Continue to use instead of decommissioning

Tank conversion

Convert old fuel oil tanks into modern rainwater storage tanks when replacing heating systems. Retrofit your old heating oil tank with AFRISO inner linings at low cost - your specialised company will be happy to advise you.

Sustainable re-use

If you are faced with the decision to replace your heating system, it is advisable to carefully scrutinise all options carefully and, in the interests of sustainability, also examine the potential re-use of existing system components.

For example, when decommissioning a heating oil storage tank, owners already invest in an essential step for conversion to a rainwater storage tank with the mandatory tank cleaning. So why not take the next step straight away and benefit from free rainwater for watering the garden, flushing the toilet, doing the laundry or cleaning?

Precious and scarce resource

Drinking water is a limited resource, and clean drinking water is more and more difficult to provide in many regions. The price of drinking water has increased by approx. 350 % since 1988. And the price is expected to continue to rise exponentially. On the other hand, expensive drinking water is still wasted in many situations. According to the German Association of Energy and Water Industries (BDEW), the daily water consumption of a person in Germany in 2019 was 125 litres*.

Depending on the system layout, up to 45 % and thus more than 55 litres of domestic drinking water consumption can be saved today using rainwater. The old fuel oil tank is the free basis for your customised rainwater harvesting system.

There are many good reasons for rainwater harvesting

Environmental consciousness and sustainability: Preserve the precious resource of drinking water by using rainwater for garden irrigation
Good for the plants: Rainwater is "soft" and free from minerals and, therefore, better suited for garden irrigation than drinking water
Reduction of waste: Re-use of the old tank instead of decommissioning or removal
Cost savings: "Split wastewater fees" of the municipalities and your storage and consumption of rainwater have an immediate positive effect on your wastewater fees
Investment in the future: The AFRISO inner lining and a submersible pump provide, for example, for cost-effective garden irrigation. The more rainwater you use, the faster your return on invest resulting from savings of expensive drinking water

Conversion – this is how easy it is

1.

The old fuel oil tank is drained, cleaned and corrosion-inspected by the specialised tank protection company.

2.

Depending on the condition of the tank, a fleece layer is placed on the tank floor, for example, for impact protection.

3.

Then the rainwater lining is fitted in the steel tank and inflated by means of a blower; if necessary, the final fit is achieved by means of a vacuum pump.

4.

During inflation, the magnets lock against the inner wall and then permanently hold the inner lining to the tank wall.

5.

The fit of the PVC lining is checked and then it is fastened in the manhole by means of a fastening ring.

6.

Done. The tank is ready for storing rainwater immediately after the piping connections have been installed.

The inner lining for rainwater AR-SM turns the old fuel oil tank into a modern rainwater storage tank

The AFRISO rainwater inner lining AR-SM with magnets allows owners to convert a decommissioned steel tank into a rainwater storage tank with very little effort. The inner lining for rainwater AR-SM is an extremely durable PVC lining with flat, round, extremely powerful neodymium magnets welded into lateral and top areas. The lining is reliably held at the inner wall by the magnets. Additional equipment such as vacuum type leak detectors, which are used in conventional solutions, are not required for the operation of this rainwater inner lining – which means there are no subsequent costs for power or maintenance.

No subsequent costs due to additional equipment or power: The magnets enable operation of the inner lining without pressure or power

Strong neodymium magnets welded into the film ensure fast installation and reliable fixation

Ideal for all standard, cylindrical steel tanks with a capacity from 3,000 to 50,000 litres

Custom-fit plastic inner lining, accurately factory-tailored to the specifications of your tank protection specialist company
