For propane gas in Madison, area residents who rely on this fuel for home heating have a range of choices for types of delivery service. Most sign an annual contract with a supplier for keep-full service. The company delivers fuel when it is convenient for their routing schedule, topping off the tank about once a month. The customer doesn’t have to monitor the tank gauge. Some individuals, however, prefer to or must call for delivery as needed. They may prefer having control over the delivery times, or they may be on a very tight budget that doesn’t allow them to pay for monthly liquid propane deliveries.

These customers have to keep an eye on the gauge, especially during the coldest days of the year when the furnace uses more propane gas in Madison than usual. Delivery companies such as East River Energy generally recommend calling for additional fuel before the gauge drops to the 30-percent level. There are a couple of reasons for this recommendation. First, the customer may be able to afford to have the tank filled if it’s not almost empty instead of getting a minimum number of gallons. Companies usually offer a price break per gallon for a larger number of gallons. Second, the percentage of fuel in the tank can drop rapidly when the weather becomes bitterly cold. If the customer forgets to check the gauge and the propane gas runs out, emergency service is needed. An additional fee is charged, and the driver must come inside and make sure the system is working properly.

Although 30 percent is the benchmark, the definitive number is around 10 percent. With a 500-gallon tank, for example, the customer now has 50 gallons left. Dropping much further below that level can cause pressure issues and the furnace may not function efficiently. There is a significant risk of running out of fuel. The company may not be able to fit the customer into the routing schedule without scheduling special delivery for an additional fee. Although it’s best to call when the gauge reads 30 percent or higher, it’s crucial not to wait until the needle dips under 10.
