Heat Pumps:High-Pressure Switch and Low-Pressure Switch

Safety controls for any fuel gas fired boiler

High Steam Pressure: A pressure switch in the steam chamber stops the burner if the pressure gets too high. If the burner continues firing even when steam flow is low, the boiler pressure can build and the vessel can explode. Low Water Level: A level switch stops the burner if the boiler water level gets too low.

Boiler pressure too high? Here's why & how to reduce it

May 26, 2021 · For low pressure – top up using the filling loop. For slightly high pressure when your boiler is off – bleed the radiators before resorting to a potential costly repair. Never undertake any other work on a boiler and call an engineer if in any doubt whatsoever. Relax – minor pressure …

The Basics of Boiler Safety – Technology Transfer Services

Boiler water is up to the correct level, closing the low-water cutoff switch. The low-water light (panel) is off. The operating limit pressure control (steam boiler) or the operating limit temperature control (hot water boiler) and high limit pressure or temperature control are below their cutoff setting.

A List of Boiler Safety Controls and Their Functions - R.F

High-Oil Pressure Switch (HOPS) – Complements the low-oil pressure switch. It works similarly to the high-gas pressure switch with a setting above normal operating pressure. Ensures the burner is not receiving excessive oil that is not properly mixed with combustion air causing excessive pooling and sooting and a possible fireside explosion
