Every major tankless water heater manufacturer has a 199,000 BTU condensing tankless water heater. The reason: anything over 200,000 BTUs will not qualify for the coveted Energy Star label.
The entire tankless industry has moved from non-condensing to condensing tankless water heaters due to the high efficiencies and low cost for PVC or polypropylene venting. So, how do you pick the best condensing tankless water heater from such a crowded field?
Bosch has long been the industry leader in condensing tankless water heater technology. And right now is a very exciting time to purchase a Bosch Tankless Water Heater because of the current offerings that include water connections on either the top or the bottom of the water heater.
Competitors:
Navian offers a few condensing models and are high efficiency units but all have the water connections on the bottom making it a lot more difficult to replace a standard tank heater as the water connections are on the top of the tank. Some of the Navian condensing models are the NPE-a and the NPE-S series.
Rinnai has a few high efficient condensing models also such as the RUCS series but also have the same bottom water connections making it more difficult to replace a standard tank heater.
Most installers will go with the Bosch Greentherm 9000 series for new installations because of the time saved with top water connections.
