From a Local Hewlett Client
“Our combi boiler kept showing E005 and we had no hot water. Called Pipe Doctor and within hours they diagnosed a burner issue and had it fixed same day. Super clean, professional, and local — can’t recommend enough.”
— Sarah L., Hewlett NY
Pro Tip:
Many tankless combi boilers have sensitive sensors that will shut down the entire unit with the slightest fault. Resetting the unit won’t solve the issue — a qualified technician will.
