Frequently Asked Questions
What does a water-source heat pump connect to?
A water loop shared with the other units.
It draws heat from that loop or rejects into it.
Each unit serves its own zone.
Each reverses independently of the others.
All of them share the same pipe.
Why is the shared loop the interesting part?
Heat rejected by one zone becomes another's source.
The loop moves energy across the building.
Nothing has to be thrown away and replaced.
A warm core and cold perimeter do this all winter.
The more the zones disagree, the better it performs.
What keeps the loop at the right temperature?
Equipment at each end of the band.
A tower or fluid cooler sheds surplus heat.
A boiler or other source tops it up.
Neither runs while the building is balanced.
That balance is the design intent.
What kind of building suits this best?
One with simultaneous heating and cooling demands.
A deep floor plate with an exposed perimeter.
Offices, hotels and mixed-use buildings qualify.
Zones that all want the same thing benefit less.
Diversity between zones is the asset here.
What does distributing the units cost?
Many small machines instead of one large one.
Each needs access for service.
Each needs a condensate route.
Sound in the space below matters for every unit.
The maintenance count is the real trade.
What is the advantage of that distribution?
A failure affects one zone only.
Units are individually replaceable.
No single item stops the building.
Capacity can be added zone by zone.
Work can be staged over time.
How does this differ from a ground-source system?
The source is a building loop, not the earth.
No drilling or ground array is involved.
Loop temperature is actively maintained.
The heat comes from other zones, not the ground.
The unit hardware is often very similar.
