Grundfos MixiMizer represents a real
breakthrough in the efficiency and
effectiveness of radiant floor heating.
At the heart of the system is the Outdoor
Reset Control which ensures the heat
supplied to the building is equal to the
heat loss of the building.
The Outdoor Reset Control continuously
"fine-tunes" the indoor heating
water temperature based on the changes in he
outdoor temperature. When the outdoor
temperature drops, additional hot water is
automatically injected into the heating
distribution system, so that the desired
indoor temperature is maintain.
key to any hydronic or radiant floor heating
system is its ability to provide consistent
comfort, without requiring frequent
adjustments by the homeowner. The
Grundfos MixiMizer, integrated pump and
mixing control system, delivers that
Grundfos has made it possible to integrate
the pump and mixing control. This new
technology adjusts the supply water
temperature by varying the speed of the pump
to match the rate at which the outdoor
temperature changes. This is
accomplished in a mixing loop within the
heating system. As the need for heat
increases, the MixiMizer Control speeds up
the pump at a rate to match the heat leaving
the living area, injecting more hot water
into the heating system. Also, as the
need for heat decreases for that area, the
MixiMizer Control slows down the pump rate
to match the heat loss, injecting less hot
water into the heating system. Maximum
control for maximum comfort...consistently!
MixiMizer from Grundfos is the only pump and
controller system of its kind. This
single-unit construction greatly simplifies
installation time and wiring complexity.
