Water heater problem


Hi All, I would first like to apoligize for the length of this post. I am trying to keep it short but also include all necessary information.

The house is a duplex that was modified some 35 years ago into a single family house. This was done by cutting a doorway through the hall ways.

At the time there were water heaters in heater closits in each of the two kitchens. One of these water heaters was moved into a basement below the house. Each heater supplies 1/2 of the house.

For safety reasons we would like to eliminate the water heater in the basement and run off the one remaining heater in the kitchen. The total usage of hot water consists of 3 bathrooms and a dishwasher.

The water heater closit measures 23" deep X 29"wide by 92" high with a 5"X24" vent on the top and bottom.

My thought is remove the basement heater and tie that end of the house into the other kitchen located heater (currently 30 gl). Then possibly run a recirculating pump for the side of the house furthest away from the heater and eventually upgrade the heater to a 40 or 50 GL.

1. Is this plan safe
2. Is the current kitchen closit large enough to handle the additional air usage requirements of a larger heater?
3. Is there a better solutution like outside. I believe that would require much more extensive plumbing and vent modifications.
4. We are in the Southern California area so weather is not much of a concern.

Thanks for all your help.

What is the square footage of the home?
How many people live there?
Are the 3 bathrooms full or half?

Why don't you want the water heater in the basement? You are going to want more than a 30. Forget about taking a shower, doing laundry, or running a dishwasher within twenty minutes of each other.

Air usage most likely isn't a problem. You may need to install a louver door if you don't have one already to get adequate ventilation. I'd say a 60 gallon heater will fit but you need to check your local codes to see how far from the walls the heater must be as well. Outside could work, you would have to get a building permit, pour a slab, and build a perminant shed attached to the house. I have a similar setup for a boiler in a garage apartment.

My concern with the basement is the overall height of the (old basement) is approx 6' 6" so there is no room to put it on a stand. To compound the problem the basement exits into a garage where the floor is approx 6" higher than the basement floor. In other words the bottom of the heater would be approx 6" lower than the garage floor rather than being on a stand. I hope this makes sense.

Sounds like the outside approach is a lot more involved than I thought.

The heater in the kitchen currently touches two of the walls on the back side which appear to be some type of plaster or concrete. There is a vent on both the top and bottom but I could definately add louvers to the access door also if that is needed. Would this work?

Peronsally I'd try to keep it in the basement. An extra closet in the kitchen would probably be nice?
Why does it need to be on a stand? Local code? You're afraid of flooding?
If it really needs to be on a stand they make lowboy water heaters. I know their is a 40 gallon which is only 50in. You could probably find a 75 gallon that isn't much taller. Go down to your local plumbing supply, tell them how high you can go, and find out what the biggest heater they have which fits in the space is.

Is placing the water heater in the garage an option?

Then you would typically need to raise it 18" and frozen pipes become a concern. It is less work then putting it outdoors though.

Hi Guys, My concern with the basement is the same as the garage as it is actually directly adjacient to the garage and approx 6 inches lower in grade with the only exit being into the garage. I just assumed that based on this information the requirement to have it on an 18 inch stand would apply to the basement as well as the garage for the purpose of vapors.

You probably don't need a stand in the basement. Call your plumbing inspector and find out. It's free and guaranteed to be right.
