Who it fits
Good fit for
This heater suits homeowners needing hot water at a single sink or shower without waiting. It works well as an in-line booster for existing tank heaters, reducing wait times by providing immediate heat. You should consider it for kitchen sinks, bar sinks, hand-set showers, pool houses, or vacation homes. Its compact size and electric operation make it ideal for backup systems or solar heating setups where space is limited.

You should skip this model if you need to heat water for multiple fixtures simultaneously. The compact 3 by 5 by 12 inch design limits its flow rate to point-of-use scenarios. It is not intended for whole-house heating or high-demand applications like full showers with multiple heads. If you require a larger unit with higher capacity, this electric tankless heater will not meet your needs.
Verdict: The Eemax SPEX90T is a efficient, compact solution for single-fixture hot water needs. Its precise temperature control and small size make it ideal for boosting existing systems or serving remote locations.
Eemax SPEX90T Key Specs Explained
Fuel Type: Electric
This unit runs on electricity rather than gas. You need a dedicated electrical circuit with sufficient amperage to power the heating element. This makes installation easier in locations without gas lines, such as under sinks or in small bathrooms. It also eliminates the need for venting exhaust gases outdoors, allowing for flexible placement in your home.
Dimensions: 3 x 5 x 12 inches
The compact footprint allows this heater to fit into tight spaces like under a sink or in a small closet. You can install it directly at the point of use, which reduces heat loss in pipes. This size is ideal for boosting hot water to a single faucet or shower without taking up valuable cabinet space or requiring a large utility area.
Temperature Control: Microprocessor temperature control
The built-in microprocessor manages the heating elements to maintain a consistent water temperature. This prevents sudden temperature fluctuations when water pressure changes. You get precise heat regulation, which is safer for hand washing and delicate tasks. This feature ensures stable output without manual adjustment, providing reliable performance for daily use in kitchens or bathrooms.
Weight: 4 pounds
At only four pounds, this unit is very light and easy to mount on a wall. You do not need heavy-duty brackets or reinforced studs for support. This low weight simplifies installation for DIYers and reduces the structural load on your home. It is easy to handle during setup and fits well in areas where heavier units would be impractical.

The unit weighs only 4 pounds, making it easy to mount on a wall or secure to a surface without heavy-duty brackets. Its lightweight design simplifies installation for DIYers or plumbers working in confined areas.
The controls rely on microprocessor temperature management. This system provides accurate temperature settings, ensuring consistent hot water output. You do not need to manually adjust dials for every change. The unit accepts both hot or cold water feeds, offering flexibility in plumbing layout. It features 1/2 inch copper pipe compression fittings, which are standard for residential connections. These fittings allow for straightforward hookups to existing plumbing lines.
Electric entry can be routed from the rear or bottom, giving you options for cable management and pipe routing. This adaptability is useful in tight corners or behind walls. The design focuses on practicality and space efficiency. It is built for point-of-use applications like kitchen sinks, bar sinks, or hand showers. The compact size and simple controls make it a practical choice for boosting water temperature in specific locations rather than heating an entire home.
Setup and Everyday Use
Installing the Eemax SPEX90T involves connecting 1/2 inch copper pipe compression fittings. The unit allows for either rear or bottom electrical entry, which provides flexibility during installation. You can connect it to either a hot or cold water feed line. This design supports its role as an in-line booster. It fits easily under kitchen sinks, bar sinks, or in compact utility areas. The compact dimensions of 3 by 5 by 12 inches ensure it does not obstruct surrounding cabinetry.
Daily operation relies on its microprocessor temperature control. This system manages the heating element to deliver accurate water temperatures. The unit produces hot water immediately upon activation. As the hot water from your main tank heater arrives, the SPEX90T gradually reduces its power input. This feature eliminates long waits for hot water while maintaining energy efficiency. It is rated at 99 percent efficient, which minimizes waste during operation.
This setup is ideal for hand-set showers, pool houses, spare bedrooms, or vacation homes. It also serves as a backup system for solar heating setups. The electric fuel type simplifies maintenance compared to gas units, as there are no combustion components to monitor. You simply set the desired temperature and use the water as needed. The white casing blends into most utility spaces. The unit weighs only 4 pounds, making it light to handle during any necessary maintenance or replacement tasks.
Before You Buy This Unit
You need a dedicated electrical circuit with sufficient amperage to power the heating element. This unit runs on electricity rather than gas. Check your breaker panel capacity before installation. The compact size fits under sinks, but verify clearance for maintenance access. You may need additional copper piping and compression fittings if your existing lines do not match the 1/2 inch connections. This heater works well as an in-line booster for existing tank heaters. It also serves as a backup for solar heating systems. Consider its 99 percent efficiency rating when calculating energy use. Unlike whole-house units, this device targets specific points of use. It eliminates long waits for hot water at bar sinks or hand set showers. Ensure your plumbing supports immediate hot water delivery. This model suits vacation homes or spare bedrooms where usage is intermittent. Verify that your electrical setup can handle the load without tripping breakers. Proper installation ensures reliable performance for years.
