roducts entered in this prestigious program are judged by a preeminent panel of independent industrial designers, independent engineers and members of the trade media to honor outstanding design and engineering in cutting edge consumer electronics products across 28 product categories. The new lineup, which will be available in early 2017, offers nine models for high-efficiency domestic hot water in residential or commercial applications, adding new features for easy installation, operation and maintenance. “We are thrilled to receive this recognition,” said Vitor Gregorio, regional president, Bosch Thermotechnology Corp.

“It’s a testament to the innovation, engineering and design that Bosch brings to the entire HVAC category.” We’re excited to bring this lineup, and the comfort control it will provide, to people in their homes and businesses across North America.” The Greentherm 9000 Series models feature sleek, rounded corners on the metal cabinet, making these water heaters as beautiful as they are economical. The Greentherm 9000 Series models are highly energy-efficient, particularly the 9900i SER model, which features integrated Wi-Fi controls. Indoor units also feature top-mounted water connections allow for easier, faster replacement of tank-type water heaters. The prestigious CES Innovation Awards are sponsored by the Consumer Technology Association (CTA)TM, the producer of CES 2017, the global gathering place for all who thrive on the business of consumer technologies, and have been recognizing achievements in product design and engineering since 1976. These new products will be displayed at CES 2017, which runs January 5-8, 2017, in Las Vegas, Nevada.

Entries are evaluated on their engineering, aesthetic and design qualities, intended use/function and user value, unique/novel features present and how the design and innovation of the product directly compares to other products in the marketplace. Products chosen as CES Innovation Honorees reflect innovative design and engineering in some of the most cutting edge tech products and services coming to market. CES 2017 Innovation Honoree products are featured on CES.tech/Innovation, which lists product categories, as well as each product name, manufacturer information, description, photo and URL.

The CES Innovation Awards are based upon descriptive materials submitted to the judges. CTA did not verify the accuracy of any submission or of any claims made and did not test the item to which the award was given.

Much has already been said about the safety improvements homeowners and business owners can anticipate by switching from traditional water heaters to tankless models.

Usually the discussions have revolved around the half a million scald or burn incidents happening every year, many caused by overheated tap water from an old or uncalibrated water heater. According to the Burn Foundation, more than one-sixth of all childhood hospitalizations from scalds happen because of hot tap water.

That said, another threat endangers those who use both residential and commercial tank heaters: Legionnaires’ disease. What causes Legionnaires’ bacteria to grow and how can traditional tank heaters put your home or business at risk?

“Legionella grow in still warm water.”

What is Legionnaire’s disease?

Legionnaires’ disease is actually a body of diseases – more than 43 according to the U.S. Occupational Safety and Health Administration – all caused by the same bacteria called Legionella. This pathogen grows in still warm water. If inhaled through water vapor, these bacteria could cause fever, pneumonia, comas and even death.

So, how does a standard hot water tank turn into a Petri dish for Legionella? Unfortunately, a few different ways.

How can hot water tanks produce Legionella?

Fiddling with hot water tank temperatures for energy efficiency gains could set off a chain reaction producing Legionella. Many energy experts, including the U.S. Department of Energy, recommend setting hot water tanks to 120 degrees Fahrenheit to shave a few bucks off a home gas bill. Unfortunately, Legionella can survive that temperature and prosper. OSHA recommends keeping tanks at 140 degrees, which effectively neutralizes Legionella-infected water, but hot water at that temperature could easily scald children or seniors with sensitive skin. Either way, water tank owners lose.

“Sediment collecting in water tank can encourage Legionella growth.”

Sediment collecting at the bottom of a dilapidated water tank can also encourage Legionella growth. If tank owners neglect to flush their systems at least once a year to rid systems of calcium carbonate buildup – common in areas with high water hardness – and other debris, Legionella could develop with time.

Legionella also breeds in pipes where stagnant hot water cools below that 120-degree mark. As hot water trapped between a water tank to a faucet or tap cools, it becomes more and more susceptible to infection.

Fight disease with tankless water heaters for your home

Tankless water heaters provide a number of solutions for these problems. First and foremost, automated technology controls hot water temperatures right at the source, so it’s always the perfect temperature: warm enough to prevent waterborne disease, cool enough to avoid scalds and energy-efficient enough to keep monthly bills low.

Point-of-use tankless water heaters not only forego the large cylindrical basin where Legionella can grow, but also reduce the piping needed to deliver water from a utility to the faucet, thus eliminating another threat. Water moves directly from the public system, into the home and right to the tap where it’s heated on demand

.If your hot water heater isn’t working for you, it’s working against you. Choose tankless models to prevent the spread of Legionella, protect your family from overheated water and save money on your energy bill.

• For use with Bosch Greentherm Tankless Water Heaters
• Clean, efficient alternative to conventional furnaces
• When used with tankless water heater it produces both efficient heat and virtually endless hot water
• Simple setup requires a single gas line and venting system for the tankless water heater
• Single burner system on the tankless water heater promotes increased service life, requires lower maintenance than traditional furnace and hot water system

Bosch Thermotechnology Corp. launches its new Bosch Hydronic Air Handlers offering a more efficient, compact and advanced home heating system. When paired with the Bosch Greentherm Gas Condensing Tankless Water Heater, homeowners can benefit from a more efficient heating system with a virtually endless supply of domestic hot water.

The new Bosch Hydronic Air Handler can replace furnaces with a ducted system, eliminating the need for a gas pipe, venting and fresh air intake required for furnaces.

The entire system is easily managed by an integrated control board that connects to the home’s thermostat. When the thermostat calls for heat, the air handler immediately activates the integrated pump, turning on the fan 30 seconds later, allowing the heat exchanger to preheat to deliver comfortable warm air from start-up. After the thermostat is satisfied, the blower runs an additional 30 seconds to deliver conditioned air. The Bosch Hydronic Air Handler has an integrated pump timer that turns on the water circulator for 2 minutes every six hours to help prevent bacteria growth in the hot water system.

The Bosch air handler may be configured to work with A/C systems, providing a complete heating, cooling and hot water solution. When the thermostat calls for cooling, the control board activates only the blower.

The new hydronic air handler connects seamlessly with tankless water heaters, transferring the unit’s highly efficient hot water through a hydronic heating coil. As the hot water circulates through the pipe, warm air is sent through the residential duct system. The cool water in the hydronic coil then recirculates to the tankless unit to be reheated.  Two models – AHU 50 and AHU 70 – can be sized with most cfm and BTU output ratings to suit most typical size homes.

Combining both the Bosch Hydronic Air Handler and an ENERGY STAR 95% EF-rated Greentherm Tankless Water Heater results in an ultra-efficient heating and domestic hot water system. Plus, the combined system can provide home heating and hot water simultaneously so homeowners don’t sacrifice comfort. The product carries a limited five year parts and one-year limited labor warranty (see full warranty details at www.boschheatingandcooling.com).
