Understanding Storage Gas Hot Water Systems

When it comes to home energy solutions, gas hot water systems are a popular choice. These systems use a gas burner and a heat exchanger to heat water on demand, offering energy efficiency and convenience. However, understanding how these systems work can be a bit tricky if you’re not familiar with the mechanics.

Upon further examination, two primary types of gas hot water systems emerge: storage and instantaneous models. Each has its unique characteristics and advantages, depending on your specific needs and circumstances. We’ll delve into the workings of these systems, highlighting the differences between storage and instantaneous models.

How a Gas Storage Hot Water Heater Works

Gas hot water systems heat water through a sensor-triggered gas burner and a heat exchanger. When you open a hot tap, the system springs into action, heating the water and delivering it through your pipes. The temperature of the water is regulated by an Electronic Control Unit (ECU) that controls ignition, gas flow, and safety aspects like automatic gas cut-off.

A storage gas water heater has a gas burner positioned beneath the storage tank. The water heats up at the bottom and rises to the top to be delivered through pipes when a tap is turned on. The temperature of the water is maintained hot at all times, controlled by an adjustable thermostat that triggers the main burner for consistent supply.

Storage vs. Instantaneous Models

A gas storage HWS is ideal for large households with high hot water demands. They can reheat a 170L tank within approximately an hour, making them a preferred choice for large families with substantial hot water requirements. However, they can suffer high heat loss in colder climates. In contrast, continuous hot water systems can provide a more energy-efficient solution for maintaining a steady supply of hot water.

On the other hand, continuous flow or instantaneous models, also known as continuous flow units, offer continuous flow hot water, ensuring:

Greater energy efficiency
Instantaneous water heating
Endless on-demand hot water, ensuring a steady supply
Compact size, highly beneficial for homes with limited space
Ability to handle higher flow rates than electric models

Selecting the Right Storage Gas Hot Water Heater for Your Home

Selecting an appropriate gas hot water system for your home is a vital step. Your selection should be based on factors such as:

Household size
Hot water usage
Available space
Overall costs

For instance, larger households with higher demands might benefit more from gas hot water storage systems, while smaller households may opt for tankless systems or smaller tanks.

Accurate assessment of your hot water needs and comparison of energy efficiency ratings are key to making an informed decision. We’ll provide insights on these aspects to aid your decision-making process.

Assessing Your Hot Water Needs

To estimate daily hot water usage, you can:

Monitor your household water meter over time
Use devices to measure the gallons per minute flow rate at faucets and showerheads
Time your water usage for bathing and dishwashing
Consider the gallons per minute used by appliances such as washing machines and dishwashers

The number of occupants in your home, along with identifying peak hot water usage times, can significantly determine the volume of hot water needed. Planning for future changes in your household, such as an increase in family members or additional fixtures, is also crucial. These considerations can help you determine if a larger hot water system will be required.

Comparing Energy Efficiency Ratings

Energy efficiency is a critical factor in choosing a gas hot water system. Here are some key points to consider:

A modern gas storage HWS typically has an energy rating of 6 Stars or better.

What are the specific professional installation requirements for these systems and how should regular servicing and maintenance be conducted? We’ll delve further into these matters.

Professional Installation Requirements

The installation of a gas hot water system is not a DIY job. A licensed gas fitter is required for installing these systems, and they should also be qualified to handle associated plumbing tasks. Professional plumbers can prevent installation errors such as improper soldering of fittings close to the tank or using incompatible metal pipes, which can lead to corrosion.

To avoid ‘dry firing’ and damaging the water heater, it’s also crucial to ensure the system is filled with water before powering it on after installation or maintenance work. Taking these precautions can help ensure the safety and longevity of your system.

Regular Servicing and Maintenance

Regular maintenance can significantly extend the lifespan of your gas hot water system. In fact, with proper care, some systems can last up to 12 years or more. However, gas hot water systems generally have higher maintenance requirements than solar hot water systems, primarily due to the gas burners and associated complex components.

Yearly inspections by a licensed plumber are crucial to ensure that all components of the system, including the heating element and operating unit, are functioning correctly. This can significantly reduce the likelihood of breakdowns and help achieve the upper end of the system’s lifespan, affecting the long-term value and frequency of replacement.

The Environmental Impact of Gas Hot Water Systems

While gas hot water systems are known for their efficiency and convenience, it’s important to consider their environmental impact. Gas storage hot water systems emit minimal greenhouse gases, positioning them as an eco-friendly option for home water heating. However, they do contribute to carbon emissions, which is a concern.

How do gas hot water systems measure against electric and solar options regarding environmental impact, and can solar compatibility boost their efficiency? We’ll investigate these queries.

Comparing Gas to Electric and Solar Options

When compared to electric heat pump and solar hot water systems, gas hot water systems generate higher greenhouse gas emissions. This is due to gas being a fossil fuel that is less environmentally friendly. Solar hot water systems significantly reduce carbon emissions by harnessing renewable solar energy, positioning them as one of the most environmentally friendly options.

Electric hot water systems, especially when powered by renewable energy sources like solar panels, also present significant environmental benefits. However, the source of energy for heating water is critical, with natural gas typically involving lower operational costs compared to electricity, compounding its popularity despite environmental concerns. It’s important to consider energy consumption when choosing between these hot water systems.

Enhancing Efficiency with Solar Compatibility

One way to enhance the energy efficiency of gas hot water systems is by combining them with a solar hot water system. Models like the Rinnai B26 and Rheem Hiline range are solar-compatible, providing the benefits of both gas and solar energy.

Adopting solar water heating systems can lead to substantial environmental benefits, such as preventing thousands of pounds of carbon dioxide emissions each year. However, their efficiency can be affected by factors such as climate, weather conditions, and the availability of sunlight.

Running Costs for A Gas Storage Water Heater

As a lot of our customers can attest to, gas storage hot water units while efficient are expensive to run. A retired couple can expect to spend between $400-$500pa on a storage system depending on brand and efficiency when connected to Natural gas and as much as $800pa when operating off LPG. A family of four can spend anywhere upto $1700pa to run an LPG 4-star unit and $1000pa for a Natural Gas Connection. When selecting an LPG hot water system optioning for the most efficient system available is ever more important.

See an example of how switching away from a conventional electric system can pay big long term.

Example. Common gas storage hot water system prices for installation especially in gated communities is the reticulated LPG with a Dux Forte 4-Star gas hot water system where you are stuck to the network operator with no competition. A couple in one of these communities can spend over $8500 over a ten-year period just on gas for their hot water alone. When the time comes for upgrading this unit to a modern more efficient heat pump hot water system even with no option for an off peak tariff or solar they could still cut this number down to under $2750 over a ten year period, a saving of nearly 70%.

Brands and Types of Gas Storage Hot Water Systems Available

We have all the best brands available with over 95% of our storage gas range available for same day installation including the bulletproof Rheem 4-Star range and the standard for Star storage the Steller 330. In our line up we also stock the best from Vulcan, Rinnai, Everhot, Dux and Thermann with the majority available in natural gas and LPG hot water system options. With massive range of systems available for same day install we will be sure to find the most suitable energy saving solution for your family.

The Efficiency of A Gas Storage Water Heater

No one like rising gas energy prices and just like electricity LPG and Natural Gas prices are sneaking up faster and faster. With you back pocket being hit hard its a good idea to make sure you select an appropriate sized system to suit your needs.

Not much has changed in the last few decades regarding the efficiency of gas hot water systems with most manufacturers sticking to the same blueprint across their ranges. With 4-Star being the minimum and standard for the majority of systems there are an increasing number of 5-star energy efficient units coming onto the market. The benefit of the extra star is in running costs with the average family saving around 10% in gas compared to a 4-star unit. The 5 star system does this by running the flue gas up through the middle of the unit then back down to loose as much heater as possible before existing the system.

Rebates for Gas Storage Hot Water Units

Currently in Queensland there are no rebates for a gas installation. Check with your supplier for promotions regarding new connections when switching to natural gas.

Warranties Available With Your Storage Gas Hot Water Systems

With decades of experience and minimal product changes you can expect a minimum 7 year cylinder warranty on all storage units with premium products getting 10 year as standard and 12 year warranties on stainless-steel cylinders. The majority of systems will have a 1-3 year component warranty depending on the effected part.

How To FindThe Right Gas Storage Hot Water System

With minimal differences in performance especially across the 4-Star range, no additonal features and standardised thermostats there is not much to seperate the range. Longevity has always been a strong point across all the main contenders excluding Rinnai which has recently released two systems. The majority of systems we replaced regardless of brand are over twenty years old with the exception of the Rheem Stellar 330 which is generally closer to 15.

When purchasing new gas hot water systems we would recommend focusing first on efficiency and especially any 5-Star systems and then basing your purchase on warranty as just becuase the units used to last 20+ years, we are sure the manufacturers would prefer that number dropped.

Important note is that while you may see a number of 5-Star units for sale they are not an option in a LPG hot water system due to the way the gas sinks in the burner chamber.

Is There a Better Option

Long term if you are wanting to stick with gas the higher rated energy efficiency the better off you will be. For those wishing to dramatically reduce the carbon footprint and hit to the back pocket a heat pump or solar hot water system is a great option. With a very similar plumbing arrangement only the additon of a new power circuit would be required to get rid of that gas bill for good.

Life Span of A Storage Gas Hot Water System

There isnt a genre of systems that have such consistancy scross brands for longevity. We replace the majority of systems close to 20 years out and we would hope to get atleast 15years with any new system regardless of warranty.

How Gas Storage Hot Water Systems Work

A storage gas hot water system is a common and reliable way to heat water for residential and commercial use. It operates by storing hot water in a tank and heating it using a gas burner, providing a continuous supply of hot water for use in the household.

The system consists of several components, including a gas burner, heat exchanger, water tank, thermostat, and pressure relief valve. The gas burner is typically fueled by natural gas or propane and heats up the heat exchanger. As water flows through the heat exchanger, it is heated by the heat exchange process and stored in the water tank for use.

The thermostat monitors the temperature of the water in the tank and activates the gas burner when the temperature drops below the desired level. Once the water is heated to the desired temperature, the thermostat switches off the gas burner to prevent overheating.

The pressure relief valve is another important component of the system. It regulates the pressure inside the water tank and releases excess pressure to prevent the tank from bursting. This ensures that the system operates safely and reliably.

One of the main advantages of a storage gas hot water system is its reliability. These systems provide a continuous supply of hot water and are not affected by fluctuations in gas supply or other external factors. They are also easy to install and require minimal maintenance, making them a cost-effective investment over the long term.

Another advantage of a storage gas hot water system is its flexibility. These systems are capable of storing large amounts of hot water, ensuring that there is always hot water available when needed. They also provide hot water at a consistent temperature, which is important for applications such as showers and baths.

In addition to their reliability and flexibility, storage gas hot water systems offer several other advantages. They are easy to operate and require minimal user intervention, making them a convenient solution for hot water. They also operate quietly and produce less noise compared to other water heating systems.

However, storage gas hot water systems do have some limitations. They are less energy efficient compared to other water heating systems, as they require energy to maintain the temperature of the water in the tank. They also have a larger footprint and take up more space compared to other systems, which may be a limiting factor for some homes or buildings.

FAQs

We would recommend when selecting a gas system to work off a tank capacity of 25L per person per day. While a standard system is only 135L they have a high reheat and recovery rate with most systems capable of reheating 200l/h.

A gas storage system with a family of four cost on average $1700pa when connected to LPG and $850pa for Natural Gas.

We would expect a well maintained, quality system to exceed 15 years of service.

You can expect to pay anywhere from $1650-$2200 for a 4-Star system and $2000-$2400 for a 5-Star system depending on brand and size

To install a hot water system for legal, performance and warranty requirements you will need to be a plumber with a restricted electrical license.
