Why water in your oil tank is bad news
A bit of water in your tank might not sound like a big deal, but it can cause all sorts of headaches, including:
- Tank damage: Water can eat away at metal tanks leading to rust, leaks, and even structural failure.
- Clogged filters: Water encourages bacteria and sludge growth which can block oil tank filters, damaging your heating system, and leading to costly repairs.
- Higher heating bills: Contaminated fuel makes your boiler work harder, which means less efficiency and more money spent on heating.
- Fuel degradation: In cold weather, water can freeze and reduce the quality of your oil, meaning you might need a pricey tank clean.
- Blocked fuel lines: If water freezes in your fuel, it can clog lines and stop your heating from working when you need it most.
TankSponge Eco is a simple, eco-friendly way to get rid of water, protect your fuel quality, and stop sludge from building up in your tank. It helps you steer clear of costly tank troubles and unexpected repairs. It’s our top tip for keeping your tank in great shape and your heating running smoothly for longer.
Cleaner fuel with less hassle
How does TankSponge Eco work?
TankSponge Eco is made up of a reusable cage (crafted from recycled plastic) and absorbent inserts that soak up 700ml of water without absorbing your heating oil. Just pop it into your tank, attach the string for easy removal, and check it once a quarter.
When the sponge is full, swap it out for a fresh one. That’s it. No mess, no stress — just reliable protection for your heating oil.
Made from sustainable materials, it’s the environmentally friendly choice to keep your heating in check while helping the planet, too
