Overcoming the Retrofit Wall High-Temperature Heat Pumps Clear the Path for Commercial Building Electrification
United States, 29th Jul 2025 – One of the biggest challenges in commercial building decarbonization is the high cost of replacing fossil fuel heating systems. Retrofitting old buildings with electric heating often requires major upgrades—new piping, coils, and controls, which many building owners can’t afford.
A new type of high-temperature heat pump, developed in the U.S., could change that. This technology provides hot water at temperatures up to 170°F in outdoor conditions of 30°F (160°F at 17°F), making it suitable for many existing systems without requiring major modifications. In some cases, retrofit costs can be reduced by up to 80% compared to traditional electric systems.
Commercial buildings use 18% of U.S. energy, with about 32% of that for space heating, according to data from the U.S. Department of Energy and the Energy Information Administration.
With new electrification rules and incentives from federal and state governments, building owners are under pressure to act. But many current solutions either cost too much or create more demand on the electric grid. High-temperature heat pumps offer a possible answer by fitting into existing systems and using less energy than electric resistance heating.
Despite growing residential adoption, commercial heat pump use has lagged. According to the U.S. Energy Information Administration (EIA), approximately 32% of commercial energy use is for space heating, often relying on gas or oil systems. Transitioning to electric alternatives typically requires extensive and expensive upgrades: new piping, coils, controls, and often entire distribution systems.
Nyle Water Heating Systems, based in Bangor, Maine, is a U.S. manufacturer specializing in high-efficiency, heat pump-based water and space heating systems. With decades of engineering experience and a focus on solving real-world retrofit challenges, Nyle designs equipment that helps commercial buildings reduce emissions without costly overhauls. The company is also Build America Buy America Act (BABA) compliant, with domestic manufacturing that aligns with federal infrastructure investment priorities.
Its latest development, Alectro, is an air source, high-temperature heat pump built to lower the cost and complexity of electrifying existing commercial heating systems. By meeting the performance demands of older buildings without requiring system replacements, Alectro addresses one of the most persistent obstacles in commercial building decarbonization.

“Electrifying commercial buildings shouldn’t mean tearing them apart,” said Chris Ebener, President of Nyle Water Heating Systems. “With Alectro, we’ve engineered a solution that works with existing building infrastructure, unlocking retrofit opportunities that were previously out of reach.”
Unlike conventional heat pumps that operate at lower temperatures, the Alectro delivers high-temperature output, allowing it to integrate seamlessly with legacy systems. This reduces capital costs, shortens installation timelines, and eases the transition for facility managers, engineers, and developers alike.
Federal, state, and local mandates are accelerating the push for electrification, but progress has been hampered by budget constraints and technical complexity. Traditional electric heating options often strain local grids or carry long-term operational costs that make them less appealing for large-scale deployment.
The Alectro will be launched on August 1 and will be showcased at the AHR Expo 2026 (Feb. 2–4), one of the industry’s largest HVACR events, where it is expected to draw attention from engineers, policy makers, and commercial property leaders seeking viable retrofit solutions.
