We have a reasonably spacious hallway but it feels much less so so due an awkwardly located radiator. It's in the perfect place for some storage that we desperately need. We had a few quotes for moving the radiator to the opposite wall but it's an expensive and messy job that we're not going to do. The radiator has a thermostatic valve and the central heating is controlled by a wall thermostat in the living room. Would it be ok to turn it off and put our chosen furniture in from of it? The hallway doesn't get especially cold so it should be fine from that point of view but would it mess up the heating throughout the house and / or be very inefficient? Another option would be to remove completely but not replace the radiator I guess...?
