quality of the product and professionalism of the installation was wonderful. The Haier heat pump was installed a month ago and has been working extremely well so far with only a small amount of energy is being used from the battery. Time will tell but I believe a lot of energy saving and cost saving is only a good thing in a long run for our family.

most of the year when its above 30deg it works ok. Not that you really need much hot water during those 6 months of the year. Around mid may every single year. Every morning I hear "There is no hot water again". Every night "There is no hot water again" From my wife and two young kids.
For all the emails and phone calls I have made to try and rectify the problem. The only attempt to do so was to send a plumber out to reset some thermostatic something or rather in the software which did nothing at all.
The only way I have to ensure there is any hot water, is to go out twice a day and make sure it is forced into the on position in either hybrid or hybrid 1 mode.
The 15 year old Saxon this unit replaced probably didnt even get looked at twice in 15 years. Yet here I am baby sitting this POS appliance twice every single day to ensure the missus and kids can have a hot shower when they want one.
All these pics are after the system has run all day long consuming between 6-10kw/h. Considering the old system used around 9kwh per day and we were told this new system would be around 2.5kwh.....
The company that did the installation did a stellar job I might add, Could not fault their workmanship and they tried to assist as much as they could when we started having issues. But Im not going to continue wasting their time trying to rectify an issue with the product itself. The only real option we have going forward is to move to an IStore or go back to a traditional HWS.

now proven to be correct. We purchased the Emerald system through Carbonsavers Melbourne because of the good reviews we saw on both Carbon Savers and Emerald on Product Review and other sites highlighting the high quality of the product, the backup service and the standard of the installation. This too proved to be correct, starting with Ella from Carbon Savers who oversaw the purchase and planning and Martin also of Carbon Savers who ensured that the installation complied with all specifications. This was followed by the installation team of Brady and Ryan who were punctual, knowledgeable, efficient and obviously took pride in their work. Seventy minutes after their arrival the only obvious sign of their visit was a new 320 heap pump heating our water. Thank you team

timer to not heat during peak 3-9pm period.The compressor above the tank is very quiet. I added a white drain pipe from Amazon to drain excess water from the compressor away from the tank and onto the ground. Maybe I should have bought the wi fi option as I need to reset the clock on the timer for each DST changeover but this is hardly an inconvenience. Actually changing the time also reminds me to purge the tank as well.

refilled the tank with peak electricity and somehow still managed to deliver only cold water for a $6k energy bill. CATASTROPHIC SCAMMERS SHOULD BE SHUT DOWN. I have a worthless heap of junk on my roof - maybe the problem could've been easily rectified - I can't afford another bill to find out. Endless phone calls and messages - I tried countless times for months, years. This was an expensive system. I would've had more hot water from a kettle. Even my skilled electrician couldn't get the junk to work. Tried a booster button and it still just dumped any warm water it heated with the peak electricity. It doesn't take much to answer a phone or a message on a website - THAT TELLS YOU EVERYTHING - THEY REALLY, TRULY DON'T GIVE A DAMM ONCE THEY HAVE YOUR MONEY.

I try to get some solution from envirosun the customer service man hung up on me as he said " I wasn't listening to him" It was very disrespectful how he spoke to me. This leaves me with no way to find if this much water loss is normal and how I am meant to redirect the water as the plumber didn't even mention this little fact. These systems are very noisy too if folk like peace. I would not recommend this product and definitely not this company.

support, I was told the warranty was void because I hadn’t completed a 5-year service—something that was never disclosed or explained at the time of sale.
NeoPower refused to take any responsibility and offered no resolution. For a product marketed as long-lasting and reliable, this is extremely disappointing. Their warranty policy is vague and unfair, and customer service was dismissive and unhelpful.
I also visited the NeoPower website and found that all links and references to the warranty terms and conditions are not publicly accessible.
Would not recommend—look elsewhere if you want durability and support you can rely on.

Types of hot water systems
Heating water for use in the bathroom, kitchen, and laundry uses over a quarter of the average household’s energy, which is why it’s important to carefully consider what kind of hot water system is right for you.
You’ll have to first decide what kind of heating method you want to use for your hot water system: gas, electric, solar, or heat pump.
Gas hot water systems · See all
Gas is quite an efficient energy source, so it can be a good option if you have a natural gas connection. Natural gas is significantly cheaper than LPG.
These systems are usually installed outdoors because they need adequate ventilation, but they can be installed indoors with a flue.
Electric hot water systems · See all
Electric water heating is relatively cheap to buy and install, but ongoing costs can be expensive. However, if your meter includes off-peak rates, then this should be cheaper.
Solar hot water systems · See all
A solar hot water system needs to be installed in a sunny spot for it to be efficient. This means that they do tend to work better in certain parts of Australia, particularly Queensland and the Northern Territory. You might even want to buy a larger tank for days with less sun or when you want to use more hot water.
Most of these systems will still have either a gas or electric booster to ensure that hot water is always available, regardless of the climate.
Heat pump hot water systems
Heat pump systems use electricity to transfer heat from one place to another rather than directly generating heat. These units need to be installed in a place with good ventilation, generally outdoors. Heat pump models can save you up to 80% on the cost of hot water compared to an electric storage system.
Storage vs instantaneous hot water systems
A hot water system can be either an instant system or a storage tank system.
Instant systems
Also called continuous hot water systems, these only heat water when they're needed. They aren’t actually instant, but they usually just take a few seconds before you get hot water. Most models use gas, but you can still find electric models, which are typically only designed to heat water for a single water outlet.
A continuous flow system can be more suited to smaller households, as they’re cheaper to run and more practical than having a storage tank.
f you’re considering an instant hot water system, then you should consider its flow rate. You should opt for a higher flow rate if you have many water outlets in your home. A general rule of thumb is to get a flow rate of around 22 to 24L per minute for a house with two bathrooms.
Storage tank systems
These store a certain amount of heated water that can then be used throughout the day. Most gas, electric, solar, and heat pump systems use a tank.
They’re generally more cost-effective and so can be suited to households that use a lot of hot water; you just need to ensure you get a large enough tank to ensure the last in line for a shower isn’t left in the lurch mid-rinse.
If you have off-peak electricity available to your home, then these systems can take advantage of these cheaper tariffs.
These tanks are insulated, but it’s still a good idea to install them in an insulated or sunny place to minimise heat loss.
What to consider when choosing a hot water system
There are a few other things you should consider when shopping around.
Your household size and energy use
Understanding the hot water needs of your household is key to getting the right hot water system. An undersized system means that someone will probably miss out on a hot shower, while a system that’s too large will mean you’re paying for something that you’re not fully using.
The average Australian uses around 40 to 50L of hot water per day - more if you take long hot showers or often use hot water to wash clothes.
Here’s a rough size guide for water heaters, but you should also consult the manufacturer of a hot water system you’re considering buying as well as seek advice from an installer.
For storage tank systems, consider the number of people in your household:
- A 1-2 person household could be fine with a small storage tank of around 90L.
- A 4-person household will need around 135-170L.
- Households of 5 people or more may find it more economical to find a large tank of between 200-300L than install multiple continuous systems.
For continuous hot water systems, consider the number of hot water outlets in your home and peak usage:
- A 2-bathroom household will need 22-24L/min flow rate.
- If you expect 2 people to be showering at the same time, you need at least a flow rate of 14L/min.
- There’s also the option to install multiple systems and have them in different parts of your home.
Energy efficiency
The most efficient type of hot water systems are heat pump and solar water heating systems.
If you’re shopping for an electric storage system, a gas storage system, or an instant gas hot water system, look for Minimum Energy Performance Standards (MEPS). You may see energy efficiency ratings on gas systems, but these aren’t government regulated.
Price
Excluding installation, prepare to pay the following upfront:
- Gas hot water systems often cost between $900 and $2000.
- Electric hot water systems usually cost somewhere between $500 and $2000.
- Solar hot water system prices can vary a lot, but usually cost between $4000 and $8000.
- Heat pump models range from $2000 to $4000.
Hot water system installation costs vary a lot depending on the job and system you opt for. If you’re switching out your current hot water system with one of the same capacity and in the same location, installation typically ranges from $300 to $700. If you’re moving the system to another location, then you may have to pay between $1100 and $2500 depending on what kind of plumbing and electrical work is required.
You should also check for warranties. While these vary, most hot water systems should come with a warranty of at least 7 years - the longer the warranty, the more the manufacturer backs the quality.
Look for government rebates and incentives
There are a range of incentives offered by the federal and state governments - such as the federal government’s Small-scale Renewable Energy Scheme - for households to switch to energy-efficient hot water systems, particularly solar and heat pump systems.
A hot water system installer may also be able to tell you about rebates that are available to those living in your area.
