Oil-fired Heaters

Although separate oil-fired units like the one below represent less than 1 per cent of water heaters used in American homes, using oil as fuel to get hot water is not rare. In the cold-weather Northern states and Canada many homes have integrated oil systems that use a single burner to provide both heat and hot water. These systems work so efficiently that few require the addition of a separate water heater. In places where a separate oil-fired water heater is desired, it performs remarkably well. A typical unit can heat a tank full of cold water to piping hot about three times faster than a gas heater can do it, and about five times faster than an electrical heater can normally function.
How a relief value works
A double safeguard for oil-fired and other types of water heaters, the temperature- pressure relief valve is activated when the water pressure on the disc exceeds 150 pounds per square inch or when a temperature of 2100 causes the thermostat element to expand. In either case, the disc is forced up and water escapes through the discharge opening. A lever manually operates the valve for testing.
How an oil-fired water heater works
Triggered by the thermostat control, an oil burner ignites a mixture of fuel and air with an electric spark in the water-heater combustion chamber, exactly as it does in an oil-burning home heating system. The water heater shown here holdsthe water in a”floater tank” one suspended so that hot gases flow over the entire tank surface (arrows) before being vented through the flue.

Thermostat control
The thermostat control of an oil-fired water heater is regulated by a vapor-filled sensing bulb, much like those used in gas ranges, that protrudes into the water in the tank. As the water heats, the vapor expands, passing through tubing to push open an electrical contact and shut off the burner circuit. The vapor will contract as the water cools. allowing the contact to close and restart the burner.

Electric Water Heaters
The tank and plumbing of an electric water heater are basically the same as those of gas units. But electric heating elements and their controls are much less complicated than the burners and valves of other kinds of water heaters: they contain no moving parts other than slowly curling bimetallic strips in the thermostats. This simplicity lets you test the water heater and repair it on the rare occasions when it breaks down. Before you begin, check the fuse or circuit breaker. If the fuse is blown or if the circuit breaker has tripped, then test the heating elements. But first be sure there is no power going to the water heater. If the fuse is all right, start your troubleshooting.
Inside an electric water heater
Electric water heaters will usually have two heating elements controlled by simple thermostats that can sense water temperature through the tank wall. To limit demand on the house electrical supply, the thermostats allow only one element at a time to heat. First the upper element heats the water in the top of the lank. then it turns off while the lower element heats the rest of the water. As hot water is used from the top of the tank. the bottom element turns on to heat the cold water that enters the tank through the dip tube. Should so much hot water be used that the temperature in the top of the tank falls below the thermostat setting. the upper element comes back on. This will quickly provide additional hot water at the top of the tank. A high-temperature cutoff turns off power to the water heater if it malfunctions in such a way that the water temperature increases to 2100.
