Kwikot 200L Evacuated Tube Solar Geyser

What Is the Kwikot 200L Evacuated Tube Solar Geyser?

The Kwikot 200L Evacuated Tube Solar Geyser combines Kwikot’s high-capacity 200L storage tank with a 30-tube evacuated tube collector panel. It is designed for households of 3 to 5 people who require reliable hot water through South African winters, when cold mornings and high altitudes significantly reduce the output of flat panel solar systems.

System specifications: Tank capacity: 200 litres | Collector type: 30-tube evacuated tube panel | System type: Thermosiphon (gravity-fed, no pump) | Backup element: 3kW | Recommended household size: 3 to 5 people.

Why Evacuated Tube at 200L?

The 200L evacuated tube model is the preferred choice for Gauteng and Highveld households where winter mornings are consistently cold, the Eastern Cape interior where cold and cloudy conditions reduce flat panel efficiency, high-altitude properties in the Drakensberg foothills and escarpment regions, and households with high morning hot water demand where multiple showers happen before 8am. During summer, both flat panel and evacuated tube models perform similarly. The performance gap opens in winter.

Electricity Savings

A 200L electric geyser in Gauteng running daily at R3.50/kWh costs R700–R1,400 per month. An evacuated tube solar geyser with adequate winter performance reduces backup element usage by 60–75% year-round, saving R450–R1,000 per month. At R24,990 for the unit and R4,000–R6,500 for installation, the system typically recovers its cost within 2.5 to 4 years.

Frequently Asked Questions

Q: How does the 200L evacuated tube compare to the 200L flat panel?
A: The 200L evacuated tube delivers better winter performance in cold climates. In Gauteng, the evacuated tube model can produce 20–30% more usable hot water during winter months. The flat panel model is simpler in construction and performs comparably during summer and in warmer regions.

Q: Is this suitable for a large family?
A: The 200L model is well suited to 3 to 5 people with average usage. For households of 5 or more with heavy simultaneous morning demand, consider the 300L flat panel model.

Q: What happens on a rainy or overcast week?
A: The backup 3kW electrical element will heat the water as needed. Connecting a Geyserwise MAX controller (available separately) allows you to schedule the element to run during off-peak hours or when solar inverter power is available.

Q: Does the 30-tube collector take up more roof space?
A: A 30-tube evacuated tube collector is typically 1.9m x 1.5m — similar in footprint to a large flat panel but mounted on a rack frame. Confirm roof space and load capacity with your installer before purchase.
