Water Quality Comparison Analysis
Executive Summary: Sector GY1 6 vs Sector SW1A 1
Comparing tap water mineral concentration between Sector GY1 6 (Guernsey Water) and Sector SW1A 1 (Thames Water) reveals a water hardness difference of 135 PPM. Sector GY1 6 has softer water at 140 PPM (Slightly Hard) compared to Sector SW1A 1 at 275 PPM (Hard).
Limescale risk and boiler heating efficiency vary based on these mineral levels. Households in Sector SW1A 1 experience higher heating element degradation and kettle scale accumulation due to elevated calcium carbonate density (275 PPM vs 140 PPM).
For home appliance setup, Bosch dishwasher water softener settings should be calibrated accordingly: Sector GY1 6 requires setting H01 whereas Sector SW1A 1 recommends setting H04.
