Yes it is. It works like an normal radiator, but then inside the water. It can produce 15 KW, so that should be enough .Looks spectacular!
I'm interested in your heating system; is that a heating coil in there?
As David said, the return of one of my tricklefilters flows along the heater.
The front of the heater will also be coverd in 3D background. On the right side (the way the waters flows) will be grate .
