Propane is a very popular fuel for all sorts of home heating. Propane water heaters, furnaces, and boilers are both very common in residential properties. Propane is a widely available fuel that is popular due to the fact that it burns very efficiently. You can find propane furnaces that burn at 97% efficiency. That is, they have an AFUE (annual fuel utilization efficiency) of 97%. This standardized measurement is used to compare natural gases, propane, and heating oils. Propane is usually the most efficient of these options.
There are many different ways that you can have your propane refilled or delivered. Most modern propane tanks are fitted with a sensor that can automatically tell you when you fuel levels are low. However, it is even more convenient if you have a tank that automatically informs your propane supplier that you levels are low. This way, they will be able to come to your home and deliver the fuel without the building owner even knowing anything about. This is extremely convenient. Surprisingly, some people still only have their levels refilled on a schedule. For instance, they could have their delivery come every March. The only drawback to a set schedule is that there is a good chance that you use all of your fuel before the delivery arrives. This is common if there happens to be a cold winter where you are using your water and air heaters more frequently.
You can also opt for request only refills. That is, your propane will only be delivered if you call. This means you need to keep an eye on your levels and schedule refills before you run out. This set up is not great if you aren't vigilant and good at keeping an eye on your home propane levels. However, propane supply companies can offer great flexibility for homeowners in small homes that don't need refills too often.
Your payment plan is largely dependent on your refill schedule. However, in order to get the best value for your money, you want to minimize actual service calls and deliveries. That is, a large portion of your overall propane supply costs can come from the services fees, rather than the actual propane. Keep this in mind when planning how often you are going to order refills and deliveries.
Regardless, propane is a great fuel for heating the water or air (or both) in your home.
