Can water in my tank damage my boiler?

Yes. Water and sludge reaching the burner can cause serious and expensive damage to boiler components. Addressing the tank is far more cost-effective than dealing with boiler repairs downstream.

Do you dispose of the contaminated oil?

Yes — we remove all contaminated oil from site and dispose of it responsibly and in full compliance with environmental regulations. Paul holds a Waste Carriers Licence covering this as part of the service.

How do I know if there is water in my tank?

Common signs include frequent filter blockages, heating faults, and discoloured fuel. A professional inspection will confirm the presence and extent of any contamination.

What types of tank do you work on?

All types — plastic, steel, single-skin, bunded, above-ground, and underground tanks. We have experience with all major brands including Harlequin, Kingspan, Titan, and Carbery.

Do you offer emergency call-out?

Yes — if you are experiencing an urgent heating failure that you suspect is linked to tank contamination, call Paul directly on 07855 240198.

Is this a one-off service or do I need it regularly?

It depends on the age, type, and condition of your tank. Paul will advise on the appropriate frequency during the service visit.

Water Removal from Oil Tanks Sheffield

Contaminated Oil Removed, Tanks Cleaned and Back in Service — OFTEC Registered Engineer Across Sheffield, Rotherham & the Peak District

Water in a heating oil tank is one of the most common — and most damaging — problems affecting oil-fired heating systems. Left untreated, it causes corrosion, promotes bacterial growth, clogs filters and burner nozzles, and can lead to costly boiler breakdowns.

Omni Gas provides a full water removal and tank decontamination service across Sheffield, Rotherham, Chesterfield, Buxton, and the Peak District — draining the tank, removing all contaminated oil from site, and disposing of it in full compliance with environmental regulations. Paul is OFTEC registered and holds a Waste Carriers Licence, so the entire job is handled correctly from start to finish.

How Does Water Get Into an Oil Tank?

Water contamination can enter a tank in several ways:

Condensation forming inside poorly sealed or ageing tanks
Rainwater ingress through damaged lids, vents, or fittings
Delivery of contaminated fuel
Groundwater infiltration in partially buried or bunded tanks

Even small amounts of water sitting at the bottom of a tank can cause significant damage over time — accelerating internal corrosion and creating ideal conditions for microbial growth (sometimes called diesel bug).

Signs You May Have Water in Your Tank

Boiler cutting out or failing to fire
Filters requiring unusually frequent replacement
Dark, cloudy, or discoloured oil
Sludge or sediment visible in the tank
Unexplained or recurring heating system faults

If you are experiencing any of these issues, it is worth having your tank professionally inspected before assuming the problem lies elsewhere in your heating system.
