BSRIA delighted to announce BESA approval for Heat Interface Unit TestingOctober 2018

Colin Judd Principal Research Engineer

BSRIA is delighted to announce it has become a BESA (Building Engineering Services Association) approved laboratory for Heat Interface Unit (HIU) testing in accordance with BESA Technical Standard: UK HIU Test Regime – October 2018.

The test regime covers the performance of HIUs designed for space heating and domestic hot water (DHW) production, which includes pressure testing, static, dynamic, keep warm and low flow DHW tests. Provision is made in the regime to carry out testing at both high and low district heating (DH) temperatures.

Testing is carried out in BSRIA’s dedicated environmental chamber, where clients can witness the testing and observe live test data, while also using the facility for product development purposes.

Colin Judd, Senior Test Engineer, said:

“Attaining BESA approval for HIU testing further extends BSRIA’s product test offering and meets a growing need within the industry to comply with the BESA UK HIU Test Regime. We are delighted to be able to offer this service and look forward to working with new and existing clients.”

HIUs extract heat from district heating networks to feed individual buildings and dwellings. How they perform is central to the overall efficiency of the heat network in a district heating scheme. The standard was developed to help developers of UK heat networks procure HIUs based on comparative performance data.

BESA is the UK's leading trade organisation for building engineering services contractors – representing the interests of firms active in the design, installation, commissioning, maintenance, control and management of engineering systems and services in buildings.
