Heat pumps: Basics and planning guidelines for existing single-family homes and apartment buildings Further information and documents can be found at the Energy Action Group: https://aktionskreis-energie.de/event... Heat pumps are not only installed in new buildings, but are also particularly suitable for existing buildings. Right now, the desire to replace an existing oil or gas heating system is particularly great. Our speaker, Dipl.-Ing. (FH) Sven Kersten, has been working intensively with heat pumps for 15 years, first at EnergieAgentur.NRW and then for the NIBE Group. He is also a speaker for the Federal Association of Heat Pumps eV and an approved speaker according to VDI 4645. He gives us an overview of heat pump application options and explains: - Why is the presence of radiators no longer an exclusion criterion for the efficient operation of heat pumps? - Which heat pumps are suitable for which building? - What efficiencies can be achieved and what must be taken into account when designing them? - What funding programs are there and how comprehensive is the scope of funding? The special requirements for air-water heat pumps in terms of installation location and sound insulation and the combination of a heat pump with photovoltaics and electricity storage are also addressed. Theoretical principles from the university, practical experience from the planning of heat pump systems of all sizes in order to plan and operate both reliable and highly efficient heat pump systems, come from Prof. Werner Schenk. Basics and planning guidelines for single-family and multi-family homes in existing buildings: - Simple planning strategy with the 6-point plan - Determining the heat pump's heating output - Procedure for selecting the heat source - Hydraulics and determining the necessary flow temperature - Measures for radiators - Options for preparing domestic hot water in accordance with DVGW W 551 and - Hydraulics for high operational reliability and good performance figures - Examples with operating experience and measurement results
