Seen lovely house but has a back boiler in lounge. It's sooo ugly (and is the focal point of whole room) and would really like to be able to change the front for something abit more modern but worried might not be possible. Also, are they any good, reliable, economical etc? I googled it and things about carbon monoxide came up - arghhh! Never come across one of these before and no-one I know has one. Any experience anyone?
