Replacing boilers with heat pumps to decarbonise buildings and industry

Replacing conventional gas or oil boilers with high-efficiency air-to-water heat pumps is one of the most effective ways to reduce energy consumption, cut CO₂ emissions and speed up the decarbonisation of buildings and industrial facilities.

Air-to-water heat pumps use the energy contained in the outdoor air (air-source energy) to produce heating, cooling and domestic hot water with high energy efficiency. Because they use natural refrigerants such as R290 (propane) and refrigerants with a very low Global Warming Potential (GWP), they offer a solution ready for the evolution of European fluorinated gas regulations and for new energy efficiency and sustainability targets.

The Enerblue range produces hot water up to 70 ºC with R290 refrigerant and up to 80 ºC with its high-temperature heat pumps, making it easier to replace many existing heating systems without significant changes to the hydraulic installation.

As well as reducing primary energy consumption and carbon emissions, this technology supports the electrification of installations and their integration with renewable energy such as photovoltaics, helping to reduce dependence on fossil fuels and optimise running costs throughout the building’s life.

Benefits of the technology

• Gas or oil boilers replaced with high-efficiency heat pumps.
• Renewable energy from the air (air-source energy) used for heating and hot water.
• Hot water production up to 70 ºC with the natural refrigerant R290.
• Hot water production up to 80 ºC for high-temperature applications.
• Lower energy consumption and CO₂ emissions.
• Natural and very low GWP refrigerants, ready for the European fluorinated gas regulations.
• Integration with photovoltaic installations and energy management systems.
• Configurable solutions to meet the requirements of each project.

Applications

Enerblue heat pumps are a particularly suitable solution for boiler replacement and electrification projects in:

• Hotels and resorts.
• Hospitals and healthcare centres.
• Office and commercial buildings.
• Sports facilities and heated swimming pools.
• Industry and production processes.
• Logistics centres and retail buildings.
• Energy refurbishment and building decarbonisation projects.

Heat pumps have become one of the key technologies for the energy transition in the HVAC sector. Their ability to use a renewable energy source such as the air, together with high energy efficiency and low-impact refrigerants, makes it possible to gradually replace traditional combustion systems with fully electrified, more sustainable solutions that are ready for the energy challenges of the future.
