How Much is a Hot Tub: Factors
1. Energy Efficiency of the Hot Tub
Modern, well-insulated hot tubs use far less energy than older or budget models. Look for features like:
- Full foam insulation
- Energy-efficient pumps
- Insulated covers
2. Usage Frequency
The more you use your hot tub, the more energy it uses to maintain temperature and filter water. Daily use will cost more than occasional weekends.
3. Ambient Temperature
During winter months, it costs more to keep water at a constant 37–40°C. If your hot tub is outside, windbreaks and covers can help conserve heat.
4. Heater & Pump Size
Larger tubs with bigger heaters and more jets consume more electricity, especially during heating cycles.
5. Water Chemistry Balance
Poor water maintenance can cause your system to work harder, especially if filters clog or bacteria build-up occurs.
Pro Tip: Use a floating thermal blanket to trap heat and reduce heat loss, particularly in colder regions of the UK.
How to Reduce Your Monthly Running Costs
- Choose the Right Hot Tub: Look for energy-rated or “eco” models with thick insulation.
- Maintain Your Water: Regularly balance pH and sanitise to reduce the strain on pumps and heaters.
- Use a High-Quality Cover: Keep heat in and debris out with a well-fitting, insulated lid.
- Limit Jet Usage: Jets require extra energy — use them in moderation for energy savings.
- Heat Smartly: Lower the temperature when not in use for long periods, and invest in a programmable timer or Wi-Fi control system.
