Are Whirlpool Baths Energy Efficient?
Yes, whirlpool baths can be energy efficient when used responsibly. Here’s what to know about their energy usage:
Basic Operation Costs
- Jet Pump Power: Most jet pumps use 750W to 1kW, similar to a household appliance.
- Average Cost: A 20-minute session typically costs 15–20p in electricity.
- Water Heating: The primary energy cost comes from heating the water, which is the same as for a standard bath. Whirlpool baths rely on your home’s hot water supply and do not include built-in heaters as standard.
Optional Heater Systems
If you opt for an inline heater:
- Power Usage: Heaters typically consume 1.5–2kW, slightly increasing running costs.
- Purpose: They maintain water temperature during extended sessions, offering comfort for longer soaks.
- Energy Impact: Use heaters selectively to minimize energy use.
Tips to Reduce Energy Use
- Fill Efficiently: Only fill the bath to the level needed for jets to operate.
- Use Immediately: Bathe shortly after filling while the water is still hot.
- Maintain Equipment: Regular maintenance ensures the pump runs efficiently.
- Insulate: Use a bath cover or insulated panels to retain heat between uses.
- Optimize Timing: Align bath times with your boiler’s most efficient heating periods.
Cost-Saving Features
- Modern Efficiency: Today’s pumps are more energy-efficient than older models.
- Smart Controls: Some systems include automatic cut-offs when water levels drop (with electronic controls).
- Insulation: Newer models often have insulated panels to maintain water temperature.
When used sensibly, whirlpool baths are economical to operate, with water heating being the largest energy expense—just like a regular bath.
