Your choice of tent heater should always be based on your needs. If you think that on your camping nights you have confronted with frigidity, then you should always opt for heaters with higher BTU. In case you want to sacrifice the BTU level and want something smaller in size, there are plenty of tent warmers available in the market. You have the options like battery-powered and propane-powered tent heaters as well. You can choose any product from the market as per your convenience. However, buy only those products that have standard safety features.
