What is the price of a HIU (Heat Interface Unit)?

An average price for a Heat Interface Unit can be from around £800 to £1500, this price can vary depending on the HIU type, performance of the unit and equipment provided. 


Using a twin plate HIU (indirect Heating & Domestic Hot Water) as an example, there are a few key factors impacting product price: 


  1. Product performance – a twin-plate HIU can be engineered for performance, this can result in larger plate heat exchangers, higher performing valves and sensors or more effective insulation. The BESA test regime for HIUs is an effective way of benchmarking product performance.  
  2. Pack contents – some HIUs will be delivered with accessories or fitting packs as standard, for example isolation valves, heat meters or first fix installation kits. 
  3. Connected services – HIUs can be delivered with a connected service package as standard, such services can provide the ability to remotely monitor and control products providing an advantage in after-sales service
