Piece of Junk!

Installed by licenced plumber day 1 and didn't work from brand new. Have had multiple call outs to repair over 4 years of use and has let me down on Xmas day 2021 with a house full of guests. Absolute rubbish!

Save yourself the time and money and but something else!

Wish I had seen these reviews before I bought this lemon

We built our new house 5 years ago, the unit worked ok for the first winter (we shifted in late July, live in North Queensland and do not need hot showers in summer). Every winter since we do not get even warm water, have contacted Rinnai before and they told us to contact the company we bought unit from, have had them to look at item and they cannot get it to work any better, there are only two of us in the house so this unit should be able to keep up with our usage. We have not been able to have a WARM shower for 4 years I am fed up with it but cannot afford to buy a new unit.
Do Not Buy These Heaters.

HOTFLO 10 - Rubbish!!

Had nothing but trouble with this water heater, since installed by a Licensed Plumber. Had numerous callouts, and now the water is lukewarm at best. Tried everything. It's definitely not the water or gas pressure as both are excellent. New battery and still the same old problem. Call a technician and pay $300 just for a call out. Do not buy this product, it is absolute rubbish. Show details

What a dud

We had the Hotflo 10installed in March 2015 and by November 2016 it was subject to a warranty claim, no hot water at all. Subsequent to that claim the system worked until early 2018 at which point it started to play up, no warm at all or lukewarm. We spent a fortune thinking it was batteries. Our water flow is from a large rainwater tank delivered by an excellent pump so pressure is not the issue. At time the system just went on strike. It stopped all together last month for a few days, so I decided against repairs, and have replaced it with a Bosch system, same flow rate and with the added bonus of not requiring any power for ignition, it’s a hydro system. I still have the old Rinnai unit if you guys want to have a look.

DONT BUY !!

From the day it was installed the water was just warm..Ive had 4 gas plumbers out & the ATCO gas supply guy out(who advised to remove the green tempering gauge which cools the water to the Govt advised temp)..He even changed the regulator at the gas meter, increased the gas press..so with all this done, its still just warm, & the warranties just out..the bathrooms are nearby,but nothing brings the temp up...the ATCO guy said hes seen 4 other complaints with this new model....avoid at ALL costs...go to solar with elec booster & solar PV panels

This hot water service has given us nothing but trouble since it was installed 18 months ago. Hot water in this house is something of a memory only. It is useless & the amount of water we've wasted, waiting for hot water to come through, is ridiculous. Do not buy

This HWS is described as Instantaneous unit, while other Rinnai HWS is 'Continuous Flow Hot Water', what is the difference between Instantaneous and Continuous Flow Rinnai HWS?

All 1 star bad reviews, can anyone confirm if this unit has been made in Japan or other countries?

I remember all other Rinnai Continuous Flow HWS including builder series B16/B20/B26 are made in Japan.

No idea where it is made but it broke 14 months after I had it installed so regardless of manufacture location, it was faulty

Could anyone please let me know where the pilot light is on this system. Have no hot water and figure this may be the problem. Have had nothing but problems with this system.

Thanks
