Provide water, electricity and heat as budget and prepaid

Prepaid water and electricity for apartments

The modern and simple way to provide and bill flats for electricity, water, heat, and washing machines directly online via smartphone, securely and without administrative effort. With the networked prepaid meter, residents can top up credit as needed and draw water, electricity, and heat until the credit is consumed. The resident has an overview and control of their consumption at all times and there is no risk of non-payment.

Water and electricity quotas

The most technically advanced solution in real estate electricity, water, heat and equipment operating times without costly service charge billing and without the risk of additional claims as prepaid credit or budget. If the budget is exceeded, the user can easily and quickly add credit. A display in the apartment provides a simple overview of the current residual budget and previous consumption. This supports a more conscious use of resources.

Prepaid water in industry and irrigation

In many places, water tankers fulfil the essential task of supplying drinking water. Especially in remote areas, a tanker filling station with the prepaid meter simplifies the billing of large water customers. The filling stations are equipped with water meters and valves from 2 to 10 inches. These stations can be operated completely self-sufficiently or with personnel. The Prepaid Meter offers 24h access to water and better control.
