How heat pump water heaters improve efficiency in commercial buildings

Hot water plays a critical role in many commercial buildings, from restaurants and hotels to multifamily properties and offices. As businesses look for ways to improve efficiency and modernize building systems, heat pump water heaters are becoming an increasingly practical option.

For many commercial buildings, this technology can support long-term energy savings, improved performance, and reduced environmental impact.

In this post, we explore how heat pump water heaters can support more efficient commercial water heating and what businesses should consider when exploring this technology.

How heat pump water heaters work

Heat pump water heaters work differently than conventional commercial water heating systems. Instead of generating heat through electricity or burning fuel, they capture heat from the surrounding air and use it to warm water.

Because they rely on surrounding air to do much of the work, heat pump water heaters use significantly less electricity than standard electric water heaters, making them an efficient option for many commercial applications.

These systems perform best in spaces with sufficient room and airflow, such as mechanical rooms, basements, or utility areas commonly found in commercial buildings. Limited space or poor ventilation can impact performance.

Over time, using up to four times less electricity than a standard commercial water heater can contribute to improved efficiency while meeting the hot water demands of commercial buildings.

Key benefits of switching to a commercial heat pump water heater

Switching to a heat pump water heater offers several advantages for commercial buildings in Massachusetts.

• Improved energy efficiency: Heat pump water heaters use the surrounding air to heat water, which requires much less electricity than conventional electric water heating systems. By using less energy to meet hot water demands, commercial buildings can reduce overall energy use.
• Reduced operating expenses: Because they operate more efficiently, heat pump water heaters can help lower ongoing operational expenses compared to standard commercial water heaters, resulting in long-term meaningful savings. With typical lifespans ranging from 10 to 15 years, these efficiency gains can add up overtime and help offset upfront investment.
• Added building comfort benefits: Heat pump water heaters can slightly dehumidify the air in the space where they are installed, such as mechanical rooms or basements. They also tend to operate quietly, which can be beneficial in occupied commercial environments.
• Long-term asset value: Heat pump water heaters typically have longer lifespans than standard water heaters and can contribute to the overall value and performance of a commercial building, particularly for owners prioritizing efficiency upgrades and long-term planning.
• Lower environmental impact: Using less energy means heat pump water heaters produce fewer greenhouse gas emissions than traditional electric or fuel fired systems. Replacing older, less efficient water heating equipment with a heat pump water heater can support building decarbonization goals while improving energy performance.

Knowing if a heat pump water heater is right for your business

While heat pump water heaters offer many benefits, they may not be the best fit for every commercial building or installation location. Because they pull heat from the surrounding air, placement and building conditions play an important role in performance.

Heat pump water heaters generally work best in commercial spaces with adequate room, airflow, and ambient temperatures, such as mechanical rooms, basements, or dedicated utility areas. Installing a system in tightly enclosed or highly conditioned spaces, especially those occupied by customers or employees, may not be ideal, as the unit can draw in heat from the surrounding area.

Evaluating factors such as building layout, available space, climate, and hot water demand can help determine whether a heat pump water heater is the right solution, or if another high efficiency option may be a better fit.

For businesses considering an upgrade, a no-cost Small Business Energy Assessment or Technical Assistance for Large Commercial & Industrial customers can help identify appropriate water heating solutions and available incentives based on the needs of the building.

Heat pump water heater rebates and incentives

If a heat pump water heater is the right fit for your business, rebates and incentives offered by the Sponsors of Mass Save® can make upgrading more accessible. Eligible businesses that replace qualifying water heating equipment may qualify for financial incentives to support the upgrade.

Businesses can participate by working with a contractor and a participating distributor. The Sponsors of Mass Save® work with a network of distributors who can support you and your contractor in identifying the appropriate high efficiency water heating equipment for your building. Participating distributors help ensure eligible equipment is selected and that available incentives are incorporated as part of the installation process.

For qualifying equipment purchased through a participating distributor, incentives from the Sponsors of Mass Save® are typically applied at the point of purchase and reflected on the invoice. Your contractor and distributor work together to confirm eligibility and ensure the appropriate incentive is applied as part of the transaction.

Pipe, tank, and valve insulation

In addition to incentives for qualifying water heating equipment, the Sponsors of Mass Save® also offer incentives for pipe insulation upgrades that can further improve system performance. Insulating hot water and steam pipes helps reduce heat loss, maintain water temperature, and support efficiency in commercial buildings.

For businesses upgrading water heating systems, combining equipment upgrades with pipe insulation can be a cost-effective way to maximize energy savings. Incentive amounts for eligible pipe insulation projects vary based on project details.

Purchasing a heat pump water heater

Heat pump water heaters can be a practical option for Massachusetts businesses looking to improve water heating efficiency while supporting long-term operational and environmental goals. When planning an upgrade, businesses should consider how heat pump water heaters fit within broader building efficiency or electrification strategies, evaluate available space and hot water needs, and explore rebates and incentives offered through the Sponsors of Mass Save®.

Working with a qualified contractor and participating distributor can help ensure the right system is selected and installed properly, while also supporting eligibility for available incentives. With thoughtful planning and the right support, heat pump water heaters can provide an efficient, reliable water heating solution for commercial buildings for years to come.
