The cost of electricity fluctuates depending on how much of it is being used at any given time. ETS Water Heaters take advantage of this by drawing electricity during times of low demand (such as overnight), when it’s less expensive.

They use this bargain electricity to heat the water stored inside their Envirofoam®-insulated tank, which allows only 5ºF of heat loss in 24 hours. With this innovation, you’ll have hot water whenever you need it, for less.

Guaranteed to last

ETS Water Heaters are easy on electricity, but that doesn’t mean they’re not tough. Built here in the U.S. with water-tight polyethylene materials, they resist damage and rust in any environment.

On average, a water heater needs to be replaced every 10 years. But the ultra-durability of these ETS Water Heaters is backed by a lifetime warranty, leaving you with fewer worries, and more peace of mind.

Easy, professional installation

Lightweight yet heavy-duty, ETS Water Heaters can be installed without the need for special equipment. This reduces the time, cost and headache of getting your water heater up and running.
