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.
One can find instructions for a 40 gallon water heater for installation from the 'American Water Heater' website where it can be viewed in PDF format. One can also find instructions on the 'About' website.
Tankless. A tankless heater heats the water as you use it. It doesn't store hot water and keep it hot day and night whether any is used or not. The water is heated almost instantaneously, and the heater will keep the hot water flowing as long as the water is turned on.
Regular insurance will not. If you just purchased the house and have warranty insurance and the water heater is listed it will.
