The Tank Sponge Eco is designed to remove contaminated water from vented oil tanks which are prone to water collection at the base of the tank, specifically from condensation and atmospheric moisture. The device consists of a specially moulded cage made from 100% recycled plastic with a cotton absorbent sock and is packaged in 100% recycled cardboard.
The cage is hinged and designed to hold replaceable Tank Sponge Eco inserts, each of which will soak up to 700ml of contaminated water from the bottom of the oil tank, whilst not soaking up any of the Kerosene, Gas Oil or DERV.
Each cage is tested to be used more than 1,000 times, but should your cage get damaged in anyway, our Lifetime Guarantee means that we will replace it, for free – whatever the problem.
Installation of a Tank Sponge Eco is simple and can be used most standard domestic Heating Oil tanks.
