Schwank Patio Heaters- FAQs

Q1: What does single and two stage mean?

A:  single-stage mode is for a steady heat, and a two-stage is a (high/low) model that can be turned up or down and controlled with the flick of a switch. A 2-stage heater, which is best for commercial applications, allows the equipment to operate at a lower capacity to bridge the minor gap to reach setpoint. This 2-stage, in turn, reduces the amount of fuel that would normally be used in a 1-stage to reach setpoint. It also helps reduce short-cycling effects that can harm the equipment/component life. Imagine getting to a 100% only to turn off completely, then turn on again (via purge cycle) and back to 100% – this is exactly what occurs in a 1-stage system. This strain is additive and degrades components, eventually leading to failure.

Please let us know if you have any questions!
