Zoned heating systems
BoilerMate is available in a no clock/multi-zone
version for use where a property has to have
its space heating zoned. Where this appliance
version is to be used it is recommended that
the BoilerMate is located on a raised platform
in the cupboard creating a space below the
appliance to locate the zoning equipment.
The recommended height of the platform
from the fl oor is 250mm. The platform must
be constructed in a material that will not easily
deteriorate if exposed to moisture. It must also
be capable of supporting the weight of the
appliance when full. Details of the weight when
full is provided in section 1.2 Technical Data.
Connecting the zones to the BoilerMate.
The space heating fl ow should be taken from
the BoilerMate connection into the space below
the platform. The fl ow can now be split into the
appropriate amount of zones and a controlling
zone valve fitted to each branch. Each flow
can then be piped to its radiator zone and
the heating return brought back to the space
below the platform. The heating returns can
now be connected together before a single
connection is made to the heating return on
the BoilerMate.
A typical way of providing heating and hot water
time control is shown below. However, other
methods can be used such as using a 3 channel
programmer if required.
