Pipework Schematic size 9 and 16 units
The heat pump has 1 inch
BSP male connections;
these should be
connected to flexi hoses.
The flexi hoses have to be
insulated to conform to
MCS.
To maintain flow rate we
recommend 28mm
pipework is used with this
machine.
NEVER use
22mm plastic tube, if you
insist on using plastic use
28mm throughout
You will also need to
install:
High resistance pump,
Expansion vessel,
Pressure gauge,
Pressure relief valve,
Filling loop,
Magnetic filter
Strainer.
Flow meter
Flow switch
2 x 2 port valves
We recommend the
system has a break in it,
you can use a header, a
buffer or a heat exchanger
to do this. This is done to
maintain uninterrupted
flow.
The domestic hot water
cylinder must be
manufactured specifically
for the heat pump and
have a coil with a surface
area of 3m^2 equivalent.
