shed heating
MrDavo:
I agree with what’s been said - nothing ever got rusty by being cold, it’s condensation that makes cold metal stuff in the garage get wet. I have one of those concrete garages as well, but I drilled air vents into the wooden gable ends. My attic used to get wet through, until I removed a large amount of old clothing stuffed into the eaves by the previous owner to cut draughts, never had a problem since. A customer who owns several houses told me that if he leaves a house empty he always cracks open a window to keep air circulating.
I have a dehumidifier in the garage but when it’s brass monkeys cold it doesn’t work at all. Sudden temperature change is the enemy.
As a kid I had a Venus Fly Trap for a while, I used to feed it flies and bits of sausage. I think it lasted as long as a fairground goldfish.

Trouble is modern houses lofts tend to be so well insulated that there is no air flow in the loft area
My parents had a old cottage and it was so open under the eves birds used to nest in the loft and mice would come in for the winter too
Like I said earlier the north side roof felt on a frosty cold day used to drip condensation like this as there was no air flow and no sun to warm this side of the roof
(Mates place was the same and he had puddles on the boarded area
We both fitted these and problem is complete resolved
Yes may be a slight bit of heat loss but now the ventilation is much better( you can now feel a slight draft in the loft area) And better than a damp loft / roof joists etc

For our bungalow we fitted one of these in the loft, the bungalow used to suffer terribly from condensation, especially after we upgraded the insulation. We made sure that room and soffit vents were clear fitted one of these and have had no problem since.

I have spent most of my working life trying to stop condensation in customers homes. Hardly any of them understand when I tell them you need airflow. Most rentals I look after suffer badly because people insist on blocking every gap they see and then drying there washing on the radiators.
I once worked on a new build care home that was filled with mosquitos 🦟 Every night before I went home I would crank up the heat and open windows and every night the site agent would shut them behind me. In the morning water would be pouring out of lights and sockets. The paint on the walls would be wet for days.

Heat pump heated homes will need something close to a sealed house in order to work. I believe new homes need to pass some sort of air seal test to meet regulations. Roof venting seems to be a thing of the past. When our house had the roof rebuilt after our fire it had to meet current building control regulations that included not only Kingspan type rafter insulation but all the upstairs ceiling plaster boarding was bonded with 50mm Kingspan. Our house retains so much heat that in the summer it's tropical if we do not open our upstairs windows. only real venting we have is a double air brick behind a radiator in our lounge a remnant from our old back boiler plus an air brick behind our kitchen cupboards for the gas hob.
