When I went to visit my sister’s house, I couldn’t feel how chilly it was. I wasn’t expecting such low hot & cold temperatures, & I felt certainly unprepared. My sister likes to save money every way she can, which includes keeping her heating system turned off or running at a low temperature. It didn’t surprise me how chilly her apartment was considering the hot & cold temperatures outside, because I knew she wouldn’t have her heating system running at a normal temperature. Thankfully, she agreed to increase the temperature by a few degrees when she noticed how chilly I was. It didn’t take long for her apartment to hot up, after an hour, I started to get chilly again. I asked my sister if the heating system was still running, & she told me it wasn’t. Apparently, she turned the heating system down when everything warmed up, then she agreed to turn the heating system up a few degrees again, despite the fact that I noticed that she switched the heating system off again after the apartment warmed up. Although it wasn’t my house, I thought this was certainly aggravating. When I felt her home getting chilly again, I told my sister that she needed to leave the heating system on & let it run always; Every time she turned it off & it got certainly cold, her heating system had to work extra hard to heat the entire home all over again. She’d save more money by letting the heating system run at one temperature! Of course, she refused to listen to me because she assumed I was wrong & she’d end up spending more money.
