Factors Driving Conversion Of Gas-Ducted Heating Systems Electric Heating Systems:
If you are a gas ducted heating system user considering replacing it with an electric heating system, you must do your research. Despite the technological advances, some people still prefer using the gas ducted systems.
Consider the following factors before making the conversion.
1. Energy Needs Assessment:
The first step in converting your gas-ducted heating to electric is to assess and evaluate your existing system. Consider factors such as whether it was able to meet your home’s temperature requirements. If yes, you’ll only need to find an electric heating system of similar power; otherwise, you need to do some strict assessment.
To find an appropriate electric heating system, you can determine your home’s energy needs using its size, insulation level, and heating requirements. Miscalculation can cause problems with your home’s heating comfort in the future. Our expert can do an energy needs assessment for you!
2. Cost Considerations:
Costing is among the most influential factors in converting gas-ducted heating to an eclectic system. Let’s take a holistic approach and assess all the costs of converting gas-ducted heating to an electric heating system. We will also discuss both systems’ operational, maintenance, and repair costs.
Upfront Costs:
Upfront or installation costs are the first price you’ll pay to get a heating system.
Gas ducted heating systems have higher upfront costs, ranging between $4000 and $11000, as they involve the price of heating units, ductwork, and all other related services. The prices may vary depending on the home’s size and the project’s complexity.
Electric heating systems have lower upfront costs, ranging between $2000 and $8000, and mostly require minimum plumbing work, except for under-the-floor heating systems.
Maintenance Costs:
Heating systems, like cooling systems, require regular maintenance. Experts recommend maintenance service at least once a year before the season starts to ensure optimum functionality.
In Melbourne, Australia, a gas ducted heating system’s maintenance costs range between $200 and $350. Due to ductwork, the cost is higher than for an electric system. The price may increase if the ductwork is complicated or the home is large. Maintenance charges will also increase if some parts require repair or replacement.
The maintenance cost for electric heating systems ranges from $150-$300. They don’t require much maintenance and can work perfectly without yearly maintenance services, too.
Energy Costs:
The energy cost determines the operational cost of the heating system. You can calculate it by multiplying the units consumed per unit of energy source cost.
Energy cost varies from home to home depending on its size, level of insulation, and consumption.
Gas Ducted Heating Cost:
The average gas consumption of a medium-sized home using a gas-ducted heating system is around 100 megajoules (MJ) per day. The consumption is higher for bigger, or poorly insulated homes.
The energy bill estimates for the gas ducted heating system concerning the home’s size are listed in the table below.
Home’s Size | Annual Estimated Energy Bill |
small house (~100m²) | $635 |
medium-sized house | $935 to $1,250 |
The energy bills for winter months are $80-$110 higher than usual due to increased consumption.
Prices also vary on the gas provider. Check rates with your supplier for more accurate energy cost estimates.
Electric Heating System Cost:
Depending on the electric heating system’s efficiency and the home’s size, an average Melbourne home consumes 2000 kWh to 5000 kWh annually for an electric heating system. Based on this average energy consumption, the average annual electricity cost for the electric heating system is approximately $600 to $1500.
The monthly electric heating costs of $50-$160 may peak up to $1300 during extreme cold days when energy requirements are higher.
You can control the electric energy bills by installing solar panels that utilise sunlight to generate energy, drastically decreasing the energy bills.
Long Term Savings:
Long-term savings depend on a heating system’s average lifespan. Often, longevity takes the lead over installation, maintenance, and energy costs, providing homeowners with savings and comfort.
A typical gas-ducted heating system may last 15-20 years, whereas an electric system may last 20-30 years. Electric systems with lower maintenance and a longer lifespan overcome their slightly higher energy costs and are great value for money.
3. Electric Heating Options Available In The Market:
Melbourne experiences cold weather, with average temperatures of 6.5 – 14.2°C (43.7 – 57.6°F). The winds are chilly, and a heating system is a must to survive them.
There are many advanced electric heating options readily available in the market. Explore each option, checking its energy star rating, energy consumption, and other factors to get the best one for your home.
Heat Pumps and Reverse Cycle Systems:
This electric heating system provides centralized heating and cooling, providing thermal comfort all year. They are a good fit for Melbourne’s changing weather.
Electric Wall and Panel Heaters:
Electric wall and panel heaters are a good option for small spaces. They are portable and can be moved anywhere in the home for heating specific areas.
Electric Ducted Heating:
Like gas-ducted heating, electric ducted heating uses ducts to circulate warm air into the living spaces. This electric heating system is quite common in Melbourne homes as they provide efficient, and centralised heating for the whole home.
Electric Broilers:
Electric boilers are comfortable, quiet, and efficient. When combined with underfloor heating and towel rails, they are good for temperature control.
4. Compatibility With The Infrastructure:
Converting gas ducted heating to electric requires that the new system be compatible with your home’s plumbing and electric work. A new system can integrate and work without going over the mile or spending a lot of money on installation.
5. Electrical Capacity:
Old Victorian homes have an electrical capacity of 60-120 amps, which isn’t enough to handle an electric heating system. Check if your home can handle the additional load and has dedicated circuits that support high power usage. Ensure wiring is up to code and capable of supporting the increased electric load.
6. Environmental Considerations:
It’s a mutual responsibility to take care of our mother earth. We must be conscious and choose environmentally friendly options that have zero or minimum carbon imprint. Gas is a nonrenewable, limited natural resource that creates a higher carbon imprint than electric heating systems.
Although electric heating systems have zero carbon imprint at the point of use, they may have an environmental impact at the back end. If electricity is made using non-renewable resources, it is harmful to the environment.
Electric heating systems are more efficient and have less energy wastage which makes them an environmentally friendly option.
7. Maintenance And Repair Services:
Maintenance and repair cost is one factor while another factor to consider is availability of service provider and spare parts for repair. Before investing in an electric heating system always check if maintenance and repair services are available in your area.
8. Consider System Efficiency:
Always check the energy consumption details mentioned on the package insert of the heating system to calculate the system’s efficiency.
Generally, the advanced electric heating systems are more energy efficient then gas ducted heating systems especially if paired with solar panels. This efficiency attracts homeowners in order to reduce their energy bills and overall operational costs.
9. Regulatory Compliances With Building:
The Victorian Building Authority publishes a National Construction Code (NCC) for heating systems in Melbourne. You must refer to the NCC 2024 update to get the latest information about regulatory compliances.
NCC sets clear rules and regulations for local buildings that are essential to follow in new constructions and renovations to meet sustainability goals and achieve energy efficiency targets. Their regulations outline requirements for the design, installation, and maintenance of mechanical heating systems to ensure energy efficiency and proper functioning so home occupants can enjoy thermal comfort without wasting energy.
The codes also include rules for safety, environmental protection, home insulation and other elements.
10. Future Proofing Home:
With advancements in heating technology, you should consider installing systems that can integrate with smart technologies and sustainable solutions. Electric heating systems are more futuristic and align with future energy trends.
The above-stated factors are essential to consider for a smooth and successful transition.
