Whether you’re considering upgrading to a gas storage hot water system, or you’re just eager to know more about how gas powers your showers, we hope to help you understand what’s happening behind the scenes every time you turn on your tap.
By the end, we hope you’ll leave with a clear picture of how your gas hot water system operates.
What is a Gas Hot Water System?
For starters, we will try to answer “How does gas hot water work?” question in the most simple way possible.
Note that there are several types of hot water systems, but gas-powered systems are so well known for their fast-heating ability and energy-efficiency!
Sounds like something you might want to know more about, right?
In essence, a gas storage hot water system is a unit that heats water using natural gas or LPG (liquefied petroleum gas) as the main energy source.
For many homes within an area that is readily available for natural gas, this type of hot water system can be such a cost-effective solution. Plus, with regular maintenance, it can extend the lifespan of hot water systems.
Another popular type is electric water heaters. However, they are known to take more time to heat water than gas-powered ones. So, if you prefer to not wait too long for that hot shower, you can opt for the latter!
How Do Gas Hot Water Systems Work?
Now that you have a better idea of what a gas hot water system is, let’s take a closer look at how it actually operates.
As mentioned earlier, a gas hot water system uses natural gas or LPG as its fuel source.
We’re going to break it down to help you visualise what happens every time you turn on your hot water tap. Regardless of the type, gas hot water systems generally operate using the same basic principles.
A gas storage hot water system operates using a gas burner located beneath the storage tank.
When cold water enters the tank, it naturally sinks to the bottom, where the burner heats it up.
As the water warms, it rises to the top, ready to be delivered through your pipes as soon as you turn on the hot water tap.
This cycle ensures that you always have a supply of hot water when you need it.
At the heart of the system is a thermostat that carefully regulates the water’s temperature.
The gas burner and heating elements work together to keep the water at a consistent and safe temperature. According to regulations, the stored water must not drop below 60°C to prevent the growth of harmful bacteria.
Designed with safety in mind, your gas hot water system comes with a valve to balance the pressure and reduce the damage risk.
As the water heats up and expands, it can cause an increase in the tank’s pressure. This is where a pressure relief valve comes into play. The valve will open to release excess water through the overflow pipe to keep the tank from becoming over-pressurised.
One key feature of a gas storage system is the flue that allows the hot air and fumes produced by gas combustion to safely escape the system.
It is a pipe that runs through the middle of the tank. Moreover, it also helps maintain a safe environment by venting harmful gases outside. So, you’ll get a water heater that runs efficiently and safely!
What are the Advantages and Disadvantages of Gas Hot Water Systems?
So far, gas hot water systems seem like a fantastic option, but like everything else, they come with their own pros and cons.
Before making any decisions, it’s important to weigh the advantages and disadvantages of having a gas-powered system in your home.
Advantages
- Faster Heating. One of the biggest advantages of gas systems is their speed! They typically heat up within 30 to 60 minutes, depending on the tank size.
- Energy Efficiency. If you already have access to the gas main. It is likely that opting for gas appliances is a lot more affordable in the long run.
- Reliable in Power Outages. You come home to a power outage and it’s cold outside? Fret not, you can still enjoy a hot shower – just when you need it most.
Disadvantages
- Upfront Costs. You may have to pay a lot of money for the initial installation cost, which may include the cost of installing gas lines if it’s not readily available at your home. It’s an investment, but one that can pay off over time with savings on energy bills.
- Maintenance. While gas systems are generally reliable, they do require more maintenance than electric systems. Keeping up with hot water system maintenance is key to preventing breakdowns, so be prepared for some regular upkeep to keep your system running smoothly.
- Ventilation Requirements. To safely expel the byproducts of combustion, you’ll need to make sure there’s a venting system in place prior to installing a gas hot water system
