What size water heater do I need for my home?

For a standard home in Illinois, a 40-gallon tank handles 1–3 people comfortably, 50 gallons handles 3–4, and 75–80 gallons is right for larger families.

Tankless sizing is based on flow rate demand rather than gallons — how many simultaneous hot water uses you have at peak times. Quincy's cold groundwater temperatures in winter also affect sizing for tankless units.

Vinson and Sill sizes every installation correctly for your household — not just whatever's in stock.
