XELEX XP0
Central Heating System Additive
XP0 Central Heating System Inhibitor, leave in protection.
XP0 is a high performance BuildCert approved central heating corrosion inhibitor. It is formulated to protect and improve overall central heating system operation and efficiency. XP0 gives excellent performances in every type of water (hard, soft, and demineralised) and is compatible with aluminium and non-metallic components.How much XP0 do I need?
XPO is sold in ready to use 500ml bottles suitable for a typical 3 bedroom home with upto 12 radiators (100 litre capacity). Larger systems will require more XPO according to the system volume. Recommended concentration is 1% although it will not be harmful to the system in greater strengths, but there will be no increase in performance or protection. Commercial and industrial applications tend to have larger pipework and hence a larger system volume. If unsure of volumes this can be checked by contacting the office.
How do I add it to the system?
XP0 can be added to the system in various ways. For an open vented system with a header tank the XP0 can be added directly into the tank. For a sealed system, mostly with a condensing boiler, it can be added either via a filling loop, magnetic filter or by draining some water from the radiator system.
How long does it take to start working?
It will start working straight away and when the boiler is turned on and the system pump is operating it will circulate the additive throughout the system. Any radiators that are isolated, or the TRV turned to zero, need to be turned on to allow the fluid to flow for at least 20 minutes before turning off again.
Can I check the concentration myself?
Yes, a simple test kit,is available to identify that your XP0 level is corrected and providing the protection required. Also available for commercial systems.
Will it need topping up?
Normally the answer is no unless the system has been drained.
How long does it remain working?
As long as the system remains intact the XP0 will continue to carry on working to protect the components in the system.
If I replace my boiler and keep my radiators do I need to add more XP0?
In most cases the boiler will have been isolated from the system whilst the changeover has occurred but the heating system will not have been drained completely but it is still recommended that fresh XP0 is added. If the system is being drained it is advisable to use a cleaner, either XP3 or XP4, depending on the age of radiator system prior to adding XP0 inhibitor. If an inhibitor is already in the system it will not react with the cleaner.
It is highly recommended that when fitting a new boiler you should also fit a Xelex Magnex filter.
Will the Xelex test kit detect other brands of inhibitors?
The Xelex test Kit will detect other brands of inhibitor. If you are unsure of whether a system has been treated, it is best to drain the system and add fresh XP0 Inhibitor or alternatively add XP0 to the existing water, you cannot overdose the system.
Does adding XP0 affect my boiler warranty?
No. XPO is safe to use with any type of boiler, even those with aluminium components.
All boiler manufacturers recommend the use of inhibitor.
Can I add XP0 at the same time as a cleaner (XP3 or XP4)?
No. XP0 should only be added after the system has been cleaned and filtered when the system is being topped up. If however an inhibitor is already in the system it will not react with the cleaner.
XELEX XP1
XP1 Energy Saving Central Heating Additive
XP1 is an advanced formulation energy saving central heating additive. It is produced and tested to the highest standards to improve overall central heating system operation and efficiency. ‘Typically, up to 15% savings can be achieved when adding XP1 in to your central heating system ’. XP1 gives excellent performances in every type of water (hard, soft, and demineralised) and is non corrosive and is compatible with all inhibitors and will not affect metallic, non-metallic or aluminium components.
How Does XP1 work?
XP1 reduces the surface tension of the water improving thermal contact, making it possible to reach into the micro cracks and other imperfections within the system pipe work and radiator surfaces. This makes more effective use of the heat generated by the boiler.
Do I need to clean the system before adding XP1?
XP1 will work more effectively if the system is clean and the thermal contact is optimised. It should always be added to a system containing an inhibitor. XP1 will work with any branded inhibitor already present in the system at the correct concentration. If there is no inhibitor or the concentration is low then XP2 should be used as this is already combined with an inhibitor at the correct strength.
When do I need to clean the system?
In general it is best to clean an existing system to optimise the thermal contact and gain the best energy saving performance from XP1. Once the system is cleaned and flushed XP2 should be added. The advice is as follows: Brand new system – use XP2 only. Adding XP2 to an existing system depends on how long the system has been installed and whether there has been an inhibitor added previously. Less than 6 months since installation or power flushing has occurred then it is recommended to first clean with XP3 then flush before adding XP2. Older systems should be cleaned by using XP4 flushing thoroughly to remove debris and then filling using XP2.
How much XP1 is needed?
A 500 ML bottle of XP1 is enough to treat a 100 Litre system, or a domestic installation of 10-12 radiators. Larger or commercial systems will require more XP1 according to system water volume,
What type of systems can XP1 be used in?
XP1 is used in indirect heating systems only: Open systems or Sealed systems:
XELEX XP2

Do XP3 and XP4 Cleaners need to be flushed out of the system?
Cleaners should be allowed to circulate around the system for at least 1 hour for new systems, or up to several hours/days for existing and or very fould systems, then drained out and the system flushed thoroughly with clean water before adding XP0 or XP2 inhibitors.
Are Xelex Cleaners and other heating products suitable for use on systems with plastic pipe (or Speedfit fittings) and Aluminium components?
All Xelex products have been formulated for use with plastic pipe work and Aluminium components, and are compatible with Speedfit fittings.
What is the difference between XP3 and XP4?
Cleaner XP3 is formulated for use with new and existing systems that have been recently fitted. XP4 is a heavy duty cleaner, and has been developed for use with heavily sludged or contaminated systems and is ideal for use with powerflushing equipment.
Why would I need a powerflush?
Powerflushing is the fast and efficient way to remove longstanding sludge and debris from older existing systems in order to restore or maintain the energy efficiency of your central heating system. The procedure/ time taken to powerflush varies depending on the size and condition of the system. It is recommended to powerflush before installing a new boiler to protect and extend the system’s life and maintain the boiler’s Sedbuk energy efficiency rating.
Can you add XP0 inhibitor at the same time as a XP3 or 4 cleaner?
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

XELEX XP5
Limescale Preventer Central heating system Additive
XP5 has been formulated as a multipurpose treatment to eliminate limescale and boiler noise in all types of central heating systems. XP5 gives excellent performance in every type of water (hard, soft, demineralised). A build up of limescale in a system has an adverse affect on thermal contact, conductivity and stability. A central heating system cannot perform at its optimum best with limescale deposits making it inefficient and costly!
When should I use XP5?
XP5 should be used if you live in a hard water area, and if your boiler has become noisy due to a limescale coating on the heat exchanger.
How should I use XP5?
XP5 can be used in conjunction with .XP0 corrosion inhibitor and XP2 corrosion inhibitor including energy saving additive, it is added to and left in the system alongside these products.
How much XP5 should be used?
XP5 should be added to the system at 0.5% .of system volume, 500 ml will treat a system size of up to 100 litres. 500 ml of XP5 contains sufficient treatment for a typical heating system with domestic hot water cylinder and up to ten radiators. XP5 is used as a supplementary product together with XP0 and XP2, specifically for water with calcium hardness higher than 200 ppm.
How do I get Xp5 Limescale preventer into a system?
XP5 Limescale preventer can be added to the system in a number of ways. For sealed systems use a by-pass feeder or a 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 Dosing vessel to inject via the filling loop or other access point.
How long can XP5 be left in the system?
XP5 should be left in the system indefinitely.
My boiler is noisy, what should I use to clean it?
If the oldest part of the system (pipes/radiators/boiler) is less than 15 years old, clean the whole system with Xelex XP4 System Cleaner, heavy duty cleaner. Finally treat with Xelex XP2 inhibitor including energy saving additive and XP5 limescale preventer in combination.
Can I overdose with XP 5 Preventer?
No! Overdosing is not detrimental and it is important to ensure that there is always sufficient treatment present.
What causes knocking noises in boilers?
Boiler noises result from localised boiling of the water. This happens when the inside surface of the boiler becomes too hot due to scale or baked on sludge deposits. All systems over five years can suffer noise and new boilers in old systems are especially vulnerable. We recommend you clean the boiler and system with one from the range of the Xelex Cleaners, or add XP2 and XP5 to the system as an additional measures and to enhance efficiency and savings.
