Water Quality Comparison Analysis
Executive Summary: Sector GU3 3 vs Sector SW1A 1
Comparing tap water mineral concentration between Sector GU3 3 (Thames Water) and Sector SW1A 1 (Thames Water) reveals a water hardness difference of 5 PPM. Sector SW1A 1 has softer water at 275 PPM (Hard) compared to Sector GU3 3 at 280 PPM (Very Hard).
Limescale risk and boiler heating efficiency vary based on these mineral levels. Households in Sector GU3 3 experience higher heating element degradation and kettle scale accumulation due to elevated calcium carbonate density (280 PPM vs 275 PPM).
For home appliance setup, Bosch dishwasher water softener settings should be calibrated accordingly: Sector GU3 3 requires setting H05 whereas Sector SW1A 1 recommends setting H04.
