The tax credit for qualifying energy improvements such as the installation of Rinnai tankless water heaters, is 10% of the full purchase and installation price up to a maximum credit of $300.

For more information on the bill, check out the U.S. Department of Energy website.

2. Rinnai Offers New Condensing Water Heaters and Boilers

This fall Rinnai Corporation has released new produces featuring high efficiency condensing technology.

First, Rinnai has added 4 new condensing gas tankless water heating models. These new units feature the operational benefits of their current tankless water heater line including continuous hot water, but also provide improved energy savings and environmental benefits. Rinnai's condensing water heaters are Energy Star qualified and deliver efficiencies up to 96.5%.

There are two models designed for exterior use, and two interior models. Interior models feature an innovation pipe in a pipe venting system featuring a durable polypropylene inner flue.

Second, Rinnai has entered the hydronic heating market with it's new line of condensing wall mounted gas boilers. These gas fired models are capable of providing both heat and hot water to an entire home at efficiencies as high as 96.5%.

Rinnai boilers include two series and a total of seven models. The E Series is design for homes with smaller domestic hot water requirements.The Q Series is design to provide space heating and hot water in home with high hot water loads.

3. ENERGY STAR To Increase Minimum Gas Water Heater Efficiencies

This fall, the ENERGY STAR® program will increase the minimum Energy Factor (EF) for gas storage water heaters from 0.62 to 0.67. The increase in criteria, which will go into effect on September 1, 2010, will bring additional 0.67 EF models to the marketplace, offering homeowners even greater water heating efficiency.

"ENERGY STAR seeks to keep its product criteria relevant by keeping pace with changing technologies in the marketplace," said Steve Ryan, with the ENERGY STAR program at the Environmental Protection Agency. "In a recent poll, 77 percent of people are aware of the ENERGY STAR label and see the value in it. We work to keep the brand meaningful by making sure it continues to indicate cost effective savings with no loss of amenity. Storage water heaters are becoming more efficient, and this change recognizes that fact."

Water heaters that meet the increased criteria offer homeowners significant savings in gas consumption even when compared to today's 0.62 EF models, providing up to 14 percent greater savings than a conventional gas model. According to ENERGY STAR calculations, 0.67 EF models only consume 224 therms per year. Gas storage heaters with a 0.62 EF consume 242 therms annually, saving up to 7.3 percent more than a conventional model.

Several gas storage heaters with a 0.67 EF are currently available, including many new products recently developed in preparation for the upcoming change. There are also a number of other water heater models that carry the ENERGY STAR label, including electric heat pump, solar thermal and tankless units. Sponsors of the Coalition for ENERGY STAR Water Heaters (CEE)—A. O. Smith, Bradford White, Rheem and Rinnai—offer many of these models.

Plumbers can check with their distributors and local utilities on the availability of new 0.67 EF gas storage models and rebate offers in their area. Visit the Coalition online for more information on local utility rebates and other water heating efficiency news at

About CEE:

CEE is an award-winning consortium of efficiency program administrators from the United States and Canada that unifies program approaches across jurisdictions to increase impact in fragmented markets. By joining forces at CEE, individual electric and gas efficiency programs are able to partner not only with each other, but also with other industries, trade associations, and government agencies. Working together, administrators leverage the effect of their ratepayer funding, exchange information on successful practices and, by doing so, achieve greater energy efficiency for the public good.

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. Today, the ENERGY STAR label can be found on more than 50 different kinds of products, new homes, and commercial and industrial buildings. Products and buildings that have earned the ENERGY STAR designation prevent greenhouse gas emissions by meeting strict energy efficiency specifications set by the government. In 2007 alone, Americans, with the help of the ENERGY STAR program, saved about $16 billion on their energy bills while reducing the greenhouse gas emissions equivalent to those of 27 million vehicles.
