The Aquastat on Your Weil-McLain Boiler

The aquastat monitors boiler water temperature and controls the burner to maintain set-points and high-limit safety, mainly on conventional and cast-iron boilers. A failed aquastat causes overheating, no heat, or erratic temperatures.

On Weil-McLain systems — including models such as ECO, ECO Tec, Ultra — a failing aquastat often shows up as low water cutoff trip or related symptoms. We diagnose it precisely and install the correct genuine Weil-McLain part.
