With all the loadshedding at unpredictable/odd hours, I'm considering a gas geyser solution in one of the bathrooms. I'd like some advice from members who already have a gas geyser system installed.

Certificate Of Compliance is needed by an accredited installer.
File this with your insurer and have it in writing that they are happy with it in case of the unexpected etc.

Run the solar through the gas geyser for the best results.
If the water is under the set temp it'll heat it.
Go for a decent constant flow 20L geyser.

Is the unit installed outside?
 
Extremely convenient and I would recommend it any day.
Not the most economical appliance.

I second this.

I installed my gay geyser last year. Unit sits outside. Uses 48kg bottle every 6 months. But that’s very dependent on number of people in the house. We also have a gas stove running off those bottles.

100% recommend this. If you have a solar geyser as you say. Even better. As mentioned have if feed to gas geyser only when temp is not hot enough. That way I’m good days your gas usage will be lower.

End of last year we moved into a house and it had a gas geyser installed. 48kg bottle, gas fireplace and oven/stove as well. I was a bit skeptical, but the first bottle lasted us (3 people) roughly 5 months. Pretty impressed and very convenient. Just not always happy with the amount of water "wasted" before it gets hot, but if you get creative you can use it for something else.

Talking of waste; if we think about a conventional geyser for a moment. You heat up 150L (or 200L) of water to 60c or higher. Then you take a shower and use like 12L of water and have to now reheat your 200L geyser to get back to 60c

A gas geyser is very efficient that it heats up only what you use.

For sure. I think it was just a case of us always trying to mindful of not wasting water and then having to get used to how this geyser worked.

Thanks for the info but I think I will be better off with the gas version.

You can put in a recirculation line back to the geyser like they do in hotels, basically a third tap that you open and close before opening the hot water.

For that you need a relative expensive gas geyser. These cheaper ones don't have that kind of Intel built in, it just runs water through an x length of tubing known for getting the water nice and comfortable if you have flow rate of x.

Yes you get those gas geyser, but a "cheap" one ain't it.

I agree with the 20l capacity as mentioned earlier. Mine also works better where I have separate hot and cold taps rather than a mixer unit.

Nah you don’t need an expensive unit. Put in a valve on the outlet of the conventional geyser that will either divert water to the gas geyser if it’s too cold or divert to the taps instead if above a certain temp.

I have one of these installed on mine (which I use the solar to heat on sunny days)

Solar to Gas Valve - Dewhot Gas Geysers and Hobs

The Solar to Gas Valve is designed to be used in conjunction with solar water heating systems. If the water from the solar system is not hot enough the valve diverts the water to the gas geyser to increase the temperature. Download the Solar to Gas brochure

The amount of water saved would be minimal to the cost of the line?

I know on a conventional geyser you can do this so that you have hot water as soon as the tap is opened. But the concept doesn’t work on tankless systems.

Rianni are the best and have fantastic functions

True to that, but essentially you want a happy medium where you just want to add the least amount of cold water to the mix for everyone

But yes, I do have a mixer tap on my shower and should someone only want lukewarm water (just breaking the chill so to speak for a hot summer day of likewise they'd be having a problem as the geyser kicks out on low flow. Can go up to about 1/3 down from max (which is still too hot for some on a summer day). Me, I like it nice and toasty always
