The Future of Energy Efficiency for Heating & Hot Water Production
Energy Saving Technologies
The Importance of Improving Energy Efficiency The Regensw Road to 2020 document states: • "Reducing energy demand and increasing energy efficiency will play a central role.." • "Energy demand reduction and energy efficiency measures are usually the cheapest and quickest routes to reducing carbon emissions" • ".. the absence of a successful energy demand reduction program will require an additional 4TWh of renewable energy.." There is more than 4TWh to be saved .....
Energy Saving Technologies
The Key to Energy Efficiency • Must recognise that boilers are not as efficient as they could be • Must recognise the true scope for energy efficiency savings • Savings from reduced energy costs directly affect profitability • Low risk approach • Immediate payback
Energy Saving Technologies
An Independent View • Zenex commissioned an examination of the efficiency of hot water production • The examination was performed by – TUV NEL World leading provider of knowledge consulting, research, test and programme management • A full copy of this report is available on request from Zenex
