Bosch is know for making some of the highest quality products, ranging from power tools, windshield wiper blades, and home appliances. Bosch’s thermotechnology division  falls right inline with Bosch’s other quality products.  Bosch Thermotechnology Corporation makes geothermal heat pumps, gas and oil boilers, solar thermal systems and tankless water heaters. Bosch makes multiple gas and electric tankless hot water heaters.

Their gas line has an impressive line up with energy factor ranging from 0.78 all the way up to 0.98, on of the highest among all manufactures. They are certain to have a size which will fit your needs with a max BTU ranging from 75,000 BTU up to 225,000 BTU Bosch offers and amazing 15 year warranty on their heat exchangers and a 3-5 year warranty on other parts, depending on the model.

The Bosch Greentherm line offers a fully modulating gas value to make it one of the most energy efficient tankless water heaters on the market. Also this line has a new venting system which requires only one 5” wall penetration. Also, if you are running multiple tankless water heaters, they can be vented on one common vent, limiting the cost of installing multiple units. These units are also Energy Star Qualified, which may qualify for federal, state and local rebates.

One of the more interesting things that Bosch offer offers is their Patented Hydro-power ignition. This tankless model does not need to be connected to electricity. Also there is no standing pilot. A small turbine uses the energy from the flowing water to ignite the burner. This unit is a great idea when it would be cost prohibitive to run a new electric line and/or in regions which are prone to power outages from inclement weather.

Bosch also has units which can be installed out doors. Some of these units will need a cold weather kit. Finally, worth noting is the electric water heaters line that Bosch also offers. They have 2 whole house options and a mini tank point of use option.

Bottom line, Bosch, like all of its products, makes great tankless water heaters. They have a wide selection of models to choose from, which should meet any homeowners needs.    .
