Guide to designing and commissioning heating systems
Altecnic Ltd has launched a guide explaining how to design and commission heating systems for apartment buildings and district heating schemes, incorporating heat interface units, thermostatic radiator valves, and dirt and air separators.
The Altecnic Heat Network Design Guide aims to ensure specifiers, consultants, and contractors achieve the designed system performance post build, with a look at how maximum energy savings from HIUs can only be achieved if the system is designed, installed, and commissioned correctly.
The guide begins with a review of the latest independent resources and best practice for heat network design. These include:
- CIBSE CP1 (2020) Heat Network Code of Practice;
- UK Standard for Heat Interface Units;
- SAP Rating;
- low return temperatures;
- Building Regulations Considerations; and
- BSRIA Guide Information
Following this, the guide makes recommendations for HIU selection, primary pipe-work layout and sizing, primary flow rate calculations, radiator valves, dirt and air separators, and recommends particular system components. These are all provided with detailed descriptions as to the best practice of installation and product selection.
As a further tool, the guide details system sizing and HIU selection, including distinguishing between direct and indirect HIU’s, for specific building types..
Looking to the future, the guide advises on the commissioning of a heat network, and how to ensure that optimal efficiency is maintained throughout the life of the system.
