On top of this, any serious turbulence
can affect performance and scale up
the heat exchanger – ie where there are
tight bends in the system.
Continuous flow water systems are the
easiest system to keep scale free. Even
where a ‘turnkey pack’ system such as
the Rinnai Infinity Plus Storage is fitted
and a booster tank added the water is
unlikely to be held for 24 hours.
These systems are commonly used in
hotels, for example, to deal with peak
demand times and because they recover
in minutes due to the Rinnai unit’s
efficiency, scale is never likely to be a
problem.
To be additionally sure limescale is
never a problem, Rinnai heaters also
incorporate a scale warning device that
continually monitors the appliances
for lime scale deposits around the heat
exchanger.
Once lime scale build-up is identified, a
message is sent to the built-in interface
panel on the front of the appliance to
alert the end user that it is time to call
a Rinnai service agent to perform a lime
scale flush.
For the sake of a small cash outlay, a
zinc conditioner is a useful safeguard
and one that will give end users
additional peace of mind.
Unlike calcium water softeners, zinc
treatments need a lot less attention
and could be simply built into the
maintenance contract, thereby keeping
costs down.

For a ‘belt and braces’ solution a
continuous flow system, combined with
zinc-based treatment means end users
can virtually say goodbye to scaling.
