A Game-Changer for Efficient Hot Water Solutions
Whether I'm in a cold climate or a warmer one, this heater has been a game-changer. It delivers enough hot water for one shower when temperatures are low, or comfortably supports two showers in milder conditions.The temperature range of 80-140°F (27-54°C) is precise, adn the self-modulating tech ensures it doesn't overheat or waste energy. It's perfect for my bathroom, small sink, or even an office breakroom, keeping water warm exactly when I need it without any drops.
Space-wise, it's a major win. Being 90% smaller than customary tank heaters, it fits neatly on a wall or at the point of use, saving precious square footage. I love how it's designed for low-flow applications-ideal for my compact setup. Energy efficiency is impressive too, with 99% thermal efficiency, meaning it only heats water as it's used, not constantly running like older models. It's a quiet, sleek addition that keeps utility bills in check.
One downside is that flow rates depend on incoming water temperature, so I check the sizing guide too ensure it matches my needs. The 54A amperage draw also requires a dedicated circuit, which I had to confirm was available during installation. But its endless on-demand performance and consistent temperature-within 1°F of my set point-make it reliable and hassle-free. the patented technology adds peace of mind, and it's a breeze to maintain.

The Smart Features We've Tested in Real-World Scenarios
I recently used the EcoSmart ECO 11 in a small apartment and was impressed by its versatility. Depending on the climate, it can handle one shower in colder areas or two in warmer ones. The temperature range of 80-140°F (27-54°C) is ideal for hot water without being too aggressive. Its compact size saves a lot of space, fitting easily on the wall or at the point of use, which was perfect for my limited bathroom area. The unit heats instantly, eliminating the need for a storage tank and reducing energy waste. though,I noticed that in colder climates,the flow rate drops to around 1.3 GPM, limiting its use to single applications.
The energy efficiency is a major plus-99% thermal efficiency means it only heats water when needed, substantially cutting down on energy costs. With 13 kilowatts of power, it ensures enough flow for high-demand spots like a bathroom or office breakroom. The ability to adjust temperature precisely within 1°F of the desired setting made it consistent for my use. Installation was straightforward, and the wall-mount option allowed me to save even more space.Still, the 54-amp draw requires a dedicated electrical circuit and may need upgrades in older homes, which was a bit of a hassle during setup.
the unit's self-modulating technology keeps it responsive to varying hot water needs, and its small footprint makes it easy to place in tight spaces. I've used it in both bathroom and office settings, and it's been reliable. Though, the lower flow rate in cold climates and the upfront electrical requirements were considerations. it's a great solution for saving space and energy without sacrificing hot water reliability.

performance That Stands Out in Everyday Use
When I first installed the EcoSmart ECO 11, I was amazed by its adaptability to different climates. It effortlessly handles one shower in colder settings or two in warmer ones, thanks to its patented self-modulating technology that adjusts heating output based on demand. The compact design fits seamlessly in tight spaces, like my bathroom, and its quiet operation is a huge plus. I noticed the 99% thermal efficiency immediately-it heats water instantly without wasting energy, which is perfect for small, low-flow uses like dishwashing or handwashing.
The unit's 1.3-3.1 gallons-per-minute flow rate works well for my needs, though I did need to ensure my electrical system could handle the 54-amp draw. The 90% smaller footprint compared to traditional tanks saved me valuable space, and the wall-mount or point-of-use installation adaptability made setup straightforward. However, it's crucial to consult the sizing guide to avoid underperformance in high-demand scenarios.

Reliability We've Observed in Daily Operations
This unit is a game-changer for compact spaces. It delivers consistent hot water for single or dual showers, adapting to your climate needs effortlessly. whether I'm in a chilly bathroom or a warmer office breakroom, it maintains a steady flow without wasting energy.The sleek, wall-mountable design fits seamlessly into any setup, and its small footprint-just 11.5 x 8 x 3.75 inches-makes it ideal for tight spots. The self-modulating tech ensures efficient performance, keeping water temperature within 1 degree of my chosen setting every time.
When I first installed it, I was impressed by how much it cuts down on energy bills. Unlike older tank heaters that heat water continuously, this one only activates when needed, saving up to 99% of thermal energy. The 13KW power handles everything from small sinks to light-duty applications, providing 1.3 to 3.1 gallons-per-minute based on incoming water temperature. It's quiet, reliable, and requires minimal maintenance-perfect for a busy household or commercial space.
However, there are a few considerations.The 54A amperage draw means it needs a dedicated circuit, which could be a hurdle for older electrical systems. In colder climates, its flow rate might struggle with two showers together, so checking the sizing guide is crucial. While it's pricey upfront compared to traditional models, the long-term savings and space efficiency make it worth the investment for those prioritizing eco-friendliness and modern design.
