All tents aren’t created equal. The first thing you should do when picking a heater for your tent is to consider whether or not it has windows. If your tent does have windows, then you’ll want to make sure that whatever heater you choose doesn’t create additional condensation in your tent. The most common type of window-equipped tents are Dome Tents: These are great if you’re on a budget and need something basic but effective. Dome tents usually use two forms of ventilation; either two poles in between two layers of canvas that can be opened and closed, or an opening near each pole where air can flow freely out of your tent.
