This element is intended for the 5 litre semi-automatic Comel ironing boiler specified on this page. It should not be assumed to fit other boiler capacities, automatic models or different brands. Before ordering, compare the existing boiler type and element arrangement with the machine documentation or seek confirmation from a qualified repair engineer.

Yes, the replacement heating element is supplied with a gasket. The gasket is important because it provides the seal between the element and boiler opening when correctly fitted. Using the included gasket avoids relying on an old, compressed seal, which may no longer provide a reliable watertight connection after the element has been removed.

Replacement may be considered when a compatible boiler is no longer heating correctly or a fault has been traced to the element. Poor heating can also arise from electrical controls, wiring, scale build-up or other boiler components, so the cause should be diagnosed before ordering. A competent engineer can test the element and confirm whether replacement is appropriate.

Professional fitting is recommended because the work involves opening a steam-generating boiler, fitting a watertight gasket and checking electrical connections. The boiler should be isolated from the electrical supply, fully cooled and depressurised before any work begins. Correct installation helps prevent leaks, electrical faults and damage caused by operating the boiler without a proper seal.

Water quality can affect the service life of a boiler heating element because mineral deposits may build up on components exposed to heated water. Follow the boiler manufacturer’s guidance on suitable water and routine descaling, where applicable. Regular maintenance can help keep the boiler operating efficiently and may reduce the likelihood of scale-related heating problems in commercial ironing use.
