🏊 Pool Sizing & Heat-Up Time Guide

Is This Heat Pump Right for Your Pool?

The Inverter+ 10.5kW (IPHR26) is ideally suited for medium-sized pools between 25-45m³ (22,000-39,600 liters or 5,800-10,400 gallons). Proper sizing ensures the system operates predominantly at lower, more efficient speeds – maximizing energy savings and minimizing noise.

Estimated Heat-Up Times ⏱

Important Disclaimer: The following heat-up estimates are theoretical calculations based on ideal conditions including: covered pool with isothermal cover, filtration running 15+ hours daily, minimal wind exposure, and no heat loss. Actual times will vary based on ambient temperature, humidity, wind, sun exposure, pool insulation, and cover quality.

Heat-Up Time Calculator @ Air 15°C (7.3kW Heating Capacity)

Pool Size	Temperature Rise 5°C	Temperature Rise 10°C	Temperature Rise 15°C
25 m³	~20 hours	~40 hours	~60 hours
30 m³	~24 hours	~48 hours	~72 hours
35 m³	~28 hours	~56 hours	~84 hours
40 m³	~32 hours	~64 hours	~96 hours
45 m³	~36 hours	~72 hours	~108 hours

Formula Used: Time (hours) = (Pool Volume m³ × Temperature Rise °C × 1.16) ÷ Heating Capacity kW

Heat-Up Time Calculator @ Air 28°C (11.1kW Heating Capacity)

Pool Size	Temperature Rise 5°C	Temperature Rise 10°C	Temperature Rise 15°C
25 m³	~13 hours	~26 hours	~39 hours
30 m³	~16 hours	~31 hours	~47 hours
35 m³	~18 hours	~37 hours	~55 hours
40 m³	~21 hours	~42 hours	~63 hours
45 m³	~24 hours	~47 hours	~71 hours

💡 Practical Tip: For initial season heating, the Inverter+ operates at 100% capacity for faster heat-up. Once your target temperature is reached, it automatically reduces to ~50% capacity for efficient maintenance heating.

🌡️ Seasonal Performance Expectations

Spring (10-15°C Ambient)

Expected Heating Capacity: 5.5-7.3 kW Typical Daily Runtime: 6-12 hours for maintenance Efficiency: Good – System operates efficiently with extended runtime

Summer (20-28°C Ambient)

Expected Heating Capacity: 9.0-11.1 kW Typical Daily Runtime: 2-6 hours for maintenance Efficiency: Excellent – Peak performance with minimal runtime required

Autumn (10-18°C Ambient)

Expected Heating Capacity: 5.5-8.0 kW Typical Daily Runtime: 8-14 hours for maintenance Efficiency: Good – System may run longer as temperatures drop

Extended Season Use (-10 to 10°C Ambient)

Expected Heating Capacity: Reduced (3.0-5.5 kW) Typical Daily Runtime: May run continuously Efficiency: Moderate – Unit operates but with reduced efficiency; anti-freeze protection active

⚠ Winter Operation Warning: When operating below 2°C, continuous water flow is essential to prevent freeze damage to the titanium heat exchanger.

💰 Running Cost Comparison

Why Inverter+ Technology Saves You Money

Traditional heat pumps run at fixed speeds – either full power or off. The Inverter+ adjusts its output continuously, typically running at 20-80% capacity during maintenance heating. This variable-speed operation delivers substantial savings.

Estimated Annual Running Costs (Compared to Alternatives)

Assumptions: 35m³ pool, heated April-September (6 months), maintaining 28°C water temperature, UK energy rates

Heating Method	Estimated Annual Cost	CO₂ Emissions	Notes
Gas Boiler	£1,800-2,400	Very High	Fast heating but expensive to run
Electric Resistance Heater	£2,500-3,500	High	Extremely expensive, 1:1 efficiency
Standard Heat Pump (Fixed Speed)	£600-900	Low	Good efficiency but higher costs
Inverter+ Heat Pump (IPHR26)	£300-450	Very Low	Up to 50% savings vs. standard heat pumps

C.O.P Advantage: At 50% capacity, the IPHR26 achieves a C.O.P of 11.7 – meaning for every 1 kW of electricity consumed, you get 11.7 kW of heating. This exceptional efficiency translates directly to lower bills.

❓ Frequently Asked Questions

Q: How long will it take to heat my 30m³ pool from 15°C to 25°C? A: Under typical spring conditions (air temp 15°C), expect approximately 48 hours for a 10°C rise. With warmer ambient temperatures (25°C+), this could reduce to around 30 hours. Using a quality pool cover significantly improves heat-up speed by preventing overnight heat loss.

---

Q: Can I run the heat pump year-round in the UK? A: Yes, the IPHR26 operates down to -10°C ambient temperature. However, efficiency reduces significantly below 10°C, and running costs increase. For extended season use (October-March), ensure the filtration system runs continuously to prevent freeze damage, and consider whether the higher running costs justify the extended swimming season.

---

Q: How quiet is “ultra-quiet” in practical terms? A: At 10 meters distance during maintenance heating (Silence mode), the IPHR26 produces around 18.6 dB(A) – quieter than a whisper (30 dB) and comparable to rustling leaves. Most homeowners report not hearing the unit from inside their house, even with windows open. During initial heating at full power, noise levels reach approximately 49.9 dB(A) at 1 meter, similar to light rainfall.

---

Q: What’s the difference between Smart Mode and Silence Mode? A: Smart Mode allows the unit to operate at 20-100% capacity, providing fastest heating and intelligent optimization. Silence Mode caps operation at 20-80% capacity and runs approximately 3 dB(A) quieter – ideal for nighttime heating or noise-sensitive environments. We recommend Smart Mode for initial season heating, then switching to Silence Mode for overnight maintenance.

---

Q: How much does it cost to run per day? A: During maintenance heating in summer (once your pool is at temperature), expect approximately £1.50-3.00 per day based on current UK electricity rates (£0.28/kWh average). Actual costs vary with ambient temperature, pool insulation, cover usage, and your target temperature. The Inverter+ technology typically costs 40-50% less to run than conventional fixed-speed heat pumps.

---

Q: Do I need a pool cover? A: While not mandatory, a quality isothermal pool cover is highly recommended. Covers prevent 70-90% of overnight heat loss, dramatically reducing running costs and heat-up times. Without a cover, expect heating times to increase by 2-3× and daily running costs to double. The savings from reduced energy consumption typically pay for a cover within one season.

---

Q: What size pool can this unit effectively heat? A: The IPHR26 is optimized for 25-45m³ pools (5,800-10,400 gallons). You can heat slightly larger pools, but heat-up times increase and the unit may run longer at higher capacity. For pools below 25m³, consider the smaller IPHR20 model for better efficiency. For pools above 45m³, the IPHR33 (13.8kW) would be more appropriate.

---

Q: Is the WiFi control reliable? What if my internet goes down? A: The WiFi system is highly reliable and connects via your home 2.4GHz network. If internet connectivity is lost, the heat pump continues operating with its last programmed settings – you simply lose remote monitoring/control until connectivity is restored. The unit can also be operated manually via the control panel at any time.

---

Q: How does the titanium heat exchanger benefit me? A: Titanium offers exceptional resistance to corrosion from pool chemicals (chlorine, bromine) and salt water. Unlike copper or steel exchangers that can corrode over time, titanium maintains optimal heat transfer efficiency throughout the unit’s lifespan. This translates to longer service life, consistent performance, and lower maintenance costs.

---

Q: Can this heat pump also cool my pool? A: No, the IPHR26 is a heating-only model. Some heat pump models offer reversible cooling/heating, but this unit is optimized specifically for heating performance and efficiency.

---

Q: What maintenance does the heat pump require? A: Maintenance is minimal. We recommend annual professional servicing to check electrical connections, refrigerant levels, and clean the evaporator coil. You should periodically check that the air inlet/outlet aren’t blocked by leaves or debris, and ensure water flow remains adequate. At season end, drain the heat exchanger completely if winterizing. Detailed maintenance procedures are in the installation manual.

---

Q: How long is the warranty? A: Warranty terms vary by retailer. Please contact us directly for specific warranty information on this model, or consult your invoice/purchase documentation.

---

Q: Can I install this heat pump myself? A: No, professional installation by a qualified HVAC technician or pool equipment installer is mandatory. Installation involves electrical work that must comply with local building codes, refrigerant handling (if required), and proper setup of water flow parameters. Improper installation voids warranty and can damage the unit or create safety hazards.
