Amerec AK generators are purpose-designed for home use, transforming your shower or bathing room into a daily invitation to comfort.

The AK generator uses full power to quickly heat up the steam room to it's pre-set temperature, then cuts the power by 1/3 or 2/3 of its heating elements. The result is a more consistent flow of steam and more stable temperature.

Available in 4 popular sizes - 4.5kW, 7.5kW, 11kW and 14kW.  

Built without compromise, should attention ever be required engineers and genuine parts are always available to keep your steam room in service.
