Apollon is the top tier of Nobel solar heaters, and the difference is engineered rather than cosmetic: a double-layer glass enamel tank against corrosion, 10 cm of thermal insulation, and thermosiphon operation with no pumps or external controllers. Available at 200 L with a single 2.6 m² collector (4–5 people) and 330 L with two collectors totalling 4 m² (6–8 people).
Who it is for
- Villas and homes with heavy simultaneous demand in the peak hour
- Anyone who wants the fewest parts that can fail — no pump or controller in the path
- Buyers who judge on service life rather than day-one cost
- Roofs that allow the tank to sit above the collector, which thermosiphon requires
When it is not the right choice
If your roof cannot take a tank above the collector — structural load, compound regulations, or the look of the elevation — thermosiphon will not work at all, and a forced-circulation system is the answer. And if your demand is genuinely small, such as a flat with one bathroom and two people, the larger capacity means money spent and higher standing loss for no return. We say that at the survey, before the offer rather than after.
How it works
The rooftop collector heats the water, and the hot water rises to the tank on its own through the density difference — that is thermosiphon. The tank holds the heat behind 10 cm of insulation, so overnight loss is lower and the water is still hot in the morning. Because there is no pump in the path, there is no power draw to run it and no electrical part in the loop to fail.
The benefit you feel
Hot water all day from the sun, and a lower electricity bill. International estimates (US Department of Energy) put the cut at roughly 50–80% of water-heating electricity — the exact figure depends on your usage, which we confirm at the survey. The warranty is 5 years on the tank and 10 years on the collectors, replacement rather than repair: a defective part is removed and a new one fitted.
How it works in winter
On the roof, a collector captures the sun’s heat and a tank keeps the water hot. On sunny days the sun is enough on its own; on cloudy days or high demand, the electric backup runs automatically and tops up — so no cold water in winter.
How many liters for your home?
Nobel solar heaters are available in capacities including 200, 300 and 500 liters, and the right one for your home depends on the number of users and usage. Get an initial size from the calculator in under a minute, and the free inspection confirms it.

NOBEL APOLLON compared with the other Nobel models
NOBEL APOLLON: The only model whose approved specification states an actual capacity, an operating pressure and Solar Keymark certification — the most fully documented of the four.
- NOBEL HYPERIONPairs the APOLLON collector with the AELIOS tank and adds magnesium protection — a combination drawing on both.
- NOBEL AELIOSClosed-loop with an enamelled tank and a surrounding exchanger, plus a service flange, so the tank can be reached without dismantling the system.
- NOBEL SOLFOSIntended for projects, hotels and large facilities, configured to match the project needs. Available capacities: 200 L · 300 L
FAQ
How is Apollon different from other Nobel heaters?
The difference is in how it is built, not how it looks: a double-layer glass enamel tank against corrosion, and 10 cm of thermal insulation, so water stays hot longer after the sun goes down. It runs on natural thermosiphon circulation with no pumps or external controllers, so there are fewer parts that can fail than in any pumped system. The warranty is 5 years on the tank and 10 years on the collectors — replacement, not repair.
What capacities does Apollon come in?
Two: 200 L with a single 2.6 m² collector (4 to 5 people), and 330 L with two collectors totalling 4 m² (6 to 8 people). The right capacity follows the number of users and shower timing rather than the floor area — [get an initial size from the advisor](/en/advisor) and the survey confirms it.
Does Apollon work in winter?
It does, and output drops on cloudy days like any solar heater. That is why it ships with an electric backup that runs automatically when the sun is low, and the 10 cm insulation limits overnight loss — so no cold water. More in [solar heaters in winter](/en/blog/السخان-الشمسي-في-الشتاء).
What is thermosiphon circulation, and is it better?
Thermosiphon means the water moves by itself through the density difference between hot and cold, so no pump and no controller are needed. The advantage is that there is no electrical part to fail and no power draw to run it. The one condition is that the tank sits above the collector on the roof — if that is not possible at your site, a [forced-circulation system](/en/products/forced-circulation-solar-systems) is the answer.
What does "replacement, not repair" mean in the warranty?
It means a collector with a covered defect is removed and a new one fitted, rather than repaired and returned. That is a practical difference: a repair returns the part to something less than new, a replacement returns it to zero. The cover is 5 years on the tank and 10 years on the collectors.
I have a villa with four bathrooms — is Apollon enough?
The 330 L version with two collectors is usually the fit, but the count alone does not settle it: simultaneous shower timing is what actually decides. Four bathrooms used across the day are not the same as four used in the same half hour each morning. Read [flat or villa](/en/blog/سخان-شمسي-لشقة-ولا-فيلا), then book a survey that settles it for your home.
How is the price decided?
We select a smart heating system sized around your home, not a product off the shelf. Price depends on Capacity (how many litres your home actually needs) · Consumption (how much hot water you use per day) · Purchase timing (the season you buy in — costs are not fixed year-round) · Accessories (pump, controller, backup heater and safety valves) · Optional extras (any additions you ask for). After the free assessment, our quote identifies the model, specifications, installation scope and warranty. You get a clear recommendation and know what the cost includes, with installation and support from Aurora.
Already have a solar heater running?
The element, magnesium anode, tank gasket and safety valve are wear parts that run out over time — and if the anode is left too long, corrosion starts eating the tank itself.
