- | A cogeneration unit next to the building produces electricity and heat with gas from the water purification process (Figure 4). The heat is exported to a district heat network for use in space heating and hot water. The cogeneration share of heat is estimated at 94 percent. The lines are very short, so losses are low. The biogas from purification has an PER factor of 1.1, but only within the biomass budget of 20 kWh/ | + | A cogeneration unit next to the building produces electricity and heat with gas from the water purification process (Figure 4).
