The number, in real terms
At 114 mg/L (6.7 grains per gallon), a four-person Lucan Biddulph household puts only about 2,000 grains of hardness a day through its plumbing (industry sizing convention: about 300 US gallons a day). That is a light enough load that most homes skip the softener and just descale the kettle now and then.
Scale ceiling: every 1,000 litres heated can leave at most 114 grams of scale, because that is the total mineral carried at 114 mg/L. Real kettles and water heaters precipitate a fraction of that, but the ceiling scales with the number: Lucan Biddulph's moderately hard water leaves little behind.
How this is calculated: grains per gallon = mg/L divided by 17.1; daily grain load = gpg x 300 US gallons (the softener trade sizes in US gallons, four-person household); regeneration interval = 32,000 grains divided by the daily load; scale ceiling = mg/L carried per 1,000 L. The input figure is Huron Elgin Water - Consumer Resources FAQ's own published number, checked 2026-07-03. Full method on the methodology page.
