I have an isolated conservatory/winter garden that has underfloor heating with coolant. This takes quite a lot (I think anyway) of heat even though we've closed the door and only have it set to 7-8 degrees. Some have said that the building can get damaged if you don't have any heating on, but others say it shouldn't do that, though I haven't dared to take the risk. It's tiled floors and wood paneling and lots of glass windows. What do you think?
The building could be damaged if a water pipe freezes somewhere.
Otherwise, there's probably not much that can get damaged...
I have a garage that was originally built as a heated garage (i.e., waterborne heating, insulation, etc.). It remains cold all year round (and has done so for the past decades). The water is, in other words, drained from the radiators.
I haven't experienced any damage from this.
What you can consider is ventilating properly in the fall when the cold starts coming. Warm summer air that enters the space in July/August contains a lot of moisture, resulting in high relative humidity when the temperature begins to drop in the fall.
If you have a lot of tools and such, you want to keep it below 60% (to avoid corrosion).

As for microbial growth, it stops (or grows extremely slowly) if the temperature is below 0. So it's not during winter that it molds in garages, cold attics, and insulated conservatories. However, conditions for growth can be created. That is, moisture accumulates and creates favorable conditions when the temperature rises.Nyfniken said:
But as I wrote above: Make sure to ventilate out the damp late-summer air.
Okay, the underfloor heating in the sunroom contains some type of coolant so it can be turned off.
So, it's about if there are problems with moisture and mold. I already feel like it takes quite a lot of heat to keep it at 7-8 degrees. How would you have done it?
I also have a heated garage where I have tap water, so I keep it at about 5 degrees to prevent freezing, but I've considered emptying it as well. I don't really know how much it costs to maintain a little heat in these spaces. How can one estimate that somehow?
