Migrated to EV solar tubes to heat the geyser


Recommended Posts

I had EV tubes installed yesterday, they finished late so no production from the EV tubes + it rained lekker here late afternoon.

However it 11:45 and I already have 55 degrees in the geyser. I'm feeling good!

In hindsight though, I could have installed this myself, it was actually rather simple, you just have to have the right tools, and a couple for hours, also nothing fancy.

Few pointers if I may.
- If the pump and electronics are off, the water cannot circulate, it then can work towards overheating the water to boiling point.
- Way the systems keep themselves cooled, if you are away for a few days, is to cycle the water back to the panels to cool off.
- If you are on holiday, then the system must be switched to that setting, as per the manufacturers specs.
- If there is no water.
- If there is no power.

CoCT sent out warnings when we had power failures and then water issues.

Good idea to read the manual for the above situations. I should have had my pump on a solar panel, and not Eskom.

I haven't had a "flat line" like this ever...

The 4kW and 7.5kW spike was grid to geyser via Geyserwise timer this morning + the kettle.

I have to find a happy medium on the geyserwise.

The other small 2+kW spikes was the toaster and coffee machine for the "late comers"

Holiday Mode? I'm going to Clarens next weekend so I want to use this option.

I see this option on the GeyserWise MAX though.

I see it "keeps" the geyser at 50 degrees by disabling the element and switching on the pump at 6pm to cycle the hot geyser water through the manifold outside till it drops to 50 degrees or 6am, which ever comes first

Hope you got that one? 

If not, just check your model, how it handles the matter.

Getting a geyser to boil with EV tubes, not THAT difficult. :-) 
... only if things break.

Just a quick tip , that white heat conductive paste be sure to get a bit on the temperature probes particularly on the EV tube heater manifold.

Hi @seant,

Thanks for the tip ... I am also looking at getting an EV tube system fitted.  Why the caution?
