Buildings account for around 40 percent of global energy consumption. The lion’s share of this goes toward heating and hot water for residential buildings. Efficient Bosch heating technologies reduce energy needs and thus also CO2 emissions, especially when they draw on renewable sources of energy such as solar or ambient heat.

Solar heat: solar energy uses the sun’s endless supply of energy to generate heat and hot water. To this end, the carrier fluid contained in the solar modules absorbs solar heat and transfers it to a hot water tank via a heat exchanger. Even in countries with less sunshine, such as Germany, drinking water can be heated almost entirely with solar power. To this end, an energy-plus house requires some six square meters of collectors, which prevent up to 1,000 kg CO2 each year. And the bigger the collector surface, the less dependent a building’s residents are on fossil fuels.

Ambient heat: Heat pumps work like a reverse refrigerator of sorts: they draw heat from the ground, the ground water, or ambient air and transfer it to the heating cycle. To do this, the pumps operate with small amounts of electricity or gas. The most efficient models – among them the Buderus Logatherm WPL 8 AR air heat pump – require 25 percent primary energy to provide 100 percent of the required heat. The efficiency of a heat pump can be determined through the seasonal performance factor and the coefficient of performance value. The higher the value, the more energy-efficient the heat pumps.

In energy-plus houses, regenerative heating systems are already contributing to generating more energy than the residents need.
