Gas Patio Heater Regulator
If you're planning on cozying inside the cold winter air with a propane patio heater, it's important to know how to properly use the appliance. Matthew Griffith, chief of the prevention department at Montreal's Fire Department, says that shoppers should be looking for products that have safety certifications.
It's also essential to make sure that there are there are no nearby combustible objects and that the patio heater is properly connected.
Pressure Regulator
Gas regulators are mechanical devices we drive by daily in our cars and homes without a second thought. Their invention, which took place 135 years ago, has changed the way natural gas and propane are used for heating, cooking and oxy-fuel welding. There are a number of variations in regulator design, however their primary purpose is the same. The regulator is based on an element that detects pressure, usually a fabric-reinforced dialythm, to control a valve plug's position and limit gas flow.
The diaphragm joins the stem of the valve by rods that run through the diaphragm and set spring, then into the valve. This mechanism detects gas pressure inside the house or pipeline and adjusts the position of the valve plug to match the demand. As the gas patio heater uk usage in the house decreases and the pressure between the regulator and the house reduces too. This causes the diaphragm of the regulator to decrease in size, and then it pushes the valve plug closer to the orifice, restricting the flow. As the demand for gas grows 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 demand of the house decreases, which opens the valve to increase the flow. This process, also known as"sizing," is the basic operation of the regulator.
As the valve opens the pressure builds up in the main chamber which is connected to the hose's outlet port by venturi tubes. This pressure can be adjusted by adjusting the screw or handle 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 choosing a regulator for pressure take into consideration that the maximum and minimum nominal pressure is determined by commercial standards, not the pressure of the gas in the supply line. The regulator must be compatible with the hose you are using. Choose a hose which is marked as whistle-free which will feature alternating rings of different sizes to stop resonant sounds from accumulating across the length of the hose.
Thermocouple
Thermocouples work on the principle that different types of metals in contact with each other at their ends can generate a voltage, even if they are operating at extremely different temperatures. They are used to detect temperature differences between points in the circuit and transform that data into an electronic signal that can be read by a thermocouple gauge or other instrument. Thermocouples offer a number of advantages over more common sensors like thermistors, which include the ability to detect extremely high temperatures and to function in environments that are corrosive.
A pair of dissimilar metals is connected at one end of the sensor to form the measuring (aka hot) junction, while the other end is maintained at a set temperature, also known as the reference (aka cold) junction. Thermocouples are passive devices which means that they do not require power to operate. The voltage generated is proportional to the difference in temperature 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 connections: exposed grounded and weld. The type of junction that is exposed protrudes from the protective sheath and offers the fastest response. A thermocouple grounded is recommended for use in environments with corrosive elements. A thermocouple that is welded is physically isolated from its sheath by using mgO powder. This prevents moisture or gas patio heater outdoor from penetrating 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 extreme environments that have pressures up to 3000 psi. A thermocouple that has been damaged is usually caused by the lack of the polarity. If the sheath does not appear to be correctly polarized, both ends of the thermocouple will have unequal voltages at the measurement junction that could lead to an inaccurate reading and even damage the instrument. A defective thermocouple may be caused by a poorly calibrated or installed sensor.
Thermostat
Unlike electric heaters which have to be wired into the wall, gas patio heaters are portable and use natural gas or propane cylinders as fuel. Thermostats control the flow of energy to these cylinders so they don't spill over, but they still provide warmth when needed. The thermostat senses the temperature of the air that passes over it. The thermostat also detects when the room has cooled down to a comfortable temperature, and switches the heating off.
Digital thermostats are the most common. It utilizes a microcontroller in order to convert a changing electrical resistivity into a temperature reading. It can do this much more accurately than earlier mercury switch thermostats that utilized a coil of mercury with three wires in it that moved according to the temperature. This enabled it to tilt the mercury switch connected to the electrical circuit of the air conditioning or heater unit, turning it off or on.
Another type of thermostat is a mechanical one. The thermostat is opened when the wax in the small gas patio heater cylinder begins to melt, which is about 180 degrees F. (Different thermostats have different opening temperatures). When the wax is hot, a rod attached to the thermostat opens the valve. As the room cools, the wax expands and the rod gets pulled back into the cylinder, thereby shutting the valve.
There are thermostats that can be programmed to switch at different times during the day. This allows you to save energy by setting your heating to turn on and off during times of work or asleep, instead of having it on constantly. You can also set the thermostat to come on earlier so that your home is a comfortable temperature when you arrive back from school or work. Thermostats usually include a feature called a heat anticipator, which will stop the heating system from turning on too early. This is due to the fact that different areas of the house typically reach the set temperature before the thermostat itself does.
Pilot Light
While many newer heating and homes have done away with pilot lights, older homes and furnaces still rely on these devices to light gas in the chamber for burning. If the pilot light ever extinguished, it's important to know how to relight it safely.
A pilot light generates tiny flames that heat the thermocouple. This produces electricity and holds the gas valve open. If the pilot flame ceases to burn the thermocouple cools down and ceases to produce electricity, thereby closing the gas valve. Pilot lights are found in the majority of propane and natural appliances, including fireplaces, water heaters, barbecues, grills, furnaces and hot tubs.
To light a pilot light, it is necessary that you first turn off the gas valve in the appliance. The next step is to remove any panels or doors that may be blocking the access to the pilot light. Locate the pilot light tube, and follow the procedure printed on the back of the appliance to open it. Once you've switched off the pilot switch, turn the knob of the gas valve back to "on".
The primary reason to keep the 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 a spark or static electricity ignites the gas patio heater sale and triggers an explosive explosion. To prevent this, the pilot tubes come with an inbuilt cutoff valve.
A constant burning pilot light is not just dangerous but also wastes energy. Numerous studies have revealed that a pilot light can consume between $7 and $18 worth of gas each month. The wasted fuel also puts more strain on the air cooling system in summer. Pilot lights can attract spiders that can spin webs and clog up the pilot tubes. Finally, a constant flame can release trace amounts of the compound mercaptan, which creates the rotten egg smell found in natural gas. If you're ever worried about these issues, consider purchasing a gas fireplace with a remote control or replacing an old fireplace with a more efficient and modern-day model.
