What Should I Do about an Old Heating System?
Oilheat systems typically last 30 years or even longer. However, the older the system is, the greater the gain in efficiency and cleanliness you will achieve when you invest in an upgrade.
Keep in mind that an old oilheat system is no different than any other outdated heating system, regardless of the fuel used. Old systems can generate higher-than-necessary fuel bills, but they can easily be replaced with equipment that incorporates new oilheat technology.
The nonprofit Consumer Energy Council of America concluded that changing fuel sources does not make economic sense and a better investment would be to upgrade an older system to new oilheat equipment to improve efficiency.
