Prevent Water Accumulating In Your Oil Tank with a Tank Sponge

Our tank sponges absorb up to a litre of water from your oil tank. They are a cost effective way to prevent the accumulation of water before it can cause damage to your heating system.   

How Does Water Enter Your Tank?

How Does Water Enter Your Tank?

•    Condensation occurs naturally in all tanks and drips down into your fuel.
•    You may have a small leak in your tank.
•    Water can enter your tank when the cap was off.
•    Leaving the tank filler cap open can lead to a build-up of moisture.

What are the Negative Side Effects of Water in Your Tank?

•    If you have a metal tank, then there is a greater likelihood of rust within the tank.
•    In really cold conditions, the water layer can freeze inside your tank which can degrade your fuel.
•    Bacteria and sludge form inside your tank.
•    Water can be passed through the heating system instead of the heating oil which can damage your boiler / AGA.

How Does a Tank Sponge Work?

The driver pops it into the tank when delivering fuel.  The tank sponges have a string that the driver can attach to the outside of the tank so that they can be easily pulled up.  The granules inside the sponge only absorb water - not fuel. They can be disposed of in a plastic bag in regular black bag waste.


At just £19.99, a tank sponge is considerably cheaper then a tank clean to remove water from your fuel tank.
