The Genesis II diesel hot water and air heater uses a diesel water furnace to heat 12L of glycol stored in an insulated stainless steel tank. The glycol is maintained at 80 degrees by the furnace and is then used to heat water via an inbuilt plate heat exchanger.

The system will heat up in less than 15 minutes and from that point delivers hot water on demand, even at very low flow rates – something an instant LPG heater cannot do.

The Genesis II can be set up with either a Belief (Chinese) or Eberspacher (German) furnace.

Pair the Genesis with a Bricor low flow shower head to have super water-wise showers – only 2.3L/min. Great for a caravan or boat where water is limited.

By adding in a Kalori fan head, the Genesis diesel hot water becomes an effective air heater, giving off up to 4kW of air heating from the single quiet Kalori Silencio 2 fan head.
