Sentinel X400 System Restorer Gel is formulated for cleaning existing central heating systems with a significant amount of corrosion debris affecting the efficiency of the central heating system and boiler. X400 System Restorer Gel is ideal where a new boiler or pump is to be fitted to an existing central heating system or where radiators have developed cold spots due to the build-up of sludge, a black iron oxide deposit commonly found in untreated central heating systems.
One cartridge of Sentinel X400 System Restorer Gel is sufficient to treat a system with 8 to 10 radiators; larger system will require a second cartridge to sufficiently restore the system to optimum performance. Once the system has been dosed the X400 System Restorer should be circulated around the system at normal operating temperature with all the valves fully open and the pump turned to full flow for at least 2 hours or until the system is restored to optimum performance. For badly affected system the circulating time should be extended, e.g. up to 4 weeks; however X400 System Restorer Gel will not be able to clear completely blocked pipes. There are no limits to the number of times a system can be treated with X400 System Restorer Gel but it is recommended that for best results that it is used in conjunction with a power-flushing device. The X400 System Restorer Gel is simple to use and is simply added to the system via a radiator air bleed valve or the filling loop with an adaptor and caulk gun.

At Boilers2go we recommend the Vaillant ecoTEC Plus Gas System Boiler for small homes with a single bathroom where living space is limited and where the user wants the convenience of instant hot water. Also as the ecoTEC Pro Gas Combi Boiler is a condensing boiler, capable reclaiming latent heat from the flue gases, the user will benefit from reduced fuel bills and carbon emissions. This also gives the ecoTEC Pro Combi Boiler an energy efficiency rating of 'A' on the SEDBUK scale. Also Vaillant provide a 1 year manufacturer's guarantee a worthwhile extra in providing peace of mind to consumers who opt for the ecoTEC Pro Gas Combi Boiler.
