The Hot Water Heater:
How to secure it and why.
(This is a past episode of TOW. Go to current
episode to see the newest installment or any other past TOW's.)
The material presented on this page is intended to
start you thinking about what you can do today that might someday save
your life. If nothing else, our "Tip o' da Week" can improve your
comfort level during a disaster.
We do not present ideas that cost a lot of money
(like structure reinforcement). These are "do it yourself" projects
and are relatively inexpensive.
This week we will look at the hot water heater.
You
have heard it before, "strap the hot water heater to the wall." Why?
Well there are three main reasons why you should
secure your hot water heater:
-
A water heater is a very heavy item if it is filled with water. Water
weighs about 8 pounds per gallon, and most residential type heaters hold
50 gallons. Excluding the weight of the empty heater, we are talking about
400 pounds of water! Most heaters, like my Kenmore Economizer model,
are 5 feet tall, and sit on a skimpy 18 inch base. It doesn't take much
movement at the base to cause a large swing at a 5 foot height. Once
400 pounds of water starts to swing, there is little chance to stop it.
No one wants a 400 pound object to fall on them, but there are other reasons
why you should secure the heater.
-
Some water heaters are Natural Gas models. If the heater tips over,
or just swings violently, there is a very high probability that the gas
line will not hold up to the 400 pound load, and will result in a gas leak.
One of the most frightening aspects of a earthquake is the risk of fire
from broken gas lines!
-
Finally, the heater can function as a 50 gallon water reserve that may
tide you over in a small disaster. (Keep in mind, however, that it
doesn't matter how much water is available in the basement if the structure
is damaged! It's not worth risking your life to obtain. So,
make provisions for storage of water in several locations away from
the main structure.)
DO NOT count on using the water in your houses heater. The water
supply it contains will only be useful if a disaster happens that interrupts
utilities, and does not cause structural damage! Remember that the
pipes in your house hold another 20 gallons in a typical 2 story home.
That water might also be available unless your heater falls, and breaks
the attaching pipes! Get the picture? If the heater falls and
breaks your pipes, you will loose additional water supplies!
The officially sanctioned heater strap kits use metal
straps and brackets. These kits may be required by your local building
codes! The metal strap kits require use of leather gloves and tools
for cutting the straps to length. It can be done, but it is a pain!
We
are presenting Our method for informational purposes only. You must determine
the merits of this method for yourself, and must assume responsibility
for the implementation!
No heater instillation is the same, but lets look
at how I secured the heater in my own house.
Top left support.
-
First, I bolted 2 foot long 2x4's between adjoining wall studs on the outside
of the wall. One was located about a foot above the floor, and the
other about 6 inches from the top of the heater. These 2x4's provided a
solid platform for the heater to rest against when secured to the wall.
They also distributed the load over two studs to prevent the heater from
breaking through the drywall.
-
The Concrete under my heater is not level near the wall. I needed to secure
the heater where the floor was level. This required the use of construction
shims to provide the required floor position relative to the wall. The
construction shims were installed to the cross link 2x4's and the back
of the heater. They also provided a higher degree of rotational stability
for this installation.
-
The heater inlet and outlet pipes should be flexible. They will provide
a small degree of protection from quake- induced pipe damage, but they
also allow a degree of heater re-positioning.
Bottom Right support.

Next, I installed 4 1/2 inch lag screws through the dry wall, and into
the two wall studs. Two were installed near the top, and two near
the bottom of the heater. Now, this is what made the project a breeze!
I used a set of Auto type adjustable tie downs as shown.
These items are typically used to tie down loads
in pickup beds, or trailers. Most stores that carry automotive accessories
will stock them in sets of four. You should be able to find them
in the $10-$12 range for a set of four.
Epicenter has several sets of these
tie downs in stock if you can't find them locally, and will make them available
for $10 as a courtesy to our visitors. They are not on our products
order form so add them in the comments section of the order form if you
can't find them locally. Again, you should be able to find them locally.
Now a few words of caution:
These tie downs are rated for 800 pounds working load
and will be adequate for this application assuming that you have adjusted
them to remove all slack! These tie downs are made of nylon and will
melt if exposed to high heat of flame. If using them on a gas model
heater, verify that your placement will not expose them to heat or flame!
Once the installation is complete, all that is left
is to place the tie down hooks in the eye screws and pull hard on the adjuster
strap!

That's it for this weeks "Tip o' da Week." If you have
an idea of your own for Tip o 'da Week, you can now submit
a tip! We love input and feedback! We'll format
the page and scan any images you would like to include. We 'll do
the page layout, and give you full credit!
