FAQ
🚰Is a 80-gallon capacity gas water heater enough?
The “draw efficiency” of both electric or gas units is generally calculated at approximately 70% of the overall tank storage size.
This is because as a tank is being emptied of hot water, it is also being filled with cold water, so approximately 70% of it is usable hot water.
This means that an 80-gallon unit has a draw efficiency of around 56 gallons.
This is enough to simultaneously maintain four baths running or three baths with an automatic clothes washer running.
💧How long does it take an 80-gallon capacity gas hot water heater to heat up?
There are a few different factors that come into play when talking about this, including the type (gas or electric), the heating element inside the tank, and the temperature of the water that is entering the unit.
However, hot water heaters will have two ratings that will help you determine the answer to this question, and these are:
First Hour Rating: The total amount of water in gallons that the heater can supply per hour, starting with a full tank of hot water.
Recovery Rate: The total amount of water in gallons that the heater can supply per hour, starting with an empty tank.
🚰80 gallon gas water heater cost
These units vary in price, ranging from around $1000 through to $4000.
As we mentioned at the beginning of the article, we have listed the water heaters in order of cost, from the lowest price at the top ($) to the largest price ($$$$$) at the bottom.
