I've had the Geyserwise MAX with water filled solar collector tubes for more than 10 years now. Apart from a service once every few years, it just runs and produces plenty of free hot water. It is really an excellent brand!!
My only issue was changing the settings is awkward and having to look in the cupboard to see what the temperature was. But I solved that recently by adding the Geyserwala Connect smart WiFi upgrade which gives me a full featured app so I can see and control my geyser from anywhere.
I highly recommend the WiFi upgrade from Thingwala it completes the trusted Geyserwise brand perfectly.

Yes, no problems with it.

@zabdab Yes, I still have the Geyserwala and am very happy with it.  I have integrated it into Home Assistant and Apple iOS for control and automation also.  Great Product.

Hi Zabdab, I purchased the geyserwala about two or 3 months ago and have been really happy with the product. No more guesswork or walking up and down to go check temperatures.
The graphs on the app could be a bit better it is very basic, but the ability to boost the temperature helps when you need the extra temperature to keep the wife happy. It is very easy to create and delete timers on the app.
It was very easy to install and get the geyserwalla up and running.
