You might consider using Peltier coolers. They are not as efficient as mechanical refrigeration, but for small spaces they could be what you need. They move heat best with a modest differential, just what you have. They are all over ebay, as separate elements or as "kits" including fans and...

And all this time I was thinking I was the only one who wasn't brewing while sitting on my livingroom sofa!

Keep an eye on the webpage - I'm making a couple of user-suggested changes (thanks Seven!) like deadband to reduce AC cycling (can be zero to some user set deg range) - and will be soon testing an option that will allow a simple variable resistor to set control for a 40F to 60F range. This...

That looks very nice. So you control the pump flow by restricting the flow I assume. About the dead space... It wouldn't work with the bottom heat, but if you combined an inline wort heater with something like the design of my lauter tun you would totally have it. I got tired of dead space and...

I'm growing them on a teepee/maypole. It works. Pole is 22feet tall, plants at the base of pole and in a ring 12' dia. I use some old galvanized trellis wire, anchored at each plant to a brick buried about 18" down. They get kind of congested at the top, and I can't just cut the wires to harvest...

Is there any downside to pumping when used with smaller volumes like 5gal? Is there any detrimental effect on the wort from the turbulence of the pump? That is a sweet solution and very tight temperature control. I suppose you could do gentle inline heating if you are pumping and skip the...

Brewslikeaking - I'm offering some unsolicited advice about the automation thing. Even a thin mash is going to show extreme gradients when heated from one spot (like the bottom). Ideally you would have an automated paddle to stir the mash to maintain a fairly even temperature. Where you place...

I found some old threads having to do with using the Coolbot and a window air conditioner for refrigeration of a coldroom. I got involved with some agriculture folks who were going to use a Coolbot to chill produce and when I looked into it and saw the simplicity of this concept I built a...

I realize this is an old thread but I found it and expect others may also find this. I will also post as a new thred in the Equipment category. I got involved with some agriculture folks who were going to use a Coldbot to chill produce and when I looked into it and saw the simplicity of this...
