My elderly mom owns a three family home with one gas burner and pays for the tenants' heat/hot water bills. To make matters worse there's a thermometer in each tenants' apartment so they're able to control the temperature settings. Mom lives on a small fixed income and her heat/hot water bills are astronomical -- even worse this winter than in past years due to the extreme cold weather here in the northeast.
My questions is: Do 2 additional gas burners have to be installed in order to have separate billing for these apartments or is it possible to monitor heat/hot water consumption with the one existing burner. I've been unable to get through to our local utilities company due to the extreme cold and any advice on this would be appreciated.
thanks, Nanette
