A fantastic entry-level water heater that's best used for small homes, condos and apartments.

The EcoSmart 8 water heating is a tankless water feature that works on 240 volts to operate. Compact, sleek, and affordable, this water heater is designed for home use. It’s so compact that it could save up to 12 cubic feet of storage space in the home. Even better, the brand promises to help you save up to 60% of water heating cost thanks to the EcoSmart 8’s self-modulating technology!

Perfect for households that require a steady supply of hot water, the EcoSmart 8 delivers incoming water temps of about 67°F and above. It comes with a digital temperature control, offering more control over how hot you’d like your water to be. Ideal for warm and cold climates alike, this water heater is not only efficient, it’s also durable. So durable in fact that the EcoSmart is throwing a lifetime warranty for residential use.

This water heater requires a minimum of 100 amp electrical panel for installation. The Eco8 comes complete with ½ inches plumbing connections, compression fittings, and NPT adapter. Using this water heater, we found that it is easy to install and there were no leaks to speak of. Installing this in the shower, there’s a consistent supply of hot water, which is impressive since the Eco 8 is so compact.

Now for the downsides, the efficiency of this water heater will depend on where you live. This heater is best for those who live in condos or apartment but not advisable for larger homes. This is the reason why some users complain that the Eco 8 is not warming the water as efficiently. Simply put, it’s not the kind of water heater that can truly supply hot water to all rooms in a large house.
