Direct-vent indoor tankless water heaters pull 100% of their combustion air directly from the outside through a dedicated intake pipe and exhaust combustion gases through a separate pipe. This sealed combustion design prevents backdrafting and allows safe installation in tight utility closets and living spaces. In Country Club Hills, Illinois, our technicians repair direct-vent systems. We fix cracked intake pipes, seal exhaust joints, replace air pressure differential switches, and clear intake terminal screens so your indoor unit operates cleanly and safely.
