Water Heater Installation Near me
Tankless water heaters use the same principles as tank type water heaters, except without a tank. With tank type water heaters, the water gets heated to a specific temperature and then kept at that temperature. A tankless water heater only heats water when there’s a demand, like when a faucet is turned on. When a hot water tap is turned on in the home, cold water is drawn into the water heater. A flow sensor activates the gas burner, which warms the heat exchanger. Incoming cold water surrounds the heat exchanger and leaves the heater at the temperature set by the user. Combustion gases safely exit through a dedicated, sealed vent system. A tankless water heater can be much more efficient by only heating water when there’s a demand, instead of constantly working to heat a tank of water.
Gas water heaters heat water by burning natural gas. Gas water heaters need a source of air and also need to be vented properly. Cold water enters the water heater through an internal “dip tube” which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection. This arrangement provides the most hot water for a given tank size. When cold water enters the tank, the temperature sensor on the gas control tells the main gas valve to open. Gas flows to the burner where it is lit by the pilot light. The air needed by the burner is supplied by the room where the water heater is installed. The exhaust gases are vented to the outside. When the proper temperature is reached, the main gas valve shuts off.

This arrangement provides the most hot water for a given tank size. There are typically two thermostats on a water heater. The top thermostat controls the top heating element and the bottom thermostat controls the bottom heating element. The lower element sees the cold water first, so it does most of the work, while the upper heating element is used only when the entire tank is cold. Water heaters should be large enough to provide adequate hot water even when temperatures are cold and household demand is greatest, so it’s important to choose an appropriately sized water heater.
