What Purmo Group does
Purmo Group is a Finland-based provider of indoor climate comfort solutions, headquartered in Helsinki and listed on the Helsinki Stock Exchange (ticker PURMO). The company serves residential and commercial building markets across Europe, with a product portfolio anchored on radiators and increasingly extended into air-to-water heat pumps and integrated ventilation systems for building decarbonization. Underlying technology is hardware-centric: thermal heat transfer systems, heat pump refrigerant cycles, and building ventilation, marketed and sold via B2B enterprise field sales and direct sales channels into installer, specifier, and project-based customers.
The business model is primarily hardware sales of heating and cooling systems, with revenue tied to unit shipments of radiators, heat pumps, and ventilation products to commercial and residential building projects. Purmo's owned by Apollo and Rettig following a $658 million acquisition, with Rettig's April 2024 funding round reinforcing that ownership. Growth is executed through strategic M&A: in October 2024 Purmo acquired Dublin-based Unitherm Heating Systems Ltd for an undisclosed amount, adding 65 employees, EUR 28.2 million in 2023 net sales, and an Ireland/UK regional headquarters. Geographic footprint covers Finland, Ireland, and the UK, with horizontal segmentation across residential and commercial use cases and no public pricing transparency beyond quote-based enterprise sales.
