For domestic systems, one litre, one rapid dose, or one 275ml tube of Sentinel X100 Inhibitor is sufficient to treat a typical system of up to 10 radiators (100 litres). Larger domestic systems should be dosed with twice this amount.
It is not advisable to add an inhibitor at the same time as a cleaner, simply because the cleaner will need to be flushed from the system in order to complete the clean. The inhibitor should be added during the final system fill only after the cleaner and the debris it has removed have been drained from the system and the system flushed. However, if you have already added an inhibitor to a system currently undergoing the cleaning process, there is no detrimental effect to the system or the cleaning process.
It is perfectly safe to use Sentinel X100 Inhibitor on systems with standard plastic plumbing pipework.

We recommend checking the concentration levels of Sentinel X100 Inhibitor at the annual boiler service to ensure maintained protection. Levels can be checked using a Sentinel X100 Quick Test Kit and the system topped up as appropriate.
The Sentinel Eliminator is not dependent on its magnets for debris capture; four hydrocyclones capture debris by separating it from the system flow. The four magnets are strategically placed below the hydrocyclones in order that captured debris is better retained as spreading the magnetic field using multiple, smaller magnets enables better retention. Many filters on the market rely solely on a single central magnet to capture only magnetic debris and their performance falls off as the magnet becomes coated.
Chemicals which come in Sentinel Rapid-Dose or concentrate cartridge format can be dosed into the Sentinel Eliminator. The following products are available in Rapid-Dose aerosol cans and concentrate cartridges: Sentinel X100 Inhibitor, Sentinel X400 System Restorer, and Sentinel Leak Sealer.
Full installation instructions are provided with the unit. A video showing this process is also available.
It is advisable to install Sentinel Eliminator on the system return pipe to the boiler rather than the flow pipe. We suggest this because the filter’s primary function is to capture any circulating debris and prevent it from entering the boiler.
A central heating filter separates out solids from the system water, preventing them from accumulating in radiators and causing inefficiency or causing damage inside the boiler.
It is perfectly safe to use Sentinel Eliminator on systems with standard plastic plumbing pipework.
It is perfectly safe to install Sentinel Eliminator on systems over 20 years old.
The dimensions of Sentinel Eliminator are:
32.2 cm (with T-Piece and isolations valves in vertical position)
25.1 cm (with T-Piece and isolations valves in
Using multi-cyclonic technology to remove debris from the system water as it passes through the unit, and strategically arranged magnets to hold the debris in place inside the collection bin.
The Sentinel Eliminator comes with a 10 year manufacturer's guarantee. You can register online for this guarantee.
Sentinel Eliminator is designed to operate at flow rates from 5 litres/min up to 25 litres/min. Within these parameters it does not present significant restriction to flow and pressure drop across the unit is no greater than 100 mbar. Please consult the Product Fact Sheet for more details.
If left to circulate through the boiler and central heating system, debris can interfere with, or damage thermostatic and diverter valves, restrict heat transfer in the boiler and even provoke corrosion causing inefficiency, leaks, noise and more. Sentinel Eliminator removes this debris before it reaches the boiler, protecting the heart of the central heating system.
Fitting a filter is a way of future-proofing a system against unforeseen circumstances which may lead to corrosion and formation of debris – an engineer may not top up inhibitor levels after carrying out work on a system, or there may be a minor leak which causes problems over time. With this in mind, we believe that whether you are installing a new system or servicing an old one, you should always fit a central heating system filter to protect the boiler.
Sentinel Eliminator is a central heating system filter to protect the boiler and other system components. It captures any circulating debris and prevents it from causing problems.
Following the installation of a Sentinel Eliminator, the unit should be flushed periodically during the first few days to remove initial captured debris and thereafter servicing should be undertaken on an annual basis. We recommend that you do this at the annual boiler service and the collection chamber should be emptied at this time.
The guarantee period on the Sentinel System Filter is 12 months.
Sentinel ScalePro and Sentinel SESI use a natural electrolytic process to prevent limescale encrustation. The unit imparts a tiny amount of soluble zinc which interferes with the crystal structure of scale-forming water hardness minerals so that they cannot form a hard, tenacious scale.
The guarantee period on Sentinel SESI is 5 years. You can register online for this guarantee.
For domestic properties in hard water areas, Sentinel SESI is designed to protecting the hot water circuit and appliances. The Compliance Guide to Part L1 of the Building Regulations states that measures must be taken to minimise limescale build up in areas where water hardness exceeds 200ppm, so it is important to treat water using a recommended technology such as electrolytic devices to achieve this. Check your local water hardness levels at www.helpwithhardwater.co.uk.
A Sentinel ScalePro unit has a life expectancy of approximately 10 years, although the battery will need replacing in this time.
It is perfectly safe to use Sentinel ScalePro on systems with aluminium components.
It is perfectly safe to use Sentinel ScalePro on systems with standard plastic plumbing pipework.
Softened water gives this sensation as fewer solid particles will be in contact with the skin.
Softened water is potable and safe to drink.
For anyone advised to have a low sodium diet it may be best to limit softened water intake and take medical
advice if needed, however this is in exceptional circumstances only.
Sentinel Sumo is WRAS approved, meaning it complies with the high standards set out by water regulations
It is not recommended to use softened water for watering gardens, etc. in order to avoid increasing salt consumption for activities where softened water is not necessarily required.
The addition of salt to the dishwasher is not required as the Sumo will provide softened water to the unit.
Consult the dishwasher’s user manual regarding water hardness and program the dishwasher to the lowest level.
The fitting of a separate tap is not a legal requirement.
It is recommend that you also have access to a non-softened water supply.
There is a requirement for your water supplier to be able to test the water supply to your home.
Like a boiler, we recommend that a softener is serviced annually. This service is to avoid any degradation of the unit to ensure smooth running.
An average family of 4 people will need to purchase a block (or similar) of salt every 4 to 5 months (3 bags of approx. 25 kg per year).
We recommend checking the manufacturer’s instructions for the boiler to ensure compatibility.
The Sumo softener must be fitted with a by-pass when filling the primary circuit, so that it can be filled in
accordance to the boiler manufacturer’s recommendations.
A softener will not remove existing limescale. Softened water can help to eliminate limescale deposits over time but the length of time of encrustation as well as other factors will limit the effectiveness of this.
A separate descaling may be required to resolve this issue.
Sumo softeners contain resin beads that hold sodium ions. Once hard water passes through these resin beads inside your water softener, the resin beads hold onto the calcium and magnesium in exchange for sodium. Once this exchange process is complete, the water exits the softener system and is now soft.
A competent person should determine the most suitable location for the installation.
Access to a waste water pipe is required.
The 2 items with costs are salt and the usage of water for regeneration.
On average, for a family of 4, with a water hardness of 300 ppm, we estimate monthly water cost at less than £5.
Using softened water can protect your appliances from lime-scale which can improve their energy efficiency and reduce maintenance costs.
A Sumo water softener has a standard 1 year warranty, which can be extended to 2 years when the client registers their warranty via the Sentinel website.
Yes - Sumo can be removed from a system and reconnected to another system. As the unit is designed to deal with a wide range of hard water, moves to other areas where water hardness is different to original siting is not an issue.
Ensure the removal and repositioning is carried out by a competent person.
We recommend only using salt provided in tablets, blocks or pellet form - not granular salt.
Do not use salt for dishwashers.
Specialists in water do not have any evidence to show that softened water exposes consumers to any
cardiovascular problems (heart attack, high blood pressure), cancers or osteoporosis.
Furthermore, the presence of sodium in water does not present any health issues, notably even in low salt
diets (user’s choice). It is important to know that a water hardness of 300 ppm, after softening, contains
0.138 g of sodium per litre. This can be signified as drinking 1.5 L of softened water per day corresponding
to an ingestion of around 0.2 g of sodium. The Food Standards Agency recommends a daily allowance of no
more than 6 g per day, for adults and children aged 11 years and over.

Almost two thirds of the UK is supplied with ‘hard’ mains water which, when heated, deposits limescale onto internal surfaces of pipework and the heat transfer sufaces of boilers, and other appliances. These deposits compromise the efficiency of water-heating appliances and systems, making them ultimately more expensive to run. Limescale is also unattractive when encrusted onto shower heads and taps and can be unhygienic, providing places for bacteria to hide.
Sentinel X300 Cleaner for New Systems has been designed for use on new systems ideally during commissioning, but also on systems which are up to six months old.
The dimensions of a Sentinel Condensafe C4000 unit are:

When dosed into a central heating system, Sentinel Leak Sealer stops leaks from minor perforations (pinholes) in pipes and radiators. It becomes fully dispersed throughout the water in the system and when it encounters a very small pinhole leak, it dries to form a soft seal. It has little mechanical strength and can therefore only seal pinholes. It works best when added to the system when it is in service because the heat of the surface metal at a pinhole leak serves to coalesce and dry the seal.
Sentinel Leak Sealer works by forming a soft seal over pinhole leaks inside the system.
It is perfectly safe to use Sentinel Leak Sealer on systems with standard plastic plumbing pipework.
Sentinel Leak Sealer should be left in the system indefinitely.
1 litre or 1 400ml aerosol of Sentinel Leak Sealer is sufficient to treat a typical domestic system of up to 10 radiators.

It is perfectly safe to add Sentinel X100 Inhibitor at the same time as Sentinel X200 Noise Reducer.
Sentinel X200 Noise Reducer gently removes the slight layers of deposit or limescale on heat transfer surfaces and alters the flow characteristics of the system water which together eliminates the cause of boiler noise.
Sentinel X200 Noise Reducer can be added to the system in a number of ways. For sealed systems use a by-pass feeder or a Sentinel Dosing Vessel to dose via the F&E cistern. For empty sealed systems, add to any convenient point before filling. For full sealed systems, use a Sentinel Dosing vessel to inject via the filling loop or other access point. Sentinel X200 Noise Reducer is also available in Rapid-Dose aerosol and Concentrate gel formats.
Sentinel X200 Noise Reducer eliminates boiler noise caused by a thin layer of deposit on the heat exchanger.
For domestic systems, 1 litre of Sentinel X200 Noise Reducer is sufficient to treat a typical system of up to 10 radiators. Larger systems should be dosed with twice this amount.
For commercial systems, Sentinel X200 Noise Reducer litre formulation should be dosed at should be dosed at 1% of system volume.
It is perfectly safe to use Sentinel X200 Noise Reducer in systems over 20 years old.
Yes. Sentinel X200 Noise Reducer can be topped up if the system water needs to be replenished, or if complete eradication of the boiler noise has not been achieved.
Sentinel X200 Noise Reducer is a highly successful treatment for curing boiler noise caused by a thin layer of limescale or other deposit on the boiler heat exchanger surface. Treating boiler noise caused by deposits with Sentinel X200 Noise Reducer will also help to restore boiler efficiency.
Sentinel Leak Sealer is ideal for use when minor leaks don’t warrant immediate repair. For instance, you may notice a weeping joint or some minor pinhole corrosion.
When investigation into boiler noise indicates that a thin layer of limescale or other deposit is the cause, rather than mechanical or design faults, Sentinel X200 Noise Reducer is a gentle but still highly effective solution.
It is perfectly safe to use Sentinel X200 Noise Reducer on systems with aluminium components.
