The Xtra Heat Boost pump is an upgrade to the Santai Auto-heat boost pump. Its heat element is activated when the pump is turned on. Operated by the pneumatic Mod power button, it is designed to maintain water heat, ideal for use over lengthy periods of bathing or colder climates.
The element remains on while the pump is active and can only be disengaged when the pump is switched off.
Note: The element is not designed to heat cold water.
