## Summary

Guardian reporter Samuel Gibbs says AI-controlled Tado heating used 11,735.7 kWh of gas over 213 days from November to May, 2,581 kWh less than his manual control in the same period. He says the household was also more comfortable. The Tado X system with AI features costs about £930 plus about £80 for boiler wiring, plus a £3.99 monthly or £29.99 yearly subscription.
