Climate controls for car garage

[Chazbo69]

I am planning a 60 * 120 garage for my collector cars in WI and would like to hear your thoughts on climate control systems for the garage. The cold in the winter and humidity in summer makes it tough to control. Also, any thoughts on exhaust systems for auto CO2 in my garage? Thank you in advance for any input.

So I have to ask where in WI? in floor hear is what i went with in my 52x96. i don't plan on conditioning the shop but i've heard if you don't need it cooled a few decent dehumidifiers will keep the humidity down if it stays closed up.

Not to far away. I've done autocross at USA International Raceway quite a few times. The most fun you can have for 35 bucks. I usually get in 10 runs at least and the course is usually around a mile long. If you haven't been out there for a autocross you should check it out. They are usually hosted by the Fox Valley Sports Car Club www.FVSCC.com or the Central Wisconsin Sports Car Club. www.CWSCC.com.

Here's a vid of one of the times I was there. I'm running my 88 shadow which I use for ice racing in the winter so it isn't terribly fast.

IDK if your planning on cooling in the summer, but if you use a small package HVAC unit, make sure you get one with an economizer. Also, if you're planning on an exhaust system, you might want to look at a unit that can supply tempered air from 100% outside air for when the exhaust fan is on, but you're not calling for heat.

First and most important, you absolutely must have a vapor barrier under the floor !

The ultimate would be a combination of radiant floor heating and forced air. The radiant heat would control the "ambient" temp and the forced air will give you quick recovery in winter when you open the door(s) plus allow A/C in summer.

You could achieve this with a couple mini-split heat pumps. Heat exchanger from the heat pump or a gas fired boiler for the radiant heat. With that size you are probably going to need at least 4 indoor air handlers.

You should also get some quotes on geothermal heat pump(s). Expensive to install, but they very inexpensive to operate.

If I were to build a new shop today, I'd have radiant heat along with forced air. IMO the radiant heat is GREAT on old bones and very efficient. The down side is the humidity.

My Dad has radiant heat in his shop and the both and hand washes his vehicles once a week. After a few years, I can see the byproduct of the humidity on his collector cars. Additionally, if you do have to open the shop up during the winter, the temp recovery is a little long in the tooth.

While dehumidifiers are great, there is nothing better than heat and the air moving from it to dry everything out. I would have to imagine it is much better on the drywall and the structure itself.

Get yourself some A/C while your at it! Swing for the fence

60 x 120 sounds like quite a shop! But the downside is 7200 sqft comes with a hefty heating bill!
In floor heating definatly. . But rather than a natural gas fired boiler.. look into solar.. evacuated glass tube solar collectors can make heat down to -30... I'm considering this system with a forced air back up, and I'm only heating 800 sqft
