Aris hydronic home comfort system components
Piloting in Portland & Seattle Metros · Launching 2027

Comfort, re‑engineered

Heat, cool, fresh air, and limitless hot water—all from one high-performance, ultra-efficient hydronic system.

How it works

Aris heat pump harnessing and moving energy

Harness & move

A heat pump captures energy; hydronic loops shuttle it throughout your home.

Aris software orchestrating home thermal demand

Orchestrate

Predictive software balances zones, hot water demand, and grid-friendly load-shifting.

Aris hydronic comfort delivery

Deliver

Whisper-quiet comfort, lower bills, and real-time performance data.

The Aris System

Aris outdoor air-to-water heat pump

Heat pump

Our air-to-water heat pump is available in three sizes to fit every home. The monoblock design keeps refrigerants outdoors, reducing the risk of leaks by 99%.

Aris thermal storage tank

Thermal storage

Water tanks that operate as thermal batteries optimize efficiency and enable load-shifting.

Aris hydro control unit

Hydro control unit

The brain of the Aris system. This smart indoor module manages heating, cooling, and hot water flows with precision. It balances comfort and efficiency by orchestrating circulation, zone control, and domestic hot water.

Aris room fan coil

Fan coils

Fan coils deliver comfort directly into each room. They use water instead of refrigerant, providing quiet, efficient heating and cooling.

Hydronics 101

Circulating water instead of air or refrigerants, warming your home in winter and cooling it in summer with best-in-class efficiency.

Water is an efficient thermal carrier. Aris uses it to move comfort quietly through the home while keeping refrigerant outdoors and reducing the complexity of conventional HVAC.

Fresh air

Continuous fresh air, with balanced ventilation and energy recovery.

Aris designs fresh-air ventilation as part of your home’s mechanical system. Dedicated energy recovery ventilators supply bedrooms and living spaces and extract air from bathrooms and other appropriate rooms. Energy recovery reduces heat and moisture losses, while bathroom boost handles shower moisture. Equipment, airflow, and kitchen exhaust are designed for each project.

David & Leslie (Pilot Customers)
Aris is at a different level of system design and performance from anyone else we’ve worked with.
Josh Salinger, Founder & CEO, Birdsmouth Design-Build
At around 55°F outside, my building appears to self-heat. That's not a typo. It's a triumph of design.
