In This Article:

MIAMI, March 26, 2025 /PRNewswire/ -- Star8 Corp. (OTC: STRH), ("Star8" or the "Company"), through it's subsidiary TOMAHAWK SRL an Italian R&D and manufacturing company, specializing in EV, battery storage and electric motor innovations operating and also manufactures EV motorcycles under the brand Scarponi Motorcycles, is proud to announce that it has filed a patent application for a revolutionary Hot Water Heating System aptly named "ZeroTANK System".

ZeroTANK System

Unlike our Scarponi Motorcycles, the "ZeroTANK System" is aimed at the mass market. "Not everyone has the need for one of our Scarponi Motorcycles, but everyone has a need, and right to clean, hot water"…… Gianluca Scarponi, CEO/CTO

A New Era of Efficiency and Performance

The "ZeroTANK System"' (ZTS) produces hot water on demand, (zero tank or water storage) at a rate of 15 litres/per minute @ 40 degrees Celsius (3.96 gallons/per minute @ 104 degrees  Fahrenheit).

COMPARISON: 

ZERO TANK SYSTEM vs 120L TRADITIONAL BOILER

Characteristics

120L Traditional Boiler

ZeroTank System

Nominal Capacity

120 liters at 65°C

242 liters at 40°C

Mixed Water Output (at 40°C)

~240 liters

~242 liters (4 x 5-minute showers)

Power Rating

1.5 kW fixed

1.5 kW power  + 18 kW peak

Energy Required for 240L @ 40°C

~7 kWh

~0.5 kWh (0.5 kWh from the grid)

Heating Time

4–5 hours

20 minutes (on-demand)

Standby Losses

~1.2 kWh/day (~438 kWh/year)

~0.12 kWh/day (~43 kWh/year)

Estimated Annual Output

~1369 kWh

~2190 kWh (only during use)

Efficiency

Low (slow, with heat losses)

High (instant and direct heating)

Space Occupied

~216 liters of physical volume

~31 liters (−85% volume reduction)

Hygiene

Stagnant water → bacterial risk

Flow-through only → no stagnation

None

Wi-Fi, Bluetooth, Ethernet, App control

Additional Comfort Options

None

Air heater, RGB chromotherapy, speakers

Design

Standard cylindrical

Compact, wall-mounted, modern

Advantages

  • Elimination of standby heat losses due to the absence of a storage tank

  • Reduction in physical volume by over 85% compared to traditional systems with equivalent hot water output

  • Instantaneous and continuous delivery of hot water using stored electrical energy

  • Compatible with limited power grids through controlled recharging

  • Modular architecture suitable for residential, healthcare, and professional environments

Functional and Structural Characteristics

  • The system does not include a thermal storage tank: water is heated at the time of use via battery-stored energy.

  • The device supports local and remote connectivity using common communication protocols (Wi-Fi, Bluetooth, Ethernet, Zigbee, LTE, etc.).

  • It can be monitored and controlled remotely via mobile app or integrated into smart-home ecosystems.

  • Optionally, the unit can be equipped with an air-heating module to improve shower comfort.

  • It may also include optional RGB lighting systems for chromotherapy and integrated speakers for music or ambient sound playback.

  • All optional modules are software-managed and configurable via central control or remote interface.
