How it plans

Planning beats switching off.

A price limit stops the heating when power is expensive and heats in every other hour. SpaControl works out how much heat your spa needs tomorrow and uses the cheapest hours to deliver it.

The amount of heat is the same. It is bought at a better price, and the spa reaches your temperature on time.
