Storage tank water heaters are the most common type and the best water heater to buy. These units have an insulated tank where water is heated and stored until it is needed. They are available in electric, liquid propane (LP) and natural gas models. Natural gas and LP water heaters normally use less energy and are less expensive to operate than electric models of the same size.
Storage tank water heaters are designated by the amount of water they hold, in gallons. Tank size is one of the major considerations when purchasing one of these water heaters. If you intend to use a storage tank water heater, use our chart as a guide to finding the size you need.
Another consideration for storage tank water heaters is recovery rate â ” the number of gallons of water they can heat in an hour. The greater your demand for hot water, the higher recovery rate you need.
When you buy a water heater, look at the energy efficiency and yearly operating costs of a water heater before you decide which one is right for your needs. This information can be found on the EnergyGuide label.
Know the dimensions of the space where your water heater resides. If your hot water use increases and you need to upgrade to a larger tank size, it may be necessary to run plumbing to a different area so the new, larger unit will fit. One alternative to running new plumbing is to purchase a low boy or shorty water heater. These units are shorter and bigger around than a normal water heater, allowing them to hold the same amount of water as their larger counterparts while still fitting in areas with limited headroom.
Small storage tank water heaters, known as point of use, utility or mobile home water heaters, are good choices for adding hot water to out buildings, shops or garages. Utility water heaters usually range in size from 2.5 to 19 gallons. The largest of these miniature units can also be used to provide hot water to secondary bathrooms that may be situated far from your home's main water heater.
Tankless water heaters heat water as you need it.
Tankless or on-demand water heaters do not store hot water; rather they heat water as it passes through a series of coils in the unit. Since the unit only heats water as you use it, a tankless heater is usually more energy efficient than a traditional storage tank water heater. They are available in electric, LP and natural gas models. A tankless unit can provide an unlimited amount of hot water, but it can only provide a limited volume. Most tankless units can provide up to 3.5 gallons of heated water per minute. These units are a good choice for anyone whose demand doesn't typically call for hot water at more than two points at a time.
Hot water dispensers are great for making instant coffee or hot tea.
Hot water dispensers are convenient point of use water heaters. They are great for making soups, sauces, oatmeal and other instant foods. These units provide 190° water instantly, so be careful when using them.
Why, the materials used to make them are better. Depending on which one you get they a warrantied for 15 years.
