The Cadac Ecoflow range is our most affordable installed gas hot water: the Cadac 12L Ecoflow from R11,000 supplied and installed — suitable for a granny flat — and the Cadac 16L Ecoflow from R12,200. Both are built for flats, granny flats and smaller homes rather than whole-house demand, and their low-flow start lights where softer water pressure leaves others hesitating. Cylinders, cage, cover and a flue where required are extras.
Flats, granny flats, rental units, smaller homes and any setup running lower water pressure. If your hot water needs are simple — one bathroom, one person showering at a time — this unit does the job without you paying for capacity you will never use.
We will not sell you a Cadac as a whole-house premium solution. That is not what it is, and pretending otherwise just gets us both a call-out in July.
The 16L Ecoflow unit is R5,700 and installation starts from R6,500, so it comes in from R12,200 supplied and installed. The 12L Ecoflow unit is R4,500, from R11,000 supplied and installed. Cylinders, a cage, a cover and a flue where required are extras on both.
Cylinders, a lockable gas cage where the cylinder stands somewhere public — common in complexes and rentals — the weather cover, a flue where one is required, and the distance from the cylinder to the geyser wall. None of those are included in the from-price. No electrical point is needed, which keeps the total down.
Yes — and this is the genuine reason to pick it. The Cadac has a low-flow start, meaning it fires at a lower flow rate than most units need. In a flat on an upper floor, or a house on older pipework where the pressure is soft, that difference is what stands between a hot shower and a geyser that never lights.
It is also the main reason we would choose a Cadac over a Dewhot in some homes. If the pressure test on the assessment comes back low, the more expensive unit is not automatically the better one — the one that actually ignites at your flow rate is. Our technicians measure rather than guess. If low pressure is your ongoing complaint, read up on common gas geyser problems first.
Both are 16L, both run on batteries, and both need a weather cover. The Cadac is cheaper and handles low pressure better; the Dewhot is a step up in temperature control for a standard family home. Pick by house, not by price alone.
R5,700 unit · from R12,200 installed
Lowest installed price, low-flow start, and a practical fit for flats, granny flats and rentals. Comfortable running one hot outlet at a time.
R4,500 unit · from R11,000 installed
The smaller Ecoflow — suitable for a granny flat. Same battery ignition and low-flow start, sized for one shower or a kitchen at a time.
R8,500 unit · from R15,000 installed
Constant Temperature control, steadier under mixer taps, and the better choice for a standard three-bedroom family home with a bath and a shower.
Compare the Dewhot 16L →Honestly? Probably not, if you mean a larger family home. A Cadac will run a flat, a granny flat or a smaller dwelling comfortably, and it will run a proper shower — but it is not built to keep two bathrooms and a kitchen going at once on a cold morning.
If that is your house, step up: the Dewhot 16L for a standard family home, the Rinnai 20L or Paloma 20L for whole-house demand. Buying the cheapest unit for a house that needs more is the one mistake that costs money twice.
The unit being affordable changes nothing about the gas. LPG installations must be done by a registered installer and certified on completion — that is the law, it is what your insurer expects, and it is what keeps the household safe.
Correct line sizing, proper leak testing, safe cylinder placement and adequate ventilation. Gas done wrong is dangerous in a way a leaking tap never is.
An uncertified installation can void your insurance and will hold up a property sale. See gas compliance and safety inspections.
A budget unit installed well outperforms a premium unit installed badly. Commissioning and testing at the taps is what turns a box on a wall into reliable hot water.

Small-space installations where cylinder placement, low pressure and complex rules all matter. The Cadac 16L Ecoflow is usually the right unit for the job.

Compare the modelsYes. Cadac is a long-established South African gas brand and the 16L Eco is a practical, well-priced unit that does exactly what it claims. It is not a premium whole-house geyser and it is not sold as one. In a flat, a granny flat or a smaller home it is a sensible, dependable choice — parts are available, we know the unit well, and we fit them regularly across George.
