It is important to know how to use a propane patio heat if you want to stay warm in the cold weather. Matthew Griffith, chief of the prevention department of Montreal's Fire Department says that shoppers should be looking for products that have safety certifications.
It's also crucial to make sure that there are there are no nearby combustible objects and that the Best patio heater gas heater is securely attached.
Pressure Regulator
Gas regulators are a simple mechanical devices that we pass by daily in our cars and homes without giving a second thought. Their invention, which took place 135 years ago, revolutionized the way natural gas and propane are utilized for cooking, heating and welding with oxy-fuel. There are many variations in regulator design, however their fundamental purpose is the same. The regulator utilizes a pressure sensing element which is usually a fabric reinforced diaphragm, to control the position of the valve plug and restrict the flow of gas.
The diaphragm is linked to the stem of the valve by a rod that runs down through the set spring, over the diaphragm before entering the valve. The gas pressure from the pipeline or from the house is detected by this mechanism and it adjusts the position of the valve plug to match it with the demand from the house. As the gas usage in the house decreases, the pressure between the regulator and the house also decreases also. The diaphragm is deflated downward and the valve plug is moved closer to the orifice in order to limit flow. As the demand for gas increases in the home, the valve opens more, increasing the flow.
The valve plug is closed until the demand of the house decreases. This opens the valve to increase the flow. This process, also known as"sizing," is the primary operation of the regulator.
As the valve opens it creates pressure in the main chamber, which is connected to the outlet port of the hose by a venturi tube. This pressure is regulated by adjusting a screw or handle located on the outside of the regulator. When the screw is turned counterclockwise, it increases the pressure. When it is rotated clockwise, it reduces the pressure.
When selecting a pressure regulator take into consideration that the nominal maximum and minimum pressure is dictated by commercial standards and not the pressure of the gas at the supply line. The regulator should also be compatible with the hose. Choose a hose which is marked as whistle-free that has various sizes of rings to prevent resonant sounds from building up throughout the hose.
Thermocouple
Thermocouples are based on the concept that two different metals in contact at either end produce a voltage even when they are at different temperatures. They are used to detect the temperature differences between two points in a system, and transform this information into an electrical signal that can be read by a thermocouple meter or other instrument. Thermocouples offer a number of advantages over conventional sensors, such as thermistors which include the ability to detect extremely high temperatures and operate in corrosive environments.
The measuring (or hot) junction is created by connecting two dissimilar metals at one end, while the other end, known as the reference (or cold) junction, is kept at a constant temperature. Thermocouples produce small voltages, however, they're passive devices that do not require power to work. The voltage generated is proportional to the difference in temperatures between the reference and measuring junctions. Thermocouple manufacturers and metrology standards organizations such as NIST provide reference tables of the function E (T) Displaystyle scriptstyle e(T) for each type of thermocouple.
There are three types of thermocouple junctions: an exposed, grounded and weld wire. The exposed type of junction extends out of the protective sheath and offers the fastest response. A thermocouple that is grounded is recommended for measurements in corrosive environments. A welded-wire thermocouple is physically separated from the sheath by using mgO powder. This stops gas or moisture from leaking into the sheath and causing error.
A welded wire thermocouple also has the added benefit of being more resistant to vibration. It is recommended for use in harsh environments and at pressures of up to 3000 psi. When a thermocouple is damaged, it's typically caused by a lack of polarity. If the sheath isn't polarized, the two ends of the thermocouple will have unequal voltages at the junction of measurement which could result in an inaccurate reading and possibly cause damage to the instrument. A sensor that is not properly calibrated or installed can also result in a malfunctioning thermocouple.
Thermostat
Unlike electric patio heater vs gas heaters which have to be wired into the wall gas patio heaters are portable and utilize propane or natural gas cylinders to fuel. Thermostats regulate flow of energy into these cylinders to ensure that they do not overflow but still provide heat as needed. The thermostat senses the temperature of air passing through it. The thermostat also determines when the room is at a comfortable temperature and turn off the heating.
Digital thermostats are the most common. It is controlled by a microcontroller which converts a changing electrical resistance into a reading of temperature. It can do this more accurately than previous mercury switch thermostats that used an mercury coil with three wires that would change according to 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 on or off.
Another type of thermostat is one that is mechanical. The thermostat is opened when the wax in a small cylinder starts to melt, which is approximately 180 degrees F. (Different thermostats have different opening temperatures). A rod that connects to the valve presses into the wax and opens the valve when it's hot. As the room cools down the wax expands and the rod is pushed into the cylinder to close the valve.
You can set thermostats to change the temperature at different time of the daytime. This allows you to reduce energy consumption by setting your heating to come off and on when you are working or asleep, instead of being constantly on. You can also set your thermostat to turn on sooner so that you can get home to an appropriate temperature. Thermostats usually have a feature called a heat anticipator that stops the heater from turning on too early. This is due to the fact that certain areas of the home are at the desired temperature prior to the thermostat.
Pilot Light
While many modern heating and home systems have eliminated pilot lights older furnaces and homes still use them to light the gas in the burner chamber. If the pilot light is ever snuffed out, it's vital to know how to relight it safely.
A pilot light produces tiny flames that heat a thermocouple. This thermocouple generates electricity, and keeps the gas patio heater valve open. When the pilot flame stops, the thermocouple cools down and ceases to produce electricity, thereby closing the valve. Pilot lights are used in the majority of propane and natural appliances, such as water heaters, fireplaces, furnaces, ranges, barbecues and hot tubs.
To light a pilot light, it is necessary that you first shut off the gas valve at the appliance. Then, you have to take out any doors or panels that could hinder getting to the pilot light. Find the pilot light tube and carefully follow the instructions on the front of the appliance for opening it. Once you've reopened the pilot then turn the knob on the gas valve to "on".
The main reason to leave a pilot light on is to ensure safety. If it's accidentally shut off, the gas that is constantly escaping from the pilot light tube can accumulate in your home until a spark from a cigarette lighter or static electricity ignites it and triggers an explosion. To prevent this, the pilot tubes come with a built in cutoff valve.
Apart from the safety concerns the burning of a pilot light is also a significant amount of energy. Numerous studies have revealed that a pilot light could consume between $7 and $18 worth of gas every month. The wasted fuel also puts a heavier load on the air cooling system in summer. A pilot light can also attract spiders which can spin webs, and clog the pilot tubes. Also, a constant flame can release trace amounts of the compound mercaptan, which causes the rotten egg odor that is present in natural garden gas patio heater. If you're ever concerned about these issues, think about buying a remote-controlled gas fire or replacing your fireplace with a more efficient, modern design.
