Waiting for hot water in bathrooms far from the water heater wastes 2 gallons of water each time, multiple times a day.
Existing solutions (recirc pump, secondary water heater) are difficult to install due to concrete floor and crawl space access, and may not be efficient or cost-effective.

- Smart recirculation valve that uses cold water pipe as return line
- Compact 2-3 GPM tankless electric heater for immediate hot water
- Wi-Fi enabled scheduling and temperature control
- Easy DIY installation with standard plumbing connections
- Energy-efficient with low standby heat loss
Target Users: Homeowners with long hot water pipe runs, especially in slab-foundation homes, looking to reduce water waste and waiting time.
Revenue Model: $299 one-time purchase for the unit, plus $5/month subscription for smart features and usage analytics.
