Bosch

CEC out of Vt. markets Bosch gas fired powerventable waterheaters. Just received a brochure from them the other day. Try www.controlledenergy.com/12 or 1-800-642-3199 the brochure has no info about convertability as gas source

\"Bosch\" Brand label

There are (at least) two tankless products with the Bosch brand on it (CEC does market both). First is the "Bosch Aquastar" with non modulating fixed BTUH output. The second is a re-branded Takagi TK1 fully modulating 35K-165K output. Very different animals. I know the Takagi literature states the unit is not field convertable between LP & NG.

I installed on of them 5 years ago as a wall hung boiler. It was not feild convertable I remember this becouse I had to send the first unit back to the supplier. I don'y remember the model number but it worked like a charm. Very good piece of equipment. On draw back is they like the gas. Make sure to supply it with correct pipe size.
