Oil Tank Service

Oil tanks require servicing to remove water and sludge. DCR specialise in oil tank servicing, ensuring your tank remains in optimal condition throughout the year.

How does water get into my oil tank?

Oil tanks are not sealed units, this is a common misconception.  Faulty seals, damaged vents, splits to the tank body and in many instances leaving the lid off will result in water contamination within your oil tank. Rain water can enter the tank though any of these methods, however more often than not, condensation is to blame. Over a long period of time the water can accumulate and enter the fuel line to your boiler which can cause damage to the burner components, affecting combustion. The water in the fuel line is also in danger of freezing in the winter months preventing fuel from reaching the boiler and risking a split fuel line.

Booking an annual inspection from a DCR qualified heating engineer will ensure your tank remains in good condition and performs optimally in adverse conditions.

 Polite friendly and couldn’t do enough

Can’t recommend this company highly enough. Lewis, Paddy and other staff worked tirelessly over the Christmas weekend to change us over from solid fuel to oil. They were here early and left late at night. 
Lovely guys who were polite friendly and couldn’t do enough for you.

Thank you very much, an excellent job done. All the guys were extremely polite and explained what they were doing. Action was swift when we thought the old oil tank was going to burst. I would recommend this company whole heartedly.
