1. Lowers Your Energy Bill
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.

2. Conserves Water
The compact design of a Rinnai tankless water heater allows flexible installations located closer to fixtures and appliances. This reduces
the wasted water while "waiting" for the heated water to arrive.

3. Buy Only Once
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 material and
reducing what may end up in landfills.


  1. When opening a hot water tap, or starting the dishwasher, the Rinnai tankless water heater recognizes the need for hot water and starts the heating process.
  2. The temperature of the incoming water is used to calculate how much heat the burners must produce to deliver water at the desired temperature.
  3. When the demand for hot water ceases, the unit shuts down and uses no energy, waiting until more hot water is needed.
  4. The end result is hot water that is not limited to what's available in your tank. You always have clean, hot water when you want it for as long as you need it!

In general, the purchase and installation costs of a tankless water heater can be 2 to 2.5 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.
