New tinkering project. Can you guess what it is?
The current system is good for stabilising the cellar temperature during the summer (diurnal range is less than a degree or two) but the water tanks arent evaporating/cooling enough during extended warm spells to keep the cellar temp down low enough.
So Im going to change from an open water mass system, to a chilled closed loop one.
This lot will still run on the 25kWp of PV panels I have. Hopefully over extended periods the cellar temp can be kept a few extra degrees below ambient.
Always fun to experiment 🙂
Red is outside diurnal range throughout the summer, blue is inside the cellar diurnal range:
Similar data, but here you can see how the cellar temp rises during the summer above 20degrees at times (red/blue lines). Orange band is outdoor diurnal range.

Will connect the closed loop system to the pipes in the cellar
I’ve stopped putting wine down for the time being as have more pressing commitments at the moment but will return to that particularly pleasant hobby in the not too distant future.
I still have a couple of vignerons that I buy regularly from in Nantes, Montpellier and Bourgogne but if I’m honest it’s more quaffing wines and stuff ready to drink these days topped up with Naked wines if I run out between French trips.Posted 4 years ago
