If you're planning to warm inside the cold winter air with a propane patio heater gas heater, it's important to know how to properly use this appliance. Matthew Griffith, prevention section chief of the Montreal fire department, said shoppers should choose products that are safe to use.
The patio heater needs to be properly connected and there should be no materials that could ignite nearby.
Pressure Regulator
outdoor gas patio heater regulators are mechanical devices we drive by daily in our cars and homes without a second thought. Their invention, 135 years ago, has revolutionized the way natural gas and propane are used for heating, cooking, and welding with oxy-fuel. There are a number of variations in regulator design, however their fundamental purpose is the same. The regulator uses an element that senses pressure, typically a fabric-reinforced dialythm to control a valve plug's position and restrict the flow of gas.
The diaphragm connects to the stem of the valve by a rod which runs through the diaphragm and set spring and finally into the valve. This mechanism detects gas pressure in the house or pipeline and adjusts the position of the valve plug to match the demand. As the consumption of gas in the home decreases and the pressure decreases between the regulator and the house. The diaphragm is deflated downward and the valve plug moves closer to the orifice in order to restrict flow. As the demand in the home increases, the valve opens further and increases the flow of gas.
The valve plug remains closed until the demand of the house decreases. This opens the valve to increase the flow. This process is known as sizing and it is the fundamental function of the regulator.
As the valve opens it creates pressure up in the main chamber of the regulator, which is connected to the hose outlet port with the venturi tube (see picture). The pressure can be adjusted by turning the handle or screw located on the outside of the regulator. When the screw is turned counterclockwise, it moves up and reduces the pressure. When it is turned clockwise, it lowers the pressure.
When selecting a pressure regulator, keep in mind that the maximum and minimum nominal pressure is dictated by commercial standards, not the pressure of the gas in the supply line. The regulator should also be compatible with the hose you use. Look for a hose that is marked as whistle-free which will feature alternating rings of different sizes to stop resonant sounds from building up across the length of the hose.
Thermocouple
Thermocouples are based on the idea that two different metals in contact at each end produce a voltage, even when they are at different temperatures. They are used to detect the temperature differences between different points in an electrical circuit and convert that data into an electronic signal that can be read by thermocouple gauges or another instrument. Thermocouples are superior to other sensors, for instance thermistors. They can detect extremely high temperatures and work in corrosive conditions.
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 require power to perform their functions. The voltage generated is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers and metrology standards organizations like NIST provide reference tables of the function E (T) displaystyle scriptstyle e(T) For each particular type of thermocouple.
There are three kinds of thermocouple connections: exposed grounded and weld. The exposed type of junction extends out of the protective sheath and has the fastest response. A thermocouple that is grounded is recommended for use in environments with corrosive elements. A welded wire thermocouple is physically separated from the sheath with mgO powder to prevent the penetration of moisture or gas which could cause mistakes.
The welded wire thermocouple also has the added benefit of being more vibration resistant. It is recommended for use in harsh environments and at pressures up to 3000 psi. When a thermocouple is damaged, it's usually caused due to a lack of the polarity. If the sheath has not been correctly polarized, the two ends of the thermocouple could have different voltages at their junction for measurement. This can result in an incorrect reading or damage the instrument. A sensor that isn't properly calibrated or installed can also result in a malfunctioning thermocouple.
Thermostat
Gas patio heaters, unlike electric heaters that are hardwired to the wall are portable and operate on propane gas patio heater or natural gas. Thermostats regulate flow of energy into these cylinders to ensure that they don't overflow, but they still provide heat as needed. The thermostat detects the temperature of the air passing over it. The thermostat also detects when the room has been cooled to a comfortable temperature, and shuts off the heating.
The most commonly used type of thermostat is a digital device. It utilizes a microcontroller in order to convert an electrical resistivity into an indication of temperature. It can do this more accurately than previous mercury switch thermostats, which employed a mercury coil with three wires inside that moved based on temperature. This enabled it to tilt a mercury switch connected to the electrical circuit of an air conditioning or heater unit, and turn it off or on.
Another type of thermostat is one that is mechanical. This has tiny cylinders filled with wax that begins to melt at a certain temperature, maybe 180 degrees F (different thermostats are open at different temperatures). A rod that is connected to the valve presses into this wax and opens the valve when it's hot. As the room cools, the wax contracts and the rod is pulled back into the cylinder, shutting the valve.
You can also program thermostats to change the temperature at different times throughout the day. You can reduce energy usage by setting your heating to switch off and on when you are working, or sleeping, rather than having it on all the time. You can also set the thermostat to come on earlier so that your home is a comfortable temperature when you return from work or school. Thermostats are also usually equipped with an element called the heat anticipator that prevents the heater from turning on too quickly. This is due to the fact that different areas of the home often attain the temperature set before the thermostat itself.
Pilot Light
Many newer 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. If the pilot light is ever shut off, it's crucial to know how to light it safely.
A pilot light produces a small flame that heats a thermocouple, which generates electricity and holds the gas valve open. When the pilot flame stops the thermocouple cools and stops producing electricity, closing the valve. Pilot lights are used on the majority of propane and natural gas appliances, such as water heaters.
To relight a pilot light, you must first turn off the gas on the appliance. Then, you have to take out any doors or panels that may be blocking accessing the pilot light. Find the pilot light tube, and follow the instructions on the back of the appliance to open it. After you've lit the pilot light, turn the knob on the gas valve to the "on" position.
The main reason to leave a pilot light on is for safety reasons. If it's accidentally turned off, the gas that is constantly venting out of the pilot light tube may build up in your home until a spark from a spark from a cigarette lighter or static electricity ignites it and causes an explosion. Pilot tubes are designed to include a built-in cutoff valve to keep this from happening.
A constantly burning pilot light is not only dangerous but also wastes energy. Different studies have proven that a pilot light can consume between $7 and $18 worth of gas per month. This waste of fuel also puts a heavier load on the air conditioning system during summer use. A pilot light can also draw spiders, which can spin webs and block up the pilot tubes. Also, a constant flame can emit trace amounts of the mercaptan compound that produces the rotten egg smell that is found in natural gas. If you're worried about these issues, you should consider getting a remote control Gas patio heaters UK fireplace or replacing your old fireplace with a more modern efficient and efficient model.
