Choosing the best water heater from remplacement chauffe eau montreal for a small home or apartment comes down to balancing space efficiency, energy consumption, capacity, and installation requirements. In compact living spaces, bulky systems can be impractical, so modern homeowners increasingly favor smaller tank units or tankless (on-demand) systems. Tankless models, in particular, are popular because they heat water only when needed, saving both space and energy while providing continuous hot water.
Below is a curated guide to some of the best water heaters for small homes and apartments, along with key insights to help you decide.
Best overall: Compact tankless electric solution
The EcoSmart ECO 11 Electric Tankless Water Heater stands out because it combines small size, affordability, and reliable performance. It’s ideal for apartments with one bathroom or limited simultaneous water usage. Tankless units like this eliminate standby heat loss, making them more efficient than traditional tanks.
Best budget option: Entry-level tankless
The ThermoMate Electric Tankless Water Heater is a great value pick. It’s compact enough to install under sinks or in closets and works well for point-of-use applications. While it may not support multiple fixtures at once, it’s perfect for studios or single occupants.
Best for whole-apartment use: High-capacity electric tankless
The Stiebel Eltron Tempra 24 Plus Tankless Water Heater is designed for larger apartments or small homes. It offers higher flow rates and advanced temperature stabilization, ensuring consistent hot water even when multiple taps are in use.
Best compact tank option: Space-saving traditional heater
The GSW Space Saver Electric Water Heater SS650SDE-30 is ideal for those who prefer a traditional system. It’s easier to install than tankless systems and provides instant hot water without the need for high electrical capacity.
Best mini point-of-use heater
The Stiebel Eltron Mini 3.5 Point-of-Use Tankless Water Heater is an ultra-compact unit designed for under-sink installation or boosting hot water in specific areas. It’s not meant for whole-home use but excels in micro-apartments or offices.

Key considerations when choosing
1. Size and space
Tankless heaters are wall-mounted and significantly smaller than traditional tanks, making them ideal for tight apartments. If space is extremely limited, a point-of-use model may be your best option.
2. Hot water demand
Consider how many fixtures will run simultaneously. A single-person apartment may only need a low-flow tankless unit, while a family in a small home might require a higher-capacity system.
3. Energy efficiency
Tankless systems are generally more efficient because they avoid standby heat loss. However, they may require electrical upgrades, especially in older buildings.
4. Installation complexity
Tank heaters are easier and cheaper to install. Tankless systems often require professional installation and electrical or gas line upgrades.
5. Budget
Upfront costs for tankless heaters are higher, but they often last longer and reduce energy bills over time. Traditional tanks are cheaper initially but less efficient.
For most small homes and apartments, a tankless electric water heater is the best choice due to its compact design and energy efficiency. However, if installation constraints or budget are concerns, a space-saving tank model remains a practical alternative. Ultimately, the right choice depends on your household size, usage patterns, and available installation space.
