Endless Hot Water for One Sink at a Time
Compact point-of-use / under-sink tankless water heaters are designed
to provide an endless supply of hot water for kitchen and bathroom
sinks. These units provide 98% efficiency with minimal stand-by loss
and most models are equipped with high/low kW settings.
Note: All Bosch Tronic 3000 models require hard wiring.
Example: An inlet water temperature of 55°F and a desired water temperature of 120°F requires a temperature rise of 65°F.
*Specs are based on 240 V. Lesser voltage (220 V or 208 V) will result in reduced output. Values shown are for high / low kW settings.
