Germany – Heating, ventilation and air-conditioning installation work – Los 403 Erneuerung Wärmeerzeugung / Heizzentrale - Ensemble Goethe-Wohnhaus: Denkmalgerechte Instandsetzung

The tender involves the renewal of a central heat generation plant including the dismantling of the existing plant. A 2-gas boiler system as a condensing boiler cascade, H2-ready (hydrogen-capable) with system separation and energy storage charging, including renewal of the exhaust system, is planned. The required total capacity is estimated at approximately 400 kW. The outdoor temperature-controlled modulating heat generator plant is to be operated in a future-proof manner with a system spread of 60/45 °C. The existing old 2-boiler system (2 parallel-connected identical sectional cast iron boilers with atmospheric burner and with return flow lift) from the year of construction 1990 will be completely dismantled including the exhaust system up to above the roof.
