The refrigerant conversation around VRF just got more serious.
For new VRF systems, the industry is moving away from R-410A, a refrigerant with a GWP of 2,088. Its likely successor, R-32, comes in at 675. Lower, yes, but low? No.
That is the bigger design question in front of engineers now.
If you are designing for the next 25 years, it really isn’t enough to ask which refrigerant comes next. You also have to ask how much refrigerant the building should depend on in the first place.
Hydronic systems change that conversation. Instead of distributing refrigerant throughout occupied spaces, they move energy with water and can help reduce refrigerant-related design constraints at the terminal level.
That matters as the industry works through lower-GWP transitions, A2L considerations, and the long-term implications of refrigerant-based system design.
At Jaga, that is part of the value of low-temperature hydronics. You are not just choosing an emitter. You are choosing a different path for how heating and cooling are delivered through the building. You’re choosing for the future.
(Note the PEX pipe in this installation. It has a lifetime warranty with the building—no expensive copper pipes!)
