Description
The water switch for your air-heating coil.
The Dantherm DN10 valve controls the flow of warm water through your dehumidifier’s optional Low-Pressure Hot Water (LPHW) heating coil. Guided by your system’s heating controls, the valve’s electric actuator opens or closes to regulate how much heat is added to the outgoing air.

Ordering a hot-water coil too?
Match the heating coil to your unit. These existing CDP coil listings are separate products; check the exact installation before ordering.
Coil outputs are rated at 80/60°C water temperatures. For a CDF unit, contact us to check the matching coil.
Need us to install it?
We offer installation of this part where suitable for your project. It is an optional extra, quoted separately from the valve. Contact us to discuss your dehumidifier, heating circuit and fitting requirements.
