@primacoffee: Marco’s MT Series boilers provide impressively consistent and stable hot water in three capacities: 1 gallon (MT4), 2.1 gallons (MT8), and 6.6 gallons (MT25). Featuring a “Step-Fill” system, these boilers refill with ambient water in controlled 3-second bursts, pausing for 9 seconds to maintain superb temperature stability within just a few degrees, liter after liter. For output, the 110V models produce up to 3.5 gallons per hour, while 220V models deliver 7+ gallons per hour. Need even more? Switch to “Continuous Fill” mode for instant full refills, prioritizing volume over temperature stability. Watch the full video at the link in bio.
