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

Rinnai
Rinnai   DM   

Hi Polly, Thanks for the question.

The Hotflo 10 burner lights automatically when the hot water tap is opened, and goes out when the hot water tap is closed. This unit does not have a pilot light.

How often should I release the pressure valve on my unit and for how long should it be released

Rinnai
Rinnai   DM   

Hi Sharon G. The user should operate the easing gear of the ECV and PTR valve (if fitted) every 6 months as described under
“Safety Devices” on page 6 of the Owner's Manual.

Hot water Flows from the pressure relief valve continuously. is there a way to remedy this?

Tony F.
Tony F.  

Open and shut it a number of times in case there’s a bit of foreign material on the seal. You should open and close it a number of times every six months. Other than that it may need replacement. Hope this helps.

hi - I have the same problem as above. Stupid question but do I switch the unit off to do this or do it whilst it is on? (mine is a hotflo 135 (gas) if that makes any difference). many thanks

Rinnai
Rinnai   DM   

Hi Den, Thanks for the question.
It may need releasing manually sometimes a bit of gunk can get caught under the valve. If it is an older valve it may need replacing.

Please contact our service team on 1300 555 545 for booking or alternatively you may book online following the link provided; external link

Hi
Rennai Hotflow Hot water system was installed by a plumber in May 2013. It started dripping slowly a few months ago and now increased flowing continuously from top of the cylinder! I read that Cylinder has 10 year warranty/ 7 year labour and could you please advise me what is the next step! Thanks

Rinnai
Rinnai   DM   

Hi Jay, thanks for the question. Booking a service call so we can diagnose the issue with the unit would be the next step.

You can book the service call online here and you will be contacted by the technician to book an appointment:

external link 

The current warranty for the Hotflo unit is 7 or 10 years depending on the size of the tank and 3 years labour warranty. The warranty applicable for your unit will depend on the model number and date of manufacture and can be confirmed in the warranty booklet supplied with the heater or through our service line on 1300 555 545.

Thanks

Hi
Yesterday I contacted 'Rams' plumbing Toowoomba(installer) and was advised to contact Rinnai with model/ Serial # (model is HFE315 ?SSL? and S/N is EHF31500468)
If you could confirm what is next step is? What I want is not calling a plumber/ technician who charges couple hundred dollars and and say 'you have to replace' the unit!
So appreciate very much if this unit (model is HFE315 ?SSL? and S/N is EHF31500468 )which was installed in May 2013 is covered!

Best regards
Jayantha

Hi Jay, Please contact our technical help team on 1300 555 545, option 3 to determine the correct warranty for this unit. The can have the service team book a service call which would be required to determine if warranty is applicable.

Thanks

Hi, It was really misleading that you confirmed that 315 litre unit is covered under 10 year warranty and now you are saying that this model has only 5 year warranty? , also we regret that you also have advised local agent ( who came to do 'unit inspection warranty check' ) to charge us the service cost; but when I explained to 'plumber' what I said to you and how it happened, then he has contacted Rinnai; Now Rinnai has agreed to cover that cost of service! BUT the question is it I was informed that unit is not covered under warranty , I could have simply called plumber and got it replaced last week without any hassle! I preferred/ prefer 'Rinnai' as it is excellent' Japanese technology ! BUT unfortunately it lasted only 5 years , i.e. around 300$ just for unit> which we could have bought hot water easily from elsewhere when added the electricity cost! ''<<< Is it a fair/ justice resolution from Rinnai>>""" I am not a happy customer even though I have decided to go with Rinnai (due to Japanese technology) 315 Hotflow again to replace the faulty/ failed/ cracked unit!!!

Jay
Jay  

See below what Rinnai sent to plumber!
Afternoon,

Unfortunately l actually didn’t pick this up but FSU has declined this as it is a 7 year old unit and warranty is only for 5 years so this job is chargeable to the customer.

Thanks I replied to that; sad thing is that we has solar electric hot water system which failed in 6 years in 2013 and went for a better Japanese Rinnai product to replace BUT it failed in 7 years .. this goes on... just costing money: I believe if any hot water system which doesn't last at least 10+ years is NOT acceptable!

I purchased a Rinnai 125 HOTFLO water heater less than 18 months ago and had it installed by a licensed plumber. Yesterday I noticed it is seeping water out of the cylinder bottom circumference seam and causing that seam and small nut to begin to rust. I have called Rinnai today and had to wait so long, then spoke to a technician, who said this definitely should not be happening, and the cylinder is still under warranty. He re-directed me back to the "bookings" switch, but I never got answered. I request that I am called back urgently, before this problem gets any worse. I had my previous water heater in the same spot for 15 years without anything like this happening. From above reviews it seems like this system has problems. Either way, I want Rinnai to fix this problem. It is definitely a product fault.

Dear Rinnai,
I have received the email and when I click on to the website https: the form does not eventuate, the page just continues to talk about conditions and costs. So I have then tried to get the form on CONTACT. This gives me the form, but when I try to enter my NAME etc. the form disappears! What is going on ? Please contact me again through my email and I will give my private phone number so your staff can contact me personally.

Hi - I have a Rinnai HOTFLO electric water heater purchased via Origin about a year ago, model HFE160 (160 litres). It works fine but the thermostat setting is too low by a few degrees, the water is warm and not hot, something I'd like to correct now that it's winter. It takes about 5 minutes for warm water to come out of the kitchen tap when is should be hot, the shower water is warm but was not a problem in the summer. The only question I have is how can I as a user increase the temperature setting without having to arrange a serviceman to come do it at a cost. I live in Oxley Brisbane 4075. Thanks. Peter

Rinnai
Rinnai   DM   

Thanks for the question None. There are unprotected electrical connections and no user accessible components so a suitably qualified person is required to make the adjustments.

I have a rinnai16 and it has been nothing but a big mistake. It is not that old and i have already had people out 7 times to fix it but with no luck. It will draw the water through you can hear it ignite then cut out and no hot water. Any help?

Rinnai
Rinnai   DM   

Thanks for the question Mel, have you had a Rinnai technician inspect the the unit? The most common cause of a unit cutting out is a lack of gas to run the unit. We would like to investigate this for you, can you please send an email to enquiry @ rinnai.com.au (removing the spaces) mentioning Product Review and we will have someone contact you to discuss.

Tara Rymer

We also had nothing but trouble. If it is under 12 months old I suggest contacting place of purchase as it should be under warranty and/or contact email given above. We had our Rinnai replaced with a Thermann and have had no troubles since. Good luck hope you can get it sorted soon I know how horrible it is to have no hot water, especially as it approaches winter.

J C Deep
J C Deep  

Sorry dont know about that model.

With mine -

Battery - The Rinnai idiots designed it with one "D" size battery - not enough - should be designed with 2 so more reliable like my chinese "camping" HWS - finally found a battery good enough and it lights everytime.

Gas - make sure the regulator fitted to the HWS is not too resrictive - If there is an adjustment on the regulator like mine then open it up and try it.

Flow - make sure the flow is consistently over 4 litres a minute - get a bucket (10 litres) and see how much of it gets filled in a minute.

If flow is to slow - remove flow restrictors on shower heads and taps (plastic fittings on the end of taps - for shower heads usually where the shower head connects to the wall).

I considered buying a non-instant model - as there is no delay with heating the water.

Thanks for your reply. It is electric start and costing more money than it is worth. I have had 7 different people look at it but they all say i can not see a fault and these hot water services are great.

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)

J C Deep
J C Deep  

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.

Rinnai
Rinnai   DM   

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.

Ann
Ann · HOTFLO Electric Storage

After receiving our latest Power bill we went "Shock horror" at the increased amount of power our hot water usage was. We have a 400L Rinnai Hot flow Storage heater that is only 18mths old. There are only 2 people living in the house. In the last quarter our usage has increased by 2000kwh, from 347kwh in the previous quarter to 2343 kwh. Something very wrong here. My question at this stage is what happens if the licenced installer has connected the wires the wrong way around, even though it has worked fine, would this cause a higher power consumption over time?

Rinnai
Rinnai   DM   

Thanks for the question Ann, there could be a number of issues that might increase the power bill, have you noticed any water leaking from the tank? We have a technical help line that might be able to run through some troubleshooting for you, they are available Monday to Friday from 8.00am to 5.30pm.
