Our mission is to make best practice solutions simple. To achieve optimum performance and reliability for domestic central heating systems, follow our best practice process of clean, protect and maintain whether you’re commissioning a new system or revitalising an old one.The benefits of adhering to this best practice include improved performance, increased energy savings, and longer system life. It is recommended thatX800 Fast Acting Cleaneris used in accordance with standard cleaning and commissioning protocols such as BSRIA Guide “Pre-Commission Cleaning of Pipework Systems”. The unique composition of Sentinel X800 Fast Acting Cleaner provides a powerful penetrating cleaning action. It will restore more even heat distribution to a property, keeping occupants warmer and bills lower. The rapid, heavy-duty clean that Sentinel Fast Acting Cleaner provides is ideal when commercial heating systems require immediate, unscheduled maintenance. litre, 1 300ml aerosol or 1 275ml tube of Sentinel X400 High Performance Cleaner is sufficient to treat a typical domestic system of up to 10 radiators. Larger systems should be dosed with twice this amount. For optimum results, systems should be cleaned and thoroughly flushed in accordance with standard cleaning and commissioning protocols such as BSRIA Guide “Pre-Commission Cleaning of Pipework Systems” or similar Water Treatment Guidelines from industry organisations such as the Industrial & Commercial Energy Association (ICOM).

Limescale and corrosion are the two main causes of central heating inefficiency, leading to radiatorcold spots, boiler inefficiency, a noisy system and a multitude of other problems. Once a system hasbeen prepared using one of the cleaners from the Sentinel cleaning range, it should be protected withSentinel X100 Inhibitor to prevent the occurrence of limescale build up or corrosion. After cleaning, the system should be drained and flushed until the water runs clear. On refilling, the system should be treated with Sentinel X100 Inhibitor or Sentinel X500 Inhibited Antifreeze. Sentinel X100 Inhibitor should be dosed at 1% of system volume; ie. 1 litre per 100 litres of system water. Circulating debris in central heating systems can cause wear and premature failure of pumps, valves and heat exchangers. Sentinel's filters are the perfect filter solution to protect the system against magnetic debris. Sentinel X400 High Performance Cleaner restores a more even heat distribution to the house, keeping the property warmer and bills lower. Reviving an old heating system is a more cost-effective way to return warmth to a property than the installation of a whole new system.Vortex250 units feature an integrated isolation valve, a voiding the need for a strip down service; and a front-facing magnet, ensuring that where space is at a premium, no further space is required as the magnet can simply be removed at the front. Sentinel's range of filters is crafted to fit any situation. The filters we offerrange from ultra-compact, where space is at a premium, through the compact Vortex300 and the larger Vortex500, which is also suitable for heat pump installations.

The associated ACOP goes on to explain that the ‘temperature in workrooms should normally be at least 16 degrees Celsius unless much of the work involves severe physical effort in which case the temperature should be at least 13 degrees Celsius.’Sentinel X800 Fast Acting Cleaner should be used as a 1% solution in mains water to remove typical levels of deposits of iron oxide and calcium carbonate. Where systems are badly fouled, a higher concentration (up to 10%) is recommended. X800 Fast Acting Cleanershould be circulated, preferably at normal operating temperature, with all valves open and the pump turned to maximum flow for a minimum period of 3 hours or until satisfactory performance is restored. Limescale and corrosion are the two main causes of hydronic heating inefficiency, leading to radiator cold spots, boiler inefficiency, a noisy system and a number of other problems. Once a system has been prepared using one of the cleaners from the Sentinel cleaning range, it should be protected with Sentinel X100 Inhibitor to prevent limescale build up or corrosion. General purpose treatment for total protection against scale and corrosion. For use in all types of indirect central heating systems, including those containing aluminium. Non-acidic.
