About Bosch High-Efficiency Boilers
Bosch high-efficiency condensing boilers are 95% energy efficient, resulting in substantial energy savings for homeowners and facility managers.
The Greenstar boiler line from Bosch offers both heating-only and combi models. These units are built compactly to save space and come in both floor-standing and wall-hung designs. They also include a fully modulating fan that adjusts to heating demand, and they are insulated for ultra-quiet operation.
How Does a Condensing Boiler Work?
Condensing boilers use a secondary heat exchanger to collect heat from exhaust gases and repurpose it to preheat incoming water. Learn more in our condensing boiler buyer's guide.
