Rinnai Electric Tankless Water Heater: 1 of 2 Demand-Type Appliances

Rinnai electric tankless water heater


The story of worldwide Rinnai success started in 1920 in Japan, from manufacturing oil cooking stoves.

After that the Company products expanded into numerous gas appliances and space heaters. But since 1964 Rinnai units have begun heating water.

Today, this is a global residential and commercial appliance producer, with a network in 13 countries.


Every homeowner can value either a Rinnai electric tankless water heater or a gas variety model.


What's the difference and which one is right for you?



Rinnai Electric Tankless Water Heater vs. Rinnai Gas tankless Water Heater

  1. Tankless water heaters are also known as 'demand-type' water heating appliances. That said, they provide as much hot water as it's actually needed. Consequently, there are no standby energy losses, which are commonly associated with all those storage water heaters. Finally, you save plenty of money with both of Rinnai.
  2. How does each of them work? The water is heated directly, with no use of any storage tank. When you turn on a hot water tap, cold water starts traveling into the unit through a pipe. But this is either (1) a gas burner or (2) an electric element that heats water. Whatever the case, tankless water heaters offer a constant hot water supply.

  1. However, the flow rate is limited by the actual output. Thus, a gas-fired tankless water heater from the Company can produce higher flow rates than a Rinnai electric tankless water heater. Though sometimes, even the largest gas model cannot supply too much hot water for multiple uses in very large households. To overcome this problem, most homeowners install more heaters or just separate heaters for different appliances.
  2. Both tankless water heaters avoid the standby heat losses. But gas-fired models can waste energy if having a constantly burning pilot light. Anyway, you may always turn it off when not using. Alternatively, consider the models with an intermittent ignition device instead of that standing pilot light.
  3. Except the fuel type and energy efficiency, you need considering the size and costs, before buying any tankless water heater.
  4. Proper installation & maintenance of your demand-type water heater depends on many factors, including fuel type, climate and building code requirements. Concerning gas-fired models, safety issues play an important role. Therefore, a Rinnai electric tankless water heater is considered safer. Speaking of periodic water heater maintenance, this can significantly extend any device longevity and minimize its efficiency loss.
  5. Generally, these two varieties cannot be replaced. As for the electric tankless water heaters, they tend to deliver hot water not fast enough, if the groundwater is too cold and even warmer. Thus, most homeowners need upgrading electrical service, in order to supply necessary amperage.

In short, it depends. Only you decide, whether electricity or gas should assist your own Rinnai tankless water heater!
