Heat Pump Day 2026: A day dedicated to heat pumps

Heat Pump Day, the European day dedicated to heat pumps and their role in transforming energy systems, returns on October 21, 2026. The initiative involves companies, technicians, associations, public bodies, researchers, and industry professionals through events, visits, information sessions, and online activities organized in several European countries.

Now in its third year , the event was created to raise awareness of heat pump technologies and highlight the industry's contribution to innovation, skilled employment, industrial competitiveness, and the electrification of consumption. For the HVACR industry, it also represents an opportunity to reflect on the evolution of refrigerants, components, maintenance, and technical expertise.

October 21st is a European day dedicated to technology

Heat Pump Day was launched in 2024 and brings together activities organized across Europe under a single initiative. The goal is not to focus attention on a single event, but to create a widespread day of information and discussion on heat pump applications.

In 2026, initiatives may include visits to factories and facilities, open days, information sessions, technical meetings, digital insights, and presentations of actual projects. The program also extends to the days leading up to October 21st, effectively transforming the event into a week of activities spread across the region.

This year's edition places particular attention on :

• employment and specialized skills;
• research and innovation;
• production of components and equipment;
• installation and maintenance;
• industrial and high-power applications;
• competitiveness of the European supply chain;
• reducing dependence on fossil fuels.

By 2025, the day had gathered over 100 activities in Europe, a sign of growing interest in technology.

Heat pumps and refrigeration share technologies and expertise

For the refrigeration sector, Heat Pump Day is not an event far removed from its professional field.

Heat pumps and refrigeration systems share many of the technological principles underlying their operation : compressors, exchangers, expansion valves, refrigerants and control systems are part of both applications.

The objective and operating conditions change, but the thermodynamic cycle remains closely related. In a refrigeration system, the primary concern is to extract heat from an environment or process; in a heat pump, the primary focus is on the energy released on the hot side.

This technological proximity makes the growth of heat pumps particularly relevant for refrigeration and HVACR technicians . The spread of new refrigerants, for example, requires increasingly transversal skills in:

• A2L and A3 fluids;
• CO₂ and natural refrigerants;
• safety and charge management;
• refrigerant recovery;
• reversible refrigeration circuits;
• electronic control;
• maintenance and diagnosis.

The evolution of heat pumps therefore contributes to expanding the professional field of refrigeration, especially in commercial and industrial applications.

Great interest in industrial heat pumps and heat recovery

One of the most interesting areas concerns large-capacity heat pumps , increasingly used to recover thermal energy from industrial processes, refrigeration systems and infrastructure.

In commercial and industrial refrigeration, there are numerous applications in which the heat extracted from the process is still dispersed through condensers or dissipation systems.

A heat pump can raise the temperature of this heat and make it usable for:

• domestic hot water;
• space heating;
• production processes;
• industrial washing;
• heat networks;
• preheating of process fluids.

The relationship between refrigeration production and heat recovery is thus becoming increasingly close. In supermarkets, the food industry, refrigerated warehouses, and other facilities with continuous cooling demand, integration can improve overall energy utilization.

Industrial and large-scale applications are among the themes that the 2026 day aims to highlight through projects, technical testimonials, and dedicated initiatives.

Training and maintenance at the heart of the sector's growth

The spread of heat pumps, however, requires a supply chain capable of properly installing and maintaining an increasing number of devices.

For this reason, alongside technology, Heat Pump Day 2026 dedicates space to the people who operate along the entire value chain : research, production, design, installation, maintenance and training.

For HVACR professionals, this is a particularly timely topic. Evolving refrigerant regulations and the growing use of fluids with varying flammability, pressure, and toxicity characteristics are increasing the need for specific technical expertise.

The growth of heat pumps will therefore depend not only on the industry's production capacity, but also on the availability of qualified installers and maintenance personnel capable of ensuring safety, efficiency, and performance throughout the systems' entire life cycle.

Heat Pump Day thus becomes not only a day of technological promotion, but also a moment to highlight the evolution of a supply chain that increasingly directly involves the world of refrigeration.
