Closed-loop heating systems require proper glycol concentration to prevent freezing and corrosion. Riley Plumbing Heating And Air installed an Axiom flush-out feeder system at this Zephyr Cove property. The device automatically maintains correct glycol levels in the heating loops. The crew mounted the feeder unit, connected it to the system supply, and filled the reservoir with the appropriate glycol mixture. The digital controller was programmed for the system volume and glycol percentage. Initial flush-out removed old fluid and introduced fresh treated solution. The feeder monitors concentration and adds glycol as needed when levels drop from minor system losses. Manual glycol maintenance requires periodic testing and adjustment. Automatic feeders eliminate the monitoring burden and prevent freeze damage from diluted solutions. Properties at elevation face greater freeze risk during power outages. If your boiler system lacks automatic glycol maintenance, call now to discuss installation options before winter conditions test your system protection.
