Application: Market environment.
The heat pump system for new multi-family houses.
- large demand for modern, sustainable and simultaneously affordable living space
- numerous legal framework conditions with regard to achieving CO2‑neutrality – not just for heat production
- large amount of stress for investors with regard to the procurement of high-quality residences in a sustainable design at low investment costs with simultaneously high legal requirements

Application: Object.
The heat pump system for new multi-family houses.
A multi-family house with 10 to 15 residential units.
For a multi-occupancy building of this kind, a centralised heat supply and a decentralised domestic hot water heating system are desirable. The number of residential units can be individually scaled by adapting the output size of the heat pumps or via a cascade. This results in an efficiency-optimised system application for a heat-pump central heating system operated via a single energy source.

Application: Requirement.
The heat pump system for new multi-family houses.
The requirement:
- future-oriented, highly efficient and sustainable heat production
- efficient heat-pump operation through decentralised electric domestic hot water heating
- residents' and/or property owners' demand for individuality, comfort and low operating costs

System
Expansion stage 1:
Electric wall‑mounted boiler.

System: Expansion stage 1.
Logamax E156 wall-mounted boiler
- compact design
- can be combined with other heat generators without any issues
- seven output sizes from 6 kW to 24 kW
- simple operation
- can be cascaded with up to six units
- pump, pressure gauge, pressure-relief valve and automatic air vent integrated
- suitable for screed drying

System: Expansion stage 1.
Electric wall‑mounted boiler.
System advantage:
The Logamax E156 wall‑mounted boiler supports the system perfectly as an additional heat source and supplies high flow temperatures of up to 85 °C. High redundancy: If the heat pump is not ready for operation, the Logamax E156 assumes responsibility for heat production.
As an addition to the heat pump, the electric wall‑mounted boiler is also ideal for screed drying. This makes it possible to avoid potential defects such as cracks or mould formation.

System advantage:
An increase in the insulation standard improves the tightness, ensuring that the air change-over over the building envelope is minimised. The air change-over is of equal importance to the building's structure and for its residents. Therefore, it is recommended to expand the basic system to include heat recovery ventilation, which guarantees the automatic air change-over and a comfortable indoor climate while maintaining a high level of efficiency.
