Edged Partner ThermalWorks Introduces Breakthrough Heat Recovery Technology, Allowing Data Centers to Repurpose 100% of the Waste Heat from IT
New feature eliminates the cost barrier to utilizing data center waste heat for local industry and communities.
ThermalWorks announces that its 1 MW (pictured here) and 2 MW Waterless Chiller Plants will now be available with integrated heat recovery.
NEW YORK, NY – (March 17, 2025) –ThermalWorks, a subsidiary of Endeavour that develops ultra-efficient, AI-ready waterless cooling systems for the data center industry, today announced the launch of advanced heat recovery technology as a standard option for its 1 MW and 2 MW waterless chiller plants. This technology allows data center operators to harness low-cost, high-grade heat (140ºF or 60°C)—transforming waste heat into a valuable, carbon-neutral energy resource. By making heat recovery a standard option on its integrated chiller plants, ThermalWorks is eliminating the capital cost barrier that has limited mainstream adoption.
“Data centers generate significant waste heat, but recovery systems have traditionally been treated as a secondary add-on, which resulted in high expenses and relatively low temperatures,” says ThermalWorks CEO John Costakis. “By fully integrating heat recovery in our next-generation modular chiller plants, we were able to make it more efficient and dramatically increase the temperature of the exported heat. This makes it more valuable for communities and nearby industry. The most exciting thing is that we were able to design that option as a low-cost plug-in cartridge, so waste heat utilization will make financial sense in a lot more places.”
The ThermalWorks cooling system already achieves industry-leading peak and average Power Usage Effectiveness (PUE) under any operating conditions. This new technology makes it also one of the most efficient heating systems available. For every 1 kW of power, the heat recovery system can generate more than 40 kW of heat (just 25kW of additional load per MW of high-quality exported heat). The low-cost waste heat is carbon neutral and can displace heat from fuel-burning boilers, which directly reduces climate impacts.
“With AI and high-density computing driving energy demands higher than ever, we need innovative solutions that rethink efficiency at every level,” said Endeavour founder Jakob Carnemark. “The ThermalWorks team has led the industry by eliminating our data centers’ water consumption—and now they’re pushing further ahead with advanced energy recovery. By capturing and repurposing heat, they’re helping turn waste energy into a sustainable asset for communities. This enables data centers to become key contributors to local energy ecosystems.”
With the next-gen ThermalWorks system, a 100 MW AI data center could provide enough heat for a large industrial campus, 80+ large warehouses or more than 30,000 U.S. homes[1]—offering a tangible, sustainable benefit to local communities.
ThermalWorks waterless cooling systems are manufactured globally at gigawatt-scale. The new heat recovery feature has been added to both the C1000 (1 MW) and C2000 (2 MW) chiller plants.

What’s a Rich Text element?
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
Static and dynamic content editing
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
How to customize formatting for each rich text
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
