Propane-powered boilers can deliver heat through hydronic baseboard systems, in-floor hydronic systems, or even forced-air systems where the hot water from the boiler (instead of a furnace) acts as the heat source.
A propane-powered clothes dryer can make a big impact in your family's budget, compared with electric models.
For our full-service electrical contractor, no job is too big or too small; from wiring in a new outlet to lighting up a commercial building.
All of the pleasures of a real fire, with none of the hassles. That's the beauty of a propane fireplace.
Give your family greater comfort, security, and safety with a propane standby generator.
Propane power creates efficient, affordable ways to heat your outdoor living space and bring the comforts of home to your own backyard.
The warmth and comfort of propane furnaces can’t be matched. And with home/space heating being the biggest energy cost for most homes, it pays to invest in propane.
Propane-powered cooktops and ovens deliver instant heat, responsive control, and more even heat.
Superior offers a number of Propane tank sizes to meet a wide range of residential and commercial needs.
Propane uses less energy, saves money, and reduces your carbon footprint compared with electric water heaters. The only question left is: why haven’t you switched?
