My kitchen is very for from the solar heated geyser.  What options are there for a very small geyser, or any other way of instant hot water?

I am changing to a grid-tied hybrid PV solution, so the kitchen sink must not draw high power for short periods.  4kw is way too much. I would prefer under 2kw, for longer periods. 

So it seems I am looking at a small under counter geyser, with a small element, maybe connected to dumb timer that switches it off overnight?

 

Kwikot has a 10 liter that uses 1500W - at R2450

Lorenzetti  has a instant heater that uses 4400W for R1300 - too much power!

Heattech as a 15 liter that uses 1500W, at R1899

 

Seems like the Heattech is the way to go.  Any experience with these? Plus point: They are a South African manufacturer.

Any other alternatives I should consider?

I put a small 100l solar geyser in for the kitchen. I have even seen 80l geysers as well from time to time.

Another way is to circulate the hot water so that there is always hot water in the pipe.

I've been eyeing this one for a while now but haven't decided yet. No idea about price or any other compatibility issues with things like vented/unvented things that I am not familiar with. The 700kpa limit is perfect for my 600kpa pressure and stores enough water to fill the sink when there is only 'small stuff' to be done without having to pack it in the dishwasher.

For now I run hot water from a mile away, so to speak.

If the intention is to use the hot water for washing up dishes? 15 Liters may not be enough? I find that typically the Domestic uses around 30 Liters to wash dishes? Given that's its coming from the geyser and so a bit of extra water has to drain the pipes before she gets hot water?

What I found was that the dishwasher even though its an older LG2040 (+/-9 years old) uses around 13 Liters per wash, so definitely more water efficient, but its heating element requires around 2kw, which runs for about 10 minutes and then a further 10 minutes near the end of the cycle. Cycle is 1h56m ( for the 70 Deg C cycle).

I would possibly lean towards the Heat Tech, due to the lower power requirement and larger capacity, and would put it on a timer for daytime heating. 

Heat Tech is based in Raslouw, Centurion.

50l geyser for the kitchen with 1 shower on same geyser. Works quite well and sent to heat.

I have bought a small gas geyser for R2200 and mounted it directly back to back with my sink. Shortest possible pipe run to reduce losses. Running from the same gas bottle as my gas stove, works well for me. 

Thanks for all your input. 

I bought the Inventum Q10 for the kitchen a few years ago and it is still working 100%. Piping hot water in seconds.

In those days it was sold by Builders Warehouse.
