As the demand for sustainable and energy-efficient heating and cooling solutions grows, many building developers and property managers are asking: Can heat pumps be used in apartment buildings? The answer is a resounding yes. With proper design and integration, heat pumps—particularly air to water heat pumps—offer a low-carbon, cost-effective alternative to traditional systems in both new and retrofit multi-residential buildings.
In this article, we’ll explore how heat pumps work in apartment settings, the benefits and challenges of implementation, and what you need to consider when planning installation in multi-unit dwellings.
Heat pumps transfer thermal energy rather than generate it. In the case of air to water heat pumps, heat is absorbed from the outside air and used to warm water, which is then circulated through radiators, underfloor heating, or fan coil units.
In apartment buildings, heat pumps can be deployed in two main configurations:
Centralized System – A shared heat pump supplies heating and/or hot water to all units.
Decentralized (Individual) System – Each apartment has its own dedicated unit.
Heat pumps consume less energy than gas boilers or electric resistance heating, reducing energy bills for residents and landlords alike.
Air to water heat pumps can cut CO₂ emissions by up to 60% compared to gas systems, helping developers meet green building codes and ESG targets.
Modern units are compact and can be installed on rooftops, balconies, or utility areas. For decentralized setups, indoor units can fit within a utility closet.
Many heat pumps offer integrated solutions for space heating, cooling, and domestic hot water (DHW), reducing the need for multiple systems.
Many countries offer government subsidies and rebates for heat pump installation in residential buildings, including apartment blocks.
| Configuration | Description | Pros | Cons |
|---|---|---|---|
| Centralized | One or more large heat pumps serve all units | Lower per-unit cost, easier to manage | Complex piping, less individual control |
| Individual | Each apartment has its own heat pump system | Full user control, easier billing | Higher upfront cost, more installation logistics |
In high-rise buildings, centralized systems are often favored, while low-rise or mid-rise developments may opt for decentralized units.
Well-insulated buildings maximize heat pump efficiency. Retrofit projects may require upgrades to windows, walls, and roofs.
Hydronic piping must be carefully designed to ensure balanced flow, especially in central systems. Zoning and pressure regulation are key.
Modern heat pumps are quiet, but correct placement (e.g., on rooftops or enclosed balconies) and vibration isolation are important in dense settings.
In buildings with high hot water usage (e.g., student housing), buffer tanks or thermal stores can ensure supply during peak times.
Smart thermostats allow residents to manage their own comfort

Retrofitting Existing Buildings: Space constraints and outdated piping can complicate installation.
Cold Climate Performance: In colder regions, consider hybrid systems with backup boilers or low-temperature optimized heat pumps.
Load Balancing: Proper load calculations are essential to avoid undersizing or oversizing.
Yes—heat pumps can absolutely be used in apartment buildings, whether through centralized systems or decentralized units. With rising energy prices and carbon regulations, they represent a future-proof investment that aligns with modern efficiency and sustainability goals.
If you’re developing, retrofitting, or managing a multi-unit residential property, working with experienced HVAC engineers will ensure optimal system design, installation, and long-term performance.
