Usually about an hour.


How long will it take a 40 gallon water heater to heat up?

"One hour for a new water heater" for a NEW one. If its a few years old, Id wait about 2 hours or so. That way it wont get cold while you are in the shower, and it can refill at the same time that it dispenses.

If you put a five pound fish in a gallon of water does the water now weigh fifteen pounds?

A gallon of water weighs about 8.34 pounds. If you have a good sized bucket with a gallon of water in it and you put a 5-pound fish in the bucket, you'll have a bucket that weighs about 13.34 pounds (plus the weight of the bucket). That's as long as the bucket doesn't overflow. The fish will (usually) be neutrally bouyant in the water, and it will be essentially weightless in that water. But its weight will add to that of the water in the bucket. No, it won't weigh 15 pounds, but it will weigh in as suggested. However, the weight of the water itself will not change.

How many gallons of hot water should you get from a 80 gallon hot water heater?

About 60 gallons , if it is new. This amount will diminish over time because of sediment build up and corrosion. And while using hot water continuously the temperature of the water will decrease as you reach the water heater capacity because it is mixing cold water with the already heated water to replenish what is lost. Thus, the modern age of tankless water heaters. If sized, installed properly you can run hot water at an exact temperature for as long as you want. Fill a tub, still have hot water, in fact, fill a pool, and still have hot water.
