Tankless Units in Normal Homes
Most Normal homes keep the tankless in the basement near the floor drain. Harsh winters, snow at the vent and hard water all leave their mark.
What we run into in Normal
- Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
- Snow on vents. After a big storm, a buried intake or exhaust is one of the first things to check when the hot water quits.
- Hard water. The water here carries a lot of minerals, and they settle as scale inside the heat exchanger. LC codes, overheat faults and water that will not get hot often trace back to it.
