Heating system manufacturer Vaillant and building technology specialist Alois Müller have developed a modular central heating system for large residential complexes.
"Thanks to modular heating centers based on heat pumps, large residential complexes and commercial properties can now also be supplied with hot water and heating energy from renewable sources," is the advertising promise from Vaillant and Alois Müller. The two companies have developed a system solution for residential complexes.
The solution is called the "Energy Unit", which should make it possible to renovate large residential complexes much faster than before in terms of energy efficiency. This is because the modular heating center is connected as a separate, external unit, which significantly speeds up installation. "The new heating center is completely preconfigured by us in advance. The days when a lack of space in the boiler room slowed down the energy transition are finally over," says Andreas Müller, Managing Director of the Alois Müller Group.
The entire system technology, the buffer cylinder and the control of the heating circuits are already combined in the unit ready for connection and are installed on site by Vaillant employees. Heat pumps from Vaillant are used for the Energy Unit. Depending on the heat load and the number of heat pumps used, the heat pump block has an output of 20, 30, 40 or even 65 kW. The new system solution from Vaillant and Alois Müller is not only suitable for energy-efficient refurbishment of existing buildings, but also for new construction projects in multi-storey residential or commercial buildings.
Thanks to a cascade connection, even large residential properties with up to 30 residential units and a heat load of up to 65 kW can be supplied via the new Energy Unit heat pump, according to the two companies. This can be operated monoenergetically or as a gas hybrid variant.
The medium-sized energy and building technology specialist Alois Müller, based in Ungerhausen, Bavaria, employs almost 1,000 people at 14 branches across Germany. Among other things, the company is known for its Green Factory in Ungerhausen (we reported). The 18,000 square metre production and office building is not only the company headquarters, but is also an energy self-sufficient, CO2-neutral factory and a prime example of how environmentally and energy-optimized production can be achieved in industry. In future, the energy units will also be prefabricated in series in the Green Factory.
