## What is Cold Radiator Fix · LockShield?

Stop wasting money on unbalanced heating! Lockshield guides you step-by-step to balance your radiators using just a simple thermometer. A balanced heating system ensures even heat distribution, silences noisy radiator pipes, and reduces your heating bill by up to 15%.

Why balance your radiators?
In an unbalanced system, hot water takes the path of least resistance. Radiators closest to the boiler or heat pump get too hot, while rooms further away remain cold. Lockshield calculates the exact physical valve adjustments needed to distribute heat evenly.

Features:
- Step-by-step setup wizard
- Automated Delta T calculation based on your boiler or heat pump type
- Intelligent non-linear valve curve adjustments
- Stabilization timers for precise measurements
- Professional PDF report generation
- Works 100% offline with complete privacy
