Model Selection
The suggested model sizes shown in the tables
opposite are based on a typical daily hot water
usage and on the assumptions that the heating
system is correctly sized and that the thermal
store is fully charged to at least 75°C by the main
heat source.
When selecting a solar model, it is important
to check the dedicated solar volume (shown in
table on pages 6-7) complies with the Building
Regulations ADL1 Domestic Building Services
Compliance Guide.
The suggested model sizes are based on
typical hot water usage. For high specifi cation
dwellings an increase of one model size should
be considered.
General Design Considerations
As a general rule, the cupboard footprint needs
to be a minimum of 150mm wider, 80mm deeper
and 80mm taller than the unit selected.
The base chosen for the Torrent should be level and
capable of supporting the weight of the unit when
full of water as shown in General Data.
General Restrictions
a. An ascending spray type bidet or any other
appliance with a Class 1 back-syphonage
risk requiring a type A air gap should not be
used.
b. Torrent should not be used where steam is
the primary heating medium.
