A Rinnai tankless water heater works by heating water as it passes through the unit on the way to the hot water tap. A flow sensor in the device senses water movement and starts the gas or electric heat source to increase the water temperature.Continue Reading
Rinnai tankless heaters increase the temperature of water that flows into the unit to the set temperature. When the incoming water is warmer, the temperature rise decreases, and the flow capacity of the unit increases. However, when incoming water temperatures drop, the temperature rise increases and the unit is unable to supply as many taps.
Rinnai offers both gas and electric tankless water heaters. Rinnai supplies conversion kits that allow the conversion of tankless models between propane and natural gas, but it requires a qualified technician to order and install the conversion kits.
Like tank style water heaters, the distance between the hot water tap and water heater determines the time it requires for hot water to reach the fixture. In a typical home, a water heater, installed 50 feet from the tap, requires about 1 1/2 minutes for the water to reach the sink. Homeowners can eliminate their wait by installing multiple point-of-use tankless units under distant sinks.Learn more about Appliances
