Bosch Compress 3000
Verified42 reviews
Try something else like solar – Our Compress has died after 4 years and 9 months in our new home. The service agent diagnosed the problem to be the compressor which Bosch produced themselves and is no longer available. Apparently Bosch took this product off the market after huge losses. I was tempted to change back to a standard electric HWS but decided quickly to go with an… Read more
IStore heat pump with full 5 year warranty including labor. I regret not going with an electric boosted solar HWS which we had on our previous two houses and had no issues for over 10 years. Very disappointed with Bosch.
Clock problem – We have had a compress 3000 fitted for about 4 years & have been happy with it, then a few months ago it started dropping the time of day & when reset will often stay at the time you set it to & not keep time. Really annoying, as now we have to set it to manual & turn the power on & off. Show details
4 years old and it's now got an E04 error – This has been doing faithful service so far, but I am now concerned seeing the reviews from others. Installed Jan 2019, so 4 years old. The 1-year manufacturer warranty is pitiful, so I'm watching carefully how Bosch responds to this. This was a $3,178 purchase at the time, after $870 in STCs ($4,048 full price). A failure after 4 years does… Read more
not pass the test of "reasonable durability", especially at that price. A reasonable lifespan for a hot water service is easily 10+ years.
From the ACCC: After the warranty expires, the consumer guarantee of acceptable quality usually still applies. This means that if there’s a problem with a product, the consumer likely still has a right to a repair, refund or replacement, even after the warranty period.
Businesses must not mislead consumers into thinking that their rights are limited to the remedies or timeframe set out in a warranty against defects.
When a business sells a product with a major problem, or a product that later develops a major problem, it must give the consumer the choice of a refund or a replacement of the same type of product.

Great idea, shame about the service – Initially I was very pleased with this unit but then I had to call the plumber out 3 times in the 2-year warranty period as it would fault out due to a combination of running the Legionnaire Cycle and very hot days, typically 40C, which are not exactly unusual in WA. When the same fault occurred just out of warranty I was annoyed that Bosch… Read more
refused to refund the cost of the plumber as this was a pre-existing fault. After months of correspondence, and ongoing faults, Bosch sent their plumber around to modify the unit (two wider bore pipes to increase flow?) they also reprogrammed to a higher temp, and set the Legionnaire Cycle to run at night, which is unsatisfactory as I bought it to work with my solar installation. In my opinion this modification means Bosch acknowledge their unit is faulty, or unsuitable for local conditions. Bosch seem to now consider the matter closed and their service department, both here and at HQ in Europe, no longer respond to my correspondence. The ongoing problems they are not dealing with is that they owe me the money I paid for a plumber's visit to service their faulty unit; that the unit scales up very quickly (no, it's not due to local water which is fine, something I had to prove by going to the relevant Minister); that I will probably have to replace the sacrificial anode every 3 yrs due to excess scaling, which increases the running cost dramatically; that the unit is not fit for purpose in Australian conditions and should be replaced with a more suitable model, or my money refunded. I am also concerned that the interruption to the Legionnaire Cycle during hot weather might mean the water is not being properly treated, which would be a public health risk to users, and intend to follow this up with my local health authorities.

Good water heater and economical – Purchased in 2018 and the water heater has been running well for 4 years. At times, the hot water runs low in the evening, but only if a bath has been run plus a shower or two. So, it is definitely not suited to a large family... we are a family of 4 and it is usually fine with the occasional luke warm water (in Qld so only in winter). Show details
Very happy with the product – Bought the Bosch 3000 second hand, from a place the plumbers get trained to install heat pumps. 2 years in operation now, on ControlledLoad circuit, is SA, meaning the system gets arbitrary turned on and off twice in 24hrs. The controller deals with the on/off no problem. For a while the compressor was giving some squeking noise, however it… Read more
stopped without any intervention. Otherwise the heat pump running noise not a bother, our unit is placed next to kitchen window.
Excellent system, economical, very happy with it – Has been running for 2 years in a cold climate. Has worked really well. Wasn't too expensive. Is easy to program and monitor once you get the hang of the instructions. Not too noisy (although I wouldn't put it near a bedroom window if you use off-peak electricity). Show details
Negative reviews
Didn't last 5 years – When it worked it worked fine, a bit noisy, but gave up after 5 years, was repaired 12 months before it finally packed it in, hard to get parts for and very few people will service them. Show details
Waste of Money – Purchased it in Apr 2017 and in the period of 4 years, had it repaired twice under warranty and twice out of warranty. Heating of the water during winter is bad. Won't be buying another heat pump or any Bosch HWS again. Show details
Five years old and now failing – We bought the Bosch heat pump hot water system about five years ago and it has worked fine for the last four years until last year (twelve months ago) it has started failing .. as I am a licensed plumbing contractor I contacted Bosch Service and was advised to purge the unit and adjust the internal pump settings up from one to three. It worked… Read more
fine for another couple of months but now it is regularly failing to heat the water with any consistency. The only thing that works now (for about a fortnight at a time) is a power reset (turn it off at the isolation switch for 30 seconds) .. the unit then goes into LEG cycle. Having read all the reviews on here I am now thinking just replace it with one of the newer e.g., Rinnai Heat Pump units that have automatic purging; this is where the Bosch units initial break down problems appear to have commenced from by the need to keep running a system purge. I will just need to accept that the Bosch Compress 3000 (paid $3000 5 years ago) is at its end of life and move on. There is no doubt though that heat pump technology does save 2/3 off the cost of power when all is going well. The only problem with the energy efficiency argument in Victoria/ Tasmania is that you need 8 to 10 years of product life to justify the investment.

Good heat pump (until it fails). Clunky menus – This unit was used to replace a gas storage HWS and best utilise the output from solar panels using the built-in timer. It was easy to install and set-up with plenty of options, although careful reading of the instructions was required. It was best to learn what each function does and then work from the menu structure printed in the back of the… Read more
operation manual as the menu structure was not intuitive - for example, there are two submenus called "PROG" in the structure which can cause initial confusion! Apart from having to purge the heat exchanger twice (relatively easy to do) of air over a four-year period, the system had been reliable and supplied the goods. Unfortunately the system just dropped dead after four years - well, it did get out of the two-year warranty! A failed compressor was diagnosed with a quote of $2,600 to repair which means from a life cycle cost perspective it is more economical to replace the system in toto given that other items such as the tank and balance of the heat pump system have a finite life remaining as well as possible non-availability of spare parts in the future. Bosch Australia would not comment on compressor reliability, and it is notable that the product is not listed on their website anymore. Let the buyer beware.
Worst hot water system – This is the absolute worst hot wtaer system I have ever had the misfortune to own. Hot water temperature was always sporadic, hot in summer and cool in winter. It was difficult to program, often resting itself. Now to add insult to injury, two months out of warranty and it has broken down completely. Bosch proved very unhelpful.Will never purchase another Bosch product again Show details
2 year warranty and that's all we got from it – Programming proved very difficult followed instructions to the letter but only able to set it up to run continuously which was fine. Worked well for first two years , now has stopped working but out of warranty. Re Set it worked for a couple of days then failed again. Not happy will go for a unit with a much longer warranty in future. Show details

Continual failures and no Warranty from Bosch – We have had this Bosch 3000 less than 5 years and it a has always been a major hassle from the first hot summer and cold winter day, it requires constant maintenance, resets and it continually lets you down when you need hot water. It is unsafe occasionally spitting out boiling water and steam. It is totally unsuitable for Australian conditions… Read more
and fails every hot and cold day. I have recorded with photos over 50 different fault codes in winter and summer from the first year. It needs to run 24 hours a day so it has no energy efficiency. It has required new elements and anode in the first 2 years. The installer (Not the manufacturer) is always helping to get the machine running again after its continual failures. The poor installer is left to cover the repair to keep the customers happy. Bosch has said the machine is out of warranty and refuse to provide a repair despite the machine failing from new. If this is typical of Bosch Warranty you should expect the useful life of Bosch products to be less than 4 years.
So far, very happy with it!!! – 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… Read more
tricky to program, but once set, trouble free. Holiday feature works a treat. Would recommend this as a quality unit performing to spec...
I am happy with it so far – 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… Read more
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.
Heap of JUNK – 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'. Show details
Expensive piece of junk – 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. Show details
Poor after sales service – I purchased the Bosch heat pump 3000 270 litre in 2015 when looking for an environmentally friendly solid option for my new home. The product has been efficient until early this year (less than 5 years). However it has been expensive to run. The after sales service has been poor. I phoned Bosch after installation the product to ask if the product… Read more
required servicing and a few other general questions as I couldn't contact my plumber. The individual I spoke to was loud and rude and said he wouldn't talk to me because I wasn't a licensed installer, which I found poor after spending 3000 on a Bosch product. So 4 years down the track Im told by a number of plumbers and service centers that they don't deal with Bosch anymore due to a) the difference in its system to other heat pumps and 2) Bosch are too hard to deal with. I have come home twice this year to cold water and have been advised by Bosch to contact a service agent. The service agent has suggested they replace they swap it over for another brand. All I want is for the product to work.
Bosch no longer bringing this unit into Australia – 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.

Very disappointed – Simply doesn’t work. Had probably three months of use before error codes started. Repaired twice and then got stuck on legionella function. Was told by plumber this was normal fast forward a few weeks we have enormous power bills way bigger than with our electric storage system. Still stuck legionella function but at least we have hot water.… Read more
Finally sick of huge power bills reset to factory settings after wading through instructions myself because no one would help. Now water doesn’t heat above 37 degrees - not comfortable for a shower and we boil the kettle to wash dishes. This thing cost us $3000.00 and we haven’t had 12 months of hot water. Really regretting this s decision. Now told we may need filters installed for hard water. Disgusting that no one mentions this possible issue when taking your money and promising a great service. We have to keep going through Bosch. I finally spoke to someone at the company which installed the thing - URECO and got someone who seemed to listen. Was hopeful we might get a good outcome - not so hopeful after reading these reviews.

Four years old and its cactus – We bought this unit four years ago to replace another heat pump that had worked very well. We had some teething issues with it initially having error codes this went on for several months before Bosch sent someone out to purge the unit. Then it went ok for a couple of years and this past year has been playing up again. As it is now out of… Read more
warranty, Bosch would not send anyone out or help us with the problems. I had thought that a company as big as BOSCH would stand behind their product but NO. They sent us a list of Bosh technicians but it was a short list and none of the technicians would service our area. I eventually got on to a plumber who was familiar with heat pumps although not the Bosch and he got us back on the road again with a new thermostat. A couple months later however and the heat pump is completely cactus!!! plumber had to bypass the heat pump and essentially make it into a normal electric water system just so we could get by a few days!!! My advice; If you are looking at a heat pump make sure it has good warranty, and that there are technicians in your area that will service the unit outside of the Warranty period. Extremely disappointed in BOSCH and would not recommend

Impressed and Happy – 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… Read more · 1
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.
Avoid at all costs – 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!!! Show details

So noisy – 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. Show details
Low Cost to Run, Very Satisfied – The unit has been installed for a year. Long enough to be ready to review it. We chose this unit to remove our need for natural gas heated water. We have a 5kW solar panel system and I programmed the Bosch to run while the solar system is generating power, making it very cheap to run. Programming the setup had the plumber stumped, though the… Read more
install was easy as we positioned it near where the old gas unit had been. A sit down with the manual and a thorough read-through and I had the system running as required. A couple of adjustments to the programming since hasn’t required the manual to achieve the result. The menus are a little obscure, though after a few tries using them it all comes together. The unit has run flawlessly since. It’s installed in the Upper Blue Mountains, where the daytime temperatures typically reach the low teens in winter. The water from the system is used mainly for at least 3 showers daily and cleaning the dishes the dishwasher doesn’t do and has run out of hot water once, because I’d set the program for too short a cycle to heat the water, therfore not the heater’s fault. It may struggle to supply enough hot water on demand for more than 4 people, unless the boost is set on the menus. Because the unit is a heat transfer unit (aka an air conditioner compressor) there is some noise, which I expect if it was installed near windows / outside doors, the sound could be noticed. We installed it where we only notice a low hum in the house near the unit. Would we install one again? Yes, if we moved house, or needed to replace this one with another if we stay where we are long enough for it to wear out. Overall, we’re very satisfied.
5 Year+ Update...The unit continues to run flawlessly.
Bosch Hot Water Heat pump very good – 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.

Energy bill savings – 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. Show details
Works well with big savings on bills – 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… Read more
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.
Runs out of hot water – 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 Show details
programming – 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. Show details
having trouble programming the system – 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. Show details
Great system to use with PV Solar – 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… Read more
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.
Thank God for Bosch – The town house that I bought had an instant hot water system..1st quarter $350. 2nd qtr $510. 3 rd qtr 816. YIKES Bosch 1st qtr which includes 3 weeks with the instant hot water....$206. Everything I read about this system is true..the only negative thing I can say is that when I rang Bosch c/service for more information, the person i spoke with knew less than I did & wasn't interested in helping.
