I've only had this in for a few weeks but already I'm disapointed with noise it makes. It seems to pulse when on and it can be easily heard upstairs from it. For the money I thought it would be quieter and now I'm concidering going back to electric.

1 rubber ring replaced, working again now.
Stiebel sent a very nice pair of service technicians to repair a rubber seal that was leaking, at the earliest opportunity...they reassured me of the quality, longevity and cost effective benefits of the 302...now I have calmed down after having no hot water for the weekend, I can say that the service was quite good, they took the time show me some cleaning tips to increase the longevity..looking forward to a warm shower...

Stop press - stiebel have replaced it hooray - Fails at least once a year since year -
We have lived in this unit in Canberra since 2017 where a large number of Stiebel Eltron heat pump hot water heaters are present in the unit complex. Every year we have experienced a failure of some sort, where the hot water goes cold as the unit no longer operates. We have had plumbers out, many are not familiar with this type of heat pump hot water heater. Stiebel never appear onsite, they only offer phone support. I will imagine I will put a call in tomorrow and they will say it is outside its 2 year warranty. I will have to say it is a “Maj...or Failure” and will pursue statutory warranty obligations. I have had a traditional hot water heater in an investment unit, I have had no problems with it and it was installed in 1999. Over 20 years of trouble free use. With the Stiebel Eltron I have a failure every year for 3 years and have had 5 or 6 call outs to get it fixed. I would never buy one and if I was looking at another investment unit to buy I would not buy it if it had a Stiebel Eltron.

Usually no hot water
Just buy it least 1 year. I think It is not good enough. Always stop work and no hot water. I need restart it every day. If not, I will no hot water to use on second day.

The reviewer stated that an incentive was offered for this review
Still going strong 11 years on!!
Installed in 2008, replacing old electric storage unit. We have a family of 5 and ran it on a timer from 9am to use the heat of the day and it will only run for around 2 hours max in the coldest party of winter. Always had plenty of hot water. Cost around 50c a day to run as it will only need an hour to reheat in summer.
We have since moved to a new house in (2016) with gas h/w and I’m just about to get another Stiebel electron to replace it to save on the $1200 a year gas bill.
In short it has been a great investment and I highly recommend this unit.

Great Heat Pump
Had the WWK302 for a few months now, very happy with unit. I was actually quite surprised how quiet it is, I'd say about the same as a pedestal/desk fan on low/med speed. Power consumption is about 600w & normally runs for about 4-8 hours per day. I do have two issues with it, one being the size but being 302L not much can be done about that (issue is more I did not provision for such a big HWS when building). The other issue is there is no timer/controller, so you will need a external timer to take advantage of solar production or off-peak tariffs.

Very happy indeed
I deliberately waited a few months now to write this review to be able to get a better understanding of this unit. Before the purchase I read all the reviews for the previous model (the 300) and I was a bit worried about the many negative reviews. I found an online retailer (not sure if I am allowed to mention this here but I try it anyway. They are called "Enter Energy and Water Saving Shop") and the gentleman there (Gary) was a treasure of knowledge that he was more than happy to share. He very much recommended this newer version heat pump an...d I can honestly say that I could not be happier. It runs amazingly quiet for starters. I have it installed under my house and one of our bedrooms is only one single brick wall away. When the unit runs, a slight hum can be be heard in that room but only when everything else is absolutely quiet. We are a family of five and I have measured the electricity usage of the unit for the past 97 days with a Watt meter (February to May). We used a total of 210 kWh or 2.2 kWh per day which means that since I run it on a timer at off peak rates only, we pay just under $100 per year for our hot water. In comparison, my old electric system (stock standard Rheem) which did not run on off-peak rates only and did not have a highly efficient heat pump in it cost me around $700 per year to run. The unit cost me $2,570 after NSW rebates, the approximate $600 savings a year give me a 4.3 year payback time - tax free. That, in investment terms, is more than phenomenal.

Stiebel Eltron Product and Company Integrity
We purchased and WWK 300A model heat pump exactly 6 years ago and it has run faultlessly until last week end when it stopped heating water. After a service technition recommended by Stiebel Eltron in Perth looked at he pronouced it terminal due to a gas leak inside the heater tank. As it was one year outside of the warranty period I was not impressed and contacted Stiebel Eltron Australia. Their response was what we all hope for in these situations but rarely get. Luke from the service team got back to me within the hour and offered a new W...WK 302 heat pump at no cost to us other than the installation cost. The water heater was delivered the next day and installed today. I can only recommend this company and their products. Not everthing can be perfect - it how a business responds when something goes wrong that is the mark of their worth.
Great product - Great Service
When planning to build our brand new home, we researched the for best Hot Water solution and ordered a new Stiebel Eltron Heat Pump. We wanted a reliable and efficient hot water supply. We received great service and advice and our new heat pump was delivered on time so it could be installed when the builders required it. We have now been in our new home for about 2 weeks and are very happy with our decision. The Stiebel Eltron Heat Pump is super quiet and delivers plenty of hot water.
So far so good!
We needed to urgently replace our hot water system with an energy efficient electric system. We have solar panels and after much research came to the conclusion that a heat pump was the most cost and energy effective solution for our set-up. Dan at Stiebel Eltron was very helpful. We purchased the heat pump through retravision commercial Osborne Park who gave a great price (much cheaper than competitors). We always have hot water, it's quite quiet (located behind our laundry) and our electricity cost has come right down to not much at all. So far so good!
Awesome water heater!
We needed to replace our faulty solar pannels and the pump in the tank.The solar has been nothing but trouble so acter doing some research and getting a recommendation from a friend we decided to go with the Stiebel Eltron WWK302 system.
The install was done with minimum interruption for us and so far it's been great, hot water when we need it.
Worth mentioning that on some reviews that I read people were concerned about noise from the pump, yes you can hear it but it's a quiet hum that hasn't bothered us at all.
I've recently installed 6x Stiebel Eltron WWk-302 units at various locations.
Compared to the new units they are so much quieter, and no complaints from the clients.
We have also complete a few solar hook ups, great option!!!!! Simply and easily done, great selling point for some for clients who have are going to install solar panels.
Questions & Answers
What is the normal electricity comsumption over a 24 hour period?
Dear Ian ,
Very good morning to you.
Thank you for your message.
Power consumption of a stiebel eltron depends on your usage. If you are comparing a stiebel eltron heat pump with a standard electric tank. Normally for a replacement at same house its 80 % less power consumption .
Hopefully this helps.
Have checked with Stiebel Eltron and below is the reply:
The average daily consumption on Tariff 33 Energy Bill is 1.9kW
We are a household of 5 (4 of them female, I feel I need to mention that :-) ) with a WWK302 in Sydney. The geek I am I have installed a Watt meter on my unit which has been measuring the electricity usage for the past 97 days (1 Feb to 9 May). Total usage is 210kWh which makes 2.16kWh per day. So, multiply this with your electricity price (average is around $0.22/kWh) and that gives you a cost of abut $0.45 per day to run. Note that this period is the warm weather period in Sydney, so I would expect the consumption to go up as outside temperatures drop (less heat to pump from the surrounding air, cold water inlet temperature lower, hence more energy needed).
I have three different rates, peak, shoulder and off peak and I run my unit on a timer to only kick in after 22:00 when my rate is $0.12/kWh which results in about $0.26 per day or just under $100 per year. Hope this helps.
