Overview: What is the Ecosmart ECO 36?
The Ecosmart ECO 36 is a high-capacity, electric tankless water heater designed to provide an endless supply of hot water for your entire home. Unlike traditional tank-style heaters that store and constantly heat a large volume of water, tankless units only heat water as you need it. This particular model, with its impressive 36kW power rating, is one of the most powerful electric tankless options available, making it suitable for larger homes or those in colder climates where incoming water temperatures are low.
It’s a sleek, compact unit that mounts on a wall, freeing up valuable floor space. The idea is simple: turn on a hot water faucet, and the unit instantly heats the water as it flows through, delivering it to your tap. The ’36’ in its name signifies its 36,000 watts (36kW) of heating power, which is quite substantial for an electric model.
Key Features & What They Mean for You
While the product description might be concise, the implications of its core specifications are huge. Here’s what we know and what it means:
- Powerful 36kW Heating Element: This is the big one! At 36,000 watts, this unit is designed to handle significant hot water demand. It’s meant for whole-home applications, even in areas where the incoming groundwater can be quite cold. This level of power suggests it can comfortably supply hot water to multiple fixtures simultaneously, like two showers and a dishwasher running at the same time, without a noticeable drop in temperature or flow.
- 240V Electric Operation: This means it runs on the same type of power as your electric dryer or oven. It’s important to note that this high power requires substantial electrical infrastructure, which we’ll discuss more in the ‘Cons’ section.
- Tankless Design: No bulky tank means more space in your utility room or garage. More importantly, it means hot water on demand, only when you need it. This eliminates the ‘standby loss’ associated with traditional tanks, where energy is wasted simply keeping water hot.
- Digital Temperature Control: While not explicitly detailed, most modern tankless heaters, especially high-end models like this, feature digital controls. This allows you to set your desired water temperature precisely, typically in 1-degree increments, ensuring comfort and safety.
- Self-Modulating Technology: Again, a common feature for energy-efficient tankless units. This technology adjusts the power input based on the hot water demand. If you’re just washing your hands, it uses less energy than if you’re running a full shower, optimizing energy consumption.
- Compact, Wall-Mounted Design: Its small footprint is a major advantage for homes where space is at a premium. It can be installed in tight spaces, closets, or even outside (with proper weather protection).

Pros & Cons: The Honest Truth
Our community loves honest reviews, so let’s get into what’s great about the Ecosmart ECO 36 and what might give you pause.
Pros:
- Truly Endless Hot Water: This is the number one reason people switch. With 36kW of power, this unit can deliver a continuous stream of hot water, even for larger households with multiple concurrent demands. Say goodbye to rationing hot water!
- Significant Energy Savings (Long Term): Because it only heats water when needed, there’s no energy wasted keeping a tank full of water hot 24/7. This ‘on-demand’ heating can lead to noticeable reductions in your electricity bill over time compared to a traditional tank heater, especially if your current tank is older or inefficient.
- Space-Saving Design: Its compact size and wall-mount capability free up valuable floor space in your utility room, basement, or garage. This is a huge plus for smaller homes or those looking to maximize storage.
- Precise Temperature Control: The ability to set your exact desired temperature digitally offers comfort and can help prevent scalding. You’re not stuck with a factory-set temperature; you can customize it to your preference.
- Longer Lifespan: Tankless water heaters generally have a longer lifespan (15-20 years) compared to traditional tank heaters (10-12 years), as they are less prone to corrosion.
- Reduced Risk of Leaks: Without a large tank storing gallons of water, the risk of a catastrophic leak and subsequent water damage is significantly reduced.
- Good User Rating: With a 4.1-star average from over 700 reviews, it’s clear that many users are very satisfied with this product’s performance.
Cons:
- Very High Electrical Requirements: This is the biggest hurdle for many. A 36kW unit operating at 240V requires a massive amount of amperage, typically needing *three* dedicated 40-amp double-pole breakers and corresponding heavy-gauge wiring (e.g., 8-gauge). Many older homes, or even some newer ones, may not have the spare capacity in their electrical panel or the necessary wiring, leading to significant upgrade costs for installation. You absolutely need to consult a qualified electrician before purchasing.
- Higher Upfront Cost: The unit itself is more expensive than most traditional tank water heaters. When you factor in potential electrical upgrades and professional installation, the initial investment can be substantial.
- Complex Installation: While the unit is compact, installing a high-power electric tankless heater is not a DIY job for most homeowners. It requires a licensed electrician for the wiring and often a plumber for the water lines, adding to the overall cost.
- Potential for Flow Rate Limitations (in very cold climates): While 36kW is powerful, in regions with extremely cold incoming water (e.g., below 40°F / 4°C), running multiple high-demand fixtures (like two showers and a washing machine) simultaneously might still result in a slight decrease in water temperature or flow. The unit has to work harder to raise the water temperature significantly.
- Requires Minimum Water Flow for Activation: Tankless heaters only turn on when a certain minimum flow rate is detected. If you have very low water pressure or are only opening a faucet slightly, the unit might not activate, meaning no hot water.
- Maintenance for Hard Water Areas: Like all water heaters, tankless units require periodic descaling, especially in areas with hard water, to prevent mineral buildup and maintain efficiency. This adds to maintenance effort.
- Energy Consumption Can Be High If Overused: While it saves energy by not having standby loss, if you run hot water for excessively long periods or have very high demand, the instantaneous power draw (36kW!) can be substantial, and your electricity bill could still be high.
