Gas vs Electric Hot Water Systems

At Mitchell Plumbing & Gas, we know that both gas and electric hot water systems offer different benefits for Brisbane homes. Gas hot water systems use natural gas or LPG to heat water, while electric hot water systems rely on electric heating elements. These hot water systems differ in several ways:

• Energy use and running costs
• Initial setup and installation costs
• How much upkeep they need
• How many years they last
• How quiet or noisy they are
• How fast they heat your water

‍

What Is a Gas Hot Water System?

A gas hot water system uses natural gas or LPG (Liquefied Petroleum Gas) as its heat source to warm up your water. When you need hot water, the hot water system pulls cold water into a tank where a gas burner heats it up.

The main parts that make up a gas hot water system are:

• The gas burner sits at the bottom of the tank and makes a flame that heats the water above it. This burner works with either natural gas from the mains or LPG from bottles.
• The storage tank is where your hot water stays until you need it. The tank has thick insulation to keep the water hot.
• The temperature control keeps your water at the right heat. It watches the water temperature and turns the burner on when the water gets too cold.

These hot water systems are found in many Brisbane homes and businesses. A gas hot water system can heat water quickly, which is good for busy households that use lots of hot water. Gas hot water systems work well in both small homes and large buildings because they come in different sizes to match how much hot water you need.

‍

What Is an Electric Hot Water System?

An electric hot water system uses electrical heating elements to warm up your water. When cold water enters the tank, electric elements turn energy into heat, much like how your kettle works but on a bigger scale. These hot water systems measure their power use in kilowatt-hours (kWh), which is what you see on your power bill.

The main parts of an electric hot water system include:

• The heating elements are metal rods that get hot when electricity flows through them. Most tanks have two elements - one at the top and one at the bottom - to heat water evenly.
• The storage tank holds your heated water and has thick insulation to keep the heat in. These tanks come in many sizes to suit different homes.
• The thermostat works like a switch that turns the elements on and off to keep your water at the right temperature. It makes sure you don't waste power heating water that's already hot enough.

In Brisbane homes and small shops, electric hot water systems are a common choice. They're straightforward to use and can fit in many spots around your property. Most homes connect them to off-peak power to save on running costs.

What Are The Differences Between Gas And Electric Hot Water Systems?

Gas and electric hot water systems each have their own strengths when it comes to running costs and how they work. Gas hot water systems often cost less to run because gas prices are usually lower than electricity rates. However, electric hot water systems can be cheaper to buy and install because they don't need gas pipes or flues.

When it comes to maintenance, electric hot water systems are simpler to look after because they have fewer moving parts. Gas hot water systems need regular checks of their gas connections and burners, but they often last longer - about 12-15 years compared to 8-12 years for electric hot water systems.

Gas hot water systems heat water faster and can keep up better when you're using lots of hot water. They take about 20-30 minutes to heat a full tank, while electric hot water systems might take 1-2 hours. As for noise, electric hot water systems are quieter because they don't have a burning flame like gas hot water systems do.

‍

Energy Consumption Differences Between Gas And Electric Hot Water Systems

At Mitchell Plumbing & Gas, we see that gas hot water systems in Brisbane homes use either natural gas from the mains or LPG from bottles to make heat. Electric hot water  systems, on the other hand, use power from the electricity grid to heat their elements.

When comparing energy use, gas hot water systems typically use less energy overall. A gas hot water system converts about 80% of its energy into heat, while electric hot water systems convert about 70% of their power into heat. This means gas hot water systems in Brisbane homes often have lower running costs, even though gas prices can change throughout the year.

‍

Installation Costs Differences Between Gas And Electric Hot Water Systems

Installation costs include everything needed to get your new hot water system up and running. This covers the price of the unit itself, all the parts needed, and the work to put it in.

Gas hot water systems often cost more to install at first because:

• They need special gas pipes and fittings
• They must have proper ventilation and flues
• A licensed gas fitter has to connect them
• Extra safety checks are needed

Electric hot water systems are usually simpler to install because:

• Most homes already have the right electrical connections
• They don't need extra ventilation
• They can go in more places around your home
• There's less safety equipment needed

In Brisbane homes, electric hot water system installation might cost between $800-1500, while gas hot water systems can range from $1200-2000. For businesses, costs are usually higher because of bigger hot water systems and more complex setups. Commercial electric installations might start at $2000, while commercial gas hot water systems could start at $2500 or more.

‍

Required Maintenance Differences Between Gas And Electric Hot Water Systems

Maintenance means keeping your hot water system working safely and efficiently through regular checks and upkeep. This helps prevent breakdowns and makes your hot water system last longer.

Gas hot water systems need more regular check-ups because they have more working parts:

• The gas burner needs yearly cleaning to work properly
• Gas lines must be checked for leaks regularly
• The flue and ventilation system need cleaning to stay clear
• Temperature and pressure valves need testing more often

Electric hot water systems are more straightforward to maintain:

• The heating elements usually only need checking if the water isn't hot
• The thermostat can work for years without problems
• The tank needs less frequent checks because there's no gas involved
• Pressure relief valves need checking once a year

‍

Average Lifespan Differences Between Gas And Electric Hot Water Systems

The lifespan of your hot water system is how long it will work well before it needs replacing. Both types of hot water systems can last many years when looked after properly.

Gas hot water systems typically last 10-15 years because:

• Their parts work harder with the constant flame
• Brisbane's weather can affect outdoor units
• The amount of hot water your family uses affects how long they last
• Salt air near the coast can make them age faster

Electric hot water systems often last between 10-20 years because:

• They have fewer moving parts that can wear out
• The heating elements can be replaced easily
• Water quality affects how long they last
• Regular use actually helps them last longer
• Indoor installation protects them from weather damage

The actual life of either hot water system depends on:

• How much hot water you use each day
• The water quality in your area
• Whether it's installed inside or outside
• How well it's maintained over the years

‍

Heat-up Time Differences Between Gas And Electric Hot Water Systems

Heat-up time is how long it takes for your hot water system to warm a full tank of cold water to the temperature you need. This matters when you've used up all your hot water and need more.

Gas hot water systems heat water much faster:

• A full tank heats up in about 30-40 minutes
• The gas flame provides instant, powerful heating
• Water at the bottom of the tank heats quickly
• The hot water system can keep heating while you're using hot water

Electric hot water systems take longer to heat water:

• A full tank needs about 1-2 hours to heat up
• The heating elements warm up gradually
• Water heats in layers from the bottom up
• Using hot water while it's heating slows the process down

‍

Noise Level Differences Between Gas And Electric Hot Water Systems

Noise level means how much sound your hot water system makes while it's working. This can be important if your hot water system is near bedrooms or living areas.

Gas hot water systems make more noise because:

• The gas burner makes a low rumbling sound at about 40-60 decibels
• You might hear clicking when the burner starts up
• The flame makes a constant background noise
• Air moving through the flue creates extra sound

Electric hot water systems are much quieter:

• They usually run at about 30-40 decibels
• You might hear a soft click when the elements turn on
• There's no flame or burning noise
• Most sounds are too quiet to notice
• The only noise is sometimes a gentle hum from the elements

‍
