HEAT PUMP HOT WATER SUPPLY & INSTALLATION
Energy Saver is an initiative proudly funded by the NSW Government 1. Operation and Functionality
Traditional Storage Tank Systems
Traditional storage tank water heaters have an insulated tank that holds and stores a set amount of hot water. The tank usually has a size between 40-80 gallons.
Cold water enters the tank, where either gas burners or electric heating elements heat it. The heated water is stored in the tank, ready for use. These units continually heat and reheat water in the tank even when hot water is not being used.
Tankless Hot Water Systems
As the name suggests, tankless water heaters do not have a storage tank. Instead, they employ a heating device that only activates when hot water is needed. Cold water travels through a heat exchanger, rapidly heating on demand. Once the tap is turned off, the unit shuts off heating.
This eliminates the energy wasted by keeping a tank of water hot 24/7. Tankless systems can provide a constant supply of hot water if they are properly sized to meet the hot water demands.
2. Energy Efficiency
Traditional Storage Tank Systems
The energy efficiency of traditional tank water heaters have improved over the last years but in general they lose some heat over time since they constantly need to maintain water at a preset temperature. Older models can have significant standby heat losses through the tank walls and piping.
Tankless models, on the other hand, are at an advantage since they do not store hot water, so they avoid these standby energy losses.
Factors like insulation and tank size impact efficiency since larger tanks and better insulation reduce standby losses. However, oversizing the tank leads to more overall heat loss. Proper installation also has an effect on the efficiency.
Tankless Hot Water Systems
The on-demand operation and the lack of a storage tank give tankless water heaters a clear efficiency advantage. The energy consumed is almost completely used for heating the water needed. Tankless heaters can operate with efficiency ratings over 90%, however, proper sizing is crucial.
Units that are undersized compared to the hot water demand will operate inefficiently, as they will heat cooler incoming water to higher temperatures quickly.
Oversized units that experience frequent start-stop operation could be more efficient. So, maximizing efficiency requires accurate demand calculation during sizing.
3. Space Requirements
Traditional Storage Tank Systems
Traditional tank water heaters are bulky, requiring a significant portion of floor space. Storage tanks can hold between 20 and 80+ gallons of water and their size depends on household size, daily hot water usage, and peak demand.
More family members in the household means a higher hot water demand and therefore a larger tank and larger unit size. These types of heaters are often installed in garages, utility rooms, or basements that can accommodate the space needs.
Tankless Hot Water Systems
One major advantage tankless water heaters have over traditional systems is their compact size since no water storage tank is needed. Most residential tankless heaters take up the size of a small briefcase or carry-on bag.
They can often be mounted directly on walls since they only require simple inlet and outlet pipes and an electrical outlety. This frees up substantial floor space for other uses. Their small size also offers more flexibility to install the units closer to hot water usage points.
4. Lifespan and Maintenance
Traditional Storage Tank Systems
On average, storage tank water heaters last 8-12 years before requiring replacement. Water mineral buildup and sediment that collects in the tanks degrade its efficiency over time. This buildup coats the heating elements and tank walls which reduces heat transfer.
Over time, the accumulation of this buildup can lead to element failure or tank leaks/corrosion requiring early replacement.
Frequent maintenance is required to prevent this damage. Annual draining and flushing remove some mineral deposits and extend their lifespan, and some heating elements need to be replaced, as well as anodes, and other components.
Tankless Hot Water Systems
High quality tankless heaters are designed to last over 20 years, and some manufacturers offer up to 25 years of warranties. Their long lifetime is mainly due to their simple on-demand design.
Mineral deposits do not accumulate significantly in the heat exchanger to significantly reduce efficiency, and heat exchangers last longer without constantly heating standing water.
Maintenance procedures involve removing small mineral deposits by flushing the heat exchanger occasionally (every 2-3 years). The simple components and absence of leaks from a water tank also result in a longer lifespan compared to traditional systems.
5. Water Supply Capacity
Traditional Storage Tank Systems
Traditional tank water heaters can supply hot water continuously with good recovery rates between hot water draws. Multiple taps can be simultaneously accessed as the entire hot water storage is accessible.
Gas heaters, in particular, can supply a high volume of hot water for longer periods for high-intensity purposes such as filling a tub.
However, tank capacities under 50 gallons may run out of hot water when too many taps are used at once for a long time. Systems sized at over 50 gallons provide adequate hot water, even for larger households, provided the heating elements/burners are adequately sized.
Tankless Hot Water Systems
Tankless water heaters produce unlimited hot water on demand. However, most residential units have maximum flow rates below 10 gallons/minute (depending on model and heating technology).
This is usually sufficient for two taps, like a shower and sink. However, if there are more units drawing hot water at the same time or if there are high-flow appliances like bathtub fillers, the consumption may exceed the heater’s capacity, resulting in decreased water output temperature.
Larger commercial tankless heaters have higher maximum flow rates for managing the hot water demands to accommodate for larger facilities.
For households, tankless electric models can supply more hot water than similarly sized gas models. Appropriately sizing units for the household demand is key to ensure adequate hot water capacity.
Conclusion
Both traditional storage tank systems and tankless water heating systems have a number of advantages and disadvantages. Traditional systems are simple to install and use and are suitable for low to mid-hot water demand spaces.
Tankless heaters are extremely efficient, durable, and compact but require accurate demand calculation and sizing.
Traditional heaters may be the most cost-effective option for households with low hot water usage or single taps running at a time.
Homes with higher demands, simultaneous water draws, or space constraints may benefit more from tankless systems in the long run despite their higher upfront costs. Carefully matching the system’s capabilities to current and future needs is key to making the right choice.

Upgrade Your Water Heating: Rebates Await!
HEAT PUMP HOT WATER SUPPLY & INSTALLATION
Energy Saver is an initiative proudly funded by the NSW Government Upgrading from a traditional storage tank water heater to a tankless model comes with many benefits.
Tankless water heaters, otherwise known as on-demand or instantaneous water heaters, have become increasingly popular as an energy-efficient and space-saving alternative in recent years.
Here are 7 key advantages you can expect from making the switch:
1. Endless Hot Water
The major benefit of going tankless is the unlimited supply of hot water. Tankless heaters provide hot water directly from the water mains when it’s needed, rather than heating and storing a tank full of water in advance.
This means you’ll always have hot water, even for long showers, filling the tub, running the dishwasher and washing machine simultaneously, or when several people need hot water at once.
The consistent hot water supply makes tankless units ideal for larger families and homes with busy mornings getting kids ready for school while parents are preparing for work.
The simultaneous hot water demands would strain a storage tank heater, resulting in weak water pressure or cold water when the tank runs dry. But with a properly sized tankless heater based on your peak demand, you may finally have enough hot water for those early morning routines.
You’ll also have peace of mind hosting holiday gatherings with extra house guests or big parties with lots of dishes to wash. The endless supply keeps sinks, tubs, and showers primed with piping-hot water, no matter the competing demands.
2. Energy Savings
Tankless water heaters only heat water as needed, rather than maintaining it at a high temperature in a storage tank with standby heat losses through the insulated walls.
This results in increased efficiency and significant energy savings compared to traditional tank heaters.
Homeowners can expect up to 34% natural gas savings by upgrading to ENERGY STAR-rated tankless systems. For electric tankless models, energy savings range from 24% to 34%, according to Department of Energy studies.
These numbers account for both the efficiency gains and standby losses avoided. Based on the national average energy costs, you may save over $300 yearly on electric or gas bills depending on the fuel type.
The energy savings come from both the technology and the sized-for-demand approach. Tankless heaters utilize advanced heat exchangers that extract over 90% of the fuel’s heat input using highly conductive metals.
Burners and heating elements only fire when hot water is needed, thereby reducing waste.
3. Space Saving
Eliminating the large storage tank frees up valuable floor space in your utility closet, laundry room, or basement.
Tankless water heaters are ultra-compact, usually no larger than carry-on luggage tucked up on the wall. Condensing tankless models that recapture additional heat are only slightly larger.
The minimal footprint keeps utility and storage rooms free rather than being cramped by obtrusive tank heaters. Space savings over a 50-gallon standard tank are over 16 square feet – like the size of a hallway closet.
For buyers and renters in smaller homes like apartments and condos, the recovered space makes going tankless an easy choice to keep rooms less cluttered.
4. Longer Lifespan
Another advantage of the tankless design is exceptional durability, with a lifespan ranging from 15-25 years or more. That’s at least twice as long as functional lifespan of an average traditional tank water heater. Properly maintained units can sometimes last 30 years.
Without a bulky tank constantly exposed to heated water, tankless systems avoid internal corrosion and mineral scale buildup that leads to tank failures.
Fewer mechanical components and innovative near-commercial grade heat exchangers also increase reliability and limit costly repairs down the road.
The long lifespan reduces the hassle and expense of draining, removing, and replacing worn-out water heating tanks. One tankless unit can outlive 2-3 standard models over its lifetime.
5. High Flow Rates
Tankless water heaters can have very high flow rates, heating water on demand faster than storage tanks can deliver. The continuous full-capacity operation means consistent temperatures and excellent water pressure reaching fixtures.
There’s no fluctuation or weakening flows as you tap into previously heated reserves like with tank heaters.
Higher-end gas tankless models provide up to 10 gallons per minute (GPM) – enough hot water for two or more demands simultaneously. Electric tankless offerings may supply over 6 GPM reliably.
Upgrading to a tankless unit properly sized for your typical peak hot water draws enables enjoyable high-flow showers and faster sink fills without the frustrating fluctuations of tank heaters.
The endless hot water may also allow you to adjust your household plumbing system by removing low-flow or throttling restrictions previously installed to conserve hot water reserves.
Removing flow restrictors provides full-pressure satisfaction at all fixtures.
6. Environmentally Friendly
The energy efficiency, long lifespan, and low standby losses of tankless water heaters make them a more environmentally responsible option compared to storage tank models. Conserving electricity or gas carries considerable eco-benefits as it:
- Reduces air pollution and greenhouse gases emanating from power generation
- Conserves natural gas supplies and reduces dependence on fossil fuels
- Avoids water pollution and ecosystem risks from energy production
- Cuts resource harvesting and transport from reduced energy demands
Tankless models also conserve water by eliminating the need to bleed taps and showerheads while waiting for hot water to reach distant fixtures from a centralized tank. The green benefits align with environmentally conscious lifestyles and consumer preferences trending toward sustainability.
7. Smart Connectivity
Many modern tankless water heaters offer advanced electronics, digital interfaces, Wi-Fi connectivity, and integration with smart home platforms. Some of the convenient features allow:
- Monitoring your hot water usage patterns
- Customizing delivery temperatures remotely
- Setting heating schedules and vacation modes
- Receiving maintenance alerts and notifications
All these are accessible via smartphone apps for on-the-go control. Touchscreen controls and digital display interfaces also make on-unit adjustments much easier compared to the analog dials and gauges on outdated tank models.
Smart water heaters can also participate in utility demand response programs.
These programs help balance electric loads by cycling tankless units briefly during peak events. Participation earns bill credits or incentives while barely affecting hot water availability.
From Conventional to Cutting-Edge: The Ultimate Conclusion on Tankless Water Heater Upgrades
Upgrading to a tankless water heater provides countless benefits spanning from reliable hot water delivery, energy savings, flexible installation, to quiet and safe operation.
Although it requires a higher initial investment, a properly sized and installed tankless heater will provide a rapid payback along with 20+ years of efficient and endless hot water. Going tankless takes your home’s comfort and efficiency to the next level.

By considering the pros and cons of tankless systems, homeowners can decide if such a system meets their needs.
This guide breaks down the key benefits and drawbacks.
Pros of a tankless water heater
1. Energy Efficiency
One of the main attractions of tankless water heaters is their exceptional energy efficiency. Because they only heat water on demand, they avoid the standby energy losses associated with storage tank heaters.
Studies show tankless models being 24-34% more energy efficient on average. This equates to significant energy savings over time.
2. Space-Saving Design
Tankless water heaters are far more compact than traditional tank heaters. They take up much smaller indoor and outdoor space compared to bulky tank units. Many models are designed for convenient wall-mount installations. For small living spaces, the design can be hugely beneficial.
3. Continuous Hot Water Supply
Homes with storage tank systems can often run out of hot water during high demand. Since tankless heaters provide on-demand hot water, they eliminate problems with depleted hot water availability. The unlimited supply is ideal for larger homes with extensive needs.
4. Longer Lifespan
While storage tank heaters typically last between 8-12 years, tankless units have lifespans of 20 years or longer. Their average working life is nearly double that of tank heaters.
With proper maintenance, some models function effectively for up to 30 years before needing replacement. The enhanced durability leads to higher long-term value.
5. Reduced Risk of Water Damage
Because tankless heaters don’t store any water internally, they carry no risk of internal corrosion and leakage.
On the contrary, for tank storage heaters, tank corrosion is common over time, often resulting in cracks and water damage. Tankless models provide greater installation flexibility and prevent costly repairs by removing this leakage risk.
6. Customizable Temperature Settings
Tankless water heaters give users precise control over output water temperature. Temperature can be easily adjusted via digital controls or smartphone apps.

7. Lower Operating Costs
Tankless water heaters’ exceptional energy efficiency and durability translate into lower monthly costs for homeowners.
Reduced energy consumption cuts electricity bills substantially compared to conventional models. And with a working life span of up to 30 years, replacement costs are minimized as well and long-term savings add up tremendously.
Cons of a tankless water heater
1. Higher Initial Cost
While tankless heaters save money in the long term, their initial purchase price is significantly higher than that of traditional water heaters.
Unit prices range from $600 up to $3,500 depending on size, flow rate, and features. Installation also tends to be more labor-intensive and complex, resulting in higher total costs. The steep upfront investment deters many homeowners.
2. Limited Flow Rate
A common downside of tankless systems is constrained flow rate, particularly with basic whole-home models. While storage tanks easily support simultaneous use across multiple fixtures, tankless heaters have limited heating capacity.
Basic units may provide only 3-5 gallons per minute (GPM) – enough for just a couple taps at once. Upgraded models are needed to power whole-home demand.
3. Cold Water Sandwich Effect
Occasionally tankless heaters exhibit a phenomenon known as the sandwich effect. This refers to a blast of cold water between cycles of hot water delivery. It’s caused by small amounts of cooler water left in internal pipes being pushed out by newly heated water.
4. Not Ideal for All Climates
Homes in extremely cold climates are often poor candidates for tankless installation. Heaters must fire at full capacity to raise near-freezing inlet water to suitable temperatures. As a result, output flow rates suffer drastically in cold weather.
Additionally, tankless heaters are vulnerable to freezing without sufficient indoor buffering from frigid outdoor air.
5. Maintenance Requirements
While tankless heaters last longer, they require more routine maintenance over their lifespan. Annual inspections and water flushing are recommended to maintain efficiency and prevent operational problems.
They will occasionally require professional servicing at added costs. If ignored, mineral buildup can accelerate wear on internal components as well.
6. Complex Installation
Switching to a tankless system often necessitates extensive modifications to existing plumbing and gas lines.
New dedicated electrical circuits may be required as well. And without a sufficient flow rate to start, units won’t ignite. All these factors complicate DIY installations. Tankless setups usually call for professional expertise – tacking on thousands more in labor expenses.
Flowing Forward: A Final Verdict on Tankless Water Heaters Advantages and Disadvantages
Tankless water heaters offer benefits like endless hot water supply, potential energy savings, compact size, and enhanced durability. These advantages of tankless water heaters may justify the steep initial investment required and occasional quirks.
But tankless models also have distinct drawbacks ranging from high costs to climate suitability issues, so there is no universal “best” option.
By weighing the pros and cons, each household can determine if transitioning from a storage tank heater to an on-demand tankless unit meets their requirements and needs. With sound information, homeowners can choose the hot water solution that fits their lifestyle and budget.

HEAT PUMP HOT WATER SUPPLY & INSTALLATION
Energy Saver is an initiative proudly funded by the NSW Government Harnessing the Power of Heat: An Overview
An electric hot water setup uses power to heat an element. This warm element heats the water in the tank. It’s a straightforward process but might involve major costs.
Solar hot water setups use sunlight to warm water and they require solar panels. These panels take in the sun’s energy and transfer it to a storage tank. This green method might lower your bills over time, but for it to be operational, it needs direct sunlight.
On the other hand, there’s the innovative heat pump hot water system, which is gaining popularity due to its energy efficiency. Instead of directly generating heat, heat pump systems extract heat from the surrounding air and transfer it to the water.
This makes them highly efficient and cost-effective.
Electrifying Warmth: The Mechanism Behind Electric Hot Water Systems
Many families choose electric hot water systems over other types. This is because they are reliable, simple and easy to understand. Electricity is used to heat an element. The element, in turn, warms water in a tank. This ensures that you always have hot water.
Here’s how it works. You turn on the hot water tap. Cold water from your main supply replaces the hot water you’re using. It enters the tank in your hot water system.
The heating element inside, which might be made of metals such as copper or stainless stell, gets warm.. As electricity runs through this element, it heats up.
This heat then transfers to the water and the entire process warms up the cold water to reach the required temperature. It’s a neat system!
Electric hot water systems maintain a steady temperature. They have a thermostat that detects when the water gets cold. When the temperature goes below the set point, the thermostat sends a signal to the heater to switch on, and the cycle starts again.
One plus side of these systems is they can provide hot water whenever needed. Solar or heat pump machines need sunlight or certain air temperatures to work well. But, electric machines can create hot water regardless of outside conditions.
However, always remember that these machines can have high running costs due to fluctuating electricity prices.
The Sunshine Heater: Understanding Solar Hot Water Systems
You can use solar hot water systems to heat up the water at home. They use the sun’s power and include panels that capture this energy. They then move it to a storage tank where the water gets heated and prepared for usage.
What happens when sunlight hits these panels? Well, it changes into heat. This heat transfers to a fluid, either water or a water-glycol mix. This fluid circulates through the panels, soaking up the heat and then gets pumped into the storage tank.
Inside the storage tank, this heated fluid warms up the water, raising its temperature to your desired level. The heated water is ready for use with just a turn of the faucet.
Hot water systems aren’t just green; they can save you considerably on power bills as well. When you harness the sun’s energy, your need for electricity or gas to heat water decreases tremendously. But remember, solar hot water systems need sunlight to work and as a result, how well they work might change depending on where you live and the time of year.
The Science of Comfort: How Heat Pump Hot Water Systems Work
Heat pump hot water systems are a clever and effective method for household hot water supply. These systems aren’t like electric or solar systems since they don’t directly produce heat. What they do is use heat from the surrounding air to heat the water. Let’s delve further into how this brilliant tech works.
The process begins when heat is pulled in from the air. Heat pumps use a special substance called a refrigerant which extracts the heat from the air and evaporates, forming a gas. By squeezing this gas, it gets even hotter.
Next, the heated refrigerant gas shares its heat with the water in the storage tank. A coil system inside the tank allows for this heat sharing to take place. The hot gas cools down and changes back to a liquid.
While transferring its heat to the water, the refrigerant goes into an expansion valve. Here, it turns back into a low-pressure gas and the cycle starts all over in the evaporator.
Heat pump hot water systems have major perks. With a low consumption of energy they are able to produce a high output, up to three times more than electrical systems! They’re both good for the environment and your wallet.
How long does it take for a heat pump hot water system to heat water?
The time it takes for a heat pump hot water system to heat water depends on various factors, including the desired temperature, the size of the tank, and the ambient temperature. Generally, it will require a few hours to heat up an entire tank, depending on these variables.
Do heat pump hot water systems require regular maintenance?
Like any other hot water system, heat pump hot water systems benefit from regular maintenance to ensure optimal performance and longevity. This typically involves cleaning or replacing filters, checking refrigerant levels, inspecting electrical components, and verifying the overall system operation.
Are heat pump hot water systems more expensive to install compared to other types?
While the initial installation cost of a heat pump hot water system may be slightly higher than that of traditional electric or solar systems, the long-term savings in terms of energy costs can often outweigh the upfront expense.
How Do Hot Water Systems Work – Final Thoughts
In this article, we’ve highlighted the importance of hot water systems in our everyday lives. From electric and solar to heat pump systems, each system utilizes heat to give us the needed warm water. Every system has a number of benefits that are important to keep in mind.
Therefore, whether an electric, solar, or heat pump system, leveraging the strength of heat assures a comfy supply of warm water for future needs.

HEAT PUMP HOT WATER SUPPLY & INSTALLATION
Energy Saver is an initiative proudly funded by the NSW Government What is a heat pump hot water system?
A heat pump hot water system is an energy-efficient way to heat water for domestic use. It works by extracting heat from the surrounding air and transferring it to the water stored in the tank.
A heat pump system’s key components are an outdoor unit containing the compressor, evaporator, and condenser coils and an insulated storage tank holding the heated water.
Unlike traditional electric or gas hot water systems that generate heat by burning fossil fuels, heat pumps use electricity to power a refrigeration system that absorbs ambient heat.
This makes them much more energy efficient, with some units having over 300% efficiency.
How do heat pump hot water systems work?
Heat pump water heaters use the same technology as refrigerators and air conditioners. The system has a compressor and refrigerant gas that circulates in a closed loop, absorbing heat from one place and moving it to another.
Here are the main steps of the process
- Air passes over the evaporator coil located in the outdoor unit. The liquid refrigerant inside absorbs the ambient heat, causing it to evaporate into a gas.
- The compressor compresses the gaseous refrigerant, increasing its temperature.
- The hot refrigerant passes through a condenser coil that is in contact with water stored in the tank.
- Heat from the refrigerant is transferred to the water, rapidly heating it up.
- The refrigerant cools and condenses back into liquid, starting the cycle again.
This heat extraction and transfer process happens continuously to keep the stored water heated to the desired temperature.
Benefits of heat pump hot water systems
Heat pump hot water systems offer several benefits compared to conventional electric, gas, or solar water heaters:
1) Energy efficiency
Heat pumps can reduce water heating costs by up to 75% compared to electric storage systems. This is because they use free ambient heat rather than generating heat by burning fossil fuels.
2) Cost savings
The high energy efficiency translates into significant cost savings on electricity bills in the long run. Heat pumps have a higher upfront cost, but the long-term savings generally provide a good return on investment.
3) Environmental impact
Heat pump systems are a more sustainable and eco-friendly option, as they use renewable thermal energy from the air instead of finite natural resources. They reduce carbon emissions compared to conventional water heating methods.
4) Efficient performance in any climate
Heat pumps can operate efficiently year-round, even in colder climates. Models with enhanced features allow them to extract heat even when air temperatures are as low as -15°C.
Factors to consider when choosing a heat pump hot water system
There are several important factors to keep in mind when selecting a heat pump hot water system:
1) Capacity
