“The Nelsons' shop is split into three zones,” notes McMurray. “If there is any variation in what you need for heat in areas segregated from the rest of the shop, it's worth thinking about zone heating,” says Hellevang. Where appropriate, Hellevang and McMurray recommend using zone heating. “If a floor heating and forced air system is used, the heating requirement may be divided between the two.” “A 40×50-foot shop would require about a 100,000 Btu-per-hour heating system,” Hellevang says.
Ultimately, the size and type of heating system you choose will depend on the size of the shop, how often the shop is used, and how often large doors will be opened and closed.Īccording to Kenneth Hellevang, North Dakota State University, the heating system for a shop should provide about 50 Btu per square foot per hour depending on desired shop temperature and building insulation level. “We can open the large door on a cold day to bring in a piece of equipment, shut it, and within five to 10 minutes, the shop is back to 60☏.” What's the feature the brothers like most? “The best part is that the floor is warm so our feet are always warm,” says David Nelson. water into that floor, and it's maintaining +60☏. “We talked with people who installed in-floor heat, and they said they really liked it,” says David Nelson. “By going with radiant heat through the concrete, you can heat an area the size of the Nelsons' shop very cost effectively.” “My initial thought was that they needed to do this radiantly in the mass,” he says. Of the three, McMurray recommended in-floor heat for the Nelsons' shop. Because heat rises and heat is produced at the top of the room, this system is relatively inefficient. Most of the time this system hangs from the ceiling away from objects that can overheat. This system doesn't heat objects but rather the air, and basically it uses a flame to heat the air. It heats the object from the top down.”įorced Air.
“It's the one that, as you walk into a building, you get blasted with heat. “Radiant tube heat, or infrared heat, is a heater that hangs from the ceiling with the reflectors,” says McMurray. That's because the flame is enclosed and the system is only heated to around 130☏. Boilers can be placed just about anywhere. “One of the biggest advantages of this system is that the entire floor is warm,” says McMurray.

This system uses water to carry heat from a boiler unit through a series of pipes placed under a floor or embedded in a concrete floor. McMurray says there are basically three types of systems to choose from. “We laid out the heating, and I broke it down as to what their best options were for a shop that large,” says McMurray, who owns McEzs, a plumbing, heating, and refrigeration business in Meservey, Iowa.

Brothers David, Dennis, and Neal turned to Chris McMurray for guidance on how to heat their 80×80-foot building. When the Nelsons of Belmond, Iowa, built their shop in 2008, a top consideration was how they would keep it warm in colder months. Markets Analysis Back to Markets Analysis.
