A Complete List of Tankless Water Heater Manufacturers

The popularity of tankless water heaters in recent years means a lot of old and new manufacturers have grown in importance. Some companies have made tankless water heaters for years, while others have only recently started.

Either way, here is a complete list of all the brands of tankless water heaters you have to choose from:

Rinnai is by and large the best-selling tankless water heater in the U.S. Their gas-fired water heaters feature a commercial heat exchanger and are backed up with a comprehensive warranty.
Rheem offers gas, electric, and point-of-use tankless water heaters. They have a wide variety of offerings for residential and commercial use, and a U.S.-based customer service team for product questions.
Noritz provides water heaters that come with a low carbon footprint under the Eco Tough line, and commercial-level durability in the Pro Tough model. Their Value Solutions brand is specifically designed for smaller homes and warmer climates too.
American Water Heaters manufactures gas-powered tankless water heaters in condensing, indoor, and outdoor models. Many of their heaters are useful for smaller homes and apartments.
Navien tankless water heaters use stainless steel heat exchangers and are typically gas-fired. They too offer condensing and non-condensing water heaters.
Girard makes tankless water heaters specifically for use in RVs and campers. Their RV-focused water heaters offer the choice to flip between three temperature settings – hot, normal, and cold – which changes to which temperature the water will heat. Their heaters work on an induced draft, which means a blower fan forces hot air through the heat exchanger.

Eccotemp excels at portable water heaters for the RV or campsite, with a particular strength in outdoor showers. They also offer residential water heaters for outdoors installation.
