Household Hot Water Needs:
To make a reasonable approximation of your household hot water needs, you have to select between two methods. One method is for households with tankless water heaters and the other is for households with hot storage tank style water household heaters.
Know consumptions of gallons per minute rating (GPM) make a list of all the ways hot water is used in the house. That means showers, baths, whirlpool tube, clothes washing, hand dishwashing, dishwashing machine, shaving hand washing. Try to make a reasonable estimate of the most extensive hot water use that happens in the household. Let's say there are two showers going at the same time the dishwashing machine and the clothes washing machine are on. That would be four full use hot water activities all at once.

It runs on natural gas, so internal burners and heat exchangers fire up whenever cold water is detected in the pipes. The T-H3-DV-N works with a condensing system.
