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 Wellis Jupiter is a generously proportioned six-person hot tub designed for family evenings and easy entertaining. One full-length lounger and five contoured seats give every bather their own space, while 46 jets — powered by a single 3HP two-speed pump — deliver a strong, targeted massage from shoulders to feet.

Under the cabinet, a Gecko control system manages the 2kW heater and pump, giving reliable, familiar operation. Built-in LED lighting sets the mood after dark, and a water feature adds a gentle visual and audible touch to the bathing experience. An integrated ice bucket keeps drinks within reach without leaving the tub.

Measuring 200 × 200 × 87cm, the Jupiter suits most patios and decked areas. It can be wired for either a 13-amp plug-and-play supply or a 32-amp hardwired connection, so it fits neatly into a range of garden setups.

Includes the pump; siting with clear airflow is arranged at delivery.£3,295+ £1,595
