<human>:  What can I do to keep my house warm in winter on a budget?
<bot>: To keep your house warm in winter on a budget, you can try sealing drafts and insulating windows, minimizing the number of doors left open, and using space heaters to target specific areas of the home that need extra warmth. Additionally, you can use heavy window treatments to keep cold air out, lower the thermostat to a comfortable temperature, and utilize additional floor coverings like area rugs to absorb cold air and create a warmer atmosphere.
