Types of Hot Water Systems
Four primary types of hot water systems are prevalent in Australian households and businesses:
Gas Storage Hot Water Systems
A gas storage water heater heats water in an insulated tank, using natural gas or LPG as fuel. The heater maintains a reserve of hot water until it’s required. A system gas setup may be appropriate for your home if you have access to mains gas.
Electric Storage Hot Water Systems
Electric storage systems use heating elements whose energy consumption influences the long-term cost of hot water. While electric hot water systems are most efficient with off-peak tariffs and generally less efficient than gas, they serve as an alternative where gas connections are unavailable.
Heat pump water heaters use a heat exchange cycle to actively pump and heat water, drawing heat from the air into an existing hot water system’s storage tank. They are energy-efficient with a favourable price for hot water system operation, especially suitable in warmer climates.
Solar hot water systems utilise roof-mounted panels to heat your water, offering a sustainable solution for your home. Energy efficient, but rely on sufficient sunlight. Solar electric boosters may be added to cater to both home and business needs on cloudy days.
Gas Hot Water Systems
Continuous flow gas hot water system can provide instantaneous hot water with superior efficiency, making it a popular choice among Australians. Natural gas ignites to heat water stored in an insulated tank. When you turn on the hot tap, your system efficiently transitions from cold water to flowing heated water continuously to meet demand.
Gas hot water system installation costs average between $1,000 and $1,500, impacting your budget. Costs depend on the tank capacity, gas connection complexity, and if you need additional safety features. A licensed gasfitter must install your water heater to ensure safety and compliance.
Gas hot water is an effective choice to supply hot water for households with 2+ bathrooms. While maintenance costs remain low for this type of system, gas prices can affect operating expenses over time. Therefore when selecting a system, check the energy rating as higher efficiency translates to savings.
Electric Hot Water Systems
Electric storage units warm water in a tank using electric elements, an important consideration for energy efficiency. Pricing is quite affordable in the range of $450-$1,400 installed. Upfront purchase price depends on the tank size, power rating, and model features.
Electric hot water systems suit households with 1-2 bathrooms. They can work well when gas lines do not run to the property.
Just be mindful that using electric elements to heat water consumes more energy, making it less efficient than gas or solar options. The operating costs of an electric hot water system will affect the cost to your finances, influenced by electricity rates and the storage tank’s insulation quality.
One benefit of type hot water systems like electric storage tanks is the availability of off-peak controlled load tariffs. Should your hot water system qualify, more affordable overnight power rates could apply, assisting in the reduction of your ongoing bills. Considering electric units with an energy star rating between 3.5-4 stars is recommended for maximum efficiency.
Electric hot water systems present a straightforward, low-maintenance method to heat water. For optimal performance, ensure your storage tank is sized correctly and utilise off-peak power pricing.
Heat Pump Hot Water Systems
Heat pump water systems, frequently configured as split systems, offer energy efficiency leading to lower electricity bills. Split system heat pumps absorb heat from the surrounding air to heat water in a storage tank. An integrated system with inline plumbing can drive the process with a heat pump and fan.
Installation costs for a heat pump hot water system are around $3,000. Extra expenses may range between affordable to substantial, depending on the tank capacity required and the complexity of installation. As a specialised job, a licenced plumber is recommended.
Heat pump systems can run on electricity but provide instant hot energy output far exceeding the electrical energy they consume. This makes them much more efficient than conventional electric water heating methods. They can lower greenhouse emissions by up to 70% compared to traditional gas and electric systems, making them a green choice for your house.
One downside, which can affect performance, is that heat pumps are generally more effective in warmer climates. Their efficiency diminishes in temperatures below 5°C. Luckily most suburban areas even in cold Australian states see higher ambient temperatures regularly throughout the year.
Solar Hot Water Systems
Solar hot water systems represent a renewable energy option, and while the cost solar hot water units may be higher initially, they harness power from the sun to heat water. While the cost of installing a solar hot water system with its water tank ranges between $4,000 - $8,000 initially, the benefits to the environment and long-term savings are significant.
Solar heat is harnessed by roof-mounted solar collector panels that warm a transfer fluid within the solar hot water units. This solar heated liquid passes through a heat exchanger to warm water held in an insulated storage tank or pipes in the ground. When you turn on your hot water tap, the stored solar heated water is ready for use.
An advantage of solar hot water systems is the cost savings from free solar energy input once installed. Government rebates up to $1,000 are also available reducing payback periods. Using solar hot water systems can reduce greenhouse emissions by around 3 tonnes each year, enhancing sustainability.
Solar types hot water systems work well as pre-heaters to existing gas or electric systems.
Solar power could essentially eliminate energy bills, supplying abundant, renewable heat for your water needs independent of the grid.
Factors That Influence Installation Costs
When budgeting for a hot water system installation, there are several influential cost factors to consider beyond the unit purchase price. Its important to get the sizing right for your household to avoid unnecessary increases in the total expense.
Selecting the proper hot water system capacity for your property is essential. An undersized unit can lead to you run out hot water prematurely, ending up with uncomfortable lukewarm showers, whereas an oversized system leads to wastage of resources and funds. Consider:
- Number of bathrooms and residents
- Peak usage times
- Average hot water usage per day (litres)
Location and Access
The hot water system’s size and location, together with the ease of install, influence labour time and material requirements. More complex venting, drainage, gas or electrical connections add expenses. Outdoor units typically cost $200-$500 more in materials to weatherproof.
Safety Devices and Add-Ons
Ensuring your hot water system should include installing tempering valves, pressure limiting valves, and other safety features, all contributing to the final quoted price.
Licenced plumbers and technicians typically charge by the hour, forming a considerable part of the overall expense. Their hourly rates plus materials and transport eats into budgets. But their expertise ensures correct setup and safety.
Determining the Right Size and Capacity
Choosing the appropriate type hot water system size and capacity is crucial to seamlessly integrate into your household’s requirements without overspending. As a general rule, allow for 30-50 litres of hot water per person per day. For a family of 4, a 200 litre storage capacity would be suitable.
Consider peak demand times, such as morning showers and evening cleaning, when choosing the best hot water system for uninterrupted supply. Speaking with a reputable plumber can help assess your property’s needs based on:
- Number of bathrooms and residents
- Average and peak water usage in litres
- Allowance for future demand increases e.g. a growing family
Installing a system that’s too small can lead to lukewarm showers when demand spikes. Oversize systems are more expensive both upfront and ongoing as you heat more water than required. Getting the size right keeps costs in check while delivering sufficient hot water flow when you need it.
