Troubleshooting
Likely causes
What to check
Check the pressure gauge cold vs hot, inspect the relief discharge pipe for water, and press the expansion vessel schrader valve for water instead of air.
When to call us
If make-up water is being added more than monthly — continuous fresh water introduces oxygen and destroys the boiler internally.
Likely causes
What to check
Compare flow and return temperatures — a wide differential with a low flow usually means restricted circulation.
When to call us
When flushing and pump adjustment don't restore the design differential, the exchanger likely needs chemical descaling.
Likely causes
What to check
Time the burn cycles — under three minutes indicates short-cycling that shortens component life sharply.
When to call us
For sequencing, buffer vessel sizing or a modulating burner retrofit — short-cycling wastes significant fuel.
