Oil central heating systems are a serious alternative to other types of central heating systems due to the wide availability, efficiency and affordability of oil. Furthermore when you fill up your tanks you know the price of the oil and won’t be surprised by high energy bills at the end of the year. Oil fired boilers are particularly popular heating options in parts of the country that have little to no access to natural gas. They are also as quiet, clean and efficient as other types of boilers and can be installed outside if necessary when space in the home is limited. All work carried out on oil boilers, from installation to maintenance to repairs, must be by an Oil Firing Technical Association (OFTEC) registered technician.
