Tankless Point-of-Use Water Heaters, 1 and 2 GPM

These small tankless heaters are primarily electric, although a few models are powered by propane. The electric models can be very tricky to install, so figure in that cost if you are not an experienced DIYer who is confident in your electrical abilities.

Eccosmart makes indoor and outdoor propane and electric models in this range. It has a 1.4 GPM heater for outdoor shower usage that is powered by propane and ignited by only 2 D cell batteries. Another Eccosmart model heats up to 2 GPM and is powered by electricity, enough for one low-flow shower and one sink.

Bosch has 1.2 GPM, 1.5 GPM and 2 GPM electric models for indoor usage. The smaller models are recommended for sink applications and are reported to only give short hot showers if used in that way. They also can be a bit difficult to install.

Marey’s 2 GPM model powered by propane is manufactured for use in small apartments with only one shower. Some people use it for hot tubs as well.

Stiebel makes a 2.4 GPM model that can also handle one shower and one sink. Stiebel has a sterling reputation when it comes to tankless heaters, consistently drawing high praise.

Ariston also offers a model under 3 GPM, with its 2.75 GPM GL 25 brand.
