Webasto as floor heater

Hi!

The van I’m looking has a webasto engine heater. I’m wondering if it would be possible to remove it from the engine bay and use it as a water-based floor heating unit?
It means I don’t have to spend 500+$ on a diesel heater and I really prefer heated floors.

I assume it heats coolant/antifreeze and circulates it though the engine cooling system? Burns diesel? If so, just leave it where it is, cap the hoses in and out of the engine, and run new lines from it under the floor. You may have to add a reservoir to be sure the lines stay filled, and provide a place to add the 50/50 antifreeze. Could also simply tap into the lines going into the engine. That way your engine gets the benefit too. Probably a reason it’s there for the engine.
