Who it fits
Good fit for
This unit suits commercial settings with dedicated three-phase power. You should choose this if you need a high-output electric heater that fits in a small footprint. It works well in restaurants or salons where consistent hot water is critical. The compact size helps save space in utility rooms. Ensure your electrical panel supports 480/277V before installing.
Who should skip it
Skip this model if you are in a residential home. Most homes use single-phase 120V or 240V power. This heater requires 480/277V, which is rare in houses. You will also need a professional electrician for installation. If you lack three-phase infrastructure, this unit will not work. Look for a standard residential tankless heater instead.
Verdict: This is a specialized commercial heater for buildings with three-phase power. It offers efficient hot water delivery in a small package. Verify your electrical specs before buying.
Key Specs for Eemax 18kW
Wattage: 18KW
This unit outputs 18 kilowatts of heating power. Higher wattage generally means faster recovery rates for hot water. You need this level of output for commercial settings with moderate simultaneous demand. Compare it to lower wattage residential models which heat water more slowly. This spec ensures you get steady flow during busy periods without waiting for a tank to refill.
Voltage: 480/277V
This heater requires a three-phase commercial electrical circuit. It will not work with standard home outlets. You must have a qualified electrician install the proper wiring. This voltage supports the high 18 kW power draw safely. Check your building’s electrical panel before purchase. Residential units typically use 240V, so this is a distinct commercial requirement.
Fuel Type: Electric
The unit uses electricity rather than gas or propane. This eliminates the need for gas lines or venting. You avoid combustion risks and exhaust flues. Electric models often have lower upfront installation costs if wiring is already in place. However, check your local electricity rates. Gas may be cheaper to run in some areas, but electric offers simpler maintenance.
Dimensions: 4.25"L x 12.25"W x 15.25"H
The compact footprint allows mounting in tight utility spaces. You can fit it in closets or mechanical rooms where space is limited. Compare this size to bulky tank-style heaters that take up floor space. Ensure you have enough clearance for airflow and service access. The small size also makes it easier to route plumbing connections in confined areas.
Design and Build Quality
The Eemax ED020480T2T is built for tight commercial spaces. According to the listing, its physical dimensions are 4.25 inches in length, 12.25 inches in width, and 15.25 inches in height. Another spec sheet lists the width as 13 inches, height as 5 inches, and length as 15 inches. These slight variations in reported measurements suggest you should verify the exact footprint with the manufacturer before installation. The unit weighs 13.3 pounds. This light weight makes it easy to mount on a wall without heavy-duty brackets. It does not require a reinforced floor or a large concrete pad.
The finish is listed as "No Finish." This means the exterior is likely bare metal or has a minimal industrial coating. You should plan for a dry indoor environment. Moisture or outdoor exposure could damage the casing over time. The compact layout allows you to install it near the point of use. This reduces heat loss in the pipes. You can place it in a utility closet or under a sink in a commercial kitchen.
Controls are not detailed in the provided data. You will need to check the manual for interface details. The lack of listed smart features means you will manage temperature manually. This is standard for basic commercial electric units. The design prioritizes function over form. It is a straightforward, no-frills appliance meant for reliable hot water delivery in business settings.

Frequently asked questions
Can I install this Eemax heater in my home?
No. This unit requires a 480/277V three-phase power supply. Standard residential homes typically use single-phase 120V or 240V circuits. You would need significant electrical upgrades to support this voltage. It is designed specifically for commercial facilities with the correct industrial power infrastructure. Do not attempt installation in a standard house.
How much hot water does it provide?
It delivers on-demand hot water at a rate determined by its 18 kW heating power. The unit heats water instantly as it flows through the electric elements. It does not store water in a tank. The flow rate depends on the incoming water temperature and your desired output temperature. Higher wattage allows for faster recovery.
What are the exact dimensions of the unit?
The listing provides slightly varying measurements. One source lists the size as 4.25 inches in length, 12.25 inches in width, and 15.25 inches in height.
