Gas Patio Heater Regulator
If you're looking to cozy inside the cold winter air with a propane patio heater gas regulator heater, it's important to understand how to use the appliance. Matthew Griffith, chief of the prevention department of Montreal's Fire Department says that shoppers should look for products with safety certifications.
The patio heater should be securely attached and there should be no materials that could ignite nearby.
Pressure Regulator
Gas regulators are mechanical devices that we pass by daily in our cars and homes without a second thought. Their invention, made 135 years ago, has changed the way propane and natural gas are used for cooking, heating, and oxy-fuel welding. The fundamental purpose of regulators is the same, however there are numerous variations. The regulator utilizes an element that senses pressure which is usually a fabric reinforced diaphragm, to control the position of a valve plug and limit the flow of gas.
The diaphragm is connected to the stem of the valve by rods that go down through the set spring, up through the diaphragm before entering the valve. The pressure of gas coming from the pipeline or from the house is sensed by this mechanism and it adjusts position of the valve plug to match it to the demand of the house. As the gas usage in the house decreases the pressure between the regulator and the house reduces as well. This causes the diaphragm to decrease in size, and then it moves the valve plug closer to the orifice, which limits flow. As the demand for gas increases in the home the valve will open more, thereby increasing the flow.
The valve plug is closed until the demand for the house decreases. The valve is then opened to increase the flow. This process, also known as"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 by a venturi tube. This pressure is regulated by changing the screw or handle on the outside of the regulator. When the screw is turned counterclockwise, it increases the pressure. When it is turned clockwise, it decreases the pressure.
When you are choosing a regulator for your pressure make sure to keep in mind that the maximum and minimum nominal pressures are determined by commercial standards, not the pressure at the supply line. The regulator must be compatible with the hose you choose to use. Look for a hose that is marked as whistle-free that has alternating rings of different sizes to prevent resonant sounds from accumulating along the length of the hose.
Thermocouple
Thermocouples operate on the premise that different types of metals in contact with each other at their respective ends can generate an electric current, even when they are at wildly different temperatures. They are used to determine the temperature differences between different points in 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 work in corrosive conditions.
A pair of metals that are dissimilar is connected at one end of the sensor, forming the measuring (aka hot) junction, and the other is kept at a constant temperature, also known as the reference (aka cold) junction. Thermocouples create small voltages but they are passive devices that don't require power to function. The voltage generated is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers and metrology standard organizations like NIST provide reference tables of the function E (T) Displaystyle scriptstyle e(T) For each type of thermocouple.
There are three kinds of thermocouple connections: exposed, grounded and weld. The exposed style of junction is a bit higher than the protective sheath and offers the fastest response time. In the event of measurements under corrosive conditions, a grounded thermocouple should be used. A thermocouple that is welded is physically isolated from the sheath using mgO powder. This prevents moisture or gas from penetrating and causing error.
A thermocouple welded to a wire comes with the added benefit of being more resistant to vibration. It is recommended to use it in extreme environments with pressures of up to 3000 psi. A thermocouple that has been damaged is usually caused by the lack of polarity. If the sheath does not appear to be properly polarized, the two ends of the thermocouple have different voltages at the measurement junction, which can cause an inaccurate reading and even end up damaging the instrument. A faulty thermocouple can also be caused by an improperly installed or calibrated sensor.
Thermostat
Gas patio gas heaters, unlike electric heaters that are hardwired to the wall, are portable and are powered by natural gas or propane. Thermostats regulate the flow of energy into these cylinders to ensure that they do not overflow, but they still provide heat as needed. The thermostat accomplishes this by detecting the temperature of the air that flows over it. The thermostat also determines that the room is at a comfortable temperature and shuts off the heating.
The most common type of thermostat is a digital device. It uses a microcontroller to convert an electrical resistivity into an indication of temperature. It is able to perform this more accurately than the older mercury switch thermostats, which used a mercury coil with three wires in it that would move based on temperature. This allowed it to tilt a mercury switch that was connected to the electrical circuit of the air conditioning or heater unit, turning it on or off.
Another type of thermostat is one that is mechanical. The thermostat opens when the wax in the small cylinder begins to melt, which is around 180 degrees F. (Different thermostats have different opening temperatures). A rod that connects to the valve is then pressed into the wax, and opens the valve when it's hot. As the room cools down, the wax contracts and the rod is pushed into the cylinder, closing the valve.
There are also thermostats that can be programmed to alter at different times during the day. This allows you to conserve energy by setting your heating to come on and off when you are at work or sleeping, rather than having it on constantly. You can also set the thermostat to come on earlier so that your home is at a comfortable temperature when you arrive back from work or school. Thermostats also often include an option known as the heat anticipator, which prevents the heater from turning off too early. This is because certain parts of the house reach the desired temperature before the thermostat has even been set.
Pilot Light
While many modern heating and home systems have done away with pilot lights older furnaces and homes still rely on these devices to light gas fired patio heaters in the burner chamber. If the pilot light ever extinguished, it's important to know how to relight it in a safe manner.
A pilot light creates a small flame which heats the thermocouple. The thermocouple produces electricity, and keeps the gas or electric patio heater valve open. When the pilot flame stops, the thermocouple cools down and ceases to produce electricity, thus closing the valve. Pilot lights are utilized in most natural and propane-fueled appliances, including fireplaces, water heaters, barbecues, furnaces, ranges and hot tubs.
To relight a pilot light, you first need to shut off the gas at the appliance. You will then need to remove any panels or doors that may be blocking the access to the pilot light. Find the pilot light tube and follow the steps on the back of the appliance for opening it. After you've lit the pilot light, return the gas valve knob to the "on" position.
The main reason to leave a pilot light on is for safety reasons. If it's accidentally shut off and the gas that's constantly venting out of the pilot light tube may build up in your home until sparks from a smoking cigarette or static electricity ignites it, causing an explosion. The tubes designed for pilots include a built-in cutoff valve that can keep this from happening.
In addition to the safety issues that a burning pilot light also consumes a significant amount of energy. A pilot light can burn between $7 and $18 worth of gas each month, according to numerous studies. This wasted fuel also places more strain on the air conditioning system during summer use. Another issue with the pilot light is that it can attract spiders, which can spin webs that clog the pilot tubes. A flame that is constant can release tiny amounts of the chemical Mercaptan which is responsible for the smell of rotten eggs that is common in natural gas. If you're ever concerned about these issues, consider purchasing a gas fire with a remote control or replacing your fireplace with a more efficient and modern model.
