Water heaters work by using either gas or electricity to heat a tank full of water that is then distributed to taps throughout the house. A thermostat on the outside of the water heater allows the user to adjust the temperature of the water in the heater.
A fast water heater, sometimes called a tankless water heater, heats water on demand as it flows through the unit instead of maintaining a reservoir of water at temperature. These heaters can be more efficient than conventional water heaters, but can be expensive and may provide inconsistent tempera
As of 2015, the top three water heaters are the Whirlpool N40S61-403, the Rheem Fury 22V40F1 and the Ecosmart ECO 27, according to consumersearch.com. The Whirlpool and Rheem models both have a 40-gallon capacity.
The price of water heaters vary depending on the type of water heater, capacity and fuel source. The two basic types include storage tank or tankless, and a gas storage tank water heater costs between $230 and $2,000. An electric storage tank costs between $400 and $3,000 for complete installation.
There are two major types of water heater, those with a tank and those without a tank. Storage-tank heaters may be powered by gas, electric or solar energy, while tankless models use gas or electric. In addition, water heaters may be tied into a heat-pump heating and cooling system.
The water heaters at Lowe's range in price from $159 for a tankless water heater from AquaPower to $5,879.75 for a 100-gallon natural gas water heater from American Water Heater Company, as of early 2015. Lowe's also offers installation of the water heater for a small fee.
Water heaters are commonly measured by the volume of water they're capable of holding. In the United States this is based on gallons, while the measurement is given in liters in other parts of the world.
After removing and draining the old water heater, hooking up new flex pipe segments, connecting to the gas supply (unless the heater is electric) and linking to the water supply complete replacement of a hot water heater. Because of the heavy lifting involved, it is wise to enlist an assistant.
Electric water heaters use electricity to heat water. They do this primarily by way of an immersion heating element that can heat the water to a temperature adjustable by the user.
Heating elements are used in an electric water heater to convert electrical energy into heat and transfer it to the water. Since elements come in direct contact with water, they must be insulated well.
