ᐅ Pantry: Is a heating loop useful with a mechanical ventilation system?

Hello everyone,

we plan to install a heating cable along the wall in our pantry. I understand that in the past, this was useful to prevent moist air from the kitchen from condensing on the cooler pantry wall.

However, we have a mechanical ventilation system with exhaust air in the pantry – does the heating cable still make sense in this case, or can I do without it?

A pantry still makes a lot of sense today. 🙂

No, that made sense back in grandma’s days.

My grandmother is 97 and has a house with a pantry—in her case, it’s called a utility room. Apples and potatoes are also stored there. There is no heating loop inside. It is an extension located outside the building envelope. I would say that has nothing in common with today’s construction methods.

Yes, that was more like an above-ground potato cellar 😀. Nowadays, a pantry is an extension of the kitchen. Appliances are stored there, along with the robot vacuum 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 adjacent rooms is almost too warm. However, I have never seen condensation in either my grandmother’s house or ours. It only occurs when the humidity is very high and cooling is applied. Who cools their pantry anyway?

Condensation occurs when the dew point is reached. Humidity is just one of the factors.

That's how it is. Grandma’s pantry had noticeable mold growth on the exterior wall.
