-Decent output: can cope with two long showers in a row
-Temperature fluctuates often, meaning constant adjustment are required
-Pilot light goes out at the faintest suggestion of a storm (in Perth, where storms are very minor)
-Re-lighting the pilot takes many attempts, as the gas output on pilot seems to be very weak
Thermocouple keeps dying
The thermocouple for this appliance dies every 12 months or so forcing you to replace it at a cost of around $100, and which isn't always the easiest to find
Value for Money!
We had this hot water system installed by Ember Plumbing yesterday replacing an existing Bosch 10p which was over 14 years old. Cant complain with the old Bosch system lasting over 14 years. Value for money in mine and my hubbies option and fingers crossed we get another 14 years.
Purchased in March 2019 at Ember Plumbing and Gas.
Worst hot water system on the market
Every time we turn a tap on, no matter how close to the system, about 2 minutes of water goes down the drain before it is hot. After continuous issues with the pilot light going out, the ignitor button eventually stopped working completely, we enquired to get it fixed and were told it would be almost cheaper to replace the unit than have 1 button repaired. So i manually lit it for the next 15-20 times before all the buttons stopped working. Now i can manually light the pilot light but the gas-on button wont stay on. If someone recommends this product, dont listen to them, do not buy this product.
Should be called Tepid Water Unit.
Had a Bosch storage hot water unit for 15 years. No worries,hot water when we needed it. When it recently gave up the ghost were replaced it with the Water Wizard 10P. What a disappointment this unit is. We are alright if we have a shower because the shower is about two feet from the unit. If we then move along three feet and try to get a basin of hot water in the bathroom we end up pouring a lake full of water down the drain in order to get a basin full of tepid water. If we then want to fill the kitchen sink (which is more than twenty feet fr...om the unit) with hot water,well forget it. We end up boiling the kettle and filling the sink with that. I wouldn't give you 2p for the 10P it's an ineffectual sub-standard piece of rubbish. I think that in regard to this unit Bosch should rename themselves Botch. Not happy.
Buyer be aware all made in China
Yet to find out how these hot water heaters measure up... thought they were made in Australia as before under licence. Australian made lasted twenty years plus...and very reliable... the outside packaging very misleading mentioning Germany and Gb Technologies... nowhere on the outside packaging does it say made in China... you have to look on the inside compliance plate to find this out. Not even on the Bosch website does it mention where they are made... Buyer be aware you are not buying a German product even the insides look very different than past models...
Very Disappointed Mr Bosch!
There is no doubting that my Bosch hot water system produces plenty of hot water. (Our system has the gas pilot light for ignition)...BUT...it is terrible for showers. If the hot water requirement were for a kitchen or laundry or even multiple users at the same time it would be ok but for just one user trying to have a shower it is very disappointing. The hot water is so hot and strong that even though we have had it turned down as low as possible, it still needs cold water. No matter how you try and balance it, to get it to a pleasant temp...erature and not scald yourself, the volume of cold water required soon overrides the volume of hot coming through and turns the hot off so you alternate between being scalded or being frozen. The high volume of hot and cold together to keep it even still results in anything but a relaxing shower - it is like being blasted by a very hot Niagara Falls. The only way I have been able to over come the problem is to have the hot water tap running down the drain in the hand basin at the same time as I have a shower. This provides the volume needed for the hot to not cut out when cold is added. After all the money spent on this system, getting metres of copper pipe to it so it would be closer to the bathrooms, having the experts out to look at it, it has been a total and expensive disappointment. My daughter has the same system at her new apartment and I knew as soon as I stepped in the shower that it must be a Bosch so checked and was correct. If Bosch don't improve their game, they will lose their name.
Don't buy one
This is the first time I have felt strongly enough to write a review to help others. After another visit by the after hours plumber -
This is my second bosch of this type. Both have had the same issues starting in the first 12 months. Regularly not having hotwater is not nice. The parts don't last long, the pilot light goes out, the buttons get stuck so you cannot operate the unit, hotwater takes a long time to come through and the water cycles through hot and cold - even with the water saver removed in the shower head (they say it causes the hot cold cycling), wd40 to get the off button to unstick. The plumber had to really talk me into the replacing the last bosch with the current 10P and I hate to think what it has cost me.
Good product, cheap and reliable
we have two models the 10P and the 16P they lasted about 12 years each and we have replaced them with the same products. The heaters are located directly outside where they are need and the hot water flows almost instantaneously. no power connection required, so you have hot water when there is a power cut. my only criticism is that they quite deep and stick out from the wall - could be wider and less protruding. effective reliable and good value.
Terrible Hot Water System
This hot water system is simply terrible. It always takes an eternity for the hot water to come through the taps. In my shower it is difficult to mix the hot and the cold reliably, the basin tap won't mix hot and cold at all and the same with my kitchen taps. It provides really hot water when the hot water does come through, however it is almost impossible to mix the hot and cold to get a warm temperature, when you add the cold the temperature of the water becomes cold and there is no warmth in the water. I don't know what to do about this problem. Gone are the days where I could just enjoy a shower.
The idea of hot water on demand is a good one, if that is what you get. You're not going to get a great flow from this product but it is adequate when it works. The main issue with the Bosch 10p is the pilot light keeps going out and won't stay lit. The initial signs are 1) it goes out 2) you have to hold the pilot light button down for several minutes, not 10 seconds to reignite it 3) then it won't be too far down the track that you can expect the pilot light to just not stay on at all no matter how long you hold down the button. We have found out it is the thermocouple, it has a very short life, we seem to be replacing ours 1 to 2 times a year, very annoying.
It's with heavy heart that I admit that I was wrong after calling the Bosch recommended number I was told that the cost of a service/diaphram replacement would only cost $190 after being quoted $300/$400 by local plumbers who seemed more interested in trying to sell me a new one ,so thanks Bosch ,so I would say google your local Bosch service centre ,you will probably find it is actually cheaper believe it or not ,the tech also recommended having this done about every 2/4 years and the system will prove to be a good buy .
Bosch 10 P water heater
I've had this a year now. I gave up using it to wash up, and just boil a kettle - it's less hassle. Showers are still a problem - it's easier to run a bath.
When I changed over the gas bottle, I could still cook with gas, but had no hot water. Cost me $110 for a plumber to fix. He has shown me what to do next time, but it shouldn't happen.
Basically, Bosch has made a product that just does not work well with bottled gas. It's OK with town gas, but otherwise too many problems.
Huge waste of money for me.
Jan...Fairly inexpensive See above
Agree with the posts above. I couldn't afford to replace my solar hot water system, so went for the 10P. Haven't had a decent shower yet, and I have to boil a kettle to wash up. Changing to a different system cost me around $1500.
It wastes 3/4 bucket of water before it gets 'hot', so impossible to use for small quantities of water. The plumber has already been back once, and Bosch say if they send a technician I will be charged if the damn thing isn't actually defunct. On an Aged pension I don't have any more money to spend, so what to do? ...I'm very unhappy with this product. I should mention that the heater is below my kitchen window, so water doesn't have far to travel. Next step may be the Ombudsman. Too many people have the same problems with this product to ignore. And maybe a report to the Water Corporation. Relatively inexpensive Wastes water. Goes cold after a minute. Takes too long to heat up
Six months ago I took the time and trouble to give Bosch my earlier Thumbs Up review thingy here.
Look, what I really had in mind back then, was to approach Bosch and ask them to magic up a good price on the replacement unit.
Well Fair's fair hey! Yep, always reckoned one good turn deserves another.
So ... having given 'em a decent report here, went over to their website and filled in their stoopid online enquiry form with all the details.
Totally ignored. Not a whisper!
Ok. So, benefit of doubt, 2 weeks later (assu...
Isn't it nice when it just works
I read many reviews for a replacement gas hot water heater and comments were all over the shop. This is one time when I made the right decision. I was pressured quite heavily by sales to migrate to the zero pilot systems. We have both pump assisted or gravity fed tank water and I was concerned there would be enough pressure to turn the pilot on. I was also considerate my bbq takes a few prods. So I went with the Bosch 10P. After I bought it and installed it, I was told by 2 independent installers that the zero (on demand) pilot systems were a headache for many and they were getting many calls and THEY told me I had right a wise choice. I have never had a problem with the 10p. Excellent unit - built to last.
