FOGATTI Electric 14kW
Amazon customer rating as of
Tankless Geek editorial score: 4/5
The Fogatti 14 kW electric is the point-of-use member of Fogatti's electric line: 240 volts, roughly 59 amps, and a single 60 A breaker on 6-gauge wire — simpler service than the 18 kW model. It heats water in about three seconds, holds ±1 °F across an 86–140 °F range, and fits a very compact 14.3 × 9.6 × 3.5 in box for under-sink or single-bath duty.
Fogatti lists "up to 3.3 GPM," but 14 kW realistically delivers about 2.7 GPM at a 35 °F rise and well under 2 GPM in cold weather — enough for one fixture, or two in a warm climate. Its natural job is a single point of use, an addition, or a small warm-climate home where the lighter electrical requirement (one breaker, one wire run) makes it easier and cheaper to install than an 18 kW unit.

Our Verdict
A tidy, inexpensive point-of-use electric heater whose lighter single-breaker wiring is its main advantage over the 18 kW model. Right for one fixture or a small warm-climate home; underpowered as a cold-climate whole-house unit. As with the whole line, plan around real temperature-rise flow, not the advertised 3.3 GPM.

How much hot water you'll actually get
Usable flow drops as incoming water gets colder. Figures are calculated from rated output (kW) and labeled as such — not bench-tested by us.
| Temperature rise | Typical scenario | Usable flow |
|---|---|---|
| 35 °F | Warm climate (75 °F in → 110 °F) | 2.7 GPM |
| 45 °F | Mild climate (65 °F in → 110 °F) | 2.1 GPM |
| 60 °F | Cool climate (50 °F in → 110 °F) | 1.6 GPM |
| 70 °F | Cold climate (40 °F in → 110 °F) | 1.4 GPM |
Usable flow at a 110 °F target from 14 kW: kW × 3412 ÷ (ΔF × 500). The 3.3 GPM claim needs a ~29 °F rise (warm inlet); use these numbers to size honestly.
Pros
Cons
Buy it if…
- Single point of use — one bath or kitchen/utility sink
- Small warm-climate homes or additions
- Installs that benefit from one 60 A breaker instead of two
- Budget buyers wanting fast, compact electric hot water
Skip it if…
- Whole-home use in cold climates
- Households running two fixtures in winter
- Buyers needing the advertised 3.3 GPM year-round
Installation Requirements
Professional vs DIY
A single 60 A circuit is DIY-adjacent, but confirm the breaker/wire and permit with an electrician.
3.3 GPM is a warm-inlet figure — cold climates will see less.
Gas and electrical work should be done by a licensed professional, and most installs require a permit and must meet local building codes — DIY work can void the manufacturer warranty. Always confirm the unit's own manual for exact clearances, venting, and sizing.
What owners report
Themes summarized from retailer customer feedback (4.1/5 Amazon customer rating, 245 ratings, as of 2026-09-06). These are owner opinions, not our own bench testing.
Owners like the fast heat-up and small footprint for a single sink or bath, plus the single-breaker wiring versus larger units.
Reviewers cite a low price for capable point-of-use electric hot water.
Satisfaction tracks closely with matching it to one fixture; stretched to a whole house it disappoints, especially in the cold.
Fewer long-term reports than mainstream brands — keep proof of professional installation for the warranty.
FOGATTI Electric 14kW FAQ
How much can the 14 kW heat at once?+
Best for one fixture. It delivers about 2.7 GPM at a 35 °F rise and less in cold weather — two small fixtures only with warm inlet water.
What wiring does it need?+
One 60 A breaker on 6-gauge wire at 240 V — lighter than the 18 kW model's two-breaker setup, which is a big reason to pick it for point-of-use.
How is it different from the Fogatti 18 kW?+
Less power (14 vs 18 kW) and lower flow, but simpler single-breaker wiring. Choose the 14 kW for one fixture, the 18 kW for a small whole home.
What incoming water temperature does the 14 kW need to hit its rated flow?+
A warm one. The 3.3 GPM rating corresponds to only about a 29 °F temperature rise. Estimated from its 14 kW output (roughly 47,800 BTU/h), usable flow drops to about 2.1 GPM at a mild 45 °F rise and around 1.6 GPM at a 60 °F winter rise. That makes the 14 kW a realistic single-fixture or point-of-use heater in most of the country, and only a warm-climate whole-bathroom unit. Size it against your coldest groundwater temperature rather than the advertised flow.
Is the Fogatti 14 kW better suited to point-of-use or whole-home duty?+
For most homes it's a point-of-use or single-bathroom heater rather than a whole-home unit. Its single 60 A / 14 kW circuit produces only about 1.6 to 2.1 GPM once you account for a realistic temperature rise, which comfortably serves one shower or a couple of low-flow sinks but not several fixtures at once. It's a strong fit for additions, cabins, garages, or a dedicated heater for a remote bathroom that a central unit struggles to reach. If you need true simultaneous whole-home hot water, step up to an 18 kW-plus unit and plan for the larger electrical service that requires.
