The Division of Vitality goals to scale back limitations to expertise adoption by offering personalized, complete steerage for sizing, choice, and set up

The U.S. Division of Vitality (DOE) has launched a brand new web-based software that provides complete details about how you can measurement, choose, and set up electrical warmth pump water heaters (HPWHs) — a key expertise for advancing the Biden–Harris Administration’s nationwide clear vitality targets. HPWHs might be two to 4 occasions extra environment friendly than normal models, which interprets to vitality financial savings and decreased carbon emissions. These advantages are maximized when installers comply with greatest practices and select the most effective mannequin and measurement for the house. The HPWH Set up Device makes this simpler than ever, offering personalized steerage for installers, gross sales associates, and householders to assist overcome limitations to HPWH adoption.

“The Heat Pump Water Heater Installation Tool will make energy-efficient retrofits easier than ever, enabling homeowners to take advantage of Inflation Reduction Act incentives,” stated James Carlisle, appearing director of the DOE Constructing Applied sciences Workplace.

Pacific Northwest Nationwide Laboratory (PNNL) created the HPWH Set up Device with funding from the Constructing Applied sciences Workplace’s Residential Buildings Integration program. PNNL researchers consulted with a number of organizations, together with different nationwide laboratories, regional energy-efficiency organizations, state vitality applications, and installers in California, Oregon, and Washington.

A New, Environment friendly Means of Heating Water

A HPWH resembles a conventional water heater, however somewhat than utilizing a gas-fired burner or electrical ingredient to heat the water within the tank, the HPWH extracts warmth from the encompassing air. HPWH models are identified for his or her effectivity, which interprets to vitality financial savings and decreased carbon emissions.

However consultants imagine lack of public familiarity with the expertise’s advantages, availability, and set up necessities has hindered adoption.

“Not only does the installation tool help demystify these water heaters, but it provides contractors and service technicians with confidence in installing the technology, which consumers will notice. I see that as a big benefit in getting more heat pump water heaters into homes,” stated PNNL’s Alek Parsons, an engineer who helped develop the software.

Navigating Buy & Set up

“Heat pump water heaters, like traditional water heaters, last for about 15 years, but there are differences in how they are installed and operated,” stated PNNL’s Josh Butzbaugh, who led growth of the software. For instance, he famous that warmth pump water heaters require a specific amount of airflow to function successfully, so the placement of the water heater must be evaluated.

Sizing can also be a vital consideration. An appropriately sized HPWH will meet the recent water wants of a family. Conversely, an undersized heater may, beneath sure circumstances, lead to lukewarm water and a cold reception by the home-owner.

The set up software additionally helps decide whether or not a house’s electrical panel must be up to date—a standard scenario when changing a fossil fuel-fired water heater with a HPWH—or if a HPWH that plugs into a typical 120-volt electrical outlet is likely to be a viable possibility.

Utilizing the Device

The choice software was designed as a “one-stop shop” for individuals inquisitive about HPWHs to get assistance on choosing and putting in models in present properties. The software delivers personalized suggestions together with common details about HPWHs, how they function, and the advantages for each householders and installers.

To begin, customers comply with prompts to enter particular details about their residence, together with the zip code—to align suggestions with the suitable local weather zone—and the variety of bedrooms and bogs. The person then gives particulars in regards to the HPWH’s potential location, corresponding to airflow, skill to empty condensation, and house constraints. Customers additionally present info on sound issues; the proximity of a heating, air flow, and air-con (HVAC) thermostat; and the presence of home equipment corresponding to soaker tubs or spas, which could have an effect on the quantity of scorching water wanted at one time.

Most customers will spend lower than 10 minutes finishing the shape. The software then shortly converts the submitted info into personalized suggestions for HPWH sizing, set up, and potential residence alterations which may improve efficiency. The software additionally presents set up greatest practices and details about out there tax credit and incentives.

“The Inflation Reduction Act provides incentives for heat pump water heaters beyond existing tax credits,” Butzbaugh stated. “As a result, it’s likely there will be increased consumer interest in this equipment. The installation tool puts useful information in the hands of homeowners and installers at an opportune time.”

DOE is assured the set up software will turn into an important a part of coaching applications for installers and for employees in product name facilities, retail gross sales, and customer support who discipline questions from potential water heater prospects, in addition to in workforce coaching applications.
