With summer approaching here in WA state, I was thinking about putting together a fridge that I could not only use for lagering, but also a temp controlled space where I could ferment 10 gallons at a time and hold a good temp. I have been having low attenuation numbers with wyeast 1056, and i think that it is due to a higher fermentation temp and fluctuations in my house (65-74).
I recently converted to a chest freezer set-up so my old side by side fridge has nothing to do. here is my idea and I would love to hear some thoughts:
first, I work in HVAC, so my idea might be a little hard-core:
I was going to install a 1 heat/ 1 cool thermostat with a remote sensor for the fridge, energize the compresser off of a 24v coil relay that would power the entire fridge, and another relay that would energize a heat lamp and maybe a fan inside the fridge for heat in the winter months and maybe at night. the only thing that I am worried about is too drastic a temp gradient inside of the fridge. The only place that I have room for a lamp would be mounted in the top with a small fan blowing on it and if i placed the remote sensor halway down the side. I think that with a little fan circulating air I might take care of that... here is my big worry: light.
has anyone in the forum tried a heat lamp in this application, and if so will the light it produces have ill effects on my brew in either primary or secondary? I was planning on setting the heat/cool setpoints to 60 heat/ 66 cool. thanks in advance guys!
