Radiant Heat


I am having built an extension onto my barn to be used for storage -- specifically bottled and cased wine -- I own a winery.
My contractor wants me to select the type of heating and cost is the major factor. I thought I wanted overhead radiant tube heating because it is much less expensive than slab radiant heat. I do have natural gas in the winery but am concerned about the effect of the heat on the cased wine. The size of the extension is approx. 36' x 40' with 12' high ceilings. The optimum temperature is 55 degrees. Any advice? Also, is there a way to cool with either of these methods? What about the cost?

Why not use a simple forced air furnace set up. Initial cost may be a little more but it can be used for both heating and cooling.

Radiant Heat


Radiant heat from the ceiling will tend to warm up your wine.
Since radiant heat doesn't warm air. It warms objects. Like cases. Weather or not its wine, radiant heat does not care.

Radiant floor heat would be slightly better. Since the air will pick up heat from the warm surface of the floor itself.
Keep cases raised off the floor by several inches(6").

Radiant cooling can work. But. You need another method to lower the dew point of the air in the building. Such as, a forced air conditioner, or a large dehumidifier.

Of course. To use radiant cooling requires you to have a chiller.
Which is ok. You can use a reverse cycle chiller to provide radiant floor heating and your radiant cooling. And also use it for a chilled water coil to lower the dew point in the building.

However. it will NOT be a cheap system.

If you are only needing 55deg and A/C you could concider a mini split system. Look at mrslim.com
