The High-Limit Thermostat on Your HTP Boiler

The high-limit thermostat is a safety control that shuts the burner off if water temperature exceeds a safe maximum, protecting the boiler and home from overheating. Repeated trips signal a circulation or sensor problem that must be fixed, not bypassed.

On HTP systems — including models such as UFT, Elite Premier, Versa Hydro — a failing high-limit thermostat often shows up as ignition lockout or related symptoms. We diagnose it precisely and install the correct genuine HTP part.
