elco THISION WH, Operation And Installation Manual

Page: 8 / 30

The Thision WH is a standalone DHW charging system that
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,
gyms , sports clubs, fitness centres etc.
Hydraulic System Diagram
The Thision 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
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.

(optional sensor required)
Ensure that pipework is equal from both units to the
secondary flow and secondary return connection.

The Thision WH has been designed for ease of installation. For
the unit to provide DHW a minimum of the following is
required to be installed from the system to the unit:
1. 230Vac electrical supply
2. Mains cold water supply
3. DHWS secondary flow pipework
4. DHWS secondary return pipework
5. Gas supply pipework
6. Condense drain pipework
7. Flue gas outlet & Air intake pipework
