Unlike typical hot water boilers, an on-demand tankless gas heater from Noritz America takes up little space. But Fung + Blatt also likes the unit's efficiency. Traditional boilers heat water constantly; tankless systems heat water only when it's needed, which may reduce monthly water-heating bills by up to 50 percent.
