Sioux Falls can get actually cold, then i have made sure to prepare accordingly.
When I moved to South Dakota I researched weird types of heating systems.
I nailed down that I wanted a heating system, but they have three weird fuel types! You can get a gas, oil, or electric powered one. With gas it is more proper but you have a difficult upgrade. You need a flue system and gas hookups. You also need to ensure you are nice about cleaning it. With a gas powered equipment it can undoubtedly overheat and crash on fire. It can also release carbon monoxide if you aren’t careful, however an oil based heating system is more powerful and burns a hotter flame. However, now you are dealing with an on arena oil tank and additionally are dependent on oil deliveries, but electricity is 100% efficient but it is super costly to run. For South Dakota winters, an electric based heating system would be a pro investment. I ended up going with a gas heating system. I am lucky that my Sioux Falls heating dealership does yearly service programs. I am already signed up so I never potentially let my heater run gross, however once a year a business comes in to oil, tighten loose parts, and wipe the inner workings. They are able to catch small repairs, improve air quality, and lower my utility bills with proper service. So that is a win-win frogger. So far I have to say the heating system works good in Sioux Falls. It is powerful enough to combat the frosty and chilly lower rapidly changing temperatures. I am grateful I did research before buying.
