How to Use the Heat Pump Water Heater Size Calculator

If you're looking for an efficient and cost-effective way to heat water, a heat pump water heater may be a great option for you. However, it can be challenging to determine the appropriate size of the heat pump water heater for your household. Fortunately, the Heat Pump Water Heater Size Calculator can help you determine the ideal tank size for your household's hot water needs.

Input Fields

To utilize the Heat Pump Water Heater Size Calculator, you must input six key factors:

  • Household size,
  • Usage type,
  • Temperature rise,
  • Average temperature,
  • Hot water usage, and
  • Desired tank size.

Household size refers to the number of individuals residing in the house. Usage type is the number of showers per day that the household will use. The temperature rise is the difference between the cold-water temperature and the desired hot water temperature. The average temperature refers to the average temperature of the incoming cold water. Hot water usage is the amount of hot water used daily in gallons. Finally, desired tank size refers to the desired size of the tank in gallons.

Output Fields

The output fields are straightforward and easy to understand. The calculator will display the household size, usage type, temperature rise, average temperature, hot water usage, and desired tank size that you inputted. It will also provide the recommended tank size based on the input data. The recommended tank size indicates the size of the tank that will accommodate your household's hot water needs efficiently.

Formula

The formula used by the Heat Pump Water Heater Size Calculator is relatively simple. It is based on the total hot water needed in gallons per day, divided by the available hot water storage in gallons.

  • Total Hot Water Needed (Gallons/Day) = (Household Size x Usage Type x Hot Water Usage) + (Temperature Rise x 0.75 x Household Size)
  • Available Hot Water Storage (Gallons) = Tank Size x 0.9
  • Recommended Tank Size (Gallons) = Total Hot Water Needed / Available Hot Water Storage

Example

To illustrate how the calculator works, let's consider an example. Suppose you have a household of four people who take three to four showers a day. You live in a location with an average temperature of 60 degrees Fahrenheit, and you want the hot water temperature to be 120 degrees Fahrenheit. Your hot water usage is about 100 gallons per day, and you want a tank size of 80 gallons. By inputting these values into the calculator, you will receive a recommended tank size of 100 gallons.

The following table provides an illustrative example of how the Heat Pump Water Heater Size Calculator can help you determine the appropriate tank size for your household based on various inputs.
