In general, the purchase and installation costs of a tankless water heater can be 2 to 2 1/2 times as much as a conventional tank-style water heater. However, energy savings with a tankless water heater typically result in a payback within just a few years for a family of four, making a tankless water heater a better long-term investment.
Rinnai tankless water heaters reduce energy consumption by up to 40%. They heat more efficiently and only heat water when it is needed, avoiding standby loss.
The compact design of a Rinnai tankless water allows flexible installations located closer to fixtures and appliances. This reduces the wasted water while “waiting” for the heated water to arrive.
The service life of a Rinnai tankless water heater lasts up to 20 years. That is 2-3 times longer than traditional tank water heaters. They are also significantly smaller in size, using less materials and reducing what may end up in landfills.
With a Rinnai tankless water heater, you’ll have peace of mind with an industry-leading 12-year limited warranty on the heat exchanger. And, effective April 1, 2011, Rinnai now offers extended limited warranty labor coverage of up to 5 years from the date of purchase on select models of Rinnai tankless water heaters when used in a residential hot water application.
