Vitodens 100-W FAQ
What is a combination boiler?
A combination boiler provides both space heating and domestic hot water from one appliance. The Vitodens 100-W B1KE-120 heats domestic water on demand through an integrated plate heat exchanger, eliminating the need for a separate hot water storage tank.
How much hot water can the Vitodens 100-W B1KE-120 produce?
The B1KE-120 provides up to 3.3 GPM of continuous domestic hot water at a 77°F temperature rise. Actual hot water flow depends on the incoming water temperature and the required outlet temperature.
Is the Vitodens 100-W B1KE-120 suitable for a home with high hot water demand?
The B1KE-120 can provide continuous hot water as long as the system's demand stays within its 3.3 GPM DHW flow capability. Homes with multiple simultaneous high-flow fixtures may benefit from a higher-output combination boiler or a boiler paired with an indirect storage tank.

Does the Vitodens 100-W need a separate water heater?
No, the B1KE-120 produces domestic hot water on demand through its integrated plate heat exchanger, so a separate storage water heater isn't required. This helps save both equipment and mechanical room space.
How efficient is the Vitodens 100-W B1KE-120?
The B1KE-120 has a 95% AFUE rating and a 10:1 turndown ratio. Its modulating condensing design allows the boiler to reduce its firing rate as demand decreases, helping improve efficiency and reduce short cycling.
