Frequently Asked Questions

Does this heat the bath from cold? No, it is designed to maintain temperature while the whirlpool is running, not to heat a cold bath.

Can it share the same electrical supply as the pump? Yes, it can share the standard 13-amp fused spur, or you can use a separate 13-amp supply if preferred.

Can I turn the heater off independently? No, it activates automatically with the whirlpool pump. A separate supply allows you to isolate it easily if needed.

Is the heater safe? Yes, it uses a safe composite casing, unlike some cheaper metal versions.
