Heat Pumps

Hot Tub Heat Pumps

Heat pumps are the smartest way to reduce hot tub running costs in the UK. Instead of generating heat like a standard electric heater, a heat pump moves heat from the air into your water — which can deliver more heat per unit of electricity used, especially in mild-to-cool conditions.

Choose your heat pump in 60 seconds

  • Inverter models: most popular. They adjust output to demand for quieter operation and better efficiency.
  • Higher output: faster heat-up and better performance in colder weather (ideal for year-round users).
  • Swim spas / larger volumes: choose a unit designed for higher water volume and heavier usage.

What to check before you buy

  • Your water volume: larger tubs need higher output for fast heat-up.
  • How you use the tub: weekends only vs most nights changes what “best value” looks like.
  • UK temperatures: colder evenings need stronger capacity to maintain temperature efficiently.
  • Placement: heat pumps need airflow clearance and sensible positioning.

If you're unsure, message us your hot tub model (or water volume in litres), and we’ll recommend the best size and type.
