Pantry: Is a heating coil sensible in controlled residential ventilation?

A pantry still makes a lot of sense nowadays. :)

No, in grandma's times that made sense.

My grandma is 97 and has a house with a larder - they call it a laundry room there. Apples and potatoes are also stored there. There is no heating loop in it. It is an extension that lies outside the building envelope. I would say it has nothing to do with today's construction methods.

Yes, that was more of an above-ground potato cellar :D. Nowadays, the pantry is the extended kitchen. Devices are stored there, vacuum robot station, food supplies, cleaning products, cat litter box, and feeding station. I'm very glad to have this room :)

Yes, we also have a pantry - nowadays it is located within the building envelope. There are no thermal bridges there and the radiant heat from the adjoining rooms is almost too warm. But I have never seen condensation water either in grandma's house or in ours. That only occurs when the humidity is very high and you then cool. Who cools their pantry?

Condensation occurs when the dew point is fallen below. The humidity is only one of the factors.

That's how it is. Grandma's pantry had nice mold stains on the outer wall.
