Gas Patio Heater Regulator
It's important to understand how to use propane patio heater if are looking to keep warm in the cold winter. Matthew Griffith, chief of the prevention division at Montreal's Fire Department, suggests that customers look for products that have safety certifications.
It's also important to make sure that there are no combustible materials are nearby and that the patio heater is securely attached.
Pressure Regulator
Gas regulators are a simple mechanical devices that we drive by daily in our cars and homes without a second thought. Their invention, first introduced 135 years ago, has revolutionized the way natural gas and propane are used for cooking, heating and oxyfuel welding. The basic role of regulators is exactly the same, but there are many variations. The regulator utilizes an element that detects pressure, usually a fabric-reinforced dialythm, to regulate a valve plug's position and limit gas flow.
The diaphragm is connected to the stem of the valve by rod that runs through the diaphragm and spring, then into the valve. The gas pressure coming from the house or the pipeline is sensed by this mechanism and it adjusts the position of the valve plug to match it to the demand from the house. As the gas usage in the house decreases and the pressure between the regulator and the house reduces too. The diaphragm deflates downward and the valve plug moves closer to the orifice to limit the flow. As the demand in the home increases the valve expands and increases the flow of gas.
The valve plug stays shut until the demand of the house decreases. This opens the valve to increase the flow. This process, called"sizing," is the basic operation 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 screw or handle located on the outside of the regulator. When the screw is turned counterclockwise, it increases and decreases the pressure; when it is turned clockwise, it decreases the pressure.
When choosing a pressure regulator, remember that the minimum and maximum nominal pressures are established by commercial gas patio heaters standards, not the pressure at the supply line. The regulator should also be compatible with the hose you are using. Find a hose that is marked as whistle-free that has alternating rings of different sizes to prevent resonant sound from building up across the length of the hose.
Thermocouple
Thermocouples are based on the concept that two different metals in contact at either end produce a voltage even if they are at different temperatures. They are used to detect the temperature difference between two points in a system, and convert this data into an electrical signal that can be read by thermocouple meters or any other instrument. Thermocouples possess several advantages over other sensors like thermistors, including the ability to measure extremely high temperatures and to function in corrosive environments.
The measuring (or hot) junction is formed by connecting two dissimilar metals at one end, and the other end, known as the reference (or cold) junction, is maintained at an unchanging temperature. Thermocouples create small voltages however, they are passive devices that don't need power to work. The voltage generated is proportional to the difference in temperatures between the reference and measuring junctions. Manufacturers of thermocouples as well as organizations that provide metrology standards, such as NIST, provide reference tables for the function E (T). Displaystyle scriptstyle e(T) for each type of thermocouple.
There are three types of thermocouple connections: exposed, grounded and weld. The exposed style of junction is a bit higher than the protective sheath and provides the fastest response time. A thermocouple grounded is recommended for use in environments with corrosive elements. A welded-wire thermocouple is physically isolated from the sheath by using mgO powder. This stops moisture or gas patio heater regulator from penetrating and causing problems.
A welded wire thermocouple also offers the added benefit of being more resistant to vibration. It is recommended to use in harsh environments, and with pressures of up to 3000 psi. If a thermocouple is damaged, it's typically caused by a lack of the polarity. If the sheath isn't properly polarized, the two ends of the thermocouple have different voltages at the junction of measurement that could lead to an incorrect reading and damage the instrument. A defective thermocouple may be caused by an improperly calibrated or installed sensor.
Thermostat
Contrary to electric heaters, which need to be wired into the wall, gas garden patio gas heater heaters are portable and use propane or natural gas cylinders for fuel. Thermostats regulate flow of energy into these cylinders to ensure that they do not overflow but still provide warmth when required. The thermostat senses the temperature of the air passing through it. The thermostat also senses when the room has been cooled to a comfortable level and shuts off the heating.
The most popular type of thermostat is a digital one. It uses a microcontroller to convert an electrical resistance into a temperature reading. It can do this more accurately than the older mercury switch thermostats that utilized a mercury coil with three wires in it that would move based on temperature. This enabled it to tilt a mercury switch connected to the electrical circuit of the air conditioning or heater unit, and turn it off or on.
Another type of thermostat is one that is mechanical. The thermostat is activated when the wax in a small cylinder starts to melt, which is approximately 180 degrees F. (Different thermostats have different opening temperatures). When the wax is hot, a rod connected to the thermostat opens the valve. As the room cools, the wax expands and the rod is pulled back into the cylinder, closing the valve.
You can set thermostats to change the temperature at various times during the day. You can reduce energy usage by programming your heating system to turn on and off while you are working, or sleeping, instead of having it running all the time. You can also set the thermostat to turn on earlier, so that your home is an ideal temperature when you arrive back from work or school. Thermostats often have an option known as the heat anticipator, which stops the heater from switching on too quickly. This is due to the fact that certain areas of the home are at the desired temperature prior to the thermostat is set.
Pilot Light
While many newer heating and home systems have eliminated pilot lights older furnaces and homes still use them to light gas in the chamber for burning. It is important to know how to safely to relight the pilot light in case it ever goes out.
A pilot light creates small flames that warm the thermocouple. This produces electricity and keeps the gas valve open. When the pilot flame stops the thermocouple cools and ceases to produce electricity, thereby closing the valve. Pilot lights are utilized in the majority of propane and natural appliances, such as water heaters, fireplaces, barbecues, grills, furnaces and hot tubs.
Relighting a pilot light requires first that you shut off the gas valve on the appliance. Then you need to remove any doors or panels that might hinder getting to the pilot light. Find the pilot light tube and carefully follow the instructions on the front of the appliance to open it. Once you've reopened the pilot switch, turn the gas valve knob back to "on".
Safety is the main reason to keep the pilot light on. If you accidentally extinguish the pilot light, the gas that is constantly venting out of the tube could accumulate in your house until a spark or static electricity ignites the gas and causes an explosive explosion. The tubes designed for pilots contain an inbuilt cutoff valve to stop this from happening.
A constantly burning pilot light is not just dangerous however, it also consumes energy. Numerous studies have revealed that a pilot light could consume between $7 and $18 of pyramid gas patio heater each month. This fuel is wasted and puts a heavier burden on the air conditioner during summer. Another concern with pilot lights is that it attracts spiders, which could create webs that block the pilot tubes. Also, a constant flame can emit trace amounts of the compound mercaptan, which produces the rotten egg smell that is found in natural gas. If you're concerned about these problems, consider purchasing a remote-controlled gas fire or replacing your old fireplace with a more modern efficient model.
