Compares the Vaillant aroTHERM Plus monobloc and aroTHERM Split heat pumps as platforms for active cooling.

Vaillant aroTHERM plus is a monobloc (refrigerant stays outdoors, hydronic
connection indoors); aroTHERM split has refrigerant pipework indoors and out.

- Both are reversible and support active cooling.
- Both need the cooling resistor and installer activation to cool.
- aroTHERM plus avoids site refrigerant work; split involves F-gas work.
- Confirm exact cooling requirements with a Vaillant-approved installer.
