Condensing Boiler Plant Piping Design & Control Part …

But what about calculating boiler cycle time? Keep in mind we have to have at least enough btu storage capability in the system to keep the boiler operating within our 12° delta T range at a minimum system load – without short cycling or going off on high limit. It is the relationship between System Volume, Btu Output, and the System's Delta-T that determines what our run time should be.

BTU Calculator

However, volume is a more accurate measurement than area for determining BTU usage because ceiling height is factored into the equation; each three-dimensional cubic square foot of space will require a certain amount of BTU usage to cool/heat accordingly. The smaller the volume, the fewer BTUs are required to cool or heat.
