DESIGNED SPECIFICALLY FOR HEATING HOMES

Noritz is the first tankless water heater manufacturer to introduce tankless hydronic boilers.  The NH Series consists of two models, the NH199-DV and NH150-DV.  Both of these direct vent models provide quiet and constant heat to your home by providing hot water to applications such as cast-iron radiators and baseboards.  These units share the same features as with our other heaters - space saving, energy efficient, and environmentally friendly.  They are capable of offering nine temperature settings and is fully-modulating, meaning energy is used efficiently.  These tankless hydronic boilers are significantly smaller in size, weighing in at only 66 pounds vs conventional boilers' which typically weigh more than 300 pounds, giving your home more space to enjoy.
