The right size depends on your household’s hot water usage patterns, not just the number of people living there. A family of four with teenagers who take long showers needs different capacity than empty nesters who primarily use hot water for dishes and laundry.
We typically recommend 40-gallon tanks for 1-2 people, 50-gallon tanks for 3-4 people, and 75-80 gallon tanks for larger families or homes with high usage. However, if you’re considering a tankless system, sizing works differently—we calculate based on simultaneous usage and flow rate requirements.
During our assessment, we look at your current usage patterns, peak demand times, and any planned changes to your household. This ensures you get a system that meets your needs without paying for unnecessary capacity or running short during high-demand periods.
