Gas geyser - capacity & using along with a standard geyser

soulie said:
that is exactly what i try tell people with electric installs ,that judge listening to you and that long tale isnt stupid .edit ,as far as i can remember that gas thing happened in a cottage

Could have been, it happened here on the Garden Route not too far from where I live

Damn, did not know this. It appears I'm over the limit with 4x19KG and 3x9KG cylinders

Only really an issue if you have a gas related accident and insurance says Nope.jpg because Noncompliant :whistling:
 
Harmonic said:
Absolutely. Had a gas installer here a few weeks ago and he told me a horror story of a couple who died because a gas geyser was installed in the bathroom without a flue. Apparently the guy who installed that is being charged with manslaughter

Was that the one on Carte Blanche?

It's not like you can trickle-heat your geyser in the same way you could trickle-charge a battery if your solar is producing only a little bit.

In theory all you need to do is be able to vary the voltage. A 3 kW heater at 230 V nominal is just a 13 ohm resistor. Run it at 100 V and it will put out 1 kW, or 80 V for 500 W.

Whether doing that is cheaper than a second element though...

I was chatting about these in some other thread - but I can't find it ... so thought I'd just open a new thread .

My neighbour is getting a 20l gas geyser when he gets back from traveling and we started chatting about the specs. What I don't get is why - if it heats on demand as he says - is there any capacity at all ? Surely it wouldn't need any capacity as it wouldn't need to store anything ?

The second fthing is how does it work next to an existing traditional geyser ? Are they run seperately and installed the near the tap ? Or it installed before a traditinoal geyser ?

Read through all this thread to find out what a stadard geyser is or what a traditinoal geyser is

I'm not aware of a simple, standards-compliant way to do this though.

But I w onder how many don't know what I'm talking about when I speak about them?

Which is why having a solar first-stage was discussed, I think.
But again, the costs all add up so it's going to be a case of whatever you've got budget for.

If going solar for the house using existing geyser as a feeder for gas geyser may be a nice middle ground

Most solar installations have idle panel time dump load of a geyser would help optimise production and supply better starting point for gas geyser

Maybe PWM dimmer that can handle 3kw, sure with enough googling a person may find one eventually

edit the only problem with dimmer is most have this funny adjusting system not a dial 20-100% that you can decide ok give me 30%

What about a solar geyser … why don’t they run off standard PV panels ?

Different mechanics,less efficient to convert light to electricity to heat when you can just take the heat directly - or do both with hybrid panels

Didn't even account for the 1x5KG and 1x3KG cadac cylinders for a total of 111KG :ROFL:

Apparently that 100KG limit is for outdoors only so I'm not actually over. Limit for indoors is apparently 19KG

no ,limit is per property ,the 19 kg is the max size of gas cylinder that can be stored indoors .there is also a clause as to how many cylinders may be stored on a property ,it all depends on how far that neighbours wall is and how fast you can carry them .

So this is what I read for outside:

A total of 100kg's is allowed outside per a ERF number. If a property requires more than the allowed 100kg's, The property will require fire department approval with drawings showing the propossed location and setup. In some cases, Your local bylaws may differ to the allowed maximum allowance.

And this inside:

Internal Installations for houses (including cluster housing and group housing (not exceeding two storeys), a total maximum of 19 kg is allowed to be installed inside.

yes that 19 kg is included per property,empty or full ,you may only install a cylinder of 19 kg or less inside .you also may not have more than (5 cylinders per property …as far as i can remember)i think the wording is a bit funky ,like i said earlier you can ask for relaxation ,

Sheesh. Wtf do they expect people with larger homes to do? It's pretty easy to hit the limit
 
there are many clauses ,also for the max size of cylinders per flat i think is 9 kg .speak to the firechief or his dept .
