Gas Patio Heater Regulator
If you're looking to cozy with the cold outside with a propane patio heater, it's important to be aware of how to use the appliance. Matthew Griffith, prevention section chief of the Montreal fire department, advised that customers should look for items that have safety certifications.
It's also important to ensure that there are no nearby combustible objects and that the patio gas heater is correctly attached.
Pressure Regulator
Gas regulators are a simple mechanical devices that we pass through every day in our cars and at home without giving them a second thought. Their invention, made 135 years ago, has changed the method in which propane and natural gas are used for cooking, heating, and oxy-fuel welding. The basic function of regulators is similar, but there are numerous variations. The regulator is based on an element that senses pressure, typically a fabric-reinforced dialythm to regulate a valve plug's position and limit gas flow.
The diaphragm is linked to the stem of the valve using rods that run down through the set spring, through the diaphragm, and finally into the valve. The pressure of gas coming from the pipeline or the house is detected by this mechanism and it adjusts position of the valve plug to align it with the demand from the house. As the use of gas in the house decreases the pressure between the regulator and the house also decreases too. The diaphragm is deflated downward and the valve plug moves closer to the orifice to restrict the flow. As the demand for gas grows in the home, the valve opens more, increasing the flow.
When the valve plug is shut, it is held in place by the set spring force until the demand from the house drops, which opens the valve to increase the flow. This process is known as size and is the fundamental function of the regulator.
When the valve is opened the pressure builds up in the main chamber which is connected to the hose's outlet port via venturi tubes. The pressure can be regulated by turning the handle or screw located on the outside regulator. When the screw is rotated counterclockwise, it increases the pressure. When it is rotated clockwise it decreases the pressure.
When selecting a pressure regulator, remember that the maximum and minimum nominal pressures are determined by commercial standards, not the pressure at the supply line. The regulator should be compatible with the hose you are using. Find a hose that is labeled as whistle-free, which will feature alternating rings of different sizes to prevent resonant sound from accumulating throughout the hose.
Thermocouple
Thermocouples work on the principle that different metals in contact with each other at their respective ends can generate an electric current, even when they are at very varying temperatures. They are used to detect the temperature differences between two points in a system and convert this data into an electrical signal that can be read by a thermocouple meter or other instrument. Thermocouples possess several advantages over other sensors, such as thermistors which include the ability to detect extremely high temperatures and to function in corrosive environments.
A pair of metals that are dissimilar are connected at one end of the sensor, forming the measuring (aka hot) junction, and the other end is maintained at a set temperature, known as the reference (aka cold) junction. Thermocouples are passive devices meaning they do not require power to operate. The voltage generated is proportional the temperature difference between the measuring junction and the reference junction. Manufacturers of thermocouples as well as organizations that offer metrology standards, such as NIST, provide reference tables for the function E (T). Displaystyle scriptstyle e(T) For each particular type of thermocouple.
There are three kinds of thermocouple junctions: an exposed, grounded, and weld wire. The exposed style of junction is a bit higher than the protective sheath, and provides the fastest response. A grounded thermocouple is recommended for testing in corrosive environments. A thermocouple welded to a wire is physically separated from the sheath by mgO powder to prevent penetration of moisture or gas that could lead to errors.
The welded wire thermocouple is also a benefit in being more vibration resistant. It is recommended to use it in extreme environments that have pressures up to 3000 psi. When a thermocouple is damaged, it's typically caused by a lack in polarity. If the sheath has not been polarized, both ends of the thermocouple could have different voltages at their measurement junction. This can lead to an incorrect reading or damage the instrument. A malfunctioning thermocouple could be caused by an improperly installed or calibrated sensor.
Thermostat
Unlike electric heaters which have to be wired directly into the wall, gas patio heaters are portable and utilize natural gas fired patio heaters or propane cylinders to fuel. Thermostats control the flow of energy to these cylinders in order they don't spill over, but they still provide heat when required. The thermostat senses the temperature of air passing through it. The thermostat also determines when the room is at a comfortable temperature and shuts off the heating.
The most commonly used type of thermostat is a digital one. It is controlled by a microcontroller which converts a fluctuating electrical resistance into a reading of temperature. It is able to perform this task more accurately than the older mercury switch thermostats, which used an mercury coil with three wires in it that would move based on temperature. This enabled the thermostat to tilt a mercury switch that was connected to an electrical circuit that was used to power the air conditioner or heater patio gas by turning it on and off.
Another type of thermostat is a mechanical one. This has an cylinder of small size filled with wax that starts to melt at a temperature, maybe 180 degrees F (different thermostats open at different temperatures). When the wax is hot, a rod that is connected to the thermostat opens the valve. As the room cools, the wax contracts and the rod is pulled into the cylinder to close the valve.
There are also thermostats that can be programmed to change at different times during the day. You can cut down on energy consumption by programming your heating system to switch off and on when you are at work, or sleeping, rather than being always on. You can also set the thermostat to come on earlier, so that your home will be at a comfortable temperature when you return from school or work. Thermostats often have an element called the heat anticipator that stops the heater from switching on too soon. This is because some parts of the house reach the desired temperature before the thermostat has even been set.
Pilot Light
Many modern heating systems, homes and furnaces are no longer completely of pilot lights. However, older homes still use them to ignite gas in the burner chamber. It's essential to know how to safely restart the pilot light if it ever fails.
A pilot light creates small flames that warm the thermocouple, which produces electricity and keeps the gas valve open. If the pilot flame dies the thermocouple cools down and ceases to generate electricity, thus closing the gas fire patio heater valve. Pilot lights are utilized in most natural and propane-fueled appliances, such as fireplaces, water heaters, barbecues, furnaces, ranges and hot tubs.
Relighting a pilot light requires first that you shut off the gas valve at the appliance. You must then take off any doors or panels that may be blocking the access to the pilot light. Locate the pilot light tube, and follow the instructions on the front of the appliance to open it. Once you've re-lit the pilot light, return the knob on the gas valve to the "on" position.
Safety is the main reason to keep a pilot light lit. If you accidentally turn off the pilot light, gas that is constantly venting out of the tube could build up in your house until a spark or static electricity ignites the gas and causes an explosive explosion. The tubes designed for pilots contain a built-in cutoff valve that can prevent this from happening.
In addition to the safety issues the burning of a pilot light is also considerable energy. Various studies have shown that a pilot light could consume between $7 and $18 of gas per month. This fuel is wasted and creates a greater burden on the air conditioner in summer. A pilot light may attract spiders that can spin webs and block the pilot tubes. Also, a constant flame can release trace amounts of the compound mercaptan, which causes the rotten egg odor found in natural gas. If you're ever worried about these issues, you should consider purchasing a gas fire with a remote control or replacing a fireplace with a more effective, modern-day model.
