Boiler Low Water Alarm in Lower Houghton
The low water cut-out trips and stops the boiler even when the tank has water. This page covers how we diagnose and repair it on steam systems in Lower Houghton.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Lower Houghton is a high-value residential pocket of Rosebank, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
