Stainless
Steel Unvented Hot Water Cylinders
"...
the best of both worlds."
Up until now, installers and specifiers have had two choices when it came
to unvented hot water cylinders. The first is the 'standard' system,
where an external expansion vessel needs to be connected by the
installer. The second uses an internal air bubble, which removes the
need for the vessel, but introduces the disadvantage of regular servicing
to maintain the air bubble.
Now
there is a third choice... the DPS Amazon unvented hot water
cylinder is supplied with an external expansion vessel fitted inside the
unit casing, removing the need for installers having to connect the
vessel, while at the same time overcoming the disadvantage of having to
service a bubble. In other words, the best of both worlds.
The
Amazon Super cylinder has a Stainless Steel inner Vessel with a lifetime
guarantee. It is highly insulated and finished in a White Vinyl Steel
Casing and inside this casing is fitted the Expansion Vessel. A water
Inlet Control assembly with filter and back feed protection is supplied
for site installation.
