Garage heater cycles per hour.

[randomledders]

I had a radiant tube heater installed and it got me thinking about how many cycles per hour I should set the thermostat too. I am looking for the most economic way to run the unit. I don’t really mind if the temperature is up and down a bit. Any thoughts?

The least cycles per hour the greater overshoot. Try 5 cph that every 10 ten minutes.

Maybe someone can explain why we have cycles per hour rather than just a setting for temperature differential. What is the advantage?

Because CPH and cut in cut out deferential are very different things.

Radiant concrete floor heat has a very slow response from when the thermostat calls for heat and when the air changes temperature, and after the thermostat stopped the heat continues to flow into the air for a long time. So they need very few cycles per hour but the room temp is not likely to change much than a degree as the large mass of the floor will tend to stay the same. A forced air furnace need many more CPH to keep the room with in 1 degree of the set point

I think if you worried about your heater cycling, you got other things like drafts to worry about. My overhead heater barely comes on once up to heat specified.
