20 Energy Saving Facts

​​​​​​​​​​​​​​Hydronic optimisation can be the key to reducing energy consumption 

Discover how to simply and effectively reduce energy use 

20 useful facts that won’t waste your energy

           System optimisation: Production
  1. Lowering the chiller water supply by 1°C reduces system efficiency by 4%
  2. A lower inlet chiller return temperature can impact the COP ( the ratio that measures the energy efficiency in heating performance) significantly, reducing it by up to 15%
  3. Dirt deposits, sludge, scale deposits and metallic residues, can affect chiller efficiency by up to 5% and reduce system pressure by up to 10%
  4. Overflow can reduce the condensing period by up to 20% and negatively impact efficiency in condensing boilers
  5. 1mm of scale deposit can increase boiler energy consumption by as much as 9%

    System Optimisation: Distribution ​
  6. Electrical pumping costs (constant flow distribution) in cooling systems can account for as much ​as 7 to 17% of overall energy consumption​
  7. Electrical pumping cost can be reduced by as much as 40% in a correctly balanced HVAC system
  8. Increasing the total pump head to compensate for an underflow of 20% to some terminal units can increase the overall electrical pump consumption by as much as 95%
  9. Energy savings of up to 35% can be achieved when a heating or cooling system is correctly balanced
  10. A rise in system water temperature of 1°C can result in 3% higher pipe heat loss
  11. Corrosion and dirt deposits in pipes can increase electrical pumping costs in heating and cooling systems by as much as 35% in the first years after installation

    System Optimisation: Dissipation 
  12. ​A 1°C rise in room temperatures can increase overall energy consumption by between 6 – 11% annually in heating systems
  13. A 1°C reduction in room temperatures can increase overall energy consumption by between 12 – 18% annually in cooling systems
  14. Interactive On/Off control systems can lead to as much as a 7% increase in energy consumption
  15. Combining centralised set-back programmes with local set-back devices can deliver energy savings of up to 20%
  16. Every additional hour of start-up time (starting up earlier than necessary) can increase total heating energy consumption by up to 1.25%
  17. Thermostatic radiator valves deliver significant energy savings – reducing consumption by as much as 15% compared with manual va​lves
  18. Air build up in radiators can reduce heat output by up to 80%
  19. Replacing old-style thermostatic heads (those produced before 1988) with modern versions can achieve up to 7% energy savings
  20. Installing individual room temperature controls in underfloor heating systems can reduce energy consumption by up to 20%
