Install new navien npeA2 tankless water. The tankless water heaters offer endless hot water and an internal recirculation system allowing hot water to get to fixtures quickly. In this quote it invades removal of the old Romani tankless unit and installing a new navien tankless. We would rework all copper and gas lines running to the new unit. We would also use a termination kit for the venting to ensure a clean look on the outside of the unit. This quote also includes an ion 6 conditioner. This addition is optional but highly recommended as it has a 25 year warranty and extends the life expectancy of the unit. This new unit would also require the installation of a gas regulator and an upgraded gas meter to a two psi system.
