It's crucial to know how to use a propane patio heater if need to stay warm during the cold winter. Matthew Griffith, chief of the prevention section of Montreal's Fire Department advises that consumers look for products with safety certifications.

It's also essential to ensure that there are no nearby combustible objects and that the patio gas heater is properly connected.

Pressure Regulator

gas patio heater outdoor regulators are a simple mechanical devices that we drive through every day in our cars and at home without giving them a second thought. Their invention created 135 years ago, changed the way natural gas and propane is used for heating, cooking and oxyfuel welding. The basic role of regulators is exactly similar, but there are many variations. The regulator utilizes an element that senses pressure, typically a fabric-reinforced dialythm to regulate a valve plug's location and limit the flow of gas.

The diaphragm is connected to the stem of the valve by a rod that runs through the set spring, over the diaphragm and into the valve. The gas pressure from the pipeline or the house is detected by this mechanism and it adjusts position of the valve plug to align it to the demand from the house. As the consumption of gas in the house decreases and the pressure between the regulator and the house decreases also. The diaphragm begins to decrease in size, and then it moves the valve plug closer to the orifice, limiting the flow. As the demand for gas increases in the home, the valve opens more, thereby increasing the flow.

When the valve plug is closed it is held in position by the spring force until the house's demand decreases, which then opens the valve further to increase the flow. This process, referred to 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 via a venturi tube. This pressure can be adjusted by adjusting the screw or handle located on the outside regulator. When the screw is turned counterclockwise, it moves up and reduces the pressure; when it is turned clockwise it decreases the pressure.

When choosing a regulator for pressure be aware that the nominal maximum and minimum pressure is determined by commercial standards and not the pressure of the gas at the supply line. The regulator must be compatible with the hose you choose to use. Find a hose that is whistle-free, which will feature alternating rings of different sizes to prevent resonant sounds from building up along the length of the hose.

Thermocouple

Thermocouples operate on the principle that two dissimilar metals in contact at each end produce a voltage even if they are at different temperatures. They are used to determine temperatures that differ between points of a circuit and convert that information into an electronic signal that can be read by thermocouple gauges or another instrument. Thermocouples are superior to other sensors, like thermistors. They can measure extremely high temperatures and function in corrosive environments.

A pair of metals that are dissimilar is joined at one end of the sensor, forming the measuring (aka hot) junction, while the other is kept at a fixed temperature, known as the reference (aka cold) junction. Thermocouples are passive devices meaning they don't require power in order to function. The voltage generated is proportional to the temperature difference between the measuring and reference junctions. 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 specific type of thermocouple.

There are three main kinds of thermocouple junctions: an exposed, grounded and weld wire. The type of junction that is exposed extends out of the protective sheath, and provides the fastest response. A thermocouple grounded is recommended for use in environments with corrosive elements. A thermocouple that is welded is physically separated from the sheath using mgO powder to prevent penetration of gas or moisture that could cause errors.

The thermocouple welded wire has the additional benefit of being more vibration resistant. It is recommended to use it in harsh environments with pressures of up to 3000 psi. If a thermocouple becomes damaged, it is usually caused by a lack of polarity. If the sheath has not been polarized, both ends of the thermocouple might have different voltages at their junction for measurement. This could result in an incorrect reading or damage the instrument. A sensor that is not properly calibrated or installed could cause a malfunctioning thermocouple.

Thermostat

In contrast to electric heaters that need to be hardwired into the wall gas cheap patio gas heaters are portable and utilize natural gas or propane cylinders to fuel. The thermostats regulate the flow energy to these cylinders in order that they don't overflow but they still provide heat when required. The thermostat detects the temperature of air passing over it. The thermostat also determines that the room is at a comfortable temperature and turns off the heating.

The most commonly used type of thermostat is one that is digital. It uses a microcontroller that converts a changing electrical resistance into a measurement of temperature. It is able to do this much more accurately than the older mercury switch thermostats that used a mercury coil with three wires that moved in accordance with the temperature. This allowed the thermostat to tilt a mercury switch that was connected to an electrical circuit that was used to power the air conditioner or heater patio gas, turning it on and off.

A mechanical thermostat is a different kind. This has tiny cylinders filled with wax that starts to melt at a temperature of perhaps 180 degrees F (different thermostats open up at different temperatures). When the wax is hot, a rod that is connected to the thermostat opens the valve. As the room cools the wax shrinks and the rod is pulled into the cylinder, closing the valve.

You can set thermostats to change the temperature at different times during the day. You can cut down on energy consumption by programming your heating to be turned off and on while you are at work, or sleeping, rather than having it always on. You can also set your thermostat to come on sooner so that you will arrive home to an appropriate temperature. Thermostats are also usually equipped with a feature called the heat anticipateor which stops the heater from switching off too early. This is because some parts of the home reach the desired temperature before the thermostat has even been set.

Pilot Light

While many modern homes and heating systems have eliminated pilot lights older furnaces and homes still rely on these devices to light the gas in the chamber for burning. It is important to know how to safely relight the pilot light if it ever fails.

A pilot light produces tiny flames that heat a thermocouple, which generates electricity and holds the gas valve open. When the pilot flame goes off the thermocouple cools and ceases to produce electricity, thus closing the valve. Pilot lights are used in most natural and propane-fueled appliances, including water heaters, fireplaces, barbecues, grills, furnaces and hot tubs.

To relight a pilot, you must first turn 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 carefully follow the instructions 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 for leaving the pilot light on is for safety reasons. If it's accidentally shut off, the gas that is constantly escaping from the pilot light tube could build up in your home until a spark from a cigarette lighter or static electricity ignites it and causes an explosion. The tubes designed for pilots have a built-in cutoff valve to keep this from happening.

In addition to the safety issues that a burning pilot light is also considerable energy. A pilot light burns between $7 and $18 worth of gasoline every month, based on different studies. The wasted fuel creates a greater burden on the air conditioner during summer. Another concern with pilot lights is that it could attract spiders, who can spin webs that can clog pilot tubes. Finally, a constant flame could release trace amounts the mercaptan compound, which produces the rotten egg smell found in natural gas. If you're worried about these issues, you should consider buying a remote controlled gas fireplace or replacing your old fireplace with a more modern efficient model.
