A heater can easily increase the room temperature by 10-25 degrees Fahrenheit. Modern heaters are safe, you needn't worry about fire and very quiet. Freestanding heaters are tall and resemble a lamppost with an umbrella type housing on top. This helps radiate heat downwards. Some models now come with wheels, which facilitate moving your heater from one place to another while some even come with carrying cases. When it's not in use, you can put the heater in its carry case, or under an appropriate cover, and just wheel it away!
