What is the ErP Regulation?
The ErP (Energy-related Products) Regulation is a European Union directive designed to ensure that energy-related products are presented to consumers in a more efficient, eco-friendly, and transparent manner. This regulation, which is also mandatory in Türkiye, primarily covers heating systems such as combi boilers, boilers, heat pumps, and water heaters.
The core goals of ErP are to make products standard that:
• Consume less energy
• Produce lower emissions
• Offer high operational efficiency
Why is Energy Efficiency So Important?
Energy efficiency means achieving the same heating comfort while consuming less natural gas or electricity. This is critical not only for the user’s budget but also for environmental sustainability.
Systems with high energy efficiency lead to:
• Lower natural gas bills
• Reduced carbon emissions
• More efficient use of energy resources
• Extended system lifespan in the long run
In this regard, the ErP Regulation acts as a guide, directing users toward more efficient products.
Which Products are Covered by ErP?
• Condensing combi boilers
• Central boiler systems (up to 400 kW)
• Heat pumps
• Cylinders and water heaters
• Circulation pumps used in heating systems
• Products falling below the minimum energy efficiency levels cannot be placed on the market.
What Changed in the Boiler Industry with ErP?
1. Non-Condensing Boilers Became History: The production and sale of conventional (non-condensing) boilers have largely ended, replaced by high-efficiency condensing boilers.
2. Energy Labels Became Mandatory: Every boiler must now be sold with an ErP energy label showing its energy class, noise level, and heating efficiency.
Understanding the ErP Energy Label
The label provides an at-a-glance view of performance:
• A++ → Maximum Efficiency
• A+ / A → High Efficiency (Condensing boilers are typically A-class or higher)
• B–G → Low Efficiency
What is a System Label? Why Does It Matter?
ErP evaluates not just a single device, but the entire system. For example, when a combi boiler is paired with a room thermostat and an outdoor sensor, the System Energy Label can move to a higher class.
👉 This translates to even greater savings in real-world usage.
Benefits of the ErP Regulation for the User
• Transparent information before purchase
• Lower energy bills
• Long-term operational cost advantages
• Eco-conscious heating solutions
Why are Condensing Boilers More Advantageous Under ErP?
Condensing boilers recover latent heat from waste gases that would otherwise be lost through the flue. This technology allows them to reach seasonal efficiency values over 100%, easily meeting ErP criteria and making them the standard solution for modern heating. Conclusion: ErP is the New Standard in Heating

Conclusion: ErP is the New Standard in Heating
With the ErP Regulation, heating systems have become more efficient, eco-friendly, and transparent. When choosing a boiler, you should consider not just the price, but also the energy class and system efficiency.
