we havent had any issues so far with both units, and I'm sure we will not have any problems in the future. We are very pleased with the product and the way it functions and it actually does the job better than we thought it would. it heats up very quickly

We have had no trouble with the Hydrotherm at all. In fact we have purchased two in the last couple of years for different houses. Any questions before purchase were immediately answered by the manager/owner. The hydrotherm runs efficiently in the background without us having to do anything. The settings are easy to use, and the readings show exactly how hot the water is. It also looks great. Slight noise like A/C unit which was expected. No issues at all. Thanks team.

So far so good! After my last system packed it in I approached Hydrotherm for a Heat Pump alternative. Their price point was much better than anyone else, and the installation was quick and stress free. As I'm in real estate, service means everything to me and I cannot speak highly enough of the team...

I purchased a Hydrotherm water heater and find it efficient, economical on both water and electricity, even heating, easy to install and a great looking unit. It was recommended by the company that put in our solar system and works beautifully in conjunction with it as so far no electricity charges for the heater.

This is the third Hydrotherm we've purchased. We recommend them to all our clients. Easy to change the timer settings. We never run out of hot water and our power bills aren't too bad. Dealing with Dewet is an absolute pleasure. He is very efficient. Communication is excellent. Very happy customer.

Easily copes with 2 long showers and 2 loads of washing in 1 day. We live in a cold climate (Canberra) and have had it for 6 months with a very cold winter. No problems at all. By using the inbuilt timer I've set it to heat from 1 pm to 5 pm as needed. This is when the air temperature is highest and the sun brightest, so by using the power from my solar panels it costs me nothing for hot water. Have now disconnected from gas saving me around $300 per year in connection costs alone. Win, win. Very happy.

have owned a Hydrotherm Heat pump since late 2012 and have to say that the after sales service is the best I have experienced with any product. I have had on 2 occasions needed to call about alarm going off on the heater and they have talked me through how to reset the pump on 1st occasion and arranged for someone to come out within 3 hrs on the second occasion to look at the sensor. Only other time I needed a call out there was no charge. Kudos to Simon and rest of the staff they are very professional and provide great service

I have had to contact the installer 4 times in the last 2 years. System stops producing hot water. Panel starts to light up with all sorts of messages. Installed in July 2014. We have had to have cold showers many times. Not happy at all with the product. Very frustrating to come home and have a cold shower.

Have been very happy with the product after 7 months and have seen significant savings on electricity compared to the previous electric hot water system. Customer support has been fantastic and always answered any questions I had. Would highly recommend this product to anyone considering a new hot water system.

Have owned Quantum and hydrotherm. Had 10 reliable no fuss years service out of our Quantum HWS before we built and moved to a new place. The builder had put in a Hydrotherm and told us how “great” they were. Well in 2 years we have had 3 installed and another one has packed it in. They are cheap imported junk, don’t waste your money, time and sanity. You have to fight tooth and nail for a warranty claim with threats of fair trading to get any joy and hope you win the Hydrotherm lotto and jag a good unit. If you buy one I wish you good luck!

Our water heater works to expectation with better flow than with an earlier model. There was an initial problem caused by a blockage in a filter - but that was sorted by the designated plumber - at our expense I seem to remember. The filter had trapped a small piece of plastic - could have originated during manufacture or when the product was unwrapped.

Have used it for over six months now and meets all expectations.
Very good quality product, well made and of robust design and workmanship.
Noise from compressor is no more noticeable than an air conditioner and does not run for too long to be intrusive.
I would highly recommend this product.

A good unit, however could do with greater capacity, perhaps the temperature could be set higher so that less hot water is required in the mix when showering.

We are a family of three adults and if all three shower around the same time hot water runs out.

I will look at raising the temperature, however 20% more capacity would make this unit ideal for us, I don’t see how this unit could suit a large family.

When it comes to hot water systems, it's not often you would write about the look and design but in the case of Hydrotherm, that is the first thing that comes to mind. It looks apart and works a treat. The best feature is the ability to set timers which allows me to match the running time the unit to the best solar production of the day to offset the electricity cost.

Its actually a very stylish slim system. Never heard or seen of this particular product HydroTherm until it was recommended by my plumber.It has suited us as a family of 3 Adults with long showers. Certainly coming under the running cost of my last system, much quieter and over the moon with the purchase price. This is the only system i would ever recommend. And I have :)

Hydrotherm have the best heat pump on the market!! I am a service tech, and I have been worked on a many brands in the market and have found HydroTherm to be the best most reliable and easy to service system. Give a heat pump a go you will save on your energy bill!!

I have only had the heatpump a few weeks, but so far Im pretty impressed.
I have it connected to my solar supply, and have set it to a manual timer so that it turns on to heat the water when my solar is up to its higher production period from 9am till water is heated. It is supplying hot water for 4 adults. We often have family stay in a granny flat (another 2 young adults, which means long showers) and so I set the second timer to turn on for a couple of hours early in the morning to give the water a topup boost. I was pleasantly surprised by its noise level as its not too loud (noisier than air con compressor but less than pool pump) and as it is on mostly in day hours, it doesnt affect us or the neighbours.

Hot water system works well and keeps a good amount of water hot and functions as expected. System is a nice looking unit and good in general appearance. Is louder than expected when heating and external fan seems noisy than I was expecting. Definately wouldn't want it anywhere near a sleeping area.
