Do I actually need a chiller?
In a Cape or Highveld winter, for a 12–15 °C plunge, genuinely not. For 8 °C year round, or anywhere on the KZN coast, yes. We will tell you which before selling you a machine.
Does Johannesburg's altitude matter?
Yes. At about 1,750 m the air is thinner and the heater is sized up, the same correction we use in the East African highlands. It is shown in the quote.
Is load shedding a problem for this equipment?
Not any more — the country has passed 475 days without it. We use the backup hardware households already own for efficiency instead: the chiller on a backed circuit, the heater scheduled into your solar window.
Do you build outside Cape Town?
Yes — Johannesburg, Pretoria, KZN, the Garden Route and bushveld lodges. Trips are scheduled in blocks so several jobs share the travel in the same week.
How often does it need servicing?
Six months inland, three months at the coast and in the bushveld. Coastal visits include a corrosion inspection; bushveld visits include a dust inspection.
What about hail on the Highveld?
Heavier roof gauge and impact-rated glass where it faces up. We have replaced other people's polycarbonate after a single storm.
Can a plunge go on a deck?
Only with the structure checked. A 900-litre tub is nearly a tonne, and on a cantilevered Clifton deck that needs an engineer's opinion, not an opinion of ours.
What is the payment schedule?
40% to start the drawing and order materials, 40% when panels leave the workshop, 20% on commissioning.
