My wife and I used to go camping all of the time, even when the weather outside was very cold and chilly.
We had a tent for a long time, so we always kept a space heater in the camping supplies.
When my wife and I moved from a tent to an RV, we put the space heater in the garage. It has been sitting on the shelf in the garage for the past three years, but it still came right on when I needed to use it last weekend. The furnace stopped working in the middle of the night on Saturday and my wife and I did not want to pay the emergency fees to the heating company. It was pretty cold and the house, but I remembered the space heater and the garage. I brought it to the bedroom and closed our door. I turned on the space heater and we let the machine run all night long. We stayed very warm in the bedroom, even if the rest of that house was intensely cold.I called the heating company as soon as we woke up in the morning. My wife and I had a full breakfast with oatmeal, eggs, toast, and fruit. Shortly after we finished eating, the heating company technician showed up to work on the furnace. My wife and I did not have any inconvenience by waiting until the morning to have the repair handled, because we had the space heater in the garage. The $15 machine is 10 years old and it still works like a charm.
