TANK+ System
GreenSeed® TANK+ (by GStech) is a premium commercial hot water system that combines manifolded continuous-flow gas water heaters with a 500-litre storage tank. The heaters supply hot water on demand, and the tank holds a reserve for peak times when many outlets draw at once. TANK+ delivers up to 86 litres per minute at a 35 °C rise, with recovery of up to 5,040 litres per hour, all at full mains pressure. It runs on natural gas (NG) or LPG. Each system arrives pre-assembled on a skid or wall frame with the GreenSeed® theBRAIN controller and primary pump, ready for fast on-site connection.
