Section 1: Overview of EU ErP Efficiency Standards

• The ErP (Energy-related Products Directive) mandates annual energy efficiency targets for appliances (SEPR/SCOP).
• Focus on low energy consumption, low carbon emissions, and high-performance operation.
• Sets requirements for system design, control logic, and hydraulic balancing in heat pump retrofit projects.

Section 2: Challenges in Retrofits of Historic Homes

• Thick stone or concrete walls limit signal and piping layouts.
• Existing gas boiler systems often have limited space and complex piping.
• Customers expect year-round comfort; traditional underfloor heating alone is insufficient.

Section 3: ErP-Compliant Heat Pump Retrofit Solutions

Key Solution Features:

• Efficient Heat Pump Selection: Ensure heat pumps meet EU ErP SCOP requirements for optimal seasonal efficiency.
• Zoning & Smart Control: Supports 8-zone control via master hub or RF thermostats for precise heating/cooling.
• Energy-Saving Dew Point Protection: Fixed supply water temperature logic ensures safe radiant cooling in summer.
• Pump & Valve Synergy: Automatic summer/winter mode switching maximizes SCOP.
• ROI & Brand Value: Year-round operation increases equipment utilization and shortens payback period; Efficient systems and improved comfort enhance brand image and customer satisfaction.

Section 4: Application Scenarios

• Premium residences, historic stone or concrete buildings.
• Boiler-to-heat pump (B2HP) conversion projects.
• Retrofit projects requiring year-round comfort and EU ErP compliance.
