If you have ever considered purchasing a propane furnace for your house, or if you have ever considered using a propane-burning primary heating system, then I want to tell you that this should be something that is to be avoided. Propane heating systems are very nice for only a couple of reasons. First of all, if you have a propane heating system, this means that your heating system is completely independent of the electrical system. Propane heating systems also are great for use in emergency situations, and these styles of heating systems are very portable. However, there are many more problems with a propane heating system that you should be aware of, and it is my opinion that you should avoid propane heating systems at all costs. First of all, propane heating systems are much more expensive than regular heating systems. This is because the propane that your heating systems rely on is very expensive. You will end up spending a lot of money on your heating system should you choose to purchase this heating system. Also, propane presents another trouble. Propane usually comes in smaller containers, which means that you will need to fill your propane tanks one a week. The trouble is that propane tanks are hard to gauge. There have been many times that I ran out of propane in the middle of the night, and I had no furnace. A few times, I had to drive to the gas station to buy a small propane tank to heat my house. This is not very convenient at all.
