Feel the Heat…
Nearly half the energy we use is used for heating and heat is a major component in our scenarios
Our models focus on the residential sector – residential heat is the largest component of natural gas demand
Our modelling has examined insulation, boilers, heat pumps and district heating
Non Heat 15%
Heat 44%
Trans-port 41%

GG: Highest scenario
All other scenarios
Heating systems often distressed purchases; consumers buy known technologies
Much uncertainty for this technology - some form of further intervention could see this market kick started
Millions
Widespread uptake will be dependent on RHI and consumer affordability
District Heating highlighted in Heat Strategy 2013; features in all scenarios

Key Messages
Legislative policy has delivered real savings to date
It could continue to drive change in the energy sector in the future
Consumer preferences and affordability will continue to determine the adoption of new technologies
