When Some/All Bedrooms Lack Radiator

[Steven Booty]

Lately I've been walking through houses that have strange (by modern buildings) heating arrangments. One house had only a firebox in the kitchen while the 2nd floor bedrooms had nothing. I just offered on a duplex that has one boiler and only has a radiator in one bedroom in each unit (units are 1st floor and 2nd floor). Radiators are also in other rooms, too. It's just the one bedroom in each unit lacking a radiator.

Is this something that you usually do something about or is it typical to see how the current set up works out?

Thanks!
