The future of home heating, cooling, and hot water. 

Aris Wins $1 Million Department of Energy Prize

On Sept 19, 2024, the Department of Energy announced Aris Hydronics as the winner of the Equitable and Affordable Solutions to Electrification (EAS-E) Home Electrification Prize for its ARIS Home Comfort System for single and multi-family buildings. 



Modular, affordable, adaptable. 

ARIS offers the ultimate combined drop-in HVAC and Hot Water system. 

Our technology is fully integrated, mico-zonable, and suitable for any building type in all climate zones, including retrofits and new builds. 

An Entirely New Approach

ARIS™ offers home owners and renters security and peace of mind by providing precise control over their home comfort, through our one-of-a-kind technology and "Thermal as a Service" approach that bundles system design, sales, installation, and comprehensive post-sales data and support.

45% - 70% Energy Savings

Legacy HVAC systems are no match for ARIS, with a seasonal coefficient of performance (SCOP) five times better than gas heating and hot water appliances and two times better than legacy AC systems. 

The ARIS Home Comfort System keeps your home comfortable during blazing hot summers and chilly cold winters while offering superior performance and energy savings.

Patent-Pending Technology

After years of developing and testing, ARIS has created the world's first modular combi-heat pump system designed exclusively for multi-family buildings

Our one-of-a-kind solution is an advanced integrated, modular system that combines the most efficient heat pump technologies with low cost thermal energy storage, and cutting-edge hydronic HVAC components and controls. 

No Refrigerants in Your Home

Standard AC and split heat pump systems circulate toxic refrigerants with high global warming potential(GWP) inside homes. 

By harnessing the power of water, ARIS provides superior heating and cooling while keeping refrigerants safely outdoors where they belong, and eliminating the need for bulky ductwork and refrigerant line sets.

Field Tested.

It is one thing to make bold claims, and it is another to put prove it. The ARIS Hydronics team has been field testing our technology for years, with homes around the US currently using our system.
