Point-of-Use Tank Water Heaters, up to 10 and 20 Gallon

Heaters of this size are also called “point of use” heaters because they are installed near a sink or shower and they are uniformly powered by electricity, not gas. Thus, they might have a higher bill per month but they can be used to target a specific area in your home that needs hot water fast.
These small heaters are compact enough to fit into tight spaces where large tanks cannot go. Most models are a little over two feet tall and less than two feet wide.

Rheem and Reliance make 10- and 20-gallon water heaters that have tanks and can be used for many different applications that require less capacity.

The Reliance 10-gallon “short” heater comes with a six-year warranty and is a relatively new entry onto the market. Reliance’s 20-gallon model does not cost much more and can heat up double the water. Both are said to be very easy to install.

The same praise has been dished out for Rheem’s 10-gallon and 20-gallon models. Both brands have over-temperature protectors that will cut off power in “excess temperature situations.” Rheem’s small water heaters are priced above the Reliance models; you will have to do the proper research and read our reviews to determine whether or not that higher cost is justified.
