Whoever set up my house neglected the insulation. The whole area is hardly airtight. The windows were awkwardly placed and caulked around. You can detect the cold air leaking through them all Winter. The doors all were placed just a bit too high off the ground. The air can breeze through right underneath them. The worst is that whoever did the insulation for the walls is bad at their job. They must have botched the measuring job or did not have enough materials. It would seem the contractor only put insulation up to the baseboards. He then just put wood over that lowest part of the wall. There is clearly no insulation down there, it is freezing that low to the ground. Since my home is not sufficiently insulated, heating is a problem. The living room uses a gas fireplace to give us heating. Even with the fireplace on all day everyday, it is barely enough. Right next door in the kitchen, there is another little gas heater system. The two of them need to work together to make these two rooms warm. This does not mean they are powerful enough to heat the upstairs floor though. I had to buy a seperate gas heater for that. In the Winter, my family needs to leave their doors open. It is necessary to get access to that upstairs heater. If we shut down the heaters for more than half an hour, the house temperature can drop fast. I really should invest the cash in insulation and sealing the house rather than more heating.
