The FASTflo non-condensing water heater from Andrews Water Heaters provides a continuous flow of hot water instantly and is ideal for installations that are short of space. Unlike old instantaneous water heaters, the revolutionary design measures the incoming water flow and temperature through the primary circuit board. It then modulates the burner up or down to meet the hot water demand.
Model shown is Fastflo WH42.
