<human>:  How should I keep my house warm during the winter?
<bot>: The best way to keep your house warm during the winter is to make sure your home is properly insulated and that all doors and windows are sealed tightly. You should also consider installing a programmable thermostat and setting it to a comfortable temperature. Additionally, you can use space heaters to heat specific areas of your home, as well as use heavy curtains to further insulate your windows.
