Zehnder’s radiant heating achieve better performance and efficiency

Zehnder’s Carboline range of radiant-heating panels is based on a construction that is said to make them considerably more efficient than other panels. These panels are served by hot water and can exchange up to 95% of the heat from the water, compared with a claimed 80 to 84% for a standard panel. They can also be used for cooling with similar heat-exchange efficiency.

Winner of the 2011 CIBSE award for energy-using products, Carboline panels consist of copper tubes embedded into a compressed graphite panel. This patented high-performance thermal element is then bonded into a galvanised sheet-steel casing. The overall construction achieves extremely event heat distribution with exceptional controllability.

Radiant heating can achieve comfort with an air temperature 3 K lower than systems that are largely based on convection. They also react rapidly. The combined benefit is to reduce energy consumption for space heating by around 44%.

Grenfell is the building industry's Piper Alpha says CIBSE

The recent passage of the Building Safety Act is a welcome recognition of the fact that making safe buildings is a highly skilled operation says the Chartered Institution of Building Services Engineers, endorsing the need for more effective regulation and a profound change in culture.

Underlying project-starts uptick indicates gradual recovery, Glenigan data suggests

  • 13% rise in detailed planning approvals against the preceding three months
  • 18% decline in main contract awards against the previous year
  • 9% increase in underlying starts during the three months to May

Glenigan has released the June 2022 edition of its Construction Review.
