Yes, it's possible to install a Webasto heater into an existing engine coolant water circuit. In effect to install a parking circuit. This would necessarily add components and complication to the installation kit, but very possible.

If this is something you are considering perhaps email us sales@butlertechnik.com so we can discuss advantages/disadvantages etc.

Thank you
