About the company
Bosch Home Comfort makes heating, cooling and hot-water equipment for homes, commercial buildings and industrial users. Its portfolio combines electric heat pumps with gas-fired boilers and hybrid systems, giving customers different ways to control building temperatures and supply hot water. The business sells equipment through its brands' sales networks, with products adapted to regional building needs and energy requirements. Its inverter-driven heat pumps adjust compressor output to match demand rather than running constantly at full power. The Bosch business unit was formed through the merger of Bosch and Buderus heating activities in 2004 and is headquartered in Wetzlar, Germany.
