When working out whether to get a gas or an electric water heating system installed, it is vital to do lots of research to find out how both systems work. Gas is a popular fuel to use to heat water and knowing the basics about how a gas heating system works is important and can be done by doing some research. However, it is important to avoid doing DIY plumbing work in order to repair a problem with a gas water heating system and instead it is much better to hire a professional to do the necessary work.
Understanding how a gas system works is fairly easy and it is good for a homeowner to learn about their heating systems in order to make it easier to spot a potential problem. Emergency gas hot water systems in Perth and in other large cities all over the world can be found through specialist plumbing companies and this is great to take advantage of if a problem occurs with the existing system, so that it is still possible to use hot water while the problem gets repaired.
Gas-Fuelled Water Heating Systems
A gas-fuelled water heating system works slightly differently to an electric-fuelled unit but the primary difference is what it is fuelled with, as opposed to how it runs.
Below are some of the main features of a gas-powered water heating system:
- They work with a thermostat that is usually made up of a copper tube that has a sensor made from mercury in the tip
- A gas water heating unit will have a special sensor known as a thermocouple
- This sensor senses whether or not the pilot light is lit
- When the pilot light is not lit, the sensor will prevent gas from being released
- When the pilot light is lit, gas will be allowed to flow to the burner through the valve
- A flame will then be lit that will heat the water from the bottom of the tank
- The cooler water will sink while the warmer water rises, making a natural circulation cycle
Anyone with an electric or a gas water heating system will know that a problem can occur at any time and that it is important to be able to contact a professional company to help in the event of an emergency. Emergency gas hot water offered by Plumbdog is an example of a company that can not only repair a problem with a heater but that can also provide a unit that can be used temporarily as a replacement for an interim period.
Top Tip: The temperature inside the tank is kept more uniform than many homeowners realise, as the heat rises through the central flue when it first goes through the tank and then the heat exits through a ventilation system. When the water in the tank gets to the desired temperature, the thermostat will instruct the gas control valve to shut off the flow of gas again.
