Rod and Ryan just completed the installation of a new tankless water heater in my (very small, short ceilinged) basement. Installation day was seamless and other than a few hiccups caused by factors outside of anyone's control, the whole process was flawless. Rod selflessly took on handling all of the communication with BGE and the city and coordinated all appointments which made my end of this very easy and roughly "please open the door at this time." They're a smaller outfit but the basement was clean when they left, everything works, they walked us through how the system works and what maintenance is required and I feel good that we're going to have a nearly endless supply of hot water going forward. Highly recommend.
