Advantages to Installing a Tankless, Rinnai Ultra Water Heater Over a Traditional Water Heater

by | Feb 16, 2020

If you have ever felt the shock of ice-cold water hitting you in the shower, you understand the need for a dependable water heater. As simple as heating water for your home or commercial space might seem, selecting the water heater best suited to your particular needs can be complicated. Among the top models in this broad market is the Rinnai Ultra Water Heater. Tankless or on-demand water heaters provide hot water only as needed, which eliminates the need for a storage tank and reduces the standby losses related to maintaining the temperature of a full tank while it is not in use.

Whenever you turn on the hot water tap, it draws cold water into the tankless unit. The cold water circulates through a heat exchanger, heating the water, and then providing hot water to the open tap. The hot water in tankless water heaters never runs out, but sometimes there are limits on flow rates, which range from 2 to 10 gallons per minute (GPM), depending on their design and heating capacity.

Tankless Water Heater Types

There are two basic types of tankless heaters, smaller units, used near the point-of-use, and lager, whole-house units capable of serving an entire house or commercial space. Smaller groups are useful in applications where hot water need is isolated to a single area, like a bathroom or kitchen in a warehouse. Whole-house units serve as an alternative to traditional tank-type water heaters in applications with hot water needs throughout the house or commercial space.

Benefits of On-Demand Water Heating

On-demand water heating presents some significant advantages over traditional storage-tank style units, making them a better fit for a variety of residential and commercial installations.

Higher Efficiency

Though tankless water heaters often come with a higher upfront price tag, they provide superior energy efficiency. Tank-style units require the periodic use of fuel or energy to maintain the temperature of hot water inside the storage tank, a.k.a. standby losses, wasting energy while heating stored water. On-demand water heaters eliminate standby loss, making them more energy-efficient.

Greater Longevity

Storage tank-style water heaters have a typical service life of between 10 and 15 years, depending on the quality of the model. In contrast, tankless style water heaters have greater longevity, providing a service life of 20 years or more, twice as long as tank-type heaters in some instances.

Space Saving

The elimination of the need for a storage tank allows for the installation of tankless heaters in limited space. Their compact size allows for installation in a hallway, porch, closet, attic, or crawl space where a storage tank unit would never fit.

No Waiting for Recovery

When there are a lot of people in the house, or specific activities use up a lot of hot water, tank-type units tend to run out, just before your shower. On-demand water heaters eliminate the issue of waiting for hot water recovery by providing an unlimited water supply. This characteristic of tankless water heaters allows households to run multiple showers and appliances simultaneously while providing dependable hot water.

Cost Savings

Cost-effective water heating provided by on-demand heaters comes in several forms. Through the elimination of standby losses, there is a 10 to 15 percent energy cost reduction provided by these units. Additionally, tankless units have a longer service life, almost twice as long in some cases, saving money on replacement costs over time.
