Mixed willingness is found to adopt efficient technologies. While Developed Countries are positive towards building envelope technologies, appliances such as A-rated equipment or condensing boilers are negatively perceived ( [[#Yohanis--2012|Yohanis 2012]] ). In contrast, adopters in Asia are positive towards energy-saving appliances ( [[#Liao--2020|Liao et al. 2020]] ; [[#Spandagos--2020|Spandagos et al. 2020]] ).

Comfort, economic and ecological aspects, as well as information influence the purchase of a heating system ( [[#Claudy--2011|Claudy et al. 2011]] ; [[#Decker--2015|Decker and Menrad 2015]] ). Information and support from different stakeholders are the most relevant aspects in different geographical contexts ( [[#Hernandez-Roman--2017|Hernandez-Roman et al. 2017]] ; [[#Tumbaz--2018|Tumbaz and Moğulkoç 2018]] ; [[#Curtis--2018|Curtis et al. 2018]] ; [[#Bright--2019|Bright et al. 2019]] ; [[#Chu--2019|Chu and Wang 2019]] ).

Among high-income countries, economy aspects have positive effects, specially reductions in energy bills and financial incentives or subsidies ( [[#Chun--2013|Chun and Jiang 2013]] ; [[#Christidou--2014|Christidou et al. 2014]] ; [[#Mortensen--2016|Mortensen et al. 2016]] ; [[#Clancy--2017|Clancy et al. 2017]] ; [[#Ketchman--2018|Ketchman et al. 2018]] ). Having complementary technologies already in place also has positively affects adoption ( [[#Zografakis--2012|Zografakis et al. 2012]] ; [[#Clancy--2017|Clancy et al. 2017]] ), but performance and maintenance concerns appear as barriers ( [[#Qiu--2014|Qiu et al. 2014]] ). The solutions are positively perceived as high-technology innovative, to enhance status, and are supported by peers and own-environmental values ( [[#Mortensen--2016|Mortensen et al. 2016]] ; [[#Heiskanen--2017|Heiskanen and Matschoss 2017]] ; [[#Ketchman--2018|Ketchman et al. 2018]] ).
