A colleague of mine was talking the other day about his heating set up at home, he lives in a social housing house which has a combi boiler and a hot water tank for 'emergency' use to supply hot water if the boiler fails.
I have not seen the setup my self but am confused as to why there is a 'dual system' in the house.
I only ask as I wish to update and change my own set up at home and am looking at different ways to achieve this!
