Gas Patio Heater Regulator
If you're looking to cozy inside the cold winter air with a propane patio heater, it's important to know how to properly use the appliance. Matthew Griffith, chief of the prevention division of Montreal's Fire Department says that shoppers should look for products that have safety certifications.
It's also crucial to make sure that there are there are no nearby combustible objects and that the patio heater is correctly attached.
Pressure Regulator
Gas regulators are a simple mechanical devices that we pass by every day in our vehicles and homes without giving a second thought. Their invention, which was first introduced 135 years ago, has revolutionized how propane and natural gas are used for cooking, heating and oxyfuel welding. There are a variety of variations in regulator design, however their primary function is the same. The regulator utilizes an element that senses pressure typically a fabric-reinforced diaphragm, which controls the position of the valve plug and restrict the flow of gas.
The diaphragm joins the stem of the valve by rod that runs through the diaphragm and spring and finally into the valve. The mechanism is able to detect the gas pressure inside the house or pipeline and adjusts the position of the valve plug to meet the demand. As the consumption of gas in the home decreases and the pressure decreases between regulator and house. This causes the diaphragm of the regulator to decrease in size, and then it moves the valve plug closer to the orifice, restricting flow. As the demand for gas grows in the home the valve opens up more, increasing the flow.
When the valve plug is closed it is held in place by the set spring force until the house's demand decreases, which then opens the valve to increase the flow. This process is called size and is the primary function of the regulator.
When the valve is opened, a pressure is built up in the main chamber of the regulator, which is connected to the port for hose outlet with a venturi tube (see picture). This pressure is controlled by changing the screw or handle on the outside of the regulator. When the screw is turned counterclockwise, it increases and decreases the pressure; when it is turned clockwise, it lowers the pressure.
When selecting a pressure regulator make sure to keep in mind that the minimum and maximum nominal pressures are set by commercial gas patio heaters standards and NOT the pressure at the supply line. The regulator must be compatible with the hose you are using. Make sure you choose a hose that is whistle-free. It will have alternating rings with different sizes. This will prevent the resonant sounds from building up along the length.
Thermocouple
Thermocouples are based on the concept that two different metals that are in contact at one end produce a voltage even if they are at different temperatures. They are used to determine temperatures that differ between points of the circuit and convert that information into an electronic signal that can be read by thermocouple gauges or any other instrument. Thermocouples are superior to other sensors, such as thermostors. They can detect extremely high temperatures and operate in corrosive environments.
The measuring (or hot) junction is formed by joining two metals that are not compatible at one end, and the other end, 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 the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers and metrology standard organizations such as NIST provide reference tables of the function E (T) Displaystyle scriptstyle e(T) For each type of thermocouple.
There are three main types of thermocouple junctions- an exposed, grounded and weld wire. The exposed style of junction extends out of the protective sheath, and provides the fastest response time. For measurements in corrosive conditions, a grounded thermocouple should be employed. A welded wire thermocouple is physically separated from the sheath using mgO powder to prevent penetration of gas or moisture which could cause mistakes.
The welded wire thermocouple is also a benefit in being more vibration resistant. It is recommended to use it in extreme environments that require pressures up to 3000 psi. A thermocouple that is damaged is usually due to the lack of polarity. If the sheath hasn't been polarized, both ends of the thermocouple could have different voltages at their junction for measurement. This can lead to an inaccurate reading, or even damage the instrument. A faulty thermocouple can also result from an incorrectly calibrated or installed sensor.
Thermostat
In contrast to electric heaters that need to be wired into the wall gas patio heaters are portable and use propane or natural gas cylinders for fuel. Thermostats regulate the flow of energy to these cylinders so that they don't overflow, but can still provide heat when required. The thermostat does this by sensing the temperature of the air that flows over it. The thermostat also determines if the room is cooling down to a comfortable level and shuts off the heating.
The most commonly used type of thermostat is a digital one. It utilizes a microcontroller in order to convert an electrical resistivity into a temperature reading. It can do this more accurately than the older mercury switch thermostats, which used a mercury coil with three wires inside that moved based on temperature. This allowed the thermostat to tilt a mercury switch that was connected to an electrical circuit for the air conditioner or heater, turning it off and on.
A mechanical thermostat is another kind. The thermostat opens when the wax inside a small gas patio heater cylinder starts to melt, which is around 180 degrees F. (Different thermostats have different opening temperatures). A rod connected to the valve is then pressed into the wax and opens the valve when it's hot. 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 throughout the day. You can cut down on energy consumption by setting your heating to switch off and on when you are at work, or sleeping, rather than being on all the time. You can also set the thermostat to come on earlier so that your home is at a comfortable temperature when you return from work or school. Thermostats typically come with a feature known as the heat anticipator, which prevents the heating system from turning on too early. This is because parts of the home often reach the set temperature before the thermostat itself.
Pilot Light
While many newer heating and home systems have eliminated pilot lights, older homes and furnaces still use them to light gas in the chamber for burning. It's important to learn how to safely relight the pilot light if it ever fails.
A pilot light produces small flames that are heated by a thermocouple. The thermocouple produces electricity, and keeps the Gas patio heaters UK valve open. If the pilot flame dies the thermocouple cools and ceases to produce electricity, closing the gas valve. Pilot lights are used in the majority of propane and natural appliances, including water heaters, fireplaces, barbecues, furnaces, ranges and hot tubs.
To relight a pilot light, you must first turn off the gas at the appliance. You must then take off any doors or panels that might be blocking access to the pilot light. Locate the pilot light tube, and follow the instructions on the front of the appliance for opening it. After you've re-lit your pilot light, turn the gas valve knob to the "on" position.
The primary reason to keep a pilot light on is for safety reasons. If it's accidentally shut off, the gas that is constantly venting out of the pilot light tube may accumulate in your home until a spark from the smoking cigarette or static electricity ignites it and causes an explosion. To prevent this, pilot tubes have an inbuilt cutoff valve.
Apart from the safety concerns the burning of a pilot light also consumes considerable energy. Numerous studies have revealed that a pilot light could consume between $7 and $18 worth of gas powered patio heater per month. The wasted fuel is a bigger burden on the air conditioner during summer. Pilot lights can draw spiders, which can spin webs, and clog up the pilot tubes. Finally, a constant flame can emit trace amounts of the mercaptan compound, which causes the rotten egg odor that is found in natural gas. If you're ever concerned about these issues, you should consider purchasing a gas patio heater near me fire with a remote control or replacing an old fireplace with a more efficient, modern-day model.
