Who it fits
Good fit for
This heater suits homes or businesses with existing 277V electrical infrastructure. It is ideal for point-of-use applications where space is limited, such as under sinks or in closets. The compact design and low weight make it easy to install in tight areas. You will appreciate the precise thermostatic control if you need consistent water temperatures. The 99% efficiency is beneficial for reducing energy waste in dedicated hot water lines.
Who should skip it
Skip this model if your home only has standard 120V or 240V circuits. The 277V requirement means you need specific electrical wiring, which may not be present in most residential settings. It is not suitable for whole-house heating due to its limited 16 kW capacity. If you need a unit with remote controls or smart connectivity, this model does not offer those features. Look elsewhere if you require larger water flow rates for multiple fixtures simultaneously.
Verdict: The Eemax EX160TC is a specialized, efficient solution for 277V circuits and tight spaces. It delivers precise temperature control in a small, lightweight package.
Key specs explained
Voltage: 277V
This unit requires a 277-volt electrical supply, which is common in commercial or specific residential three-phase systems. You must verify your home or building has this specific voltage before purchase. Standard 120V or 240V circuits will not work. Using the wrong voltage can damage the heater or prevent it from starting. Check your electrical panel or consult an electrician to confirm compatibility with your existing infrastructure.
Wattage: 16Kw
The 16-kilowatt rating determines how much water you can heat at a given flow rate. This capacity suits point-of-use applications like a single sink or shower in a compact space. Higher wattage generally means more hot water output, but it also demands more electrical power. Compare this to lower 8kW or 10kW units for smaller needs, or higher 20kW+ models for whole-house demands in warmer climates.
Dimensions: 5 x 11 x 11 inches
These compact measurements allow the heater to fit in tight spaces such as under sinks, in closets, or utility rooms. The small footprint is ideal for retrofitting into existing cabinets without major remodeling. Measure your available space carefully to ensure the unit fits. This size is significantly smaller than traditional tank-style heaters, freeing up valuable floor or wall space for other storage or equipment needs.
Temperature Control: Thermostatic control
Thermostatic control allows you to set a precise outlet water temperature. This feature ensures consistent warmth without sudden hot or cold spikes. You can adjust the setting to suit your comfort level or specific appliance requirements. This level of precision is helpful for protecting sensitive fixtures or ensuring safe water temperatures for children and elderly users in the household.
Design and Build Details
According to the listing, this unit measures 5 by 11 by 11 inches. The compact footprint allows you to mount it in tight spaces where larger traditional tanks would not fit. The gray finish is standard for utility equipment. This color choice helps the device blend into mechanical rooms or utility closets without drawing attention.
The unit weighs 8 pounds. This light weight makes it easy for one person to handle during installation. You can mount it on a wall without needing heavy-duty support brackets. The bottom water connections use 3/4 inch NPT fittings. This layout simplifies plumbing work by keeping pipes away from the wall, reducing the need for complex elbow joints.
Thermostatic control is built into the design. This system maintains precise outlet temperatures without constant manual adjustment. You get consistent hot water flow. The electric fuel type means no gas lines are needed. This design suits locations where gas service is unavailable. The compact size and specific voltage requirements make it ideal for point-of-use applications or small commercial setups. Always verify your electrical capacity matches the 277V requirement before installation.
Setup And Everyday Use Guide
Installation requires careful attention to electrical and plumbing specifications. This unit operates on 277 volts, so you must confirm your building has the correct power supply. Standard residential circuits will not support this heater. You will need appropriate wiring and a dedicated circuit breaker to handle the 16 kW load safely.
Plumbing connections are located at the bottom of the unit. The listing specifies 3/4 inch NPT water connections. This bottom-mount design simplifies routing pipes in tight spaces or utility closets. The compact dimensions of 5 by 11 by 11 inches allow you to mount the device where space is limited. Its small size means it fits easily into areas where a traditional tank would not.
Daily use is straightforward. The thermostatic control lets you set a precise outlet temperature. This feature ensures consistent hot water delivery without manual adjustments for each use. The unit is 99% energy efficient, meaning it heats water only when you turn on the tap. There is no standby heat loss. You get hot water on demand, which reduces energy waste. The gray finish is durable and blends with standard utility equipment. Maintenance is minimal, as there are no tanks to flush or replace. You simply enjoy reliable, endless hot water for your sink or shower, provided your electrical system meets the 277V requirement.
Before You Buy This Unit
You need to verify your electrical system supports 277 volts. This heater will not work on standard 120 or 240 volt circuits. You must confirm your building has the correct power supply before ordering. The unit uses 3/4 inch NPT connections on the bottom. Ensure your plumbing lines align with these bottom-mounted ports to simplify installation. You may need specific adapters or additional piping to connect properly. The compact design saves space, but you still need room for maintenance access. This model is 99% energy efficient, which helps lower your utility bills over time. It fits well in tight utility closets or under counters where traditional tanks fail. Compare this electric option with gas models if you lack the necessary high-voltage wiring. Check your local codes for commercial versus residential restrictions. Proper sizing is critical for your hot water needs. This unit suits specific setups rather than general home use.
Check before you buy
- Confirm your building has a 277-volt electrical supply.
- Check that your plumbing uses 3/4 inch NPT connections.
- Verify local codes allow electric tankless heaters in your space.
- Ensure you have enough clearance for maintenance access.
