Freebies
Included free with this spa
Your free air source heat pump
This spa comes with a free air source heat pump — the most efficient way to keep it warm. Here's what that saves you:
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.
