ABSTRACT
In the UK, £32 billion is spent on heating every year and the heat consumption accounts for approximately a third of total greenhouse gas emissions. As space heating accounts for about 66% of the domestic energy bills (DECC, 2013a) and delivers approximate 74% of the carbon dioxide emissions, the majority of heat related activities are from fossil fuel consumption in the domestic sector (DECC, 2012). Many countries which have similar situation encourage the adaptation of renewable energy technologies.As part of 2009 EUwide action to increase the use of renewable energy, the UK government has committed to set 15% renewable energy target by 2020. This is a significant rise compared with approximate 2% in 2008.
