Dave Clarke & Son Ltd are proud to work with Sentinel offering total solutions for central heating and domestic hot water
Are your rooms cold in Winter when they should be warm?
Are you worried that your boiler is not working efficiently or it could break down when you need it most?
Are you having a new boiler fitted or work carried out on your system?
Would you like to save on your heating bills?
Would you liek to save energy and Co2?
Would you like to reduce your carbon footprint?
If the answer is yes to any of the above questions then ask us about the benefits if cleaning and treating the system with Sentinel.
Of course you probably don't know what is going on inside your central heating system, you may assume that itis working to maximum efficiency and is unlikely to fail, but....
Many central heating systems have never been cleaned and therfore will be operating below their optimum efficency level. Cleaning a dirty system can improve effectiveness by up to 15%, as shown by independent tests. Fitting Sentinel into your system will help ensure it is running as effectively as possible.
Corrosion, scale debris and sludge in the system are the most common sources of problems that affect the energy efficiency and effectiveness of the boiler and heating system. You may notice cold spots at the bottom of your radiators, a noisy pump or just that the system does not heat your house the way it used to.
It is not unusual for a radiator with several years service to have a significant level of debris present. This debris will prevent the radiator warming the room. The two images above illustrate this. The radiator in the 'Before' image has a build up of sludge which is clearly producing a massive cold area on the radiator. The 'After' image was taken after the heating system had been cleaned with a Sentinel cleaning product.
The UK Building Regulations Compliance Guide now states that when installing a new boiler onto a new or existing central heating system the minimum provision for boiler efficiency, system circulation and hot water storage is that the system should be thoroughly cleaned and protected with corrosion inhibitor.
A general purpose treatment for total protection against scale and corrosion in all types of indirect central heating systems, including those containing aluminium. Will extend the life of the system, and ensure maximum efficiency and minimum fuel usage. Once added, X100 never needs to be replaced unless the system is drained down.
X300 System Cleaner
Sentinel X300 System Cleaner is specifically designed for new central heating systems. It flushes out flux installations debris from new indirect central heating systems. Helps to maintain system efficiency and conserve fuel.
X500 Inhibited Antifreeze
Provide protection against scale and corrosion in all types of indirect heating systems, including those containing aluminium components, whilst preventing freezing. It is effective at preventing hydrogen gas production.
X800 JetFlo Ultimate Cleaner
X800 JetFlo, voted Corgi Domestic Product of the year 2006, is a heavy duty, 'one visit' cleaning formulation designed to remove corrosion deposits and scale in domestic central heating systems. specially designed to complement power flushing using a unit such as Sentinel's JetFlush 4.
X200 Noise Reducer
A unique, life-long system treatment for the elimination of limescale and boiler noise. Safe to use in all types of indirect central heating systems it will quickly pay for itself in reduced fuel usage.
X400 System Restorer
Specifically designed for existing systems Sentinel X400 is a non-acidic treatment for cleaning older heating systems, restoring circulation to radiators and pipework. A ruthlessly efficient way to eliminate the build up of magnetite sludge.
X800 JetFlo Ultimate Cleaner
Designed to clean and protect underfloor heating systems. Sentinel X700 is a solution containing a stabilised biocide for use in underfloor heating systems. The growth of bacteria and fungi in these systems can cause problems such as blockages of the pipe work, manifolds, valves and heat exchangers. Systems can also produce unpleasant smells or suffer from corrosion of the heat exchanger and manifolds. This can severely disrupt the smooth and efficient operation of the system. Sentinel X700 is specifically designed to eliminate these problems in underfloo heating systems.
