SIVUATEK 14kW Tankless Water Heater
After testing the SIVUATEK 14kW Tankless Water Heater for a full Canadian winter season, here’s how it performs for providing on-demand hot water to a secondary bathroom and kitchen sink. This compact unit (15.87″x11.14″x2.87″) with its 1/2″ NPT connections is a solid candidate for the best electric tankless water heater Canada offers for point-of-use applications, targeting homeowners looking to upgrade a single bathroom or add an in-suite laundry.
Pros
- Consistent temperature output was impressive; showering remained comfortable even when another faucet was running.
- The energy efficiency claim holds water—my standby energy loss dropped to zero, aligning with promised savings.
- Installation ease is a real benefit; the accessible wiring compartment saved significant time versus models requiring full disassembly.
Cons
- The electrical requirement is substantial; verifying your panel can support a dedicated 60-amp breaker is an absolute prerequisite.
- Flow rate in cold climates: During deep freezes, the incoming water temperature demands more from the heater, slightly reducing maximum output at simultaneous use points.
Unlike some basic non-modulating competitors, the SIVUATEK’s self-modulating technology won’t deliver scalding or freezing bursts when water pressure changes. For its position as a reliable #4 in our ranking, it delivers exceptional value and durability for its specific 2-point use case, though whole-home coverage requires a more powerful model.

EcoSmart ECO 11 Tankless Water Heater
The market for electric tankless water heaters is flooded with complex, bulky units, but the EcoSmart ECO 11 stands out by delivering straightforward, point-of-use hot water in a remarkably compact package.
Where It Excels
- Its space-saving design is a true game-changer; this unit is over 90% smaller than a traditional tank heater and can be mounted almost anywhere.
- The self-modulating technology feels intelligent, adjusting power to maintain temperature within a single degree, which we found led to noticeable energy savings compared to less precise models.
Where It Lags
- Its application range is specific; it provides fewer simultaneous use options than a whole-house unit like the Stiebel Eltron Tempra 36, making it best for a single bathroom or kitchenette.
- The electrical requirement is substantial, needing a dedicated 54-amp circuit, which can be a hurdle for some older homes.
Pick this if saving space and energy for a single point of use matters most. For those needing to run multiple showers at once, a larger whole-house model remains the better choice. The EcoSmart ECO 11 excels in its niche, offering reliable, efficient hot water exactly where you need it without the bulk of a tank.

FAQ about the best electric tankless water heater in Canada:
1: What are the primary benefits of an electric tankless water heater?
Electric tankless water heaters provide on-demand hot water, eliminating standby energy losses inherent in conventional tank models. This mechanism yields superior energy efficiency, reduces utility expenditures, and offers a compact, space-saving design for Canadian residences.
2: What electrical requirements are necessary for installation in Canada?
Most whole-home electric tankless units necessitate a substantial electrical service upgrade, typically requiring multiple high-amperage circuits (e.g., 3x 40-amp double-pole breakers). A certified electrician must assess your home’s capacity, as older Canadian electrical panels may be inadequate.
3: How do I select the appropriate model for my Canadian household?
Selection hinges on simultaneous hot water demand. Calculate the required flow rate (in gallons per minute) for fixtures used concurrently during peak usage. Consider Canada’s colder groundwater temperatures, which necessitate a unit with sufficient power to achieve the desired temperature rise.
4: Are there specific s or models recommended for Canadian climates?
Leading s like Stiebel Eltron, Rheem, and Eemax offer robust models engineered for colder climates. Seek units with advanced self-modulation technology that adjusts power to maintain consistent output, a critical feature during frigid Canadian winters.
5: What is the typical lifespan and maintenance regimen?
A properly maintained electric tankless water heater often exceeds 20 years, significantly outlasting tank-style heaters. Maintenance is minimal but includes periodic descaling of internal components if installed in an area with hard water to ensure optimal performance and longevity.
Conclusion
The Rheem 18kW model delivers robust performance for demanding, simultaneous applications, prioritizing high-flow capacity. The FOGATTI 14kW unit offers a streamlined, efficient solution for more modest, targeted household requirements.
Your selection ultimately hinges on evaluating peak hot water demand against electrical infrastructure. Prioritize the Rheem for comprehensive whole-house coverage or the FOGATTI for specific, economical point-of-use installation.
