I wanted to give a shout out and a big thank you to Mike and his team @DeMark Home who installed my tankless water heater today.<br><br>Mike was really helpful and went above and beyond to answer all my questions and the entire thing went seemlessly. The two service men that came to install were friendly, polite and very professional.<br><br>In addition to installing the new tankless water heater, they also replaced the valve for my furnace humidifier, updated the gas fittings so everything is
