Loss of Hot Water Pressure returned
Hi I just thought that I would add this to the forum.
We have a Rinnai Sunmaster flat panel solar system and over the last approx. 2 years when we turned on the hot water anywhere in the house there was very low pressure We had plumbers come out they did what they do and went away sometimes the water pressure would be better but if it was it would not last.
Any way just last week I found Celsius Heating & Cooling here in Ballarat I believe they are service people for Rinnai anyway they had a contractor by the name of Phil he came out listened...
Questions & Answers
Hi, I have noticed that the pump isn't running anymore, is it dependant on outside temp or should it continuously be circulating water between tank and solar collector. Outside temp is about 12 deg C.
The pump will run more in times of more solar gain but even in winter months there is a setting called low temperature mode which will activate the pump to protect the system against frost damage,
We would recommend speaking with the technical help desk on 1300 555 545 option 3 to check the pump operation and book a service call if required.
Hi Rinnai support,
I have just checked with my neighbour who has same unit and his circulating pump isn't running either, we'll both wait to see if when we get a bit of sunshine to heat the water in the solar panels if the circ pump switches on , if not we will both call the help desk for a service call.
My question to Rinnai is, given the laundry list of similar complaints, has anything been changed in the units over the years to give me any confidence in outlaying $5k that the unit will be fit for purpose?
there have been many changes and upgrades to our solar range over the years. Our technical team can discuss any specific areas that might be of interest to you as well as giving you some advice to ensure the right system is chosen for your needs,

I have a 250ltr Sunmaster. House & HWS only 2 ½ years old. Have just realised that my household 240v power usage soared by factor of 3 to 4 at end last year. AGL have said meter OK. I am in process of seeking cause & now focused on HWS as little else in household uses power. Established that HWS solar pump is running 24/7 - no idea how many months as very quiet & only heard with ear to pump cabinet. 240v booster continuously "on" from beginning so not cause for change in power use unless change in something like pump not turning off can increase use of 240v heating. Needing guidance. No knowledgeable local plumbers available at present.
Hi John S,
We have a technical help desk who may be able to provide assistance but will need more information to help. They can be reached on 1300 555 545 option 3.
Already been there. They suggested plumber [& not much else] but no good ones available at present. What is actual consequence if pump running 24/7. Does it make 240v element work more by constantly feeding water past whatever sensor activates? Does it reduce solar heating performance - eg water not as hot [when turned 240v off for 3 days. As part of current seeking answers, the water dropped to "warm" despite sunny [winter] days. Rgds John
Hi John S,
Potentially having the pump running constantly could affect the water temperature in the tank, cooling down water that has already been heated however without further information it is difficult to be specific with the issue.
if you are unable to find a local plumber with the experience to check the system, you can book a Rinnai technician through our online booking and they can check over the system to see if there are issues that need to be resolved.
