About a third of the UK’s energy consumption is used for heating or producing hot water and a significant proportion of this is provided by commercial boiler plant.
Many buildings may still be using very old hot water boilers that had an operating efficiency of only about 70% when first installed and which will now be worse due to poor maintenance. Boilers therefore offer energy saving opportunities including boiler replacement and boiler optimisation.
Typically, energy improvements of 10% or more can be made relatively easily through the installation of optimisation equipment and the financial rewards of these often have a very short payback.
Longer-term measures are also well worth considering as new condensing boilers can achieve efficiencies of over 90% and consequently pay for themselves from the energy savings they deliver.
