What are the key priorities for healthcare institutions when choosing a new heating system? A hospital has a high and continuous energy demand, while comfort, reliability, and climate control are critical for both patients and medical staff. At the same time, regulations regarding CO₂ reduction and energy efficiency are becoming increasingly strict. When selecting a new heating system, more and more hospitals are looking toward high-capacity heat pumps. Modern air-to-water heat pumps can not only provide efficient heating but also cooling simultaneously. This makes a heat pump particularly suitable for complex commercial buildings such as hospitals. In this article, we discuss the primary points of consideration for hospitals, consultants, and installers when choosing a new heating system.
Specific Heat Demand in Hospitals
Hospitals differ significantly from other commercial buildings, and so does their heat demand. Hospitals operate 24/7 with continuous occupancy. There are strict requirements for the indoor climate, a constant consumption of domestic hot water, and a simultaneous demand for heating and cooling. Departments such as operating theaters, intensive care units, laboratories, and imaging rooms generate a lot of internal heat from equipment and lighting. These areas require cooling, while ward units and meeting rooms require heating. A flexible energy system capable of delivering both functions aligns perfectly with the energy profile of hospitals and healthcare institutions.
The Heat Pump as Part of a Sustainable Energy System
High-capacity heat pumps are increasingly being implemented in hospitals—either as a fully electric energy supply or as part of a hybrid configuration. Air-to-water heat pumps are particularly interesting in hybrid systems because they can be integrated relatively easily into existing setups with central heating boilers and domestic hot water systems. The heat pump handles the bulk of the thermal load, while the boilers provide support during peak loads or extreme winter periods.
Integrating a heat pump into a hospital's existing heating system offers the following benefits:
- Significant reduction in gas consumption: Up to 75%.
- Lower CO₂ emissions: Especially when using propane (R290) heat pumps.
- Simultaneous heating and cooling: Via 4-pipe systems.
- Improved Energy Performance Certificate (EPC): Enhancing the building's energy label.
- Integration: Seamless connection with existing renewable energy sources.
By installing multiple heat pumps in a cascade configuration, a system can be built with very high capacities and sufficient redundancy, ensuring operational reliability.
Simultaneous Heating and Cooling
In hospitals, it is common for certain departments to require heat while other areas need cooling. Modern air-to-water heat pumps can respond effectively to this. In addition to 2-pipe heat pumps, there are 4-pipe heat pumps consisting of two separate circuits. One circuit can provide heating while the other simultaneously provides cooling. An added advantage is that the heat extracted from cooled spaces can be reused for heating or domestic hot water production. This significantly increases the overall efficiency of the system.
For hospitals, this form of energy recovery can contribute substantially to energy savings.
Reliability, Redundancy, and Operational Security
For hospitals, operational security is an absolute prerequisite. Equipment failure must never pose a risk to the continuity of care. Therefore, heating systems for healthcare facilities are often designed with cascade arrangements. In this setup, multiple heating units operate side-by-side. If one unit fails due to a malfunction, the others take over, guaranteeing reliability. In such cases, a central heating boiler can also serve as a backup for the heat pump.
Integration with Building Installations
A new heating system must integrate seamlessly with existing technical installations. Modern heat pumps can be easily connected to current systems. Integration with the Building Management System (BMS) is essential, allowing energy consumption to be monitored continuously and optimized based on demand and occupancy. Optimal efficiency is often achieved through the synergy of various components, such as:
- Air handling units (AHUs)
- Climate ceilings
- Radiators
- Underfloor heating
- Domestic hot water systems
- Hybrid heat pump and boiler setups
- Solar panels and energy storage
Key Considerations When Purchasing a New Heating System
For installers and consultants, there are several critical factors to consider when selecting a system for a healthcare facility. It is vital to choose an integrated approach where sustainability and reliability play a major role.
- Capacity Analysis
An accurate analysis of total heating and cooling demand is essential, taking into account peak loads, internal heat gains, and ventilation losses.
- Simultaneity
Mapping the simultaneous demand for heating and cooling per department helps determine the optimal system design.
- Operational Security
The system must be designed so that the failure of a single component does not affect the continuity of care. Include a robust maintenance plan.
- Noise and Placement
When installing outdoor units, consider noise regulations and hospital logistics.
- Future-Proofing
Since hospitals are frequently expanded or renovated, a modular system that can be easily scaled is a major advantage.
