If you're planning on cozying inside the cold winter air with a propane patio heater gas regulator heater, it's crucial to be aware of how to make use of this device. Matthew Griffith, prevention section chief of Montreal's fire department, said that consumers should be looking for items that have safety certifications.
It's also essential to ensure that there aren't any combustible materials in the vicinity and that the patio heater is properly attached.
Pressure Regulator
Gas regulators are mechanical devices we drive through every day in our cars and homes without giving a second thought. Their invention, 135 years ago, revolutionized the method in which propane and natural gas are utilized for cooking, heating and oxy-fuel welding. There are a number of variations in the design of regulators, however their fundamental function is the identical. The regulator uses an element that senses pressure, usually a fabric-reinforced dialythm, to control a valve plug's location and limit the flow of gas.
The diaphragm is linked to the stem of the valve using rods that run down through the set spring, up through the diaphragm and into the valve. This mechanism detects gas pressure inside the house or pipeline and adjusts the valve plug's position to match the demand. As the gas consumption in the home decreases as does the pressure between the regulator and the house. The diaphragm expands downwards and the valve plug is moved closer to the orifice to limit flow. As the demand for gas increases in the home the valve will open more, thereby 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, also known as"sizing," is the basic operation of the regulator.
As the valve opens it creates pressure up in the main chamber of the regulator, which is attached to the port for hose outlet via venturi tubes (see the image). This pressure can be adjusted by adjusting the screw or handle located on the outside of the regulator. When the screw is turned counterclockwise, it raises the pressure. When it is rotated clockwise it decreases the pressure.
When you are choosing a regulator for your pressure make sure to keep in mind that the minimum and maximum nominal pressures are established by commercial standards, and not the pressure at the supply line. The regulator must also be compatible with the hose you are using. Find a hose that is marked as whistle-free that has various sizes of rings to prevent resonant sound from building up throughout the hose.
Thermocouple
Thermocouples are based on the principle that two dissimilar metals that are in contact at one end produce a voltage even when they are at different temperatures. They are used to measure the temperature differences 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 have several advantages over other sensors such as thermistors, for instance, the ability to measure extremely high temperatures and to function in environments that are corrosive.
The measuring (or hot) junction is created by connecting two metals with different properties at one end, while at the other, the reference (or cold) junction, is kept at the same temperature. Thermocouples generate small voltages, however, they are passive devices that don't require power to work. The voltage generated is proportional the temperature difference between the measuring junction and the reference junction. Manufacturers of thermocouples and organizations that offer metrology standards, like NIST offer reference tables for 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 type of junction is a bit higher than the protective sheath, and offers the fastest response. A thermocouple grounded is recommended for measurements in corrosive environments. A thermocouple that is welded is physically isolated from the sheath with mgO powder. This prevents gas or moisture from leaking into the sheath and causing error.
A welded wire thermocouple also comes with the added benefit of being more resistant to vibration. It is recommended to use it in harsh environments that have pressures up to 3000 psi. A thermocouple that is damaged is usually caused by a lack in polarity. If the sheath is not correctly polarized, both ends of the thermocouple will have unequal voltages at the junction of measurement that could lead to an inaccurate reading and possibly cause damage to the instrument. A sensor that isn't properly calibrated or installed can also cause a faulty thermocouple.
Thermostat
Gas patio heaters unlike electric heaters which are wired to the wall are portable and operate on natural gas patio heater gas or propane. The thermostats regulate the flow energy to these cylinders, so that they don't overflow, however they can still provide warmth when needed. The thermostat accomplishes this by detecting the temperature of the air that passes over it. The thermostat also can tell that the room is at a comfortable temperature and turns off the heating.
Digital thermostats are the most popular. It utilizes a microcontroller that converts a fluctuating electrical resistance into a reading of temperature. It can perform this more accurately than the older mercury switch thermostats, which utilized mercury coils with three wires inside that moved based on temperature. This allowed the thermostat to tilt a switch made of mercury that was connected to an electrical circuit to an air conditioner or heater by turning it off and on.
Another type of thermostat is one that is mechanical. It's tiny cylinders filled with wax which begins to melt at a certain temperature of maybe 180 degrees F (different thermostats open at different temperatures). A rod that connects to the valve is then pressed into this 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.
There are also thermostats that can be programmed to alter at different times of 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, instead of being running all the time. You can also set your thermostat to come on sooner so that you will arrive home to an ideal temperature. Thermostats often have an option called the heat anticipator that prevents the heater from turning on too soon. This is due to the fact that certain areas of the house reach the desired temperature prior to the thermostat has even been set.
Pilot Light
Many modern heating systems, homes and furnaces have done away completely from pilot lights. However older homes still rely on them to ignite gas in the burner chamber. It is important to know how to safely to relight the pilot light in case 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 produce electricity, thereby closing the gas valve. Pilot lights are utilized in most natural and propane-fueled appliances, such as fireplaces, water heaters barbecues, grills, furnaces and hot tubs.
To relight the pilot, you must first shut off the gas on 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 instructions on the back 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 the pilot light on is to ensure safety. If you accidentally shut off the pilot light, the gas that is constantly venting out of the tube could build up in your house until an electric patio heater vs gas spark or static charge ignites the gas and causes an explosive explosion. Pilot tubes are designed to include a built-in cutoff valve to prevent this from happening.
Apart from the safety concerns that a burning pilot light also consumes a significant amount of energy. Numerous studies have revealed that a pilot light could consume between $7 and $18 of gas per month. This waste of fuel also puts more strain on the air conditioning system during summer use. A pilot light can also attract spiders which can spin webs and clog up the pilot tubes. A constant flame can emit trace quantities of the compound Mercaptan that is responsible for the rotten-egg smell in natural gas. If you are ever concerned about these issues, you should consider buying a remote-controlled gas fire or replacing a fireplace with a more efficient, modern design.
