Tankless water heater in basement - casing ideas?

I'm planning to finish my basement, and have run into a couple of problems I'm not sure how to handle. One of these is, they've put the tankless water heater in the corner of what was planned to be a spare play/bedroom. I'm not sure what the most aesthetically pleasing way would be to build around it while still maintaining accessibility. I had thought about building a drywall frame around it with a door ... but it seems a little strange to have a tankless water heater in the corner of the bedroom altogether. Is this normal for underground rooms?

I had considered moving the heater across the basement, but that would require running 5" (maybe larger) pvc through about 15 floor joists to allow for venting ... not really an option.

Is it operated by natural gas or electricity?
Electricity
In that case a shallow closet would likely suffice!
Why would they put a 5" vent pipe on an electric heater?

The vent would indicate to me that you have a high efficiency gas heater (pvc vent) in which case will absolutely need combustion air.

Is there anything I can look for that would give this away? I see it's plugged into the wall, so I assumed it was electric.

H/E gas fired, tankless water heaters require electricity for venting the combustion gases.

An electric unit would have a very heavy cable, similar to what is found feeding an electric range in the kitchen.

It seems likely that you have a gas fired heater and the space and venting requirements will much different, than what is required for electric.
Hm, yeah it is a standard 120V plug. And we do have natural gas heat pumps.

You should try to find the make & model & model # and track down an install manual. It will give you clearances and venting requirements.

How's your woodworking skills? I think in your situation, I would build a bookcase/hidden door with side vents. Something like this:

I love that. What software are you using?
Google Sketchup. Obviously this is just a quick mock-up. Took about 10 mins. Exposed hinges are just for reference...
