Geyser conversion/replacement

[Cactus]

Morning mybb.

I'd like to convert/replace my geyser with something more energy-efficient around the end of this year. From a quick Google and speaking so various people, I see 4 possibilities.

1. Convert the existing geyser to a solar geyser
2. Replace the existing geyser with a solar geyser
3. Replace with a gas geyser
4. Add a heat pump (not exactly sure how this one works)

My budget would probably be around 20-25k for this. I need to cater for 3 people at most (over the holiday, else just me) and my current geyser size is 150L. I don't plan on going full solar with the rest of the house, so I don't need to cater for this to work with solar at all.

From what I heard speaking to people, the solar geyser with a 12V motor approach isn't that effective and a bit noisy.

Has anyone done this before and what did you end up going with? What was your monthly savings for electricity?

You can hire professionals to retrofit your 150L for around R15k best decision ever our geyser was on 22 hours in July for the period it needed to switch on to hit 55 deg. Goes on twice a day

Go solar evac tubes

I would say go convert your solar - plus with the size of your geyser it will be way under your budget
As for the 12v motor approach - i saw WTF are they talking about
I assume they referring to the pump (can be 12v solar or 220v grid) - both are so small you can't hear anything and contrary to what they say it is very effective - personally speaking to people who have solar and see no benefit I note they are not using it correctly.

as for monthly savings - in summer looking at a 40-60% drop in consumption - winter significantly less but still get some good days /
the above percentages is also based on how you use the geyser.
remember it takes significantly longer to heat water with the sun compared to using an electric elements - also most good conversions will still include and electric element and a controller so you never without hot water, in theory you let the water slowly warm up during the day and you then take a shower in the evening or leave it to stay warm in the tank and if needed get a little electric boost before your morning shower. of course the more people using it the more you might need the electric back up coming in. but you will still see a saving.

I went the gas route as it also allowed me to introduce gas into the kitchen later — bottles were in place. This also allows me to prepare food when there is load shedding.

Induction geyser, anybody have experience on these? Savings %'s ??

Solar etc tubes with electric/gas backup. To maximise savings when it just 1 or 2 at hoe shower in the evening and set the electric element to only come on in the late afternoon and under 55C

Not under 55C. Legionnaires Disease is real, and deadly.

There is also this option, which eliminates additional plumbing of EV tubes and pump. I've had a few solar dealers recommend this over collectors.

I need 406 refrigeration gas to top up my heat pump installation. Any idea of small supplier in Cape Town area or some one who can top up?

Final option?
