In this article, we will explore the benefits of tankless water heaters, discuss the savings offered by condensing heaters, and delve into the advantages of recirculation systems.

Additionally, we will take a closer look at Rinnai's new RSC199 tankless water heater, highlighting its features, including the built-in recirculation system and smart pump.

Furthermore, we will touch upon the importance of warranty and quality, emphasizing the reliability of the Rinnai brand. Lastly, we will guide you on purchasing this innovative product from a certified E-Tailer like Big Frog Supply.


Understanding Tankless Water Heaters

What are tankless water heaters?

Tankless water heaters, also known as on-demand water heaters, are compact units that heat water instantaneously as it passes through the device.

Unlike traditional water heaters with storage tanks, RSC199 do not store and continually heat a large volume of water.

Instead, they heat the water only when needed, delivering a constant supply of hot water on-demand.

This efficient design eliminates the energy losses associated with standby heat loss, which occurs when stored water gradually loses heat over time.

Benefits of tankless water heaters

  • Energy efficiency: Tankless water heaters are highly energy efficient since they only heat water when it is needed. This feature significantly reduces energy consumption compared to traditional storage tank heaters.
  • Endless hot water: With a tankless water heater, you no longer have to worry about running out of hot water during long showers or when multiple household members need hot water simultaneously.
  • Space-saving: Tankless water heaters are compact and can be mounted on walls, freeing up valuable floor space that would otherwise be occupied by a traditional water heater with a storage tank.
  • Longer lifespan: Tankless water heaters generally have a longer lifespan than traditional models, potentially lasting up to 20 years or more with proper maintenance.
  • Reduced risk of leaks: Since tankless water heaters don't have storage tanks that can deteriorate over time, the risk of leaks and water damage is significantly reduced.

The Advantages of Condensing Water Heaters

How do condensing water heaters work?

Condensing water heaters are a type of tankless water heater that utilizes advanced technology to maximize energy efficiency.

They achieve this by capturing and utilizing heat that would typically be lost in non-condensing tankless models.

The exhaust gases in condensing heaters are cooled to the point where they condense into water, releasing additional heat energy that can be used to heat incoming cold water.

Energy efficiency and cost savings

  • Higher efficiency: Condensing water heaters offer higher energy efficiency compared to non-condensing models. The condensing process allows these heaters to extract more heat from the combustion gases, resulting in increased efficiency.
  • Lower energy bills: The increased efficiency translates into reduced energy consumption, leading to lower monthly energy bills and long-term cost savings.
  • Environmental friendliness: The reduced energy consumption of condensing water heaters contributes to lower greenhouse gas emissions, making them a more environmentally friendly choice.

Exploring Recirculation Systems

What are recirculation systems?

Recirculation systems are designed to provide instant hot water at the tap by eliminating the delay typically associated with waiting for hot water to reach the desired temperature. These systems circulate hot water from the water heater to the faucets, ensuring hot water is readily available whenever needed.

Instant hot water and water savings

  • Immediate hot water: Recirculation systems eliminate the need to wait for hot water, providing instant hot water at the faucet. This feature is particularly beneficial in homes with large families or during busy mornings when multiple people need hot water simultaneously.
  • Water savings: Recirculation systems can save a significant amount of water that would otherwise be wasted while waiting for hot water to arrive at the faucet. This not only conserves water but also reduces utility costs.
