Similar to having a gas boiler regularly serviced both OFTEC and oil boiler manufactures also recommend a yearly service to keep your oil boiler working at its most efficient. An annual oil boiler service helps to reduce fuel bills and save money on costly breakdowns. Total Energy Services have been servicing and maintaining oil boilers for domestic and commercial customers for over 25 years across Dorset, Somerset, Wiltshire and Hampshire. By having your oil boiler serviced regularly by an OFTEC technician you can afford the peace of mind that you are doing all you can to keep your boiler working at its most efficient level.
