Guidelines for Energy Efficient Heating Systems

This whitepaper provides practical guidelines for heating professionals focused on creating complaint-free and energy-efficient two-pipe radiator heating systems in multi-family residential buildings. It addresses the relevance of these guidelines for retrofit, renovation, and new construction scenarios. The document outlines common challenges faced by heating professionals, such as noise complaints and inadequate heating comfort, which often stem from improperly balanced systems. It emphasizes the importance of hydronic balancing, proper design, and the selection of appropriate components to enhance system efficiency. The whitepaper also discusses the Energy Performance of Buildings Directive (EPBD) and its implications for reducing energy consumption across Europe. Additionally, it details the necessary steps for achieving effective hydronic balancing, including determining design flow rates and ensuring the correct operation of radiator thermostats. The document aims to equip heating professionals with the knowledge required to optimize heating systems while adhering to energy-saving regulations.
