Enerin to pursue heat pump certification for US market
Photo call for the finalists at the Empire Technology Prize award ceremony held in New York in September 2025.
Enerin COO, Trond-Atle Asphjell, attended the Empire Technology Prize award ceremony in New York on 19 September, 2025, where he shared the company’s vision for accelerating the adoption of heat pumps for central heating solutions in New York.
Trond-Atle spoke about how Enerin’s technology overcomes the key barriers to heat pump adoption in New York City, why we were selected for the prize, and what’s next on our journey to bring sustainable, high-impact heating solutions to the New York market.
Enerin was selected as one of the final seven companies to qualify for the ETP prize in July 2024. The company competed in the category to supply decarbonised hot water and steam solutions for centrally heated tall buildings and skyscrapers in New York State. The award was based on the finalists achieving specific milestones with prize money attached. Enerin is pleased to announce that:
We advanced in the ETP competition by securing a Letter of Intent from an official demonstration partner for a potential project in New York.
Our engineers successfully designed a prototype heat pump to meet the specifications of the Empire Technology Prize.
We have commenced the UL certification process for our HoegTemp high-temperature heat pump in the United States.
We will continue to pursue our entry into the US market, including the UL listing and certification of our heat pump which should be complete by the end of the second quarter, 2026. We are currently co-operating with US energy installation and distribution partners, as well as interested end-users.
With the support of the Royal Norwegian Consulate General in New York and Innovation Norway in New York, Enerin is examining the regulatory frameworks concerning our entry and the establishment of our company in North America.
Unlike conventional heat pumps that rely on a phase change of the working medium—where a fixed relationship exists between temperature and pressure—Enerin’s Stirling machines can effortlessly handle temperature variations on both the hot and cold sides.
Enerin’s high-temperature heat pumps are highly suitable for a 1:1 boiler-swap working with existing heating and cooling infrastructure in New York State with minimal retrofitting and disruption to existing residents.
The flexibility of the heat pumps to operate across a wide temperature range using multiple heat sources and excess renewables delivers cheaper integration with lower operating costs.
Our Stirling heat pumps operate in a dry state using helium as the working fluid. Helium is the safest, non-toxic, environmentally-friendly refrigerant with zero Ozone Depletion Potential and zero Global Warming Potential. It poses no risk of fire, explosion, or evacuation risks for dense urban areas.
Enerin congratulates Miller Proctor Nickolas, Inc., Inc (MPN Boilers) as the winner of the ETP prize.
New York State Energy Research and Development Authority President and CEO, Doreen M. Harris, congratulates the MPN team.
