Why add an air source heat pump?

The most efficient way to heat a hot tub or swim spa. Ask us about adding one — it pays for itself in running costs:

Up to 75% cheaper to heat
An air source heat pump moves heat rather than making it, so it sips electricity where the built-in heater guzzles it — dramatically lower running costs.
Around 5kW of heat per 1kW used
It draws free warmth from the outside air, delivering roughly four to five times the energy it consumes (a COP of ~4–5).
Warm all year round
Efficient down to low outdoor temperatures, so your spa stays at temperature through autumn and winter, not just the summer.
Quieter and greener
A quiet, weatherproof outdoor unit with a much smaller carbon footprint than heating on the electric element alone.

Pre Loved Hot Tub: This hot tub has had a previous owner, but it has been fully tested and serviced by professionals, ready for its new owner.

The Retreat Pro V1 is a compact four-seat hot tub designed to make everyday relaxation effortless. Twenty hydrotherapy jets are driven by a single 3HP two-speed pump, delivering gentle circulation on low and a more invigorating massage on high whenever you want it.

At the heart of the tub sits a Gecko control system paired with a 2kW heater, keeping the water at your chosen temperature ready for use. The four-seat layout suits couples and small families alike, with no loungers so every bather gets an upright, jet-focused position.

Built-in Bluetooth speakers let you stream your own soundtrack, while LED lighting and water features add atmosphere once the sun goes down. With a footprint of 180 × 160 × 77 cm, the Retreat Pro V1 fits comfortably on a modest patio or decked area, making it a well-rounded spa for smaller outdoor spaces.
