At GHS Group, we invest significant time in selecting the right products for our customers’ heating systems. The cleaner we use during a flush can make the difference between a simple restoration and a system with damaged components, shortened boiler life, or recurring sludge problems.
That’s why we’ve settled on Sentinel X800 Fast Acting Cleaner as our preferred choice. Over the years, we’ve compared it to other brands – including some that rely on harsher, more aggressive formulas – and the results have been consistent. X800 gives us excellent cleaning performance without the risks associated with more corrosive chemicals.
Here’s why we use it.
- Powerful cleaning without harsh acidity
Some heating cleaners use potent acidic formulations that can certainly shift debris, but at a cost. Overly aggressive cleaners can:
- Attack vulnerable metals
- Strip protective layers inside the system
- Increase the risk of pinhole leaks
- Shorten the lifespan of radiators, pipework, seals and heat exchangers
X800 takes a different approach. It works at neutral pH, which means it can break down magnetite sludge and limescale effectively without the chemical bite that can cause damage. For the customer, that means a clean system and peace of mind.
- Safe for modern aluminium heat exchangers
Modern boilers – especially high-efficiency condensing models – often use aluminium heat exchangers. Aluminium is brilliant for rapid heat transfer but is sensitive to poor water chemistry and aggressive cleaners.
One of the key reasons we trust X800 is its full compatibility with aluminium components. It gives us the confidence to restore performance in aluminium-based systems without risking corrosion or attack from acidic products.
This is particularly important when we’re maintaining systems under warranty or installing new boilers where long-term system health matters.
- Fast-acting, professional-grade performance
As engineers, we want products that do the job thoroughly and efficiently. X800 circulates quickly through the system, lifting:
- Magnetite sludge
- Corrosion debris
- Scale and deposits
- Cold-spot-causing build-up inside radiators
It restores proper flow, reduces boiler strain, improves radiator output, and often results in noticeable fuel savings for homeowners.
Its speed means less downtime, cleaner radiators, and more reliable results – exactly what we aim to provide on every job.
- Better for long-term system health
A system clean is only half the story. What happens after flushing – and how much chemical residue is left behind – matters just as much.
With more corrosive cleaners, the long-term risks include:
- Chemical attack if not flushed perfectly
- Accelerated corrosion
- Future leaks
- Boiler inefficiency
Because X800 is non-aggressive and biodegradable, it’s much easier to flush out thoroughly and leaves less behind to cause trouble later. Once the system is cleaned and refilled, we add inhibitor to protect the pipework, radiators and boiler. That combination gives the best long-term protection.
- Trusted by professionals and backed by strong manufacturer support
Sentinel products are widely trusted in the industry, and for good reason. Their cleaners, inhibitors and filters are designed to work together, and their technical support is backed by years of research into system water chemistry.
For us at GHS Group, this means:
- We know the chemistry is sound
- We know the results are consistent
- We know the products won’t void warranties
- We can confidently explain the process to our customers
That level of reliability is essential when we’re working on everything from domestic boilers to commercial heating systems.
- It simply gives the best results for our customers
At the heart of it, our job is to improve heating performance and protect the customer’s investment. Sentinel X800 helps us do that better than harsher alternatives.
With it, we regularly achieve:
- Faster heat-up times
- More even radiator temperatures
- Reduced boiler noise
- Improved circulation
- Fewer future call-outs
- Longer system life
For us, it’s an easy decision. The goal is always to deliver clean, efficient, safe and reliable heating systems – and X800 consistently helps us achieve exactly that.
