Aira’s New Domestic R290 Heat Pump Will Be Sold Directly to Consumers Via ‘All-Inclusive’ Monthly Payment Plan

The Swedish home energy company’s heat pump comes in three sizes and is available in Germany, Italy and the U.K.

Aira, a Swedish home energy company, has launched a new propane (R290)-based domestic air-to-water heat pump for the European market that will be sold directly to consumers through a monthly payment plan with zero upfront costs.

Aira is a portfolio company of Swedish climate venture capital firm Vargas and began operations in June 2023, with its first heat pumps supplied by German OEM Vaillant.

The specifics: The heat pump can produce water temperatures up to 70°C (158°F) for space heating (via radiators or underfloor piping) and domestic hot water. The system includes an outdoor unit, hot water tank, buffer tank, thermostat and mobile app.

  • Aira’s R290 heat pump comes in three sizes: 6kW, 8kW and 12kW (1.7TR, 2.3TR and 3.4TR). It is paired with either a 100l or 250l (26.4gal or 66gal) hot water tank. The buffer tanks – 40l (10.6gal) or 100l – help improve reliability and durability by “minimizing the system’s stop and restart sequences during low-demand months,” says Aira.
  • At an output temperature of 35°C (95°F), the system has a seasonal COP of 4.7 and an A+++ efficiency rating. The Aira Heat Pump has an operating range of −25 to 45°C (−13 to 113°F).
  • With the addition of fan coils, the system can also provide cooling, covering capacities of 8–13kW (2.3–3.7TR).

Payment plans and subsidies: The Aira Heat Pump is currently available in Germany, Italy and the U.K., and payment plans vary in length from one year to between 10 and 15 years, according to Fortune. Those on the one-year plan will not be charged interest, while those on the 10-to-15-year plans will.

  • Payment plans include all costs, including a home energy estimate, installation and removal of old heating equipment. Aira estimates its heat pump costs in the U.K. will be between £3,000−£5,000 ($3,819−$6,365/€3,504−€5,840) for a 1−2 bedroom home.
  • In what it calls an “industry first,” the company, depending on the customer’s location, also provides a 10- or 15-year “Comfort Guarantee,” which covers the product, its installation and its performance.
  • Aira customers can benefit from government subsidies like the U.K.’s Boiler Upgrade Scheme and the Federal Funding for Efficient Buildings in Germany.

A smart heat pump: The Aira Heat Pump is connected to the internet, with users able to control the temperature via app. In addition, the Aira app shows an estimate of monthly cost savings and emissions reductions as compared to an oil or gas boiler.

  • According to Aira, the system “intuitively learns” the unique needs of each home to adjust heating and hot water production based on daily routines.
  • The system is connected to local weather reports and automatically adjusts itself based on the forecast.

What it means for NatRefs: Aira’s goal is to install 5 million heat pumps in the next 10 years, which dovetails with the EU’s aims to have 30 million or more heat pumps installed by 2030 compared to 2020 under its REPowerEU plan. If Aira can meet its goals, the company could help ensure that propane spearheads the EU’s heat pump push.

  • Aira has a sizable war chest, having recently raised €145 million ($157 million) in funding, pushing its total funding (including government grants) to €195 million ($212 million). This includes a €15 million ($16 million) grant from Poland to support the development of Aira’s manufacturing facility in Wrocław.
  • By opting for propane, Aira has ensured its product is impervious to the region’s recently revised f-gas regulations and possible PFAS restrictions.

The CEO’s quote: “The launch of our new heat pump marks a key milestone in Aira’s journey to serve 5 million customers across Europe over the next decade,” said CEO Martin Lewerth. “Through this, we are helping more households unlock significant savings and reduce carbon emissions, all whilst adding value to their home with a state-of-the-art heat pump.”
