Hot water recovery takes 40 minutes after a small draw, due to boiler's factory-limited 60°C max flow temperature for hot water, causing the house to cool down in winter.
The boiler's firmware caps the hot water flow temperature at 60°C, preventing the user from increasing it to speed up recovery. The app provides monitoring but no control over this parameter.

App Concept
HotFlow Tune
A software tool or device that overrides the boiler's factory-set hot water flow temperature limit, allowing users to set up to 75°C for faster recovery. Integrated with smart controls and cylinder thermostat for safe operation.
Key Features
- Overrides factory-limited HW flow temperature up to 75°C
- Smart scheduling to prioritize hot water during recovery
- Real-time monitoring with recovery time estimation
- Safety auto-shutdown if cylinder exceeds 60°C
Target Users: Homeowners with Worcester Bosch 4000 system boilers and unvented hot water cylinders who are frustrated by slow hot water recovery.
Revenue Model: $49 one-time license fee for the software unlock, or $99 for a hardware dongle
