How to Buy a Gas Water Heater

Most homeowners probably do not think twice about something like a water heater until they experience a surge of cold water during their hot shower. Water heaters are a luxury standard in most U.S. homes. The most common kinds of water heaters are gas and electric. Gas water heaters are cheaper and more energy efficient than electric. There are two types of gas water heaters: a storage tank water heater that heats and stores the hot water and a tankless water heater that heats the water as you use it. There are a few things you should remember when shopping for a gas water heater.
