Dewhot 16L Gas Geyser Installation in George — Reliable Mid-Range Hot Water

The Dewhot 16L Constant Temperature sits in the sweet spot between budget and premium. It runs on batteries so load shedding doesn't touch it, it works with mixer taps, and it keeps standard family homes across George in steady hot water. Around R15,000 installed on a single cylinder.

Who Is the Dewhot 16L Best For?

Standard family homes, and homeowners replacing a burst electric geyser who want something better than entry-level without paying premium money. It is the unit we fit most often in ordinary three-bedroom George houses, and it does that job properly.

A good fit if

  • You have a normal family home with one or two bathrooms.
  • Your electric geyser has burst and you are switching to gas.
  • You want hot showers through load shedding without an inverter.
  • You have mixer showers and want steady temperature at a sensible price.

Be honest about the limits

  • It cannot take preheated water, so it is not a solar-inline unit.
  • Two long showers at once in winter will stretch a 16L — that is a 20L job.
  • It needs a weather cover outdoors; that is part of the install, not an upsell.
  • Batteries need replacing roughly every 12 to 18 months.

How Much Does a Dewhot 16L Cost Installed?

The unit is around R8,500 and installation starts from R6,500, so the Dewhot 16L Constant Temperature comes in from R15,000 supplied and installed. Cylinders, a cage and a weather cover are extras on top of that, quoted with the job.

What's included

  • Supply of the Dewhot 16L Constant Temperature unit with warranty.
  • Gas line correctly sized, secured and pressure-tested from cylinder to geyser.
  • Plumbing connection, isolation valves and tie-in to the existing hot and cold lines.
  • Weather protection for the unit — essential on any outdoor installation here.
  • Commissioning, testing at the taps and your Gas Certificate of Compliance.

What moves the price

How far the gas line has to run is the big one. After that it is the extras: cylinders, a lockable cage where the cylinder stands, and the weather cover the Dewhot needs. None of those are included in the from-price.

No electrical point is needed, which is one of the quiet savings on a Dewhot install compared to a Paloma or Rinnai. The full breakdown of what a GasCraft install covers is on the installations hub.

Does the Dewhot Need Electricity?

No. It runs on torch batteries, so there is no plug point to install and no reason to lose hot water when the grid goes down. Batteries last roughly 12 to 18 months depending on how many showers the household gets through.

That independence is the main reason people choose it over a Rinnai. Keep a spare set of batteries in the kitchen drawer — when a Dewhot suddenly stops clicking, flat batteries are the first thing to check and the fix takes two minutes. If fresh batteries don't bring it back, phone 071 551 2108 and we will diagnose the fault properly.

Will the Dewhot Be Hot Enough in Winter?

For most standard George homes, yes. Winter performance on any gas geyser depends on three things: how cold the incoming water is, how fast it is flowing through the unit, and how the plumbing is laid out. A 16L unit heating cold July water has to work harder, and the Constant Temperature control is what keeps the shower steady while it does.

Where it gets stretched is heavy simultaneous demand — a bath filling while someone showers, in the middle of winter. If that is your household's normal morning, we would rather step you up to a Rinnai 20L or a Paloma 20L than sell you a unit that will frustrate you every July. we make that call on the assessment, not over the phone.

Dewhot vs Cadac — Which Mid-Range Option?

The Dewhot is a step up from the Cadac, and the Cadac is the better unit in the right house. It is not a quality ladder so much as two different jobs — family home versus flat, normal pressure versus soft pressure.

R8,500 unit · from R15,000 installed

Constant temperature control, better behaved with mixer taps in a standard home, and comfortable serving a bath and a shower in sequence. The right choice for a normal family house in George.

Cadac 16L Ecoflow

R5,700 unit · from R12,200 installed

Cheaper, and its low-flow start means it lights where softer pressure would leave other units hesitating. Built for flats, granny flats, rentals and smaller dwellings rather than whole-house demand.

Why Does the Dewhot Need a Weather Cover?

Because rain and coastal moisture kill the board and the wiring loom. Battery units are more exposed than mains units in that respect, and George weather — driving rain off the mountain, salt air in Herolds Bay and Glentana — is unforgiving of an uncovered geyser.

A proper weather box is a permanent part of an outdoor Dewhot installation, not an optional accessory we tack onto the quote. It keeps water off the electronics, shields the burner from wind that would otherwise blow it out mid-shower, and protects the battery housing from the damp that corrodes contacts. Units we are called out to with rain damage almost always turn out to have been installed uncovered by someone else.

Dewhot 16L FAQs

No. The Dewhot 16L Constant Temperature is not designed to run inline on preheated water, so if you have a solar system feeding warm water into the geyser, this is the wrong unit. Fitting one that way leads to erratic firing and disappointed customers. For solar-inline work you want a Paloma 20L or a Rinnai 20L, set up properly for a warm feed. we will spot this on the assessment before anything is ordered.
