Water that keeps changing temperature mid-use is frustrating and usually points to flow sensing or scale rather than the burner.
Our licensed technicians cover every Surrey neighbourhood — including Guildford, Fleetwood, Cloverdale, South Surrey, Newton, Whalley — with genuine OEM parts and a workmanship guarantee.

What you can safely check first
Beyond these safe checks, do not open the boiler or touch gas, electrical or sealed components — BC law requires a licensed gas fitter. Call us for a proper diagnosis.
