Cause
Solution
Boiler does not come up to temperature.
Green or soft wood is being used,
Use dry, hard wood
The boiler is at temperature and is
steaming
Poor water circulation (excess fittings, too
small of pipe, improper installation)
Change to a larger pump, use sweeping bends
instead of 90’s
Poor burn time
Green or soft wood is being used,
too much demand on unit,
Use dry, seasoned hard wood
lower home temperature set points, insulate home
better
Boiler is up to temperature but little to
no heat in house
Poor circulation (A simple test can be done
to determine if this is so: touch the pex line
leaving and returning to boiler. There
should be little or no temperature
difference)
Heat exchanger plugged
Improperly designed installation
Not enough insulation in building
Change to a larger pump
Clean and add a y-strainer – be sure to use
treatment!
Reduce number of 90’s & T’s used
Add insulation to structure
Boiler over heats
