Is the Bosch 125B a good water heater?
The 125B is not an appropriate model for warm input water, such as that from solar hot water panels. There are other models for that. This unit is a real jewel. I have installed two of these units and have found them to be excellent water heaters.
How big of a gas line does a Bosch 125B need?
The 125B needs at least a 3/4 inch gas line, wider if it is a long run or several gas appliances will be running at the same time. Also, on-demand heaters require at least a five inch flue. The three inch flue used with tank water heaters is not sufficient.
Can a Bosch 125B be used with two shower heads?
The 125B is not intended for two hot water uses at once. For that get a bigger model or install two. The 125B probably also works best with low flow shower heads, at least in places with cold water, because the hot water flow can be fairly slow when the incoming water is quite cold.

Can a Bosch 125b-ng be mounted in a closet?
A boon for basement-finishing plans, the 125B-NG takes up much less space than a tank heater and can be mounted in a closet or on a wall on included hooks. The unit is designed to vent vertically, but the optional AQ1 kit allows you to vent it horizontally through a wall.
