200 Litre ETC Solar Water Heater

Capacity: It can provide ~200 litres of hot water per day under optimal solar/heating conditions. Enough for around 4‑6 people depending on usage.

ETC (Evacuated Tube Collector) type: Uses vacuum glass tubes to collect heat; these tubes have two layers of glass with a vacuum in between, which reduces heat loss. They work better in cold climates or when direct sunlight is less strong.

Non‑pressurized / Thermosyphon type (often in basic ETC): Water circulates naturally by convection (hot water rises), no pump is needed; works well where installation allows the storage tank to be part of the raised collector set‑up.
