Electric Tankless Water Heater Reviews

Electric tankless water heaters might be the hottest segment in the entire water heater market, judging from the number of manufacturers that are jumping into the game.

Consumers love the idea that they are only paying for electricity to heat hot water when they actually need the water, not when they are sleeping or away from home on vacation. They see the results immediately as their electricity bills dip in response to having on demand heaters installed. Some start out with one small tankless heater to see how it goes, then end up installing other heaters all around the house or opt for a larger model that can supply hot water to other sources without a problem.

The downside of these little wonders is that they can be very complicated to install and to fix. Some reviewers say that these marvels should be considered computers that heat water, with the resulting possible bugs coming into play.

Some DIYers are able to install electric tankless heaters with no problem; many other consumers buy them and then realize that they need to reconfigure their entire power capabilities for their house.

Needless to say, people that want to power an outdoor shower, a summer cabin or a small apartment adore their tankless heaters. They take up little room and produce a very small bite when the electric bill comes in the mail.
