The boiler at this South Lake Tahoe residence was heating slowly or failing to reach temperature. Riley Plumbing Heating And Air scheduled a morning diagnostic appointment with advance notification. The crew examined the Munchkin condensing unit and the radiant heating manifold distribution. Low flow through the system pointed toward circulation issues rather than boiler output problems. The circulator pump was running but moving water inefficiently. Sediment accumulation in the heat exchanger was restricting flow and reducing heat transfer effectiveness. The technician flushed the exchanger and cleaned the pump impeller. Water chemistry was tested and found outside acceptable parameters. A water treatment solution was added to prevent future mineral buildup. The boiler fired properly and all zones received adequate flow after the service. Condensing boilers require cleaner water than conventional units. Neglecting water quality leads to expensive repairs. If your heating contractor hasn't discussed water treatment for your boiler system, call now to prevent performance issues before they develop.
