humidity in garage
My system only runs 12 hours a day, in 4 runs of 3 hours each. There are however 4 large ceiling fans (0.85 amps each) that run 24/7, this helps keep the air mixed and more uniform in temp. and humidity level.
The water pump is a small shallow well pump, originally designed for a 1/2 hp. motor but I got it free because the motor was toast, so I put a 1/4 hp on it since I didn't need the volume or pressure it was designed for, and am only running with about a 8' total lift, being about 3' of suction and 5' of head.
The furnace fan blower is out of a very small unit, the motor only draws 3 amps.
The system runs all year since the ground water never drops below about 50° F. even in the winter, so I am gaining some heat, between that and 2 dark-painted south facing 12'x12' doors the shop will not go below freezing regardless of the weather, and on a sunny day will be 15° - 20° above the outside temperature.
Best of luck.

humidity in garage
A fellow near here built an underground house a number of years back. He just dug into a south facing hillside a bit and then started pouring concrete, sort of like an upside-down swimming pool. He then dug a large pond and buried the structure with the spoils from the excavation.
The neat part is his HVAC system. He put in many large 'chimneys' for lack of a better term, each one just tall enough to clear the surface, and each is topped with a plexiglass dome that has forms a parabolic lens. The inside of each chimney is lined with a moveable curved panel of black aluminum that runs around the inside. When he wants heat, he rtates the panel till it's in the sunshine, when it's too hot (rarely) he moves it out of the sunshine. A ceiling fan below moves the heat around.
His 'cooling' system is a long set of pipes that runs underground for quite some distance then into the house. When he wants cooling he can open the chimneys and pump the cool air in, forcing the hot air out.
He heats about 3,000 sq. feet with a small wood stove and nothing more.
Best of luck.
