Choosing the Right Ducted Heating System for Your Home

Choosing a heating system is crucial for your comfort and long-term energy costs. Joniec Plumbing offers expert advice and professional installations, ensuring you get the right ducted heating system tailored to your home and lifestyle.

Electric Ducted Reverse-Cycle Air Conditioning

Electric ducted reverse-cycle air conditioning efficiently provides both heating and cooling through ducts connected to a central indoor unit and an outdoor compressor. It operates by extracting heat from outdoor air and distributing it throughout your home.

Key Advantages:

  • Efficient and Versatile: Provides both heating and cooling from a single system.
  • Energy Savings: Utilises heat pump technology, making it more efficient than traditional electric heaters.
  • Zoning Capability: Divide your home into zones to only heat rooms that are in use, significantly lowering energy bills.
  • Improved Air Quality: Regular maintenance ensures better indoor air quality through clean air circulation.

Considerations:

  • Initial Cost: Higher upfront installation costs compared to smaller, individual room systems.
  • Noise: External compressor units may produce noise, potentially impacting neighbours and subject to local council regulations.
  • Ductwork Efficiency: Energy loss through ducts can decrease efficiency compared to ductless systems, particularly if duct insulation is inadequate.
  • Power Requirements: Larger systems may require switchboard upgrades or three-phase power, increasing installation costs.

Buying and Installation Tips:

  • Compressor Type: Opt for a variable-speed (inverter) compressor for quieter operation and lower ongoing costs compared to standard compressors.
  • Ductwork Insulation: Ensure ducts have a high R-value insulation rating, minimising heat losses and improving efficiency.
  • Zoned Energy Ratings: Ask about the system’s Zoned Energy Rating, indicating energy efficiency and operating cost savings.
  • System Sizing: Accurately size the system to your home’s requirements to avoid inefficiencies and higher running costs.

Gas Ducted Heating Systems

Gas ducted heating systems offer rapid warmth by drawing air into a gas furnace and distributing heated air through ductwork. It is a widely-used heating solution in many Victorian homes, known for quick and effective heating capabilities.

Key Advantages:

  • Fast Heating: Quickly heats your home, ideal for colder climates.
  • Zoning Options: Some systems allow different zones with individual thermostats, efficiently heating specific areas as needed.
  • Reliable Performance: Proven technology providing consistent and reliable heating.

Considerations:

  • Operating Costs: Higher ongoing costs than electric reverse-cycle systems due to gas and electricity consumption for fan operation.
  • Cooling Separate: Requires an additional system if cooling is needed, increasing installation and maintenance costs.
  • Energy Loss: Potential for significant heat loss through ductwork if poorly insulated or aged.
  • Environmental Impact: Higher greenhouse gas emissions compared to electric systems, especially if running on LPG.

Buying and Installation Tips:

  • Energy Ratings: Select systems with higher star ratings (5 stars or above) for long-term cost savings.
  • Ductwork Insulation: Choose ductwork with high R-value insulation to minimise energy losses and improve efficiency.
  • Zoning Capabilities: Systems with advanced zoning provide greater flexibility and efficiency, reducing unnecessary heating in unused rooms.
  • Regular Maintenance: Ensure regular servicing of the furnace every two years to maintain safe and efficient operation.

Efficiency and Maintenance Guidelines for Both Systems

Regardless of the system chosen, proper usage and regular maintenance are essential for achieving optimal efficiency:

  • Thermostat Settings: Set thermostats between 18°C and 20°C. Each additional degree can increase heating bills by approximately 15%.
  • Regular Cleaning: Monthly cleaning of air filters ensures your system runs efficiently and maintains good indoor air quality.
  • Professional Servicing: Follow manufacturer recommendations for regular servicing to extend system lifespan and maintain optimal efficiency.

Choosing the Right hot water System for Your Home

The right hot water system choice affects your comfort and long-term energy expenses. Joniec Plumbing delivers expert consultation and professional installations, ensuring you get the most suitable solution for your property and usage patterns.

Gas Hot Water Systems

Gas hot water systems have long been a trusted option for households with access to natural gas. These systems are known for their quick recovery times and relatively low running costs compared to older electric systems. There are two primary types:

1. Gas Storage Systems

These systems heat and store water in an insulated tank. Hot water is drawn from the top of the tank while cold water enters at the bottom, triggering the burner when hot water is used.

  • Rated between 4 and 5.3 stars for energy efficiency.
  • Heat losses occur even when no water is being used (standby losses).
  • Best suited for households with steady daily hot water use.
  • Simple replacement option for existing gas storage systems.

2. Gas Instantaneous (Continuous Flow) Systems

These systems heat water only when it’s needed. As water flows through the unit, it passes over a gas burner that heats it in real-time.

  • Rated between 5 and 6 stars; some systems reach 7-star equivalent.
  • Highly efficient—no heat loss from stored water.
  • May require a gas line upgrade to handle higher flow rates.
  • Perfect for households with intermittent or low water usage.

Comparing Costs and Efficiency

  • Gas prices are expected to rise over time—consider this in long-term planning.
  • Instantaneous units typically cost less to run over the year than gas storage systems.
  • Check the Gas Energy Rating Label: more stars = better efficiency and lower bills.
  • 200 litres/day is used as a benchmark, but most households now average 120–130L daily.

Rebates and Upgrades

  • Eligible homeowners may receive discounts under the Victorian Energy Upgrades scheme.
  • Gas water heaters can be replaced with gas-boosted solar systems for improved efficiency.
  • Some systems are eligible for a 50% rebate up to $1,000 through Solar Victoria.

Electric Hot Water Systems

Electric systems are common in Victorian homes, especially in apartments and older properties. They’re available as both storage and instantaneous models, with some designed to run on off-peak tariffs to reduce operating costs. While they’re the cheapest to install, they can be among the most expensive to operate without solar or heat pump integration.

1. Electric Storage Systems

These systems heat water using an electric element and store it in an insulated tank, usually ranging from 25L to 400L.

  • Simple design and affordable installation.
  • Available as main-pressure or gravity-fed systems.
  • Large systems can be run on off-peak tariffs to reduce costs.
  • Some models include a boost element for extra heating if needed.
  • Heat loss (standing loss) occurs through tank walls, especially in oversized systems.

2. Electric Instantaneous Systems

These units use a powerful element to heat water on demand, without the need for a storage tank.

  • Efficient for small households or low-demand applications.
  • Eliminate heat losses from storage.
  • Operate on peak tariffs, making them costlier without solar backup.
  • Need careful sizing to avoid insufficient supply during high demand.

Improving Performance and Efficiency

  • Use with solar PV systems to maximise savings—heat water during the day when solar is available.
  • Solar diverters can redirect excess solar energy to heat water, reducing grid electricity usage.
  • Consider heat pump or solar-boosted electric systems for improved performance and long-term savings.

Rebates and Upgrades

  • Government incentives available to upgrade to electric boosted solar, heat pump or high-efficiency systems.
  • Solar Victoria rebate available up to $1,000 for eligible households installing solar or heat pump hot water.
  • Victorian Energy Upgrades scheme provides additional discounts on approved systems.

Solar Hot Water Systems

Solar hot water systems are a smart and sustainable choice for homeowners looking to lower long-term energy bills and reduce carbon emissions. They use roof-mounted solar collectors to absorb the sun’s energy and heat water, which is then stored in a tank for household use. These systems are often paired with a gas or electric booster to ensure hot water supply during cloudy periods.

Key Benefits

  • Significantly lower running costs, especially when combined with rooftop solar PV.
  • Environmentally friendly—reduces reliance on fossil fuels and lowers household emissions.
  • Boosters ensure reliable performance in winter or poor weather conditions.
  • Long-term savings on energy bills can offset higher upfront installation costs.

Considerations

  • Initial installation is more expensive compared to traditional gas or electric systems.
  • Boosting may rely on gas or electricity during colder months.
  • Roof space is required for solar collectors—this may compete with solar PV placement.
  • Best suited to households with moderate to high hot water usage.

Government Support

  • Eligible for Solar Victoria rebates up to $1,000 depending on income and system type.
  • Victorian Energy Upgrades may offer discounts for approved solar hot water systems.
  • Additional incentives available for replacing inefficient gas or electric systems with solar models.

Key Considerations When Choosing a System

  • Household Size: Larger households need more capacity; smaller households benefit from efficiency over volume.
  • Hot Water Usage: Instantaneous systems suit occasional use, while storage suits frequent demand.
  • Tariffs: Off-peak electricity tariffs offer lower running costs for storage units.
  • Space: Storage tanks need space; instantaneous units are compact and wall-mounted.
  • Energy Source: Choose based on access to natural gas or solar PV systems.
  • Installation Costs vs Long-Term Savings: Higher upfront costs for efficient systems often mean long-term savings.
