The Joule product range offers both a single stream and a dual stream pump station.
The flow rate required on a system is typically 1 litre per minute, per square metre
installed. Therefore a 2-12 litre pump station will be sufficient for systems up to 12m².

Connections of flow and return pipe work to the pump station are made vis the ¾” flat
face thread connection on all points apart from the connection directly underneath the
pump. This connection is to be made with 22mm smooth tube.
When locating the pump station consideration should be given to future access for
maintenance. It is best practice to locate the pump as far downstream the system as
possible away from the collectors to help reduce the amount of high temperature fluid
that comes in contact with the pump station. If the distance between the collector
and heat store is short (>5m) then running extra pipe work over and back inside the
attic space to increase the linear distance between pump station and collectors is
recommended.
