I know if you were to step outside right now you wouldn't suspect warmer days are in our near future, but they are. The days are longer, the sun is stronger and it won't be long before you receive your last oil delivery of this heating season. If you are a will call customer and you have under a half tank of oil, you may wonder whether it's a good idea to fill up before summer or wait until next fall. Historically, oil prices dropped in the summer and then rose again once the cold weather came around. That isn't necessarily what happens nowadays. There are many outside factors that affect oil prices, many more than years ago. Therefore, waiting until mid summer to save on oil isn't always a guaranteed strategy. When summer does eventually come around so will the humidity. The one place in our homes most affected by humidity is our basements. Home of our oil tanks! I have touched upon inspecting your oil tank in a pervious blog, but you can't always see where the steel is breaking down. Often times, the inside of the tank begins to corrode first, having a near empty tank during the summer will certainly speed up this process. Having exposed steel inside your tank, above your oil level will hold a lot of condensation. This condensation will begin to eat away at the steel. How do you combat this? Fill your tank. The less exposed steel inside the tank during the summer, the less condensation it will collect. To be fair, if you have more than 5/8 of a tank, I would not worry about condensation as much as if you only had 1/4 tank. Remember, Fitchburg, Leominster and Lunenburg we make deliveries as low as 100 gallons. Gardner, Ashby, Ashburnham, Townsend, Lancaster, Sterling we have a minimum order of 135 gallons.
