It's important to understand how to use a propane patio heater if you want to stay warm in the cold weather. Matthew Griffith, chief of the prevention division at Montreal's Fire Department, says that shoppers should be looking for products that have safety certifications.
It's also crucial to ensure that there are no nearby combustible objects and that the patio heater is correctly attached.
Pressure Regulator
Gas regulators are simple mechanical appliances we use in our vehicles and homes every day without giving them a second glance. 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 variety of variations in the design of regulators, but their basic function is the same. The regulator utilizes an element that senses pressure typically a fabric-reinforced diaphragm, to control the position of the valve plug 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, then into the valve. The mechanism is able to detect the gas pressure in the home or pipeline and adjusts the valve plug's position to meet the demand. As the use of gas in the house decreases, the pressure between the regulator and the house reduces as well. The diaphragm expands downwards and the valve plug moves closer to the orifice in order to limit the flow. As the demand for gas powered patio heater in the home increases the valve expands, increasing the flow of gas.
When the valve plug is shut, it is held in position by the spring force until the demand of the house decreases, which opens the valve further to increase the flow. This process is called sizing and it is the primary function of the regulator.
As the valve opens, a pressure is built up in the main chamber of the regulator, which is connected to the hose outlet port by a venturi tube (see image). This pressure is controlled by adjusting a 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 lowers the pressure.
When choosing a regulator for pressure, keep in mind that the maximum and minimum nominal pressure is dictated by commercial standards, not the pressure of the gas at the supply line. The regulator must also be compatible with the hose you use. Look for a hose labeled whistle-free. It will feature alternating rings that are different sizes. This will stop resonant noises from building across the length.
Thermocouple
Thermocouples are based on the idea that different metals when in contact at their respective ends can generate a voltage, even if they are operating at extremely different temperatures. They are used to detect the temperature difference between two points in a system and convert this information into an electrical signal that can be read by thermocouple meter or another instrument. Thermocouples possess several advantages over other sensors like thermistors, including the ability to measure very high-temperatures and to operate in harsh environments.
The measuring (or hot) junction is created by connecting two metals with different properties at one end, while the other end, known as the reference (or cold) junction, is maintained at a constant temperature. Thermocouples are passive devices, which means that they don't require power in order to function. The voltage generated is proportional to the difference in temperature between the measuring and reference junctions. 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 primary types of thermocouple junctions- an exposed, grounded, and weld wire. The type of junction that is exposed protrudes from the protective sheath and provides the fastest response. A thermocouple that is grounded is recommended for measurements in corrosive environments. A thermocouple welded to a wire is physically insulated from the sheath with mgO powder to prevent penetration of moisture or gas that could cause errors.
The welded wire thermocouple has the additional benefit of being more resistant to vibration. It is recommended to use it in abrasive environments that require pressures up to 3000 psi. If a thermocouple is damaged, it's usually caused due to a lack of polarity. If the sheath is not properly polarized, the two ends of the thermocouple have different voltages at the junction of measurement which could result in an inaccurate reading and even end up damaging the instrument. A sensor that isn't properly calibrated or placed in the right place can cause a malfunctioning thermocouple.
Thermostat
black gas patio heater patio heaters unlike electric heaters which are hardwired to the wall are portable and operate on propane or natural gas. Thermostats regulate the flow energy into these cylinders to ensure that they don't overflow, but they still provide heat as needed. The thermostat is able to detect the temperature of air passing over it. The thermostat also determines if the room is cooling down to a comfortable level and shuts off the heating.
Digital thermostats are the most common. It is controlled by a microcontroller which converts a fluctuating electrical resistance into a measurement of temperature. It is able to accomplish this more accurately than older, mercury switch thermostats that utilized a mercury coil that had three wires that moved according to the temperature. This enabled it to tilt a mercury switch that was connected to the electrical circuit of a heater or air conditioning unit, and turn it off or on.
Another type of thermostat is one that's mechanical. The thermostat is activated when the wax contained in a small cylinder starts to melt, which is around 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 contracts and the rod is pulled back into the cylinder, shutting the valve.
There are also thermostats that can be programmed to change at different times during the day. This lets you save energy by setting your heating to come off and on when you are at work or asleep, instead of having it on continuously. You can also set your thermostat to turn on sooner so that you will arrive home to an ideal temperature. Thermostats often have an element known as the heat anticipator, which prevents the heater from turning on too soon. This is due to the fact that different areas of the home often attain the temperature set before the thermostat itself.
Pilot Light
While many modern heating and homes have eliminated pilot lights, older homes and furnaces still use these devices to light the gas in the chamber for burning. It's important to learn how to safely restart the pilot light if it ever goes out.
A pilot light creates a small flame that heats a thermocouple, which generates electricity and holds the gas valve open. When the pilot flame ceases to burn, the thermocouple cools down and ceases to produce electricity, closing the valve. Pilot lights are found in the majority of propane and natural gas patio heater appliances, including water heaters, fireplaces, barbecues, furnaces, ranges and hot tubs.
To relight a pilot light, you first need to shut off the gas in the appliance. You will then need to remove any panels or doors that could be blocking 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 lit the pilot light, turn the gas valve knob to the "on" position.
The primary reason to keep a pilot light on is to ensure safety. If you accidentally turn off the pilot light, the gas that is constantly escaping from the tube can build up in your home until an electric spark or static charge sparks the gas powered patio heater, causing an explosive explosion. Pilot tubes are designed to contain an inbuilt cutoff valve to keep this from happening.
A constantly burning pilot light is not only dangerous, but it also wastes energy. Various studies have shown that a pilot light can consume between $7 and $18 of gas every month. This waste of fuel also puts an additional burden on the air cooling system during summer time. Another issue with a pilot light is that it attracts spiders, who can spin webs that can clog pilot tubes. A constant flame can emit small amounts of the compound Mercaptan which is responsible for the smell of rotten eggs in natural gas gas patio heater gas. If you're ever worried about these problems, consider buying a remote controlled gas fireplace or replacing your old fireplace with a more modern efficient model.
