Compare Best Electric Hot Water System Tanks
The best electric hot water system (best electric hot water heater) tanks or cylinders have been the most common hot water system in Australia for decades.
Unfortunately, with the rising cost of electricity and the high greenhouse gas emissions associated with generating the required electricity, these units are falling out of favour.
In fact, the government has passed legislation to try and limit their use.
Electric water heaters that heat all day are your most expensive option.
Off peak electric storage units are better, as off peak electricity tariffs are lower.
However, as they only heat water at night, they need to be quite large to make sure you don’t run out of water during the day.
The bigger tank would also cost more to purchase.
Still, many people with an old electric unit are tempted to replace like-for-like and continue using an electric storage unit.
It is a quick, one day fix and the upfront costs are not prohibitive. However, the long term disadvantages need to be considered.
Compare Best Hot Water System Review – Best Tank Hot Water Heaters
A gas hot water systems review would involve a comparison between the best tank hot water heaters and the the best gas instantaneous hot water system.
The installed cost of a gas hot water tank is close to that of the electric hot water systems, especially if you already have gas at your home.
Gas hot water tankare energy efficient, particularly if you choose one of the new 4 or 5-Star models, and they have much lower greenhouse gas emissions. Compare that with the best gas instantaneous hot water system now available in 7 Star units.
This means that gas hot water tank do not need to be as large, as the gas burner can operate whenever required.
Installation is normally accomplished within one day.
Gas Boosted Solar Hot Water
Gas boosted solar hot water can have some of the lowest running costs and greenhouse gas emissions, but they are typically the most expensive to install, with installed cost as much as 4X that of a storage unit, even with rebates. Gas boosted solar hot water are equipped with a booster unit for periods without sufficient sunlight.
Solar hot water system boosters can be electric, natural gas or LPG gas boosted solar hot water system
It is important that you提高了太阳能热水购买天然气with a sufficient number of panels and tank storage, so that the booster is not overused, or the running costs will be higher.
Your roof configuration also needs to be compatible with gas boosted solar hot water.
The gas boosted solar hot water option may take a number of days to install.
Compare Heat Pump Hot Water
Heat pump hot water heats your water by extracting heat from the ambient outside air, in the same way that a reverse cycle air conditioner would heat a room. Some say heat pump hot water are the best electric hot water system.
Heat pump hot water can be quite efficient and have low greenhouse gas emissions but, once again, the upfront costs are substantial.
Heat pump hot water also have a couple of weaknesses that have caused them to lose popularity in the last few years.
Because they essentially incorporate an air conditioning unit, there are many more moving parts and the maintenance costs tend to be higher than for any of the alternatives.
They also have the dubious distinction of requiring as many as 3 trades for repairs: an air conditioning mechanic, a plumber and an electrician.
The other issue is noise.
It can easily need to run all night because of the colder ambient temperatures after dark.
Heat pump hot water can be very noisy.
Best Gas Instantaneous Hot Water System – Best Gas Instant Hot Water System
最好的气体瞬时热水系统also be the best continuous hot water system . A gas instant hot water system is also arguably the best gas hot water heater and the best hot water system.

How a Tankless Water Heater Works
• Cold water flows into the water heater when a hot water tap is opened inside your home.
• The water flow is detected by a sensor that ignites the gas burner, to heat the water in the heat exchanger.
• The water typically follows a serpentine pattern through the heat exchanger, absorbing as much heat as possible.
• An electronic control unit modulates the gas burner to maintain a set water temperature.
See all the details on:
Combustion Efficiency & Star Ratings
Star ratings encapsulate both a start-up heat up factor for each appliance and combustion efficiency.
As a result, combustion efficiency for each star rating can vary a bit.
However, if we look at combustion efficiency in isolation, it does make it a bit easier to understand what it all means.
The following are all approximate but will give you a good idea what to expect based on what star rating you choose:
4 Star = 73%
5 Star = 80%
6 Star = 87%
7 Star = 94%
Size and Aesthetics
At about the size of a small suitcase, tankless gas continuous flow instantaneous hot water systems are the best looking, as they are much smaller than a traditional storage tank heater. Mounted flush against the wall, the smaller tankless gas continuous flow instantaneous hot water systems are better, as they take up less space and are also more aesthetically pleasing, as they don’t dominate the exterior appearance of your home.
Storage tank hot water heaters are big, especially the electric off-peak models.
Even when installed outdoors, the size can get in the way, particularly with today’s smaller lot sizes.
Health & Safety
The World Health Organisation — WHO — recommends that stored hot water be kept at a minimum of 60°C.
Unless a minimum of 60°C is maintained, hot water tanks can be abreeding ground for Legionnaires’ disease或者是由细菌，军团菌肺炎引起的军团菌。
It is a respiratory disease that can cause severe pneumonia and is sometimes fatal.
However,Canadian studieshave shown, even when the thermostat is set at 60°C, a high percentage — approximately 40% — of electric water heaters remain contaminated.
A tankless gas continuous flow instantaneous hot water systems is best at the prevention of bacterial growth, as there is no stored water in which bacteria can breed.
Tankless gas continuous flow instantaneous hot water systems can also be better set at 50ºC, so the risk of scalding is greatly reduced without the need of atempering valve.
What Size Hot Water System Do I Need?
Don’t Calculate by Number of People or Bathrooms
Some suggest that you calculate by the number of bathrooms in your home while others say to go by the number of people in your family.
Also, in many cases, their recommendations are based on the worst case scenarios, assuming higher consumption than your actual water use.
Buying Too Large Wastes Money
The result is that many people end up buying a larger system than they actually need.
Simultaneous use is one of the fundamental determining factors.
The number of people in your home combined with how and when they use hot water is the key.
- Do they all take showers at the same general time of day?
- Do they take showers simultaneously in different bathrooms?
- Do the showers have威尔斯3星级的淋浴头(maximum 9L/Min) or standard 18 to 25L/Min showerheads?
- Do some prefer baths, which use more hot water? Is the bath or spa oversized, requiring even more hot water?
- Do you run the washing machine, using hot or warm water, while people are showering?
- Is your dishwasher connected to the cold or hot water? If hot, do you use it while hot water is being used elsewhere?
Showers Are the Key – Water Saving Shower Head
最热水淋浴使用一个家。人克enerally shower for 5 to 10 minutes. Assuming you have a 3 Star water saving shower head and you mix in some cold water with the hot, the typical hot water consumption would probably be in the 7 litres per minute range.
If you also assume an 8 minute shower, water saving shower head will consume about 56 litres of hot water per shower or a family of four would consume 224 litres.
The use of WELS (Water Efficiency Labelling and Standards) 3 star rated water saving shower head is an important factor in saving water and energy whilst reducing the size and cost of the hot water system required.
Hot Water Tank Example
In the above example with water saving shower head, if all four people take their showers in the morning, you would only need astorage hot water system由于224升第一小时容量，无论在同一时间淋浴多少。
This all presumes that you are not using any other hot water devices at the time.
The use of additional hot water, after the shower period, would depend on the hot water system’s recovery time required to achieve full temperature.
So, with a larger family or house guests, a bit of scheduling may be required to avoid the need for a larger unit.
Off Peak Electric Issues
Off peak electric storage units are a completely different story.
Inasmuch as they only heat water at night, they need to be quite large to make sure you don’t run out of water during the day.
The bigger tank would also cost more to purchase.
Tankless Hot Water Example
为一个tankless continuous flowunit, it would depend on how many showers are being used simultaneously.
Using the example above, if it’s two showers, then you only need a unit with a minimum flow rate of 14L/min.
If you have 3 people showering at exactly the same time, you would need a minimum 21L/min.
这假设您不使用其他热water devices simultaneously.
Tankless gas continuous flow instantaneous hot water systems are the best, as recovery time is not an issue with continuous flow units, so even a large family with guests would not run out of hot water.
