Standard steel oil tanks feature a top feed intake pipe and vent pipe that go outside. These allow for the drive to delivery oil through the intake pipe, while hearing for a whistling noise from the vent pipe to know when the tank is full. The oil that is stored in the tank is feed to the heating system through the bottom of the tank where it is filtered and sent through a copper line. Through the vent pipe, changes in temperature, and time allow for condensation to form inside the tank. This can lead to corrosion and over time leaks and failures. Check out our tank protection page for things you can do eliminate risk from leaks.
Roth tanks just like their steel counterparts are top feed to the intake pipe and vent pipes from outside to inside the home. One of the major differences is that the oil from the tank to the heating system is also pulled from the top. This helps to remove sediment from collecting in the filter, reducing the risk of clogs along the pipe. Roth tanks as mentioned are double walled with an inner polyethylene tank and a galvanized steel outside tank.
Oil tanks whether they are a Steel Tank or a Roth Tank are most often found in the basement or close to your heating system. This different than propane tanks that must stay outside or natural gas that piped into the house from the street. Oil tanks in the basement should be in the same room as the heating system to allow for an optimal flow of oil from the tank to the heating system. Oil lines are made of copper and are required by state law to be covered by a plastic coating, usually orange. This coating prevents against the copper piping corroding over time.
Oil tanks should always be freestanding and should remain clear of debris. If your oil tank cannot stand on its own then you should consider replacing it as soon as possible.
Oil tanks that are outside need to be better protected than their inside counterparts. First, you should make sure that your oil tank is set on a concrete pad. This ensures that your oil tank stays level and is not susceptible to influxes in the condition of the soil. Next, you need to be mindful of snow and ice falling onto your tank. You need to have something that covers the oil filter and attachments for the oil line out of the tank. Roth tanks have an easy attachment that goes on the top of the tank that looks similar to a roof or a tent. Lastly, you should ensure that your oil tank is anchored to your home. While oil tanks are relatively heavy it a good safety practice to make sure your tank canâ€™t tip over and spill.
