Types of Central Heating Accessories

Installing a filter on your boiler will help prevent blockages caused by debris in the system. Magnetic filters are available for wet central heating systems, suitable for horizontal and vertical pipework.

Thermostats are commonly used with an immersion heater boiler to prevent the system from overheating, ensuring the safety of your home. Auto air vents bleed excess air from the central heating system, reducing noise, corrosion and maintenance costs.
