EXINDA 4Ton R32 EVI Air-to-Water Heat Pump
Cold-climate heating. Summer cooling. Everyday comfort.
Upgrade residential comfort with EXINDA’s 4 Ton R32 EVI air-to-water heat pump chiller. It brings space heating, cooling and domestic hot water into one hydronic system, with EVI heating operation down to −25°C. Chilled-water outlet temperatures down to 4°C with glycol added for freeze protection. Inverter control follows demand, while dry-contact and 24 V interfaces simplify coordination with new or existing boiler systems.

Heat Pump Chiller Selection Questions
Can it replace an existing boiler?
It can supply hydronic space heating while adding chilled-water cooling. Review the building load and the water temperature needed by the existing radiators or radiant floors to plan the replacement.
Can I use it for a home in Quebec and keep my boiler?
Yes. It suits cold-climate residential hydronic systems, and the existing boiler can remain as supplementary or backup heating. The installer can coordinate both heat sources through the system controls.
How does it provide room cooling?
Chilled water circulates to fan coils or hydronic air handlers that cool the room air. Include condensate drainage at the terminals and insulation on chilled-water pipework.
How does it connect to existing controls?
Dry-contact and 24 V control interfaces support integration with the building’s heating and cooling controls. Use the model wiring diagram to identify each terminal and its function.
When should I compare the 6 Ton model?
Compare 6 Ton where the building needs more output. Heating load, cooling load and operating water temperatures guide the choice, rather than floor area alone.
Can the system also support domestic hot water?
Yes. Domestic hot-water integration is available as part of the system design. Coordinate the storage tank and control priorities with the space-heating and cooling requirements.
What should I send for an initial project discussion?
Start with the project location, building type and whether this is a new installation, boiler replacement or hybrid system. Share the existing terminals and available load information so EXINDA can help compare models and supply the technical package.
