Marco Mix UC3 Under-Counter Hot Water Boiler (Used)
This used Marco Mix UC3 under-counter water boiler delivers precise, on-demand hot water at three programmable temperatures and three volumes — ideal for cafés that need flexible water dispensing for tea, pour-over, Americanos, or other hot beverages without taking up valuable counter space. The vacuum-insulated tank keeps water at a consistent, reliable temperature while improving energy efficiency, and the under-counter design keeps only a sleek dispensing font visible to customers.
This particular unit was previously installed in a low-traffic café that has since closed. Before resale, it went through a thorough inspection and maintenance process, including upgraded safety components and replacement fill probes and fill valve — so it's tested, verified, and ready for installation rather than sold as-is.

Warranty coverage may vary by manufacturer, but the following outlines the standard warranty policies for equipment purchased through our company.
Used & Refurbished Equipment Warranty
Used or refurbished machines sold by us include:
- 3-month parts warranty
- 3-month labor warranty (within our service area)
These warranties cover defects in parts and workmanship, but do not cover normal wear components.
Warranty details may vary depending on the specific used or refurbished machine. Please consult your salesperson for complete information or with any questions regarding warranty coverage.
Customers Outside Our Service Area
Customers located outside our service area can still purchase equipment from us.
In these cases, we will:
- Help connect you with a trusted local service partner
- Coordinate installation support
- Assist with manufacturer warranty claims
- Provide guidance for long-term service and maintenance
Some manufacturers also offer authorized installation packages, which we can help coordinate.
Installation Requirements
Customers are responsible for ensuring that their site is properly prepared prior to installation.
This includes, but is not limited to:
- Electrical requirements
- Plumbing connections
- Proper drainage
- Adequate counter space and ventilation
- Required water filtration systems
If the site is not ready when the technician arrives, additional service and travel charges may apply, and installation may need to be rescheduled.
Water Quality & Filtration Requirements
Proper water quality is one of the most critical factors in protecting coffee equipment.
Water that is too hard, too soft, or improperly filtered can cause:
- Scale buildup
- Boiler damage
- Valve and pump failure
- Premature equipment breakdown
Damage related to poor water quality, scale, or lack of filtration is not covered under warranty.
Many manufacturers provide water testing guidelines or kits. For example, some espresso machine manufacturers include water test kits to verify that water meets their specifications.
Espresso Analyst can help with:
- Installation of appropriate water filtration
- Test water quality where required
- Maintain and replace filters according to manufacturer guidelines
Failure to meet manufacturer water specifications is one of the most common causes of equipment failure and warranty denial.
Our team is happy to recommend appropriate filtration solutions during the purchasing process.
