All about Benchmark
When the installer has finished installing your product,they
must complete the Benchmark commissioning checklist.
We recommend they use the digital Benchmark app as this
provides a record which cannot be lost. You can also use the
app to see the history of your installation and servicing.
If this isn’t possible, they must fill out the Benchmark
checklist at the back of the ASHP Installation and Service
Manual. Benchmark provides you with evidence that:
The installer is competent, qualified and committed
to providing high-quality service
The installer works to the Benchmark Code of
Practice
The product has been installed correctly
The installer has given you a demonstration
of the product and how it works and the handover
is complete
Whether your installer uses the Benchmark app or
fills in the paper copy, we may ask to see it if you
need to call us out under warranty.

Even if you are having a complete new central heating
system, your installer must clean and treat your system with
chemicals and fit a magnetic filter. At each annual service they
will check the water in the system, to make sure there is no
build-up of sludge and debris.
Protect your central heating system
Power flushing – a power flush is a cleaning process
that removes sludge, rust and debris from the pipes
and radiators in your heating system.
Inhibitor – once the heating system has been
cleaned, it should be treated with an inhibitor to
protect it and prevent further corrosion.
Magnetic filter – will collect magnetic debris in the
system water.
Limescale prevention – in hard water areas, a scale
prevention device on the mains water will ensure
limescale does not build up in your heating system.
What is sludge?
Corrosion occurs naturally when metal and water meet. If left
untreated in your heating system, corrosion can form into
black iron-oxide sludge (Magnetite) and other debris. This can
build up in your heating system causing:
• Damage to your ASHP
• Damage to radiators that could cause leaks
• Damage to radiator valves
• Blocked pipework in the central heating system.
Why you need a magnetic filter
A magnetic filter will attract the magnetic debris in the
system water, helping to protect it
from sludge.
Note: Your warranty does not
cover damage to your ASHP
caused by sludge.
