Baxi introduces AquaHeat HIUs for heat network projects 

Baxi introduces AquaHeat heat interface units (HIUs) as part of its Heat Network Transformation Program, aiming to promote high-performance, low-carbon heat networks towards net zero.

Baxi has introduced a comprehensive range of products and services, including AquaHeat heat interface units (HIUs), to offer a single point of contact for customers involved in heat network projects. The company provides comprehensive support at every stage, from feasibility studies to efficient system maintenance and optimisation.

Heat networks are an important part of the drive to decarbonise heat and hot water services in residential and commercial buildings. The government has a target to supply 20 percent of heat in buildings from heat networks by 2050, up from 2–3 percent. 

Baxi is implementing the Heat Network Transformation Program, which includes initiatives like Heat Network Zoning and stricter industry regulations, to ensure high-performance, low-carbon heat networks contribute to net zero. As heat networks are implemented in UK new build and renovation projects, Baxi offers services to support their correct implementation.

Perfect for use in new-build or retrofit multiple-occupancy buildings, campus heating systems, and district heat networks, Baxi’s comprehensive heat network solutions and services will support residential, public-sector, and commercial property developers and building owners in delivering low-carbon buildings.

Baxi Packaged Solutions is a prefabrication specialist that designs and manufactures pre-packaged plant rooms for centralised energy centres and utility cupboards for individual dwellings. These use heating and hot water solutions from Baxi’s brands Remeha and Heatrae Sadia, as well as heat pumps from the BDR Thermea Group manufacturing facilities in Europe.

As part of its heat network range, which includes thermal substations, Baxi is also launching AquaHeat, a new heat interface unit (HIU) for use in multiple occupancy projects such as apartments. The twin-plate HIUs are available in two outputs and can deliver indirect space heating and domestic hot water (DHW) for new builds and older homes. An indirect heat-only model is also available for use on commercial premises. Baxi’s heat network service is further enhanced by the UK launch of Mercurius Connected, a digital innovation developed and already available in Europe that will be able to remotely monitor, troubleshoot, and optimise the HIUs.

Baxi is leveraging the expertise of its parent company, BDR Thermea, which acquired heat network specialist Fortes Energy Systems last year. Baxi’s Integrated Thermal Solutions unit, led by Sales Director Stephen Hart, offers customers feasibility studies, system design, training, remote and onsite commissioning, and ongoing service support, including system commissioning and ongoing service support.

Stephen Hart said, “It is clear that heat networks will be one of the key routes to decarbonisation. Listening to our customers, it is equally evident that having a single point of contact will help them with the challenge of decarbonising heat and delivering low-carbon buildings. By offering an end-to-end heat network solutions service backed with expert advice from design to after-sales support, we can make the process simple, straightforward, and successful for our customers.”
