Bleed radiators regularly to remove trapped air, insulate exposed pipes, and lower the thermostat by a few degrees to reduce energy consumption while maintaining comfort.

Turn off the power and gas supply, then use a soft brush and vacuum to remove dust and debris. For stubborn buildup, consult your manual—some parts may require professional cleaning.

For closed systems, use a cleaning solution (like Fernox) and follow the instructions. For severe buildup, a power flush by a professional may be necessary.
