General Understanding
- What is a heat pump and how does it work?
A heat pump transfers heat from a low-temperature source to a higher-temperature destination using electricity. It can be used for both heating and cooling.
For more information, see:
– Learn more about what a heat pump is and how a heat pump work. - What types of heat pumps exist?
There are many different types of heat pumps that use different heat sources, with wide array of capacities for different purposes. Common types include air-source, ground-source, water-source, and heat recovery systems.

– Learn more about the different types of heat pumps and their applications. - Where can heat pumps be used?
This technology is very versatile and can be used in many different contexts, from providing a pleasant ambient temperature in a home, to high temperature industrial processes. They are applicable in residential buildings, commercial facilities, industrial processes, and district heating systems and also other types of applications.

🌡️ Performance & Efficiency
- Are heat pumps efficient in cold climates?
Yes, modern heat pumps are designed to operate efficiently even in far below sub-zero temperatures, though performance may vary by model and installation. For instance, In Europe, the Nordic countries with lowest outdoor temperatures have the largest penetration of heat pumps.

– Project 41: Cold Climate Heat Pumps Improving low ambient temperature performance of air-source heat pumps - Can heat pumps be used in existing buildings or only new ones?
Yes, heat pumps can be applied effectively in existing buildings, single family as well as multi family buildings. In some cases, the most cost optimal solution is to retrofit the building envelope and the heat distribution system prior to installing the heat pump. However, in many cases the heat pumps can be installed directly into the existing building.
More information is available in the Buildings section of our Knowledge Hub, for research results see:
– Project 50: Heat Pumps in Multi-Family Buildings for Space Heating and Domestic Hot Water (DHW)
– Project 62: Heat pumps for multi-family residential buildings in cities
– Heat pumps in existing residential buildings - Can heat pumps be used together with all type of distribution systems?
Heat pumps are compatible with various heat distribution systems from district heating and cooling to more local solutions such as radiators, fan coils and underfloor heating. In fact, the lower temperature of the distribution system, the higher efficiency of the heat pump.
You can always find more information in the System Integration & Flexibility section of the Knowledge Hub. - Do heat pumps save money compared to traditional heating systems?
In most cases, especially on the long term. This depends on the overall installation cost as well as the cost of electricity compared to the other energy sources. However, when combined with renewable cost-efficient electricity sources and properly insulated buildings heat pumps can save a lot of money.
For more information please visit the “cities and communities” section of the Knowledge Hub. - Can heat pumps be used in industrial applications at high temperatures?
Yes, they can. Heat pumps have most commonly been used for temperature levels up to 100°C. However new technologies are now going up to 140°C, and will soon reach 200°C and higher.

– Project 48: Industrial Heat Pumps, Second Phase
– Project 58: High-Temperature Heat Pumps
– Project 58: Industrial High-Temperature Heat Pumps - Are heat pumps noisy?
Noise levels have significantly decreased with newer models. Many systems operate quietly enough for residential use without disturbance. Different policies are regulating maximum noise levels and research is ongoing to make products and systems even more silent.

– Project 63: Placement Impact on Heat Pump Acoustics - Can a heat pump be used for cooling as well?
Absolutely! Heat pumps are reversible and can provide cooling in summer and heating in winter. Under some circumstances they can provide heating and cooling at the same time.
💰 Cost & Incentives
- What are the installation costs?
Costs vary depending on the type of system, building size, and complexity of installation. - Are there financial incentives or rebates?
Yes. In many regions, including Europe, China and the U.S., there are federal, state, and local incentives. Read more about Markets and Policies.
