Condensing Boilers

Highly-efficient condensing boilers from Bosch.

Highly-efficient condensing boilers from Bosch deliver reliable heating and hot water with high efficiency and low operating costs. Condensing boilers convert water vapor condensation into heat, recycling waste gas. This process allows these systems to deliver 95% energy efficiency on average, as well as use less fuel than traditional boilers. Bosch also offers combi condensing boilers, which provide hot water in addition to heating. All Bosch condensing boilers are small and lightweight, with wall-mounted and floor-mounted options for easy installation.
