You have to make an
important choice when you buy an electric kiln. Do
I buy the cheapest kiln, or do
I buy a responsible energy efficient kiln? Bailey is
taking the responsible approach as a manufacturer. We will no
longer build 2.5 insulated walls for electric kilns. For a few
dollars more, you can own a properly insulated kiln in 3 brick
or 3-1/2 brick/board construction. Better yet, our 3 kilns
have such a low cost, you arent paying any more for the extra
insulation! |
| 2.5"
thick IFB has been used since the 1950s to build top
loading electric kilns. Energy was cheap then, and most potters
low fired. Most manufacturers continue to use 2.5 IFB to lower
the cost of the kiln. But this brick wastes energy, even for low
firings. It is no longer a responsible approach for kiln building.
Its not good for the planet. We need to conserve!

3"
thick IFB gives 20% more insulation compared to 2.5.
Remember that a 2.5 brick loses insulation when the element
slots are added, the extra 1/2 of solid insulation that a 3
brick provides is even more effective and important at holding in
the heat to save energy. No matter what temperature you fire to, 3
is the only responsible choice if you want to do your part in
reducing energy consumption. |

A
3-1/2 wall of brick and fiber board insulation combined
provides the best thermal profile for efficient firing of electric
kilns, especially at medium and high temperatures.
The lightweight board is highly
insulative (more so than brick) and is more effective at retaining
heat.
This lightweight wall construction
makes the kiln easier to move around while saving you money in
electric bills.
When you have
more insulation, you not only save electricity, you prolong the
life of your elements and extend the life of your relays! Its a
win win situation. |
