage occurs, or if regular maintenance is not performed.

Q: What if something goes wrong? A: The PET-08 features comprehensive error code diagnostics displayed on the LED panel. Most issues are simple fixes: check power supply, water flow, check error code in manual. For complex problems, contact a qualified heat pump technician. The robust construction and proven components mean failures are rare. Common issues are usually external: tripped breakers, restricted water flow, or incorrect settings rather than component failures.

Q: Can I get spare parts easily? A: Yes, as a leading brand, Astral Pool has excellent parts availability throughout the UK and Europe. Common replacement parts (PCB boards, fans, sensors) are typically available within 1-3 days. More specialized components may take 1-2 weeks. Working with an authorized Astral dealer ensures genuine parts and proper support.

Cost & Value Questions

Q: Is a heat pump worth the investment? A: Absolutely, for most pool owners. While initial purchase cost is higher than electric heaters (£1,500-£2,500 vs £500-£800), the operational savings are dramatic. The PET-08 will save £2,000-£3,000 per season compared to electric or gas heating. This means payback period of typically 1-2 seasons, after which it’s pure savings year after year. Plus, extended swimming season, environmental benefits, and increased property value make it a smart investment.

Q: How long will a heat pump last? A: With proper maintenance, a quality heat pump like the PET-08 should provide 12-20 years of reliable service. The titanium heat exchanger can last 20+ years. Compressor lifespan typically 10-15 years. Compare this to electric heaters (5-8 years) or gas heaters (8-12 years), and the long-term value becomes even more compelling. Annual professional servicing extends lifespan significantly.

Q: Should I leave it running all the time or turn it off? A: Best practice: Leave it running on Smart or EcoSilence mode rather than turning on/off frequently. The inverter technology is designed for continuous operation at variable speeds – this is more efficient than repeatedly starting up. However, if pool unused for extended periods (week+), you can turn it off to save energy. Use the timer function (P5/P6) to schedule operation during off-peak electricity hours for maximum savings.
