Laars Endurance Brass Flow Switch Troubleshooting tip

Endurance flow switch

Are you having problems turning on your heat? The Laars Endurance EBP Boiler, utilizes a brass flow switch, to prioritize domestic hot water. During this stage of operation, your heating system will not provide heat because the priority is for the hot water to serve the shower, kitchen sink, laundry.

If you have no heat while all of the calls for hot water are off, unplug one wire from the flow switch and wait 5 minutes.  If the heat comes on, it’s time for a new flow switch.
