Heat source on a water loop

I'd like to model heat reclaim by adding a constant heat source on a water loop. I don't want to model a heat source in a zone that passes through the air loop to the water loop.

Is this possible in OpenStudio / E+ (even if using a work-around)? The only thing I can think of is to add a pump with very low efficiency, and all of the inefficiency going into the water as heat.
