i have been asked to write a report for an investor on a property he is looking at purchasing. This might be a daft question but in a property with full gas central heating why would a property owner have fitted one of these??? https://www.dimplex.co.uk/sites/default/files/assets//EDL%20UK%20data%20sheet%20v0.5.pdf Surely the green benefits are negated by the fact that they still have gas CH. Am I missing something??
