Heat pump tenders
Heat pumps have become the default replacement for fossil heating in public buildings across Europe, and the tenders show it. Schools, hospitals, social housing landlords and municipal estates tender heat pump supply and installation, often as part of a wider refurbishment; district heating operators tender large heat pumps that draw on rivers, sewage or industrial waste heat; and public frameworks let multiple buyers call off heat pump work without a tender of their own.
Notices specify capacity, the heat source (air, ground or water), flow temperatures, refrigerant, noise limits and seasonal efficiency, and frequently ask for design, installation and several years of maintenance in one contract. The refrigerant is increasingly a scoring point, with natural refrigerants favoured under European F-gas rules. Larger district heating schemes are tendered in stages, with design and prequalification first.
