Glow-worm Gauges

Within this Glowworm Gauges category we list either Temperature Gauges, Pressure Gauges or combined Temperature & Pressure Gauges. The pressure gauge is a visual means of checking your boiler/system pressure and will normally read between 1 to 1.5 Bar for most Glowworm sealed system and Combi type boilers. Some boilers will have either a separate temperature gauge or more commonly a combined Temperature & Pressure Gauge, the temperature gauge is normally for showing the temperature of the central heating system water. All our Glowworm Gauges spares are new and genuine manufacturer spares.
