Had my Gas geyser installed today
Went with the 20L Fan Forced Outdoor Room Sealed unit from Dewhot. SKU OD20DH 
Unit cost : R 13000
Gas piping and installation: R3100 (with COC)
Plumbing materials and installation : R2200
2 x 19L Gas bottles R1900 including the deposit : R1900 
The unit is using 220v AC - So the solar backup system is going to take care of power to the unit

Fun Fact:
I connected a AC power meter to my old geyser circuit the last few days just to verify the power needed to keep the 200L geyser with warm water
I left it over a period of 3 days to get some level of consistency of power over a 24h period. considering the load shedding schedules etc.
This was important for me to know what I ACTUALY use from Eskom to power my geyser before they disconnect it.
Consumption Electricity : 
Sun: 19.9Kw pd 
Mon: 20.1kw pd 
Tue: 18.7kw pd
 
Think about the numbers +/- 20Kw per day - 600Kw less to pay towards electricity bill
My unit rate is around R2.00 per KW - this is R14,400 per year. 
Sure, I will spend money on Gas, but less dependency on a single point of failure.   
I can highly recommend my installer - ping me if you need details

Will post some pictures in the next week.
