EcoSmart Eco27 heats water quickly

Bought this tankless water heater as a replacement for another one I had installed in 2017 that started leaking around the solder joints and quit heating the water. Walmart's price was better than other stores. Although the price was about double from 2017. Installed the EcoSmart Eco27 the same day as received and have hot water again. Water heats up quickly and it's great to not have to take cold showers anymore.

Excellent choice

I was not sure if this was the correct purchase for our household, but it has proven to be one of our best decisions. Temperature of hot water is consistent and everyone enjoys a nice hot shower.

Accurate description. Fast delivery. Same price as Home Depot and much quicker delivery. Need professional electrician to install it- requires (3) dual 40 amp circuit breakers. Very compact device.
