Frequently Asked Questions

Which kW size do I need for my spa?

As a general guide: the 2.3kW suits small portable spas (up to ~800L), the 4.5kW suits medium spas (~800–1,500L), and the 6.0kW suits larger spas or situations where faster heat-up time is required. Actual heating time depends on spa volume, ambient temperature, and insulation. Contact us if you need help selecting the right size.

Does this heater include a pump and filter?

No — the Davey Spa Power Classic is a standalone heater only. It must be installed in conjunction with a compatible pressure pump and filter system. It is not a complete spa pack.

Can it be installed horizontally?

Yes — the Davey Spa Power Classic can be installed in either a vertical or horizontal configuration, providing flexibility for tight or unusual installation spaces.

How is the heater controlled?

The heater is activated by an externally mounted air switch control system and features a single dial for temperature adjustment. The air switch is typically mounted on the spa cabinet or surround for easy access.
