Beware of some energy-saving claims
From time to time, various companies come through the area
selling products with claims of extraordinary energy savings.
If it sounds too good to be true, it probably is!
Chelan PUD conservation staff can help you evaluate the cost
effectiveness of energy-efficiency products and decide whether
they’re appropriate for your lifestyle and the
area’s climate. It’s also a good idea to contact
local retailers for price comparisons. Many window installers
from out of the area charge significantly more than local
companies for the same or similar materials and work.
One tip: Read the fine print. Often, savings are calculated for
average retail rates of 10-12 cents per kilowatt hour or more.
Chelan PUD customers pay an average of 3.2 cents per kilowatt

Some products that have been sold in the area but generally
don’t work well here:

Attic shield. This is usually a radiant
barrier with a small amount of polyethylene closed cell foam.
This product will reflect some radiant heat. It has about a
quarter-inch of insulation. In our area, most heat loss is
through convection and conduction, not radiation. This
product will save an almost immeasurable amount of energy.
Roof reflector. This is a white
heat-reflective elastomeric coating. This is often used on
mobile homes and flat roofs as a reflective barrier. Works
best during times when air conditioning is needed; air
conditioning is not a major cost for homes in our area. We
are a heating climate primarily.
Souped-up surge protectors. Some companies
sell these surge protectors with capacitors to residential
customers, but they’re pretty useless in homes. Some
commercial and industrial customers with large motor loads
may see some benefit with improved power quality. Tests done
on these types of products have shown no discernable energy
savings in a residential application.
Space heaters. Out-of-area companies selling
space heaters sometimes rent conference rooms at local hotels
to promote their products. Before purchasing an expensive
space heater, compare it to similar products available at
