If you're looking to cozy up in the cold outdoors with a propane patio heater, it's important to know how to properly use the appliance. Matthew Griffith, chief of the prevention division at Montreal's Fire Department, says that shoppers should look for products that have safety certifications.

The patio heater must be properly attached and there shouldn't be combustible material nearby.

Pressure Regulator

Gas regulators are essentially mechanical devices that we use in our cars and homes every day without even giving them a second thought. Their invention, 135 years ago, revolutionized the way propane and natural gas are used for heating, cooking and welding with oxy-fuel. The fundamental purpose of regulators is the same, but there are numerous variations. The regulator uses an element that senses pressure, usually a fabric-reinforced dialythm, to control a valve's position and restrict the flow of gas for patio heater.

The diaphragm joins the stem of the valve using rod that runs through the set spring and diaphragm, then into the valve. This mechanism senses the gas pressure inside the house or pipeline and adjusts the valve plug's position to match the demand. As the use of gas in the house decreases the pressure between the regulator and the house reduces too. This causes the diaphragm of the regulator to shrink downwards, and it moves the valve plug closer to the orifice, which limits flow. As the demand for gas grows in the home the valve will open more, thereby increasing the flow.

The valve plug remains closed until the demand for the house decreases. This opens the valve to increase the flow. This process is referred to as sizing and it is the primary function of the regulator.

As the valve opens the pressure builds up in the main chamber which is connected to the outlet port of the hose via a venturi tube. The pressure can be adjusted by adjusting the handle or screw located on the outside regulator. When the screw is rotated counterclockwise, it raises the pressure. When it is turned clockwise, it decreases the pressure.

When selecting a pressure regulator be aware that the minimum and maximum nominal pressures are established by commercial standards, and not the pressure at the supply line. The regulator must be compatible with the hose you are using. Find a hose marked whistle-free. It should feature alternating rings that are different sizes. This will prevent resonance noises from forming across the length.

Thermocouple

Thermocouples operate on the premise that metals of different composition in contact at their ends can generate a voltage, even if they are at wildly different temperatures. They are used to determine the temperature differences between two points in a system and convert this data into an electrical signal that can then be read by thermocouple meter or another instrument. Thermocouples possess several advantages over more common sensors like thermistors, which include the ability to detect extremely high temperatures and operate in environments that are corrosive.

The measuring (or hot) junction is created by connecting two metals with different properties at one end, while at the other, the reference (or cold) junction, is maintained at an unchanging temperature. Thermocouples operate as passive devices, which means they don't require power in order to function. The voltage generated is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers as well as metrology standards organizations like 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 exposed type of junction is a bit higher than the protective sheath, and provides the fastest response. In the event of measurements under corrosive conditions it is recommended that a grounded thermocouple be used. A welded wire thermocouple is physically insulated from the sheath by mgO powder to prevent penetration of gas or moisture that could lead to errors.

The welded wire thermocouple is also a benefit in being more vibration resistant. It is recommended to use in harsh environments and at pressures as high as 3000 psi. A thermocouple that is damaged is usually caused by a lack in polarity. If the sheath is not correctly polarized, both ends of the thermocouple be in a state of discordant voltages at the junction of measurement which could result in an inaccurate reading and even end up damaging the instrument. A sensor that is not properly calibrated or placed in the right place can cause a malfunctioning thermocouple.

Thermostat

Gas patio heater gas cylinder heaters, unlike electric heaters that are wired to the wall are portable and operate on propane or natural gas. Thermostats regulate the flow energy into these cylinders to ensure that they do not overflow, but they still provide warmth when required. The thermostat detects the temperature of air passing over it. The thermostat also determines if the room is cooling down to a comfortable temperature and switches the heating off.

The most popular type of thermostat is a digital one. It uses a microcontroller that converts a fluctuating electrical resistance into a reading of temperature. It is able to do this more accurately than previous mercury switch thermostats, which utilized a mercury coil with three wires that would change according to temperature. This allowed it to tilt a mercury switch that was connected to the electrical circuit of the air conditioning or heater unit, and turn it on or off.

A mechanical thermostat is a different kind. The thermostat is opened when the wax in the small gas patio heater cylinder begins to melt, which is approximately 180 degrees F. (Different thermostats have different opening temperatures). A rod connected to the valve is then pressed into the 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, closing the valve.

You can also program thermostats to alter the temperature at various times during the day. You can reduce energy usage by setting your heating to turn on and off while you are working, or sleeping, instead of being on all the time. You can also set your thermostat to turn on sooner so that you can get home to a comfortable temperature. Thermostats usually have a feature called a heat anticipator, which prevents the heater from turning on too early. This is because different parts of the house often attain the temperature set before the thermostat does.

Pilot Light

Although many modern heating and homes have eliminated pilot lights, older homes and furnaces still use them to light gas in the chamber for burning. It's essential to know how to safely to relight the pilot light in case it ever fails.

A pilot light creates tiny flames that heat a thermocouple, which generates electricity and holds the outdoor gas patio heater valve open. If the pilot flame dies the thermocouple cools and ceases to produce electricity, thereby closing the gas valve. Pilot lights are used in the majority of propane and natural appliances, such as fireplaces, water heaters, furnaces, ranges, barbecues and hot tubs.

The process of lighting a pilot light requires that you first turn off the best gas patio heater uk valve at the appliance. Then, you have to take out any doors or panels that might hinder getting to the pilot light. Follow the instructions on the front to open the tube for the pilot light. After you've re-lit your pilot light, turn the gas valve knob to the "on" position.

Safety is the primary reason to keep a pilot light on. If you accidentally turn off the pilot light, the gas that is constantly escaping from the tube could build up in your house until the spark or static electricity ignites the gas and causes an explosive explosion. Pilot tubes are designed to include an inbuilt cutoff valve to prevent this from happening.

Apart from the safety concerns the burning of a pilot light also wastes considerable energy. A pilot light can burn between $7 to $18 worth of gas each month, according to numerous studies. This waste of fuel also puts a heavier load on the air conditioning system during summer use. A pilot light may attract spiders which can spin webs, and clog the pilot tubes. Finally, a constant flame can emit trace amounts of the mercaptan compound that produces the rotten egg smell found in natural gas. If you're worried about these issues, think about buying a remote controlled gas fire or replacing your old fireplace with a more modern, efficient model.
