The EcoZone™ Insulation system, featured in every British Hot Tub™, is designed to keep running costs low so you can enjoy your hot tub year-round without worrying about high energy bills. This advanced three-layer insulation provides exceptional heat retention, reduces noise from vibrations, and protects vital components.

1. Cabinet Insulation: The cabinet frame is lined with 1-inch polyurethane foam panels with a reflective foil face, inspired by NASA technology. This flexible, water-resistant material is rot-proof, rodent-proof, fireproof, odor-resistant, and retains 99% of heat within the cabinet.
2. Shell Insulation: A layer of high-density foam is sprayed onto the back of the shell, providing extra support, preventing heat loss, and suppressing noise, particularly from the pumps. Unlike many hot tubs, British Hot Tubs include insulation both in front of and behind the equipment enclosure for superior noise reduction.
3. Heat Recycling: The insulation system recycles warm air within the cabinet, maintaining water temperature and ensuring maximum energy efficiency.

Additionally, the EcoZone™ Insulation allows easy access for maintenance and servicing, making it a practical and effective solution for the UK climate.
