I remember seeing a fridge and being able to pull out the fridge drawers with the door in position like that, as they had the shelving of the door to suite (so the drawer in the main area would slide out and it would go in between two of the door shelves, it wouldn't hit anything) but now that i think of it, i think the issue was with the drawers in the freezer at the bottom
I think our media room is a standard window size so i think the water tank would be seen from there. gah!
I’m not sure how big yours would be, but our hot water system sits 1400 from finished floor level. If the bottom of your window is above that, you could fit it under neath maybe?
Our media window on the plans say its 2400 x 1200. I've forgotten how far down from ceiling they do the windows. I'm going to go to the display tomorrow and pick their brains about it all
Because our lot starts to flare out, maybe it can go closer toward the house near the front bedroom. I'm not sure though as i've read its better to have the system closer to the living/bathroom areas, although our sales person said it doesnt make too much difference these days
