Why Switch to a Heat Pump?

If you're still heating your hot tub, swim spa or pool with an electric heater, you're paying far more than you need to. Air source heat pumps pull warmth from the ambient air and deliver it into your water — meaning for every 1KW of electricity you use, you can get up to 16KW of heat in return.

At Hortus Collection, we supply and install the UK's most advanced heat pump technology, so you spend less time worrying about energy bills and more time enjoying your hot tub, swim spa or pool.

PRODUCT SPOTLIGHT

Meet the Mr. Silence Range. The world's quietest inverter pool & spa heat pumps

The Aquark Mr. Silence is built around one idea: you shouldn't have to hear your heat pump. Using patented InverPad® technology, it combines a unique airflow design, stepless DC inverter control, and noise-cancelling engineering to run at just 36.5dB(A) — quieter than a normal conversation.It's not just whisper-quiet. It's also remarkably efficient, delivering a COP of up to 16, meaning your hot tub stays warm for a fraction of the running cost of a standard heater. The unit automatically adjusts its speed to match the conditions — running at full power to heat your spa quickly, then easing back to a quiet, efficient hum once temperature is reached.Control it from anywhere with the InverGo Wi-Fi app, and enjoy peace of mind with a full 7-year warranty.Twisted titanium heat exchanger — durable and corrosion-resistant⚡ Voltage-tolerant — works between 180V–260V, protecting against supply fluctuationsCTA: View Mr. Silence Models
