Hi All

I've just recently moved into a new house, and really excited that it already has a solar geyser installed.
Its currently using a Geyserwise Max control unit, and I can see 2 separate sets of 20 solar tubes each on the roof.

I have pretty much figured out (with the help of google) how to use the control unit and set timers etc, however have question which I would really appreciate some assistance with.

I have 2 separate control units. My initial thinking was that I must have 2 separate geysers (1 for each).
However, after taking a long hot shower, I notice the temperature goes down on both units, which would make me think that they are not independent.

Can anyone help me out as to whats going on here please?

Thanks alot

Have you maybe got two geysers? One on the roof feeding a second one (the main one with electrical backup) under the roof. It can be that one controls the feed of the outside one and the second the electrical backup inside.

That could explain the two different temperature readings as shown.

Did the previous owner not leave you with any instructions or describe the system?

They didn't have a clue.
They just manually put the element on using the power button whenever the temperature dropped a bit

There no geysers on the roof. Only the 2 sets of tubes

do you have possibly 2 geysers one feeding the other?
what about on the DB board are there 2 geyser switches?

I would like to say what kind of an idiot lives in a house but has no idea how to use what he has, but sounds like the previous owners of my place.
did they switch on both back ups?

since you only see the tubes, you will probably need to go into the roof to see what is there.
 
Agreed, I think the 1 feeds the other.
That's a great idea, will check the db board when I'm back there later in the week.


Yes, they would just put them both on for about an hour they told me.

If this is the set up, what would be the best way to set up the timers and temperature etc? Should both be the same?

Thanks for all the help, much appreciated!
 
That is difficult to answer without knowing the setup.
The maximum temperature on the storage geyser would be 65 degrees I would think, and the other IF it is just a controller for the solar geyser is for protection of the solar system.

If I were you, I would find out what system it is and who installed it or get the supplier to give you a quick training course on how best to use the system.

had to say without knowing the setup, like are both solar or just one, sizes etc.
also how many bathrooms and how many people
 
That label on the geyser wise unit seems to refer to Eskom --- subsidised geysers which would have been installed by a recognised and Eskom accredited installer.
 
Only way to find out what is going on is to follow the cables. Nevertheless I'm going to take a punt here and hazard a guess as to what is going on, although I could of course be horribly wrong.

There are two geysers, one connected to solar and one not. The solar geyser feeds the other geyser, from which the house draws it's water. If this is indeed the case I would set the solar geyser to never turn the element on, and the second to 50 degrees 1 hour before you typically need hot water.

I think we all making a similar assumption
the only thing is OP mentioned 2 sets of Tubes on the roof, so might actually be 2 solar geysers
if so i would say only turn the element on the 2nd geyser ( the one that feeds the house).
It would really help with more pics of the tubes on roof and if possible geysers in the roof

@Mark051 ?

Other way to test would be to leave the power off to they geysers (assuming there is some sort of PV / battery backup) and see which of the geysers heat up. That should indicate if they're both on the tubes or not.

or press the up and down buttons together :) it should show the temp of the collector - if one is a 0 i think that means no collector connected but if both have temps that means both have their own collector
 
I think only one geyser is connected to electricity as the one controller has an anode warning light and the other not.
I might be wrong though.
 
Thanks everyone, really appreciate the assistance.
I'll try answer some of the questions above.

Both units show increasing temperature throughout the day( when not using any electricity) , so I would assume there are 2 solar geysers.

Also, when pressing then up and down arrow together, I do see the temperature in the collector.

It's a 3 bedroom house with 3 full bathrooms.

I'm not living in the house yet, so will try send more photos when I'm there again.

I would guess the set up is as isie mentions. Ie 2 solar geysers with the 1 feeding the other.
Would it always be the same geyser that's the 'feeder' and the other the "receiver', or could 1 geyser be for 1 side of the house and the other geyser for the other side. Then whichever geyser is being used would be fed by the other?

Apologies for all the questions but really have no clue.
 
It would make sense for us to all wait until you have a better idea of what the install actually looks like.
@ systems, 3 bathrooms plus kitchen suggests that one geyser feeds two bathrooms, and the other the kitchen and the 1 bathroom

Yep sounds like both are Solar

Normally you would always have 1 feeder one receive - unless they didn't connect it correctly and one geyser emptying backward into the other or the joined the outlet pipes- I can think of 100 different scenarios for you so lets wait till you have more information don't want to confuse you before you moce in:)

never apologise for asking questions,
Rather ask questions and be an idiot for a short time then remain silent and be an Idiot for the rest of your life.

Are you renting or did you buy?
