Who it fits
Good fit for
You should consider this unit if you need hot water for a single sink or small bathroom. The 19 kW output is sufficient for low-flow fixtures. Its compact size fits well in closets or under counters where space is limited. The 240V requirement means you need the correct electrical circuit installed. If you are upgrading an older home with adequate wiring, this electric model offers high efficiency and reliable performance for personal use.
Who should skip it
Skip this model if you need to supply hot water for multiple fixtures simultaneously. The 19 kW capacity is too low for showers or tubs in many climates. You also cannot use this unit if your home only has 120V outlets available. It requires a dedicated 240V circuit. If you live in a cold climate and need high flow rates, this unit will struggle to maintain temperature. Look for a higher wattage model for whole-house applications.
Verdict: The Eemax EX190T2 is a highly efficient, compact solution for low-demand electric applications. It suits users who need reliable point-of-use heating in tight spaces.
Key specs explained
Wattage: 19KW
This power rating determines how quickly the unit heats water. A 19 kW output supports point-of-use applications like a single sink or shower. It delivers consistent hot water without the delay of a tank. You should verify that your home’s electrical panel can handle this load. Higher wattage generally means faster recovery rates for continuous use.
Voltage: 240V
This unit requires a dedicated 240-volt circuit, similar to a standard dryer outlet. It does not run on standard 120V household power. You must have the correct wiring and breaker installed. This voltage level is necessary to drive the 19 kW heating elements efficiently. Check your electrical setup before installation to ensure safety and proper operation.
Dimensions: 5 x 11 x 11 inches
The compact footprint allows this heater to fit in tight spaces. It is small enough to mount under sinks or in closets. The 5-inch depth is particularly useful for narrow cabinets. This size makes it ideal for retrofitting into existing spaces where a traditional tank would not fit. Measure your available area carefully to ensure a proper fit.
Temperature Control: Thermostatic control
This feature allows you to set a precise outlet temperature. It maintains consistent water heat without manual adjustments. You can prevent scalding by setting a specific limit. This level of control is essential for comfort and safety. Compare this to basic on/off units that lack fine-tuning options for steady performance.
Design and build overview
According to the listing, the Eemax EX190T2 measures 5 by 11 by 11 inches. This compact footprint allows it to fit into tight spaces where a traditional tank would not. The gray finish is listed as a standard exterior option. You can mount this unit on a wall to keep floor space clear. The small size makes it suitable for point-of-use installations, such as under a sink or near a shower.
The water connections are located on the bottom of the unit. They use a 3/4 inch NPT standard. This layout simplifies plumbing work because you can run pipes directly upward or downward without complex elbow joints. Bottom connections often reduce the need for additional fittings, which can lower installation time and potential leak points.
Temperature control is handled by a thermostatic mechanism. This feature maintains a precise outlet temperature rather than fluctuating with water pressure changes. You get consistent heat output, which is critical for comfort in point-of-use scenarios. The unit is electric and requires a 240V power supply. This voltage requirement means you must ensure your electrical panel can support the load before installation. The design prioritizes efficiency and space savings over large capacity.
Setup and everyday use guide
Installation begins with connecting the water lines to the bottom of the unit. The listing specifies 3/4 inch NPT water connections located on the bottom. This bottom-mount design simplifies plumbing runs in tight spaces. You will need to ensure your electrical panel provides a dedicated 240V circuit. The 19 kW power draw requires appropriate wiring and breaker capacity. Once wired, the unit relies on its thermostatic control system. This feature allows you to set a precise outlet temperature. You do not need to adjust settings frequently. The thermostat maintains the water heat as flow rates change. Daily use is straightforward. You turn on the faucet, and the unit heats the water instantly. There is no waiting for a tank to recover. The compact size means it does not dominate your utility area. The gray exterior blends into most mechanical rooms. Energy efficiency is listed at 99%. This high rating suggests minimal standby heat loss. You pay only for the energy used to heat the water flowing through the unit. The design supports point-of-use applications effectively. It is ideal for single sinks or showers where long pipe runs would waste water and heat. The compact dimensions allow it to fit where larger units cannot. You simply enjoy consistent hot water without the bulk of a traditional storage tank.
Before you buy this unit
You need to confirm your electrical panel can handle the load. This 19 kW model requires a dedicated 240V circuit. Check your amperage capacity before purchasing. You will likely need heavy-gauge wiring and a specific breaker. The unit is designed for point-of-use tasks. It suits a single sink or shower. It does not serve whole homes. Compare it to higher-kW models if you need more flow. The compact size fits tight spaces. This makes it ideal for closets or under sinks. Maintenance is minimal. You should flush the unit annually to remove mineral buildup. This keeps the heating elements efficient. The 99% energy efficiency rating is a key benefit. It reduces waste compared to tank heaters. Ensure your water pressure is adequate. Low pressure can affect performance. This unit is not a replacement for a central heater. It is an add-on for specific fixtures. Verify your plumbing connections match the 3/4 inch NPT ports. Proper installation ensures safety and longevity.
Check before you buy
- Verify your electrical panel has space for a 240V dedicated circuit
- Confirm your wiring gauge meets the 19 kW power requirement
- Check that your plumbing uses 3/4 inch NPT bottom connections
- Ensure the installation space fits the 5 by 11 by 11 inch dimensions
- Decide if point-of-use heating meets your single fixture needs
