BEST ELECTRIC TANKLESS WATER HEATER - 2017

Electric tankless water heaters are the future of household water heating systems. They are easier to install than their gas counterparts and come cheaper on the long run, especially with electricity prices being far more stable and consistent than gas prices. In short, electric water heaters use electricity to heat up the incoming water flow. Basically, the water flows through the preheated water heater and it gets warmer as it goes through it, leading to hot water on demand anywhere in your household. Tankless electric water heaters are much smaller than the tank heaters, and even than the tankless gas heaters.

They are also safer, with a longer lifespan and require less maintenance. Sure they cost a bit more at first, but their value distributed throughout the years of usage will be much less than a regular heater. Usually a family of three can easily use only one electric heater without having to sacrifice water time, although a bigger family will probably have to install more than 1 small electric heaters, or just one but bigger.

So if you’ve already made up your mind you will probably be lost in the vast ocean of water heaters by now. It is important to choose the perfect water heater for you and we know that, so we’ve handpicked five of the best electric tankless water heaters for you. The final choice, though, still lies onto you, so buckle up, as we are about to go through the choices for your new water heater!
