Recommended Tank Size vs Number of Occupants

Formula

## Water Heater Sizing **Daily Demand = Occupants x Gallons per Person** **BTU/hr = Demand x 8.33 x Temp Rise / Recovery Hours** The constant 8.33 is the weight of one gallon of water in pounds. Tank size is rounded up to the nearest standard 10-gallon increment.

Exemplo Resolvido

A household of 4 using 20 gallons each, 70 degF rise, 1-hour recovery.

  1. 01Daily demand = 4 x 20 = 80 gal
  2. 02Tank size = round up to 80 gal
  3. 03BTU = 80 x 8.33 x 70 / 1 = 46,648 BTU/hr

Perguntas Frequentes

What temperature rise should I use?

In most regions, incoming water is 50 to 60 degF and the target is 120 degF, giving a rise of 60 to 70 degF. Use 70 degF as a safe default.

Tank vs tankless - how does sizing differ?

Tankless heaters are sized by flow rate (GPM) and temperature rise. This calculator is for tank-style heaters where storage capacity is the key variable.
