Tankless or "demand" water heaters are a useful energy efficient alternative to having a tank water heater. It is a smart alternative because it heats up the water as the sink, shower, or other hot/cold water using device needs it instead of having to fill up the whole hot water tank which saves you a load of money.
A tankless water heater is much more efficient as it "flash" heats the water.
It depends on usage.
Take shorter showers, or get a tankless, "on-demand" water heater that heats the water as you use it.
Tankless water heaters only heat water on demand, rather than storing hot water. They save money and energy while still providing quick hot water and are easily repaired. A tankless water heater will pay for itself in savings within one to five years.

it puts cold water in and pushes hot water to the top
It is not the square feet that determines the size water heater you need it is the demand. The more people who live in the home the higher the demand on the water heater to produce enough hot water. 1-3 people requires a 40 gallon water heater 4-6 people requires a 50 gallon water heater Of course you can make do with a 40 gallon water heater with a family of 4 or more but you will at times run out of hot water. Even if there are only 1 or 2 living in the home do not buy a 30 gallon water heater. You save very little money and may run out of hot water. But at least a 40 gallon.
At current gas prices they cost less to use and a gas heater gives you a much greater supply of hot water on demand.
The purpose of advertising is to increase consumer demand
The purpose of a heater is to heat up the room when it is cold; by using gas
