15 YEAR PROTECTION!
    Bosch's heat exchanger is so well built, it's backed by the longest protection plan you can find - 15 years. Bosch delivers years of trouble free performance. It can be the last water heater you ever buy.
 
The pilotless Bosch Model 425 HNL
    Bosch has developed a new, patented hydro-generator ignition system that requires no standing pilot, electricity or batteries. When water flows through the 425 HN's hydro generator it spins a tiny turbine which produces the spark required to light the burner. All other specifications are the same as the Model 425 PNL. 

New!

    We will soon be offering the Rinnai direct vented tankless hot water heater. This is a power vented model, similar to the Bosch 425 EFL, but it uses outside air for combustion. A very nice unit. Call for details.
 

 

                            The Bosch ProTankless gas hot water heater is one of the most efficient ways to heat water available today. This rugged compact unit will pay for itself in about five years with the LP gas saved from not using a conventional hot water heater. The Bosch is wall hung (a fire-proof wall is not needed) - a cellar chimney is the most likely place to hang it. It requires open space to the front, 6" clearance on either side and 12" clearance to the ceiling. It is plumbed with 1/2" copper pipe for water inlet and outlet and requires at least a 5/8' diameter LP gas pipe. (Model 425)
    The Bosch also requires a 5" vent pipe easily adaptable to 6". This vent should be thought of as the same type of vent necessary for a wood stove - not simply a 5" diameter pipe leading horizontally to the outside. The Model 425 HN requires a 5" diameter "B" type vent at least 11' high. The Model 425 EF comes complete with its vent hood to the outside, but needs 4" single wall stainless or galvanized pipe from the unit to vent hood.
    We have sold many tankless water LP gas water heaters locally and our neighbors love them. Their economic operation and endless supply of hot water make the Bosch a favorite with everyone!
