What Size Water Heater Do I Need?
Several important factors, such as the number of bathrooms, daily hot water usage patterns, and appliance demand, help determine the best size for your water heater. For tankless systems, we also calculate your household’s flow rate (gallons per minute) and the necessary temperature rise to recommend the right unit. Here’s a general guide for sizing:
Traditional Water Heaters
- 1–2 people: 23–35 gallons
- 2–3 people: 36–45 gallons
- 4–5 people: 46–55 gallons
- 5+ people: 56+ gallons
Tankless Water Heaters

- 5 GPM for 2–3 fixtures at once
- 7 GPM for 3–4 fixtures at once
