Hot water heater location - how much space in layout to allow for maintanence?

I'm doing a remodel and may need to move my hot water heater to accommodate the changes.

It's currently in a 33x33 enclosure in the corner of the garage and I need to know how much space I have to leave in front of it to permit maintenance or eventual replacement.

I'll try to visualize it...

How far does the (new) wall of ?'s have to be from the front door of the enclosure (pointed to by >) so that a plumber can get the old one out and put a new one in?


Thanks!

It needs enough combustion air. What HWH are you going to purchase?

They are sealed combustion chambers now.

I don't believe there is a code requirement like there is with an electrical panel. You would need enough room for a person to work and enough space for the WH to be removed.

Just a guesstimate but I'd say at least 30-32" depending on the actual diameter of the WH. You don't want it so tight that it leaves no room for your hands to grab it. Maybe WH diameter +4" or so?

The water heater is already in place (50Gal) in a 33x33" box (properly vented and everything). It's probably 24" diameter. It's gas. Ventilation / code issues are all addressed already.

For replacement / maintenance, I had figured at least 36" for workmen to slide it out but since they aren't that heavy empty maybe 30" would do it...
