Water Heaters.

The water heater in your home, is connected to the cold water supply. Cold water enters the heater whenever a hot water faucet is opened somewhere in the system. As hot water is drawn out, normal water pressure refills the tank. Conventional water heaters store heated water in a cylindrical tank. Tankless, point of use water heaters are becoming popular because of their efficency. These heat water on demand and deliver it directly to faucets or an appliance.

Water heaters can be fueled by natural gas, propane or electric. A conventional gas water heater uses a burner beneath the tank. A thermostat detects the temperature of water in the tank and lights the burner to heat water when needed. Newer water heaters, use a spark ignition and older models use a pilot light. Toxic emissions from combustion are vented out the top and through a chimney.

Newer, high-efficiency water heaters provide a more complete combustion and may be vented to the exterior of the home using a fan-assisted vent.

An electric water heater uses heating elements and does not create any combustion gases so a vent can be avoided. Electric water heaters typically have one 5500-watt or two 4500-watt elements for faster heating. Separate thermostats control each element, cycling on as needed.

A tankless water heater circulates water through an array of electric coils or burners when there is a demand for hot water from a faucet or appliance. This is more economical to operate because water is heated as needed. Heated water is used and does not sit in a tank cooling off.

Every water heater has a thermostat that controls the temperature of the heated water. This thermostat must be carefully adjusted to ensure scalding water is not discharged from the tank. DO NOT ADJUST THE WATER HEATER THERMOSTAT WITHOUT TESTING THE TEMPERATURE. AFTER ANY ADJUSTMENT, THE TEMPERATURE MUST BE MEASURED AT THE FAUCET NEAREST THE WATER TANK IMMEDIATELY AFTER THE BURNER SWITCHES OFF. WATER HEATERS ARE CAPABLE OF SCALDING TEMPERATURES.
