HOW DOES AN AIR SOURCE HEAT PUMP WORK?
The fan in the air source heat pump draws air over a network of tubes that look a little like a car radiator. These tubes are filled with an eco-friendly R32 refrigerant. The air then passes over the tubes warming up the refrige
st-effective solution to heat your hot tub or swim spa, but it is also a much more eco-friendly option.

HSG282 Compliance Information

HSG282 is the UK Health & Safety Executive’s guidance for controlling the risk of Legionella and other infectious agents in hot tubs used in holiday lets and similar business settings. If you provide a spa for paying guests, compliance with this standard is strongly recommended.

Our Holiday Let range has been designed with HSG282 in mind, helping operators meet the key requirements:

  • Automatic chemical dosing (chlorine/bromine) – no floating dispensers.
  • Ozone/UV secondary sanitisation for added protection.
  • Hydraulic design for rapid water turnover (approx. 15 minutes).
  • No air blowers, reducing aerosol risk.
  • Continuous filtration and heating via automated cycles.
  • Easy water testing with clear access points for twice-daily checks.
  • Risk assessment templates and logbooks provided to support record keeping.
Important to Note

Actual compliance depends not only on spa design, but also on how the spa is operated and maintained:

  • Carrying out twice-daily water tests (disinfectant & pH).
  • Weekly (or per changeover) water changes.
  • Keeping accurate maintenance and testing records.
  • Following safe bather load limits and displaying user rules.

Our HSG282-ready spas make it easier to stay compliant, safe, and audit-prepared in holiday let environments.
