From the quality rocker switches to the higher wattage 52 watt diaphragm ULKA pump, the Isomac Super Giada shows quality inside just as well as the outside. The brass boiler house two thermostats - one for coffee and one for steam - and a safety thermisto for overheat protection. There are 2 hoses in the water reservoir - one for intake and one for the excess pressure that could be biult up by the pump.
