Marco MT Series Countertop Hot Water Dispensers

Marco MT Boilers: MT4, MT8, MT25

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.

The MT Series offers 9.3” tap-to-tray clearance—great for tall cups and pouring kettles. The MT comes with a removable 3/4" BSP fitting, which can be adapted to the included 1/4" quick-connect (John Guest) fitting. The MT’s familiar spigot design acts just as you’d expect, allowing hands-free pouring when pulled forward or momentary bursts when tapped backward.
