Key specs explained
Voltage: 240V
You need a dedicated 240V electrical circuit for this unit. Standard 120V outlets will not work, so you must verify your panel capacity. This higher voltage allows the heater to generate enough heat for instant hot water without requiring excessive amperage. If you are unsure about your home’s electrical setup, consult a licensed electrician before installation to ensure safety and proper operation.
Wattage: 14 kW
This power rating determines how quickly the water heats up. At 14 kW, the unit can deliver up to 3.3 GPM when the inlet water is warm. In colder climates, the flow rate may drop to maintain temperature. This wattage is suitable for point-of-use applications or small whole-home setups with limited simultaneous demand, making it efficient for compact living spaces.
Flow Rate: 3.3 GPM
This is the maximum volume of hot water the heater provides per minute. It works best when the inlet temperature is around 77°F. For cooler inlet water, the flow rate decreases to ensure the output reaches your desired temperature. This capacity is ideal for a single shower or a kitchen sink, but may struggle if multiple fixtures run simultaneously.
Temperature Control: 86–140°F, ±1°F
The LED display and knob let you set precise temperatures between 86 and 140°F. The smart chip adjusts rapidly to maintain accuracy within one degree. This precision prevents sudden temperature fluctuations, ensuring consistent comfort. You can dial in the exact warmth you prefer, which is useful for sensitive skin or specific appliance requirements that need stable hot water delivery.
Design and Build Quality
The Fogatti 14 kW unit measures 14.3 by 9.6 by 3.5 inches and weighs 13.3 pounds. According to the listing, this compact footprint allows it to mount directly on a wall. The gray finish and small size make it suitable for tight spaces like small apartments, tiny houses, or cabins. You can install it as a point-of-use heater or in a small whole-home setup where space is limited. The vertical orientation keeps it out of the way while providing easy access to controls.
The front panel features an LED display and a physical knob for temperature settings. You can adjust the output from 86 to 140 degrees Fahrenheit. The listing states that a smart chip adjusts settings 20,000 times per second to maintain a temperature variance of plus or minus 1 degree. This precise control helps you avoid sudden temperature shifts during use. The physical knob allows for manual adjustments without needing to navigate digital menus.
Safety features include overheat and leak protection, with ETL certification confirming compliance with safety standards. The unit requires a dedicated 240V circuit with a 60-amp breaker and 6 AWG wires. You must verify your electrical panel capacity before installation. The compact design and robust electrical requirements mean it is best suited for users with existing infrastructure or those willing to upgrade their electrical setup for instant hot water.
Setup And Everyday Use Guide
Installing this unit requires a dedicated 240V electrical circuit. You must install a 60A breaker and connect one set of 6 AWG wires. The water connection uses a 1/2" NPT fitting. Do not attempt to use 120V power or 15/20A breakers, as the heater will not operate. Verify your electrical panel has sufficient capacity before starting. If you are unsure about your home’s wiring, consult a licensed electrician. This ensures safe and compliant installation.
Daily operation is straightforward. The unit requires a minimum flow of 0.5 GPM to activate. Once water flows, the smart chip adjusts heating 20,000 times per second. This technology maintains the water temperature within ±1°F of your selection. You set the desired temperature using the knob on the LED display. The range spans from 86°F to 140°F. This precise control helps you avoid sudden temperature changes during use.
Performance varies based on inlet water temperature. At 77°F inlet, you get the maximum 3.3 GPM flow. If the inlet is cooler, the flow rate drops to maintain heat. For example, a 42°F inlet supports a shower, while 67°F supports two points simultaneously. For higher temperatures or very cold inlet water, using a single point prevents significant flow reduction. The compact size fits tight spaces, making it ideal for small apartments or point-of-use setups. The ETL certification confirms overheat and leak protection are active during operation.
Before You Buy This Heater
Owning this Fogatti unit means managing electrical upgrades. You must confirm your panel can handle a 60A breaker. Standard 15 or 20A circuits will fail. You also need 6 AWG wires and a dedicated 240V line. Check your local codes for 1/2" NPT fittings. This model suits point-of-use or small apartments. It may not support whole-home use in cold climates. Compare it with other 1 options in our guide. Larger models like the L-27 offer higher flow. Smaller units like the S-11 save space but reduce output. Verify inlet temperatures. Warmer water increases flow. Cooler water reduces it. The smart chip helps maintain steady heat. You do not need an app. The LED display and knob are sufficient. Keep the area clear for ventilation. This electric heater is a practical choice for tight spaces. It fits where gas lines are absent. Ensure your electrician approves the installation before purchasing.
Check before you buy
- Confirm 240V panel capacity for a 60A breaker.
- Check for available 6 AWG wire and 1/2 NPT fittings.
- Verify inlet water temperature affects your expected flow rate.
