...Label your zones.
you are installing a multi-zone system, ensure that you label each pipe with its
corresponding room zone, as you lay it. Failure to do so, can result in
confusion when installing your wiring centre at the end of the installation.
...Ensure the floor is clear of
debris prior to laying a low-profile system.
benefit of a low-profile system is that it doesn’t require any levelling compound
or screed and you can tile directly on top of the system. However, if a floor
is not cleared, swept / vacuumed prior to laying the low-profile boards, debris
can cause the boards to rock, which in turn can lead to the floor finish cracking.
...Leave the system in full
end user may not be familiar with how to operate the system at first, so ensure
that you / the tradesmen leave the system up and running. Programming any
thermostats will also leave the customer with peace of mind. If you need any guidance
on Snug thermostats or controllers, our technical support team are always happy
to help, on 01772 761 333.
...Take short cuts when
commissioning the system.
you are commissioning your water underfloor heating system, it’s important that
you fill each pipe individually, one at a time, to push all the air out of your
system. If you fill all pipes at once, to save time, you’re at risk of retaining
air in the pipes, leading to an inefficient system and cold spots.
...Forget to carry out
the pressure tests.
This process is often forgotten, especially when tradesmen
are busy and are keen to move onto their next job, but it’s a vital process.
Not only does it provide the information needed to complete the warranty for
the water underfloor heating system, but
it will allow you to check for leaks and ensure the
pipes reach maximum expansion. The pressure test should be carried out
in 2 parts, firstly at a 3 BARS pressure, inline with a standard water tap
pressure. It should be tested for a minimum of one hour before checking for any
leaks and then increased to 6 BARS, as a stress test for at least 1 hour, again
checking for any puddles or leaks. Once complete, the system should be brought
back down to a normal working pressure. These pressure tests should be
completed prior to laying the screed, so that any issues or leaks can be easily
resolved and there is confidence that the system is in full working order prior
to becoming less accessible, once the screed is laid.
