Does Rinnai manufacture an electric tankless water heater?
We do not make an electric model. This is for two reasons, first the power requirements of electric units large enough to provide hot water for a typical household are prohibitive. For example a unit that can provide 3 gallons per minute with an 80° F temperature rise would require about a 150 amp 230VAC circuit. This is about 8 times the power required for a 3 ton central air conditioning system. Second, the relative operating cost of electric tankless is MUCH high than natural gas. Based on national averages electricity costs almost twice as much per BTU as natural gas. Even with propane gas, tankless is considerably less expensive to operate than electric.
