Inta's Hiper II Achieves Landmark Success as First Heat Interface Unit to Pass BESA Regime 3 Test
Inta’s Hiper II has achieved a groundbreaking milestone by becoming the first heat interface unit (HIU) to pass the stringent BESA Regime 3 Test, a pivotal evaluation in the construction and HVAC industries. This rigorous pass/fail test, newly implemented by the Building Engineering Services Association (BESA), sets a high standard for performance and efficiency in the realm of heat interface units.
The Hiper II’s comprehensive assessment targeted specific operational capabilities, such as space heating and domestic hot water (DHW) delivery under various conditions. The unit excelled across all tests, ensuring reliable performance even under high demand and low flow scenarios. Notably, the Hiper II demonstrated exceptional performance in maintaining optimal Volume Weighted Average Return Temperatures (VWART), a critical factor in energy efficiency and system longevity.
Enertek International Limited, the independent testing laboratory, confirmed that the Hiper II met all performance criteria, with specific tests highlighting its capabilities in both high and low-temperature operations. The results indicate that the Hiper II not only meets but exceeds current industry standards, making it a top choice for residential and commercial installations where efficiency and reliability are paramount.
Neil Stead, National Specification Manager at Inta, said: “We are incredibly proud that the Hiper II is the first HIU to pass the BESA Regime 3 Test. This achievement underscores our commitment to delivering high-quality, efficient solutions that meet the evolving needs of the construction industry.”
This achievement places the Hiper II as the first HIU on the BESA register, setting a benchmark for future developments in heat interface technology. For construction professionals, this means access to a proven, high-performance solution that supports sustainable building practices and enhances overall system performance.
As the construction industry continues to evolve with a focus on energy efficiency and sustainability, Intatec’s Hiper II stands out as a leader in innovation and quality. This certification is not only a testament to Intatec’s commitment to excellence but also a significant step forward for the industry at large.
A BESA report for heat interface units (HIUs) is a document that shows the performance and compliance of an HIU according to the UK’s Test Regime for Heat Interface Units, which is developed by the Building Engineering Services Association (BESA). The purpose of the BESA report is to help heat network developers, operators, and customers evaluate and compare the quality and efficiency of different HIUs in the UK market.
The BESA report includes various metrics, such as the annual volume weighted return temperature (VWART), the speed of temperature stabilisation, and the evidence of reliability.
| High temperature test results | °C |
|---|---|
| DHW VWART | 13 |
| Standby VWART | 38 |
| Space Heating VWART | 40 |
| Overall result | 30 |
| Low temperature test results | °C |
|---|---|
| DHW VWART | 20 |
| Standby VWART | 39 |
| Space Heating VWART | 37 |
| Overall result | 30 |
