## Summary

A Guardian journalist spent two years testing whether AI-powered smart heating could reduce energy costs compared to manual control. The test took place in a 1930s brick house, comparing a basic Hive thermostat with a full Tado X system featuring 13 smart radiator thermostats and AI-driven automation.

During the winter of 2024, manual control with a basic schedule consumed 14,316.7 kWh of gas over 213 days. After switching to the Tado X system in summer 2025, which uses AI to learn room heating patterns and manage individual radiators, gas usage dropped to 11,735.7 kWh over the same period in 2025-2026. This represented an 18% reduction in energy use, equating to a saving of £205.70 at the current energy price cap.

The Tado system costs about £930 for the full setup, plus a £3.99 monthly subscription for AI features. The AI, built on data from over 1 million homes, automatically adjusts heating based on occupancy and window status. The tester noted that while the house felt warmer and more comfortable, the AI system was significantly more efficient than their previous "miserly" manual approach, suggesting greater savings are possible for less frugal users.
