Buffer + DHW combined vessel — floor-standing, vertical
Available volumes: 50+150 · 70+210 · 120+330 L (buffer + DHW)
Function of Buffer and DHW Tank 2 in 1:
- Combined function of both buffer water tank and hot water tank with coil.
- Same functions as previous buffer tank and DHW tank.
Advantage of Buffer and DHW Tank 2 in 1:
- Integrating the buffer water tank and coil water tank into one, it is a higher integrated product.
- Using this tank, the pipeline will be in better order.
- It occupies smaller area comparing with using two tanks.

Design benefit: The 2-in-1 replaces two separate vessels in a single footprint. The thermal barrier between buffer and DHW sections is maintained by wall construction — no mixing between circuits.
