INDUSTRY'S FIRST
Simultaneous Operation of Domestic Hot Water and Heating
Most combination boilers prioritize the call for hot water while your home is being heated. This causes your home heating to go cold while things like the shower are running.
The NRCB is the industry’s first to be able to handle both simultaneously to provide ease and comfort.
