Thermal decks for camps, from the Serengeti to the crater

Sized on the peak, not the average

Demand at a camp is not spread across the day. It is concentrated into the window between the drive returning and dinner, and again briefly at dawn. Everything is sized on that.

In practice that means a heater chosen for a fast heat-up rather than an economical hold — a cabin that takes an hour to get hot is useless when guests are back at five and eating at seven — and more plunge positions than the guest count suggests.

Power and water are both budgets

Most camps run solar with battery storage and a generator behind it. The heater and the chiller are the two largest loads and must never start together, so we sequence them in the controls, schedule the heater into the solar window where there is one, and work from the camp's actual figures rather than assumptions.

Water is the harder constraint. Camps truck or borehole their supply, so the plunge is sized to the water budget rather than the brief, and filtration with ozone extends water life to a month or more. An insulated lid is an operating saving measured in litres and kilowatt-hours.

Dust in the lowlands, cold at altitude

Serengeti, the Mara, the southern parks and the bushveld: dry-season dust blankets a condenser in weeks. Washable pre-filters, sealed plant housing, units sited away from the approach track and a three-month interval that is actually kept.

Ngorongoro, Moshi and the Atlas: altitude and genuinely cold nights. Heater corrected upward, floors insulated as heavily as walls, pipework kept inside the insulated envelope, and a plunge that often needs no machine at all. A camp that has both gets both specifications quoted explicitly rather than an average.

Fly-in, park rules and shutdowns

Where a camp is reached by light aircraft, the aircraft's door and weight limits set the component sizes — from the first drawing, not at the airstrip.

Inside national parks and conservation areas, works, noise, materials and above all grey water are regulated. We design the grey-water route properly, specify biodegradable chemistry and ozone rather than heavy chlorine, and prepare the submission.

And where a camp closes for part of the year, we build in a written shutdown and start-up routine and walk the team through both. It takes an afternoon and it is the difference between opening the season with a working spa and opening it with a repair bill.

In short

• Heater and chiller sequenced so they never start together on a generator
• Plunge sized to the water budget; the lid is an operating saving
• Dust package in the lowlands, altitude correction and insulated floors at height
• Grey-water route, park submission and a written seasonal shutdown routine
