Saves on gas bill but requires running tap hard to get hot water
I'm pretty sure we bought this around May 2018, and after getting it, I really really missed my old one.
Our plumber recommended this one as he used it for his home and he liked it. But I think it comes down to the way that I use my water & tap. When I’m washing dishes, I run the tap 30-40% flow strength, and doing it that way, the hot water system doesn’t get triggered, so no hot water (even when I’ve got my tap on only hot water). If I run tap harder (60-80% flow strength), the hot water will get triggered, no problems. If I run tap 40-50% flow (Hot water setting), it may get warm water for a minute, then goes cold.
So basically, I got used to freezing cold hands doing dishes during winter months (and the 8 degree mornings of Melbourne spring days) as I don’t want to waste so much water just to get the hot water going.
Hot water for our shower is good as it’s closer to the unit plus we’ve got lots of water flow so no problems there. Though water does take longer to warm up than my previous hot water system, so when I’m getting the temperature right for my child, I have had to collect the excess water used (before it warms up), for the garden so it’s not wasted.
So it comes down to how one uses their tap & washing dishes.
Incomparable improvement on my previous unit
After our hot water system started to leak we decided (on recommendation from a trade store) to install a Rinnai Continuous Flow Water Heater. When I received my first gas bill I thought it must have been for a lesser time frame as for 3 months it was only $96 - nearly half of the previous one. Apart from the gas savings, the water is much hotter and several appliances can be used at once without the water running out. I highly recommend these appliances. I could not be happier with our purchase. High price to start with but I think over time it would pay for itself in savings on a gas storage heater which we had previously.
Rinnai Instant Hot Water System B26
We're still having problems with the B26 instant hot water system from Rinnai. The water turns cold for about 30 seconds multiple times during showers. It is so annoying. We've spoken with Rinnai a number of times. The first time they told us to change the shower head, we did, didn't make any difference.
Then, they sent a plumber out from Jordans Gas Centres, who charged us $196.95 because they couldn't find anything wrong with the unit. We were told we need to change the regulator on the Gas supply line, because there wasn't enough pressure.
We did have the gas meter changed and pressure tested. The problem still remains - water still turns cold during showers.
I'd like to add that we are still under warranty. We have emailed Rinnai again with the whole story and I'm hoping that someone from there will actually take us seriously and try and solve the problem. I'm not paying another $196.95 to a plumber who tells me nothing is wrong, when something is clearly wrong.
Want warm water - purchase the Rinnai B26.
This system maybe satisfactory if it is located very close to the kitchen sink, the shower or other water outlets but if it is not be prepared to waste a lot of water before warm- (note that I have used the word warm) water is available -no need for any cold water or very little maybe when you shower. While you are waiting for the warm water to come through before washing dishes, fill up and boil your kettle - washing dirty dishes in warm water just does clean them properly. I would find it difficult to recommend this warm water system to anyone.
great little unit except for the sound
I have just had a Rinnai B26 installed and it's also making the same high pitched noise as mentioned previously by another person (see 11 Aug). The noise starts up immediately after you turn off the hot water tap. (it's not there while the hot water is running). The system is mounted on a bedroom's external wall and the noise is annoying. Not only can it be heard in the bedroom but also in the kitchen up stairs and faintly throughout the rest of the house. It seems to be travelling through the pipework.
I called Rinnai customer service and Ken advised that it's normal for the noise to appear after using the hot water tap as it's the internal fan cooling the system.
When I was contemplating the purchase of an instantaneous hot water system, I was worried about noise in the bedroom and was advised by the plumber that I wouldn't hear a thing. I expected a water noise when it's in operation like you hear from any tap, which is acceptable. But if I briefly use the H W tap during the night, the person in the bedroom receives 10 seconds of high pitched hum every time. Any assistance would be appreciated.
2nd Time I've had one - still excellent
We moved to a new home and replaced its ugly and expensive electric hot water tank with the Rinnai B26 and it is still an excellent product that was also inexpensive to setup and install. Never had an issue with the previous one which we installed in our previous home. This would be 5 star except for the little bit of lag getting hot water to tap (but it's not a noticeable difference to electric tank) so it's all about where you place the device in proximity to heavy use tapst. They are so cheap it's an option to have two if your house is long or large.
Difficult to replace a lemon
There were at least 3 separate manufacturing faults. The first was that the flame igniter was installed upside down and this was reinstalled the correct way. The technician refused to accept our suggestion that the unit should be taken away and tested properly at the factory. On the second call out (next day) the Rinnai service man claimed that the water flow rate in the shower was too low and that is why unit was cutting out mid shower. After some adjustment he told us that the fault was in the shower head. We purchased a new shower head however the problem still persisted. It was always clear that the flow rate was strong. Further the technician measures the water and gas flow rates at the unit and these were both completely adequate. By the fifth visit the technician installed a new control unit. The delay was due to the technician requiring to have the intermittent problem actually visible to him and not accepting our word on this.
With the installation of a new control we asked that the the technician wait and test out the actual shower hot water. He refused and ran out the door without properly ascertaining that the unit was working. There were two further call outs with final, the seventh, bringing the installation of a new unit.
The product clearly has failings and these are not easily rectified.
transitioned from electric off peak to hot water gasheating
We were very reluctant to be using a gas appliance as we don't have any other gas connections. After much researching we went ahead with the Rinnai B26. We have been very happy with the app. It has been reliable and providing almost instantaneous hot water with good water pressure, never running out and had a very good deal from Rinnai at the time. Only issue is if there is a slow flow the hot water cuts out so one has to have a good volume to ensure constant heating when taking a shower. This can be a drawback but one adjusts to this after awhile.Neat and compact installation by side of house was the other deciding factor for us. No regrets.
Amazing. Coming from Bosch 10P. This is amazing
Was confused as after reading all the negatives up here. People must be crazy to write these reviews, this is absolutely an amazing product.
Called my plumber the other day as my Bosch 10p started playing up and straightaway he said get a rinnai B16,20 or 26. And me being me picked up the best of rinnai with b 26 top model.
Absolutely right choice and loving it.
No more water fluctuations, no more waiting, it comes right away within 5-10 seconds.
