Heat pumps are an established technology for heating and cooling as well as hot water production in many EU countries. In some countries, like Norway, Sweden, and Finland heat pumps are the dominant heating technology. In others, like Denmark, Switzerland, France or Austria, heat pumps are aspiring to move into that position. In a third group, with Germany being the prime example, heat pump technology has achieved a significant share in the new build market segment.
This flashlight on sales numbers reflects the characteristics of heat pumps. The technology is mature and ready for most application areas. Technological progress has increased the range of possible applications. In countries with sufficient time for market development and/or proper framework conditions, heat pumps have become a key heating and cooling technology.
Looking at the technology itself, a few trends are visible:
1. The large majority of units (>80%) are using air as their heat source.
2. Sanitary hot water heat pumps show the fastest growth. They help introduce renewable energy into traditional boiler installations.
3. Connectivity is becoming more and more important. Improved interfaces integrate heat pumps into home energy management systems and connect them in particular to PV systems.
4. The number of large heat pumps is increasing. In buildings with a dual use for heating and cooling heat pumps offer the highest efficiency. Bespoke heat pump solutions are the de-facto standard.
