Each year on April 22, more than a billion people worldwide celebrate Earth Day, making it one of the world’s largest civic observances. Founded in 1970, Earth Day raises awareness for creating a more eco-friendly world.
Here at Rinnai, we celebrate Earth Day every day by developing innovative products that save water and energy in homes and businesses.
One of our most precious natural resources flows through our rivers, lakes, oceans, and of course, our plumbing systems. Rinnai tankless water heaters are designed to efficiently heat and conserve water in a way that keeps it flowing in all the right places.
Rinnai enforces the “play smarter, not harder” rule with its breakthrough recirculation technology featured in its Ultra Series Tankless Water Heater RUR models. Delivering our most energy-efficient performance, the RUR features a condensing design with two heat exchangers to maximize heating value to enhance reliability and durability and reduce maintenance. Standard features of the Ultra Series RUR include an Energy Factor of up to .96, ENERGY STAR® certification and faster hot water provided by integrated recirculation pump and internal bypass line with or without a dedicated return line.
In a home or office with many hot water demands, our recirculation system makes hot water available faster, wherever and whenever you need it. In other words, no more water running down the drain while you wait for hot water.
Rinnai tankless water heaters are also incredibly energy-efficient. Unlike traditional tank water heaters that keep a large reservoir of water hot continuously, tankless water heaters only heat the water as it’s needed (and as long as it’s needed) - reducing energy consumption up to 40 percent.
In addition, Rinnai tankless water heaters operate at or above the Department of Energy’s (DOE) Energy Factor (EF) standard. In 2015, the DOE increased the EF rating for most water heaters. The change didn’t come close to affecting Rinnai tankless units. In fact, our high-efficiency tankless water heaters operate at .96 EF, far exceeding the requirement.
For many, Earth day is not just about celebrating once a year, but making sustainable choices every day. With tankless water heaters, customers achieve peace of mind in knowing they’re choosing sustainable, Earth-conscious products year-round.
