The Aquastat on Your Laars 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 Laars systems — including models such as Mascot FT, Mascot HT, NeoTherm — a failing aquastat often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Laars part.
