Installed now for about 6 months, 2 + visitors household, no hot water supply issues at all even with 4 in household at times. Power consumption about half compared to the old storage electric unit, now getting a rebate on solar power compared to about $200 quarterly bills. Not very noisy, can just hear fan outside en-suite with window open. A bit tricky to program, but once set, trouble free. Holiday feature works a treat.
Would recommend this as a quality unit performing to spec...

Got this as a cheap alternative to a battery. Run it mainly during solar hours, but early on I realised our night showers mean we need it to be allowed to run until about 11pm if necessary. This it's fine, but we don't run it later since it does produce a bit of noise, but not too much and have not tried the low noise function. Speaking of the functions, they are ok but the computer is really unintuitive. I mean really bad. I had to watch the video about 4 times to reproduce the steps an I'm an electrical engineer. In this day and age, surely it's cheaper to fit it with wifi and a web server than to install an LCD screen with obscure symbols on it!
Super cheap to run. If you have solar, definitely get a heat pump hot water cylinder.

Bosch Compress 3000. Failed after only 3 years. Thats why you only get a 2 year warranty because it is expected to fail. A con if ever there was one. So much for German 'quality'.

Failed after just 2 years will go back to standard heater, very dissapointed,so much for German quality,wont miss the racket it made either do not waste your money on one of these.

We discovered the Bosch Compress heat pump is no longer being brought into Australia when we had some issues recently.

Typical when the going gets tough the product line is dropped.

Had one of these fitted to our brand new house it has continually come up with fault EO-9 ( which means purge system) after four weeks got in touch with Bosch I was told system needs purging after plumber came and purged it it failed again two days later rang Bosch they sent there plumber around and was told these facts
They have problems if you have hard water issues the plumber has told me it will cost me $2500 to install water a softening filters for this appliance to run correctly
My advice is to do your homework first on what your waters like before you purchase this model

We chose this unit to put into our new house when it was completed 3 months ago. We have been very impressed with the unit and the savings to run it. We have it set up to run in the morning early when the solar panels are generating power. The noise is not really an issue. It is outside the laundry and it only runs for a short time anyway to heat the water. We have 3 bathrooms and have plenty of water to use more than one bathroom at a time. It only took my partner a short time to work out the programming of the unit and the plumbers seemed to be able to install it without any major issues.

Three weeks after connection and still not running right!! Bosch service team have tried to fix it and it fails every time after they leave. There hasn't been continuous hot water since it was connected. Bosch sales person will not replace it with a new one!!! Save yourself the stress, and avoid!!!

We bought a Bosch Compress 3000 DW and find it so noisy, we need to shut all the windows otherwise it wakes us up, thank goodness our neighbours are not in their house very often otherwise we would get a major complaint from them. Does anyone else have a very loud unit, is this usual for them, if so we will need to end up replacing it at a major cost because it is unbearable.

The Bosch Hot Water Heat Pump we purchased from Specialized Heating and Cooling is very good and the savings off our home energy bills are amazing, if I was you I would replace your electric or gas units with a Bosch Heat Pump it’s ideal and works great all year around with the unit working down to -7 deg and a dB of 41db or program it to turn off and night and back on in the morning so 0 dB over night.

I bought my Bosch Hot Water Heat Pump form Swan Plumbing and I’m very happy with the savings now off me energy bills.
Bosch Hot Water Heat Pump is amazing and the guys that installed it did a great job connecting it also to my PV system which if me even more savings.

Had the system for a few months in a very cold location in hills east of Melbourne. Works well. Easy to install, big savings on power bills (about $3 a day) and no dramas with hot water running out. You can set the temperature of water easily so can have it as hot as you want (to within safety limits). Programming is easy, but to be honest unless you know what you are doing systems best to be left on standard settings imho.

The system is designed for a 3-4 person household. If you want more hot water you need a bigger system... and will need to pay for it.

This hot water unit is a complete dud. We are a family of 5 and we can't even get 4 showers before we run out of hot water. We have new house and in the process of ripping it out and replacing it. Very disappointed as this is the biggest unit Bosch makes

I agree the unit with solar panels is great. However the programming manual is not well written and unit interface not intuitive to setup, Has anyone written a simple set of instructions?
( and for some strange reason i need to write at least Fifty words. I have now do that.

The plumber installed the system and it ran fine for 3 days, now it has stuck on Auto and only heats the water to 37o. I rang for help on the 1300 number on how to re set it and couldnt get any satisfaction. We are in the country and not close to a plumber.

Very happy with this system. We used the built in settings to only operate between 10 am and 3 pm and had our electrician wire us onto general supply. As we have solar this means we are not feeding back to the grid at 7c but heating hot water first. Family has 6 showers a day and we have not run out of hot water even a bath now and then on a Sunday afternoon. 43 units of power used in one calendar month (QLD summer) the heat pump transfer really makes use of that power. Once a week the system high heats on a legionaries setting, just have to remember on that night we need to add more cold water as what comes out is quite a bit hotter.
