This Tankless Guide overview will help you decide what size electric tankless water heater you need for your purposes, and provide links to some of the best electric models for 2012.

Point of Use Electric Tankless Water Heaters

Most electric tankless models are designed to serve just one location, with flow rates of 1.0 to 2.5 gallons per minute (GPM). These point of use units are ideal for bathroom sinks, dishwashers or clothes washers, a utility tub or jetted tub, or a single shower. Point of use models are more efficient than whole-house models in one sense – no hot water is left in long runs of pipe to cool off. There’s almost no waste with these, and most point of use electric tankless heaters work with low-flow fixtures very well, so you can conserve water and electricity very well. Units in the 2.0 to 3.0 GPM range can be installed to serve an entire bathroom, a laundry room that also has a utility tub, or similar locations with 2 water points.

Whole House Electric Tankless Water Heaters

With a growing demand for large-capacity electric models, there are now more whole-house units available. With up to 5.0 GPM, the largest can be installed in 1-2 bedroom homes where hot water is often in use at 2 points. Larger homes or very busy households with high demand for hot water will still need a gas-fired whole house heater since they have capacities over 10 GPM.

A whole-house unit is installed in a central location. It feeds the entire home or zone it will serve in the same way traditional water heaters do. They can be a more cost-effective choice for 2-3 application points because one large unit costs less than 2 or 3 small ones in many cases.
