My first post here so thanks for having me.
I have a custom-built, well insulated, cellar in the garage with a Cellar Pro 4200VSi cooling unit. During the spring and summer the cooling unit keeps the temperature constant at 55 F. During the winter the temperatures have slowly declined and are now at 43 F. There are no major fluctuations during the day—as mentioned, the temperature decline was very slow and gradual.
I do have wines that I’m planning to age for decades, and my question is: should I be thinking of a heating solution, and if so, any recommendations?
I’m contemplating between three main options:
1. Leave as is, since the daily temperature fluctuations are very minor (0-1 degrees). I don’t mind if it takes my wines longer to age; in fact, I prefer it to be the case. Perhaps during the spring and summer set the cooling unit to 50 F and this way reduce the difference between the minimum and maximum?
2. Replace the existing cooling unit with one that is both a cooling and a heating unit. The problem with this approach is that the existing unit wasn’t cheap. But if people think this is the ideal approach, any recommended unit?
3. Keep using the existing cooling unit. Turn it off during the winter (following the advice of the manufacturer’s support). Add a separate heating unit and activate it during the winter. If people think that this is the ideal approach, any recommended unit?
Thanks for any advice!
