The Hydro Pro 7.5kW A7 is our most popular heat pump — and for good reason. With a genuine UK 13A plug-and-play design, this energy-efficient unit heats above-ground and smaller in-ground pools without requiring an electrician. Simply connect to your filtration system, plug in, and enjoy warm pool water within hours.
🎯 Perfect For
- Above-ground pools up to 30,000 litres (30m³)
- Small in-ground pools with good insulation
- Frame pools (Intex, Bestway, etc.) 12ft–18ft round or equivalent rectangular
- Seasonal use from April to September (works above 7°C ambient)
💷 Running Costs — Why Heat Pumps Save You Money
Unlike gas or electric heaters, the Hydro Pro A7 delivers 5.6kW of heat for every 1kW of electricity consumed (COP 5.6). That's 80% free energy extracted from the air!
Typical running cost: Approximately £1.50–£2.50 per day to maintain temperature, compared to £15–£25/day for electric heaters. Over a season, you could save £500+ on energy bills.
🔇 Whisper-Quiet Operation
At just 41dB from 10 metres — quieter than a normal conversation — you'll barely notice it running. Your neighbours won't either.
