Works well. 50 degrees because that's the law. A while to get hot water coz that's the house plumbing. Once going constant pressure using tank water. No other first world's problems here.

Just replace the old 170L hot water system by Rinnai B26. It is compact and powerful. 2 person shower at same time at 2 bathroom without any problems. Much better than the old one.

Had a new b26 ibstalled in a new house. 5 days later no hot water. Unit is not switching on. If i turn the gas and water off at the unit then turn them back on the unit produces heat fir about 20 seconds then goes cold again. Very unhappy.
Update: Rinnai sent a plumber out promptly and fixed the problem.

This was recommended and installed by our plumber.
We have massive issues every winter when hot water suddenly stops while in the shower, customer service is useless, when techs come to check, unit works fine so they can never point out the issue, we're at loss. We always thought we got a bad unit never realising so many people have issues.
Extremely unhappy.
Don't know how to get a resolution, the only option might be to change the unit and fork out more money. What a waste of our precious water!

Since we’ve had this system it has never worked properly especially in winter (although occasionally in summer). Getting hot water to run is close to impossible. It involves switching off system and back on multiple times to get some hot water before it goes cold again after a few minutes. Very disappointed

Just had my house built with one of these and im very unhappy, it doesn’t heat up enough to wash the dishes,the water comes out just over warm, I can put my hands in without even putting any cold water in and doesn’t even feel uncomfortable, I have to boil the kettle to get my dishes clean, I shouldn’t have to do that its brand spanking new, if i had known that it would be like this I would have payed for something better, I seriously want my money back and the money it costs for the installation

Had a rinnai b26 installed about 8 months ago. All going well but now we are having morning frosts say -2 no hot water until 9am. All pipes wrapped , pipes freeze but not affected unless much colder with old storage unit. Bottled lpg gas system. Any ideas on how to fix, very annoying

tried to contact Rinnai service department as my B26 was making noise.Waited over twenty minutes before a guy immediately tried to put me in for a service with service department.Waited another fifteen minutes and gave up.A service!!The unit is one month old.....ridiculous.......never again.

A lot of cold water is wasted waiting for the hot water to flow through the taps. Very disappointed given we consciously make the effort to minimise our water usage.

Just had a Rinnai 'instant hot water service installed as people told me it would be preferable to the larger tank heaters.
Seriously wish I'd gone for the larger tank style.
Hot water takes forever to come through.
I now turn the tap on then go & do something else, meanwhile copius amounts of cold water goes down the drain.
When a tap is turned on, the water pressure drops right down then surges back.
I've had a plumber check the gas pressure & it is fine.
Looks like I bought a dud.

Pathetic.

When you turn off hot water the rinnai 26 emits a sound like a bomb falling from the sky. It's a high pitch whistle which rinnai reckon was a batch of noisy fans, so they replaced the fan, no change just as noisy.
Spoke to a neighbor who has a rinnai 24 , no problem, quite all the time.
Neighbor next door has a rheem, same quite.
What will I have to do to get some peace and quiet from the missus over this damn noise.
