The T500 Boiler is the recommended boiler base for use with the T500 Reflux Condensers and Alembic Dome & Condenser. Made from 304 grade stainless steel, this boiler features dual element control switches, a stainless steel ball valve tap and an automatic reset switch. The dual element control switches provide more control during distillation - when both switches are in the ON position, the element will be supplied full power of 2200W (1600 if using a US/CA unit). When one switch is in the OFF position, it will only consume 1100W (or 1100W/500W if using a US/CA unit) of power. Adjusting the power can be useful in areas with warmer tap water for cooling and for use with the Alembic Pot Still.
