Seasonal timing
The median first frost in Exeter arrives around October 19, a few days ahead of the beach towns and level with Stratham. A radiator that stayed cold last winter behaves identically once the system is running daily after that.

People also ask
A failed valve, a blocked run or trapped air are the usual candidates, and they look identical from the room. A technician identifies which before anything gets opened, since the wrong approach on a steam or hot-water radiator can make a mess or cause a burn.
They tend to be. A house that went from coal to oil to gas over a century has piping from every era, and what looks like a fault is sometimes just a section that was abandoned in place.
Capacity is less often the problem here than distribution. With 136 freezing nights and only 4 below zero, most systems have enough output; getting that output into every room is the harder part.
Shut the system down at the thermostat and get a technician out. Radiator water is hot enough to injure, and tightening fittings on a live system is a good way to turn a drip into a spray.
