    Rinnai has been delivering nothing but the best for almost 100 years and that award-winning dedication can't help but be noticed in its SE Series. The RUCS75IN and all of the SE Series models offer Rinnai's incredibly efficient condensing design line of tankless heaters. Rinnai's SE Series models utilize two premium heat exchangers to provide optimal reliability and durability. With a 0.90 Uniform Energy Factor and a sleek, innovative design, the RUCS75IN is the ultimate option.
  • Compact Design Saves Space
  • The RUCS75IN is designed to be able to be installed on any wall or in any compact space, including non-traditional places like an attic or crawlspace that hides your unit and frees up valuable space in your home.
  • Energy-Efficient Promise That Saves You Money
  • Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves resources by only heating water when you need it, while an electric ignition avoids the constantly wasted energy of a standing pilot light.
  • Continuous Water for Multiple Applications
  • You should be able to have two people shower at once or do the laundry while the dishwasher is running. Rinnai tankless water heaters provide an endless supply of hot water that remains uninterrupted, even when you're the last one in line for the shower.
  • Product Includes
  • (1) MC-91-2 temperature controller (Integrated into indoor models)

Hot Water
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Condensing
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
