Raiden2912 Posted April 28, 2023 Share Posted April 28, 2023 (edited) Hi All, im looking at a few options for my Geyser element and came across the geyserwise which is quite popular and which a lot of people recommend, however I also through my research have spotted standard 2kw elements at a fraction of the cost, what is the benefit of the geyserwise element? Does it warrant the cost ? Roughly R2k Vs something like this? is it possible to use the Geyserwise element without the geyser connected to a solar panel? I don’t have essential Vs non essential loads…. https://www.google.com/shopping/product/12912288135110294072?q=geyserwise+element&client=safari&biw=430&bih=740&tbs=vw:l&prmd=sivn&prds=eto:14359060103193927311_0,cdl:1,prmr:1,cs:1 Edited April 28, 2023 by Raiden2912 Quote Link to comment Share on other sites More sharing options...
GreenFields Posted April 28, 2023 Share Posted April 28, 2023 Some opinions already in other threads. My guess is, you'll get years of good service either way. See here and here BritishRacingGreen, Raiden2912 and hoohloc 1 2 Quote Link to comment Share on other sites More sharing options...

You can use both at the same time or one at a time and yes you can use the element without the geyser being directly connected to the solar panels. In my set up, the AC supply to the element is controlled by CBI Astute smart controller, connected to the DB supply. The DC supply is controlled by SONOFF to switch ON/OFF a contactor that is connected to the battery bank, 48v Edited April 29, 2023 by hoohloc Raiden2912 and zsde 1 1 Quote Link to comment Share on other sites More sharing options...

Raiden2912 Posted May 3, 2023 Author Share Posted May 3, 2023 Question: The Geyserwise timer will be setup at my DB board? Or closer to the geyser? Quote Link to comment Share on other sites More sharing options...

You want the controller close to where you want to use the hot water, i.e. just outside bathroom. Raiden2912 1 Quote Link to comment Share on other sites More sharing options...

Modina Posted May 3, 2023 Share Posted May 3, 2023 Huh????? You have an awfully large thermostat. It would do nicely as a self-defence weapon. That clobbering tool is not a thermostat but a PTC element. The new thermostat is a very small device with thin wires that gets inserted into the hollow tube in which the old thermostat was mounted. If you want to fit that PTC element you would need to drain your geyser (at least partially). Raiden2912 1 Quote Link to comment Share on other sites More sharing options...

Outside will save you some cupboards when the geyser bursts. And I am confident that you increase the hot water capacity when the geyser is standing upright vs on its side.

Modina Posted May 3, 2023 Share Posted May 3, 2023 The control box has a power supply to power up your keypad. It also reads the new thermostat and houses a relay to switch the element on or off. Raiden2912 1 Quote Link to comment Share on other sites More sharing options...

I changed to a 1.5Kw Geyserwise, dual supply. it uses 800w when being powered from DC and 1500w when using DC or you can use both supplies simultaneously and get just over 2kw if you want to quickly heat up the water. I only do that when I have excess solar and my batteries are full. I switch the DC supply on at midnight, the water is nice and warm in the morning and my gas water heater doesn't need to boost the temperature at all. Now I'm only using the gas for cooking, too much information hey! I get so excited talking about my system Raiden2912 and McGuywer 1 1 Quote Link to comment Share on other sites More sharing options...

I want to reach that stage myself , I am considering replacing the 3kW element with a 1.5 sometime in the future. Mostly to play nice with other loads during PV hours. At 3kw with a 4.6kw PV array , you can basically have the 3kW geyser on and nothing else , and only for limited periods. hoohloc and Raiden2912 2 Quote Link to comment Share on other sites More sharing options...
