Hi I have a rinnai Sun master s20 hot water tank.
Is it normal for the hot water pressure to be half as much as the cold water? As you go from cold to really hot the pressure is substantially less

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

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 ?

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.

Hot water is available in kitchen, but I other areas, when turning on the tab for hot water, the water stops but if it is cold water, the water flows fine. What is the problem?

We have a 315lt evacuated gas boosted unit. Every time you turn the tap on the gas boost starts up and keeps running. I could understand this first thing in the morning after a cold night but today was 21° and sunny for 95% of the day although with a cool wind. Our panels face north.
Why is it doing this we have just had a sensor at the tubes replaced. The system is only 6 months old.

i need to replace my 315L Sunmaster tank and have found a replacement but the solar return and hot water outlet ports are on the opposite side to my original tank.
Is there a difference between the hot water outlet and solar return ports?
Can i connect the hot water outlet to the solar return port and the solar return to the hot water outlet?

They installed a Rinnai sunmaster system 6 weeks ago.every week a technician has to come and fix it as i have no hot water. They fix a valve or whatever and it works for 3 or 4 days and then goes cold .this has gone on for 6 weeks.
I am disgusted with this installation. I feel i have had a lemon installed.

Is it ok to leave power off to hot unit when house is empty can this damage panels on roof

We are a family of 5 our unit was just installed with only 1 solar panel on roof for our sunmaster. Shouldn’t we have more than that? Is it possible to add another?

We have a a Sunmaster 20 that has been problematic in two ways. the first is that since owing our property "every" year the side valve blows out due to cold weather - at a repair cost of $300 each time I was told by Rinnai Tech Service that these units are very robust and should not be having this issue, but here we are with these problems.
The second issue is that the unit in its 5th year of service is now actually blowing the main circuit breaker of the property causing total power failure, once again I was assured that the unit is not at fault but more likely the property wiring - the property is 5 years old, when the S20 is disconnected there is not issue and has been checked by a qualified electrician. Is this S20 actually "fit for purpose" in Australia given its Japanese heritage? The "head in the sand" phenomenon seems to be becoming more and more prolific - and the reply of "we never have these problems" is becoming too common.

Just installed a evac tube sun master electric boost about a month ago. Today we have had very loud banging noises in the roof. And I also heard the base unit gurgle a few times. The banging noise tends to happen when I’ve been using the hot water. It has been a warm day (prob about 28) but this is nothing compared with our summer temps to come(high 30’s and low 40s) what could the problem be?

I have a rinnai solar 20 on a sunmaster but the temperature is not high enough for my liking. Can I turn it up?

We move in to new home last week with this Rinnai Sunmaster gas boosted solar hot water unit 175 litre storage tank Infinity 20 continuous flow hot water system what they call it. We never have full hot water shaver since last week. It start ok with hot water and after couple of seconds it run of of hot water. It seems to me unit only running on solar .. maybe for some reason gas booster is not kicking in i maybe wrong and i don't know how to check this and need your advice.
So far check and confirm below
1. we have run gas on to house
2. power supply to unit is connected and active
appreciate your help/advice on this regards

Got problems with my system it's been in for 7 years it's leaking like a rust substance from the inlet and even from round the top cover and even out the the electrical box I'm sure it's only a matter of time before it explodes .and noticed theres a white rust build up in the panels on the tubes.what should I do and how do I get someone to evaluate what is happening .do you have a company representative that can inspect it.?
