Caution!
The capacity of the built in water recirculation pump is
600 l/hr at the 20 kPa setting. The maximum loss of the
flow and recirculation system occurs at 65°C flow and
60°C return (3.kw). A greater loss will cause a lower
return temperature and therefore a longer loading
period.

consists of a buffer tank, plate heatexchanger and a boiler.
The System is suitable for use in any building with
medium to large water usage, such as swimming pools,

Installing 2 Thision EVO WH in parallel
The Thision
EVO
WH is a standalone unit that functions
exceptionally. Where there is a high demand for hot water there
is an option to connect two units together in parallel. It is
essential that the units are connected such that flow is distributed
evenly through both units
Ensure that pipework is equal from both units to the
secondary flow and secondary return connection.
