The radiator heating circuit is supplied by
the on-site circulation pump.
The underfloor heating circuit is supplied
by an on-site circulation pump, which is
controlled by the extension kit.
The DHW circulation pump is connected
on site.
Low loss headers are available in
conjunction with Modular Divicon or
individually as an accessory.
See Vitotec or Vitoset pricelist.
For further details regarding low loss
headers, see page 118.
