Overview
EN 1148:1998 (CEN) specifies uniform test procedures for establishing the performance data of series-produced water-to-water heat exchangers intended for district heating appliances. The standard defines how to determine and report product identification, core performance characteristics, and pressure drop. It is a measurement and data-specification standard and does not cover technical safety aspects. EN 1148 was adopted nationally (e.g., SIST EN 1148:1999).
Keywords: EN 1148, water-to-water heat exchangers, district heating, test procedures, performance data, pressure drop, product identification, heat exchanger testing.
Key Topics
- Scope and applicability: applies to series-produced water-to-water heat exchangers used in district heating systems.
- Product identification: standardized methods for identifying and documenting model, serial numbers and other traceability data required on test reports and datasheets.
- Performance characteristics: uniform test methods to determine heat transfer performance and to generate reliable, comparable performance data for rating and specification.
- Pressure drop measurement: procedures to measure pressure loss across primary and secondary circuits under defined test conditions - essential for pump and hydraulic system design.
- Test reporting: consistent format and data elements to report results so manufacturers, test laboratories and end users can compare products objectively.
- Scope limitation: excludes requirements on safety, materials selection, and installation - those topics are dealt with in other standards or regulations.
Applications
EN 1148 is used by:
- Manufacturers for type testing, production verification and preparation of product datasheets.
- Independent test laboratories to run reproducible heat exchanger tests and produce accredited reports.
- District heating utilities and system designers to select and size heat exchangers based on comparable performance data and pressure-drop information.
- Specifiers and procurement teams to create objective tender requirements and acceptance criteria.
- Consultants and modelers who require validated performance inputs for system simulations and hydraulic calculations.
Practical value: ensures consistency in heat exchanger performance claims, aids correct pump sizing (via pressure-drop data), and improves traceability through standardized product identification.
Related Standards
EN 1148 complements other CEN/EN standards covering safety, materials, installation, and system-level requirements for heating equipment.
