Cleaner heaters

I was in the hospital recently, to visit a friend.  She had been put in the hospital because she had pneumonia.  I was legitimately anxious about her because I had recently been to visit her.  When I arrived, she was cocooned in blankets from chin to toe. She told me she was so cold so was shivering.  I thought the room was quite comfortable in addition to I was anxious that she was still running a temperature.  Fifteen minutes later, she threw the blankets off while complaining that it was now too warm. I had recently taken our coat off, in addition to I didn’t notice a large difference, but I did notice that I was now deliciously warm.  I moved over by the window, where her bed was, in addition to I could believe the heat of the sun coming through the window. I could believe the heat coming off the heater. It was so sizzling in addition to dry that it made our eyes water.  Now I could understand why it was so for her. Two minutes later, the gas furnace turned off in addition to there was a cool air that was coming from the heater. You could believe the Winter cold coming off the windows. I immediately lowered the blinds in addition to closed the curtains.  My acquaintance wanted to see the outside, however the cold coming from the gas furnace in addition to off the windows, was outrageous. Two minutes later, the gas furnace turned back on, only to make the room too sizzling again. She told me that there had been a problem with the gas furnace since she came.  Even though she had said something to the doctors, so far, nothing had been done to rectify the gas furnace problem.
