Modular Heat Pump Chiller Selection Questions
When should I choose two-pipe instead of four-pipe?
Choose two-pipe when the connected zones can share the same heating or cooling mode. Choose four-pipe when the building needs hot and chilled water at the same time.
Which buildings suit this capacity?
Offices, schools, hotels and multifamily buildings with larger seasonal heating and cooling loads can use this model with suitable hydronic terminals.
Can it be part of a boiler upgrade?
Yes. It can provide electric hydronic heating and add chilled-water cooling. A retained boiler can provide supplementary or backup heating as part of the project design.
