Do not buy this product
Bought this product to replace an old gas hot water system. My plumber took it out of the box and went to fit the regulator and the pipe sheared clean off. Both of us were stunned at how brittle the pipe was, it seemed porous.
We have been given a complete run around by Rinnai customer service and their hopeless Sydney Service provider D&N plumbing. We were told our case was a priority case to be actioned but I never received any call and have spent the entire day chasing them to get someone to come out to fix the faulty product. We received ...Read more
no call from D&N plumbing and they have just ignored our calls. We've had to continually call Rinnai to try to get this fixed but have been told to wait another 3 days as they will not pay the call out fee for D&N plumbing. I cannot stress enough how much we regret ever having the misfortune of dealing with them and this faulty, dangerous product. Save yourself the hassle and stay well clear. I wish I had seen their reviews prior to buying this product. Hopefully this review and the other ones will save someone the hassle of what we are going through.

Thanks, Rinnai AustraliaThe plumber that you guys sent over had no idea what to do.. He couldnt fix it.. Spare parts are way too expensive just to see if it fixes the problem.. We will need a new service.. Not a Rinnai again.. rubbish product.

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.

This unit is supposed to be for off grid installation.
Installed less than 3 months ago.
We have our gravity feed tank 20 metres above the hot water service - I can shoot a 50mm stream of water more than 5 metres in the air from the pressure we have - however the hotflow barely puts out 30% of the pressure of the cold water line - which is identical. It is not designed for anything other than town pressure - a complete fail for its design.
Also - yes - you don't get hot water, you get warm water at best. We have a $200 caravan hws off ebay ...Read more

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

Rinnai Hotflo
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 is Rubbish with a capital R
I will start by saying that we have 4 Rinnai constant flow gas HWS, 3 of which are excellent; the HOTFLO 10 however is Crap! Rubbish! It has NEVER worked! We got it only because we are in an area with constant power outages and it is battery ignited, that was the idea anyway. It should be called the Luke Warm Flo 1 or the Cold Flo 0.5 because it simply doesn't work! We have had the Plumber back 4 times and Rinnai out twice. It is serving only one outlet, the kitchen sink / Dishwasher and I cannot recall the last time I got even warm water from ...Read more
it after 10, 15 or 20 minutes. It will be replaced as soon as I have installed a Standby Generator to eliminate the need for battery ignition. And it will be painted Yellow and put on a pole out on the main road with a LEMON sign. DO NOT BUY ONE OF THESE PIECES OF APPALLING RUBBISH - THEY DO NOT WORK AND RINNAI DON'T WANT TO KNOW - YOU WILL REGRET IT! David Jones 04381068681 comment

This unit is installed in a remote area and does not get a lot of use. In the 6 months I have had it it has only been used 20 or 30 times, Now it has stopped working. Plenty of waster pressure going into the unit,full gas bottle,new battery. Can anybody tell me what to do. The unit was reccomended and I thought I had made a good choice,but maybe not,
Any clues ?.

IF totally buggered it should be under warranty (1300555545 Rinnai serv no at least in WA)
ours is working ok now that we turned the water flow & temp adj clockwise to decr water flow AND my plumber removed the Govt required Temp Limiting device which most plumbers say is the problem if water not hot enough/( nanny state... put in.so babies dont get scalded)
ps..when my solar panel rebate finishes in 4 yrs, I'll be cutting off all gas to house, buying the biggest storage batt & solar hot water elec boosted)
We have since got it working 95% of the time - we had to completely open up the gas regulator which the manual says must be installed (plumber showed me how) and we have to be very careful of air bubbles inside the hot water system (requires draining of the HWS on the inlet side to try and fix). Also I highly recommend removing any flow restrictors on any taps/shower heads You want to ensure your water is flowing at more than 4 litres per minute. I did this by placing a bucket under the outlet, turn on hot water only and see how much water goes into it over a minute - a bucket is usually about 10 litres. You need 4 litres for the HWS to attempt to warm the water. The Temp limiting device might be a factor if there is air bubbles in the HWS - however we still have ours as set up and in summer the water is hot, in winter it is just warm, we are considering setting up a pre-heater for the water before next winter.

Thanks for the question Scott, it can be hard to provide a diagnosis without examining the unit. We do have a technical help line who can troubleshoot over the phone and arrange a service call out if required. If the fault is a manufacturing issue, you are still within your warranty period for the unit.
