We have a brand new unit and we run out of hot water after 1 shower - how do we turn the thermostat up??

Hi Dirk, firstly, contact your plumber because he will know how to sort this out.
We have a tempering valve on the side of the hot water tank that allows you to adjust the temperature going into the house but that’s not going to sort out your problem.
Do you have solar panels or evacuated tubes connected to you hot water system?

Sunmaster Range

I have a Rinnai Sunmaster 175 solar hot water system installed at my property. The pump began making noises and when I contacted Rinnai a sub contractor come out, checked it and advised that that pump needs to be replaced and is not under warranty. The pump is only under warranty for 1 year! I was also charge for the subbie to come out even though the issue wasn't fixed. The entire unit is only 2.5 years old from new! I contacted Rinnai to enquire about the statutory warranty for all products and the customer service person was not sure what I was talking about. I have checked the Consumer affairs website and in general terms it should be covered under the statutory warranty but I cannot find an exact timeframe. Can anyone here assist? It takes Rinnai days to get back to me and I do not feel I should be paying this bill!

Sunmaster Flat Plate System

It happen always at night. Its only 2.5 years old with 2 pannel on roof. Should be covered in warranty or some one have same issue before. Thanks

Rinnai A.Rinnai

Hi Tej, we would recommend booking a service call to inspect the unit, whistling noise can indicate issues with the frost valves installed in the system. The valve are designed to expel water to protect the solar collectors during colder temperatures.

Steve F.asked

Sunmaster Close Coupled System

I have a Rinnai close coupled solar HWS with 2 collector panels about 10 years old. One of the panels is leaking from the inside. The is a condensation plume from about half way up from the bottom and when the water is turned on copious amounts of water leak from the base of the panel. I assume that there is a split in one of the internal tubes. It does not have anti-freeze or other materials.
I would like to try to repair it myself but there are no obvious assembly fixings ie no rivets, screws etc holding the panel together.
What is the best way to disassemble the panel?
If you do not have an answer from this website one of your technical people would know the method of assembly and therefore the disassembly process - please advise.

No your misunderstanding my question.
When the power came on we never had to do anything it automatically resumed it’s working order.
My question was if there is no electricity does the gas booster work or is it normal to have no hot water.

Sunmaster Flat Plate System

I have a Rinnai Sunmaster Flat Plate system installed in 1999.
What is the life expectancy of this system

3 answers
Rinnai
Rinnai A.Rinnai

Hi Nick.F,

Thanks for the question, in 1999 when your unit was installed Rinnai offered a 5 year warranty on the Sunmaster tank. However, Rinnai Australia are committed to continuous improvement and through innovation have enhanced the efficiency of the Sunmaster Flat Plate System which has sanctioned an extension of the warranty from 5 to 10 years on the Sunmaster tank.

If you are having trouble with your unit we would recommend booking a service call. Please refer to our website with the following link https://www.rinnai.com.au/support-resources/online-service-booking.

That does not really answer my question!
The unit is currently working fine,what I am asking is how long would you expect the unit to last! Ie life expectancy.

Rinnai
Rinnai A.Rinnai

Hi Nick.F,

We cannot provide an exact age for life expectancy, due to a number of factors. Actual life can be impacted by water quality, usage and improper maintenance.

It is recommended that our customers regularly service their products to ensure optimal operation.

If you would like to organise a general service, please refer to our website with the following link:

Sunmaster Evacuated Tube System

Good Morning, we had this unit installed in our new build by our plumber in July last year (2018). Our gas bill is astronimcal all year round, $700 after discount during winter and around $400 during summer when the Hydronic isnt running. Is this normal as the only other gas device we use during summer would be the cooktop two or three nights a week? We have noticed the instantaneous running a lot,even during summer.

Sunmaster Range

our rinnai sunmaster solar hot water system is leaking from the outlet when i turn off the water supply on unit it continues to leak, however when i turn mains off it stops. Why isn't the valve on the hot water unit turning off water ?

3 answers
Richard L
Richard L

Where is the leak? I have 2 valves on the storage unit. One on the supply side and one on the discharge side. If you only turn off the one on the discharge side the unit will still be under pressure and might leak. In any event sounds like you need a plumber.

thanks but don't really want a plumber on a sunday, surely you can turn water off to unit, without having whole house off as well

Sunmaster Range

I have a Sunmaster hot water unit. I think the frost valve at rooftop solar panels is leaking water into the gutter drain pipes. Have organized service call from Rinnai but might be many days before someone is able to come. Meanwhile, is it safe for me to turn off power to the solar pump to stop the leak, relying on gas only to heat the water? Will doing this damage the panels?
Thank you.

2 answers
Richard
Richard

I wouldn’t expect any water leakage from the rooftop unit. You would need confirmation from Rinnai about turning off the power to the circulating pump. I doubt turning off the pump will stop the leak

Rinnai
Rinnai A.Rinnai

Thanks for the question Alex, turning off the pump will not stop the valves from leaking and may expose the unit to damage as you would be turning off the automatic frost protection for the unit. If you have not had the technician attend, please let us know and we will follow up for you.

Thanks
