More often than not, older buildings will have inefficient heating systems or no heating systems at all. Therefore, there are construction opportunities for natural convection radiators that can be easily installed in existing buildings to meet increasing demand for increased thermal comfort. In January 2025, the EU's amended building efficiency policy began to encourage member states to develop strategies for renovating their buildings. It is anticipated that the renovation and new construction projects will increase demand for wall mounted, floor standing, and a variety of customized radiator systems over the next 3 to 5 years. This demand will be the strongest in areas where building owners are looking for heating system upgrades that require minimal electrical work and construction.
• Product Innovation: Heating system manufacturers are developing innovative methods to improve the design and functionality of radiators by improving the geometry, coatings, materials, and controls and developing systems that are quicker to heat and are more design flexible. The development of radiators that feature vertical designs with decorative finishes and smart thermostatic controls and can be installed with minimal construction increases the functionality and design of these systems. In 2025, the adoption of thermostatic radiator valves continued to increase throughout Europe though the adoption rate varied by country. Over the next 3 to 5 years, it is expected that natural convection radiators will become more competitive in the marketplace with both fan-assisted and electric radiator systems. This will occur through improved controls, installation hosting, and compatibility with low temperature heat pumps.
• Efficient Radiators: The growth of heat pumps promotes the need for radiators built to work effectively at lower temperatures. Modern radiator designs will remain comfortable while operating at even lower temperatures. In 2024, the total sales of heat pumps worldwide surpassed 100 million units. Due to the growth of the heat pump industry, 2024 was the first year that retrofit radiator systems started to gain some importance. Over the next 3 to 5 years, heat pumps will allow manufacturers the opportunity to enter the building renovation market by supplying radiators with high low temperature performance, and easy integration into existing systems.
• Competitive Pricing: Recent advances in the automation of metal forming, welding, coating, and quality control have allowed manufacturers to cut waste, shorten production time, and provide lower prices. Steel and aluminum radiators can be produced in a variety of standard sizes while allowing for customization for unique projects. Manufacturers in Europe and Asia spent 2025 focusing on production automation to overcome the challenges of hiring staff and achieving consistency. The next 3 to 5 years should bring an advantage in competitive pricing due to manufacturing efficiencies, allowing natural convection radiators to penetrate lower cost residential and commercial markets.

Challenges in this market include:

• The Variability of Raw Material Prices: Radiator manufacturers incur significant production costs for steel, aluminum, copper, coatings, and energy. There remains a high degree of uncertainty in the markets, and during 2025 the volatility of freight costs, energy costs and shifting trade conditions continued to challenge manufacturing procurement planning. Uncertainty in raw material costs in the coming three to five years will likely drive manufacturers to make changes in product design, increase the use of recycled materials, source from a wider range of suppliers, and sign longer term supply contracts. manufacturers who do not manage changing costs will become less competitive, and will be slow to expand their production capacity.
• Competition from Other Heating Technologies: Natural convection radiators are in competition with other technologies such as under-floor heating systems, fan-assisted emitters, infrared heating systems, and electric heating systems, etc. Min of these technologies can heat areas faster, provide more design flexibility, and easier control systems for zoning. Under-floor systems allow broader and uniform compliance in new buildings. For 2025, smart-home and heat-pump systems continue to increase in adoption in developed regions, making investing in heating systems more competitive. For the next 3 to 5 years constant innovation by radiator manufacturers in terms of low cost, easy to install systems that are quiet and smart ready will be key for survival in the industry.
• Installation and Regulation Complexities: Altering energy policies and requirements for product certifications, refrigerant policies, and building codes require continuous changes for the manufacture to comply and can slow down the development of a product. Even installation performance can vary greatly due to building insulation, piping sizes, water temperatures, balancing, thermostat configurations etc. In January 2025, the new changes to European building regulations have focused on lower operational emissions and improving building energy performance. Within the next three to five years, these regulation changes will require manufacturers to develop a greater depth of testing and documentation, and will need to develop additional training for installers and provide support for developing systems at the overall level. The rapidly changing requirements may cause smaller manufacturers to exit the market, and products that do not comply with the new regulations may have limited access to the construction and renovation markets.

The focus on energy efficiency, combined with renovation, and heat pump and product innovation drive the growth of natural convection radiator markets. These factors affect the residential, commercial, and institutional building markets. There may be limits to growth and profitability from the volatility of raw materials, alternative heating technologies, and regulations from different jurisdictions. In the next three to five years, suppliers who offer natural convection radiators with low-temperature performance, attractive designs, and quality, and a low total cost will be the market leaders. Success in the market will be based on the radiators' integration with heating systems, having a flexible supply chain, and the ability to meet more stringent sustainability and performance goals of buildings.
