Hot-water boost to heat network efficiency

Jacobs has designed a Generation 4.5 heat network that uses an innovative boost electrode to deliver domestic hot water, allowing the system to operate efficiently at a 45°C flow temperature for 80% of the year. The company’s Adam Selvey FCIBSE explains how it works

The hidden cost of poor pipework insulation

Pipework thermal insulation is often overlooked, but can have a devastating impact on system performance if not specified, installed or maintained correctly. Kaizen Energy Consultancy’s Lawrence Leask and TICA’s Chris Ridge say following insulation best practice is a low-hanging fruit when it comes to HVAC efficiency

Testing the limits: lowering operating temperatures

Lowering operating temperatures will be essential if existing buildings are to plug into the next generation of heat networks. FairHeat’s Simran Chaggar drops the boiler setpoints in two commercial buildings to see how they cope
