Aira is a Swedish company that designs its own R290 heat pump, builds it in Wroclaw, Poland, and sells and installs it directly to UK homes. It offers 6, 8 and 12 kW outdoor units, publishes real-world performance data from UK installs, and bundles a 15-year guarantee into a paid all-inclusive plan. As with Octopus Cosy, you cannot buy an Aira unit through an independent installer. We list the 8 kW: Aira does not publish the weight or sound power of the single-phase 12 kW.
