I'm curious if anyone in the group has any impressions of tankless hot water
heaters -- specifically the electric type. Seisco (http://www.seisco.com )
seems to have a pretty decent line with knowledgeable folks and I'm
considering getting one when our current tank, gas-based unit gives up the
ghost.

An installer here in the Northwest used to install tankless electric heaters in
Arizona. He stated tankless gas heaters are much more efficient than the
electric ones. He said many areas in Arizona do no have gas and are forced to
install electric. I've had my gas tankless for 4 months and my gas bill dropped
more than 1/2 what it used to be. My heater is a Rinnai. Too, tankless water
heaters can easily integrate with solar heaters.
Good Luck!

Think about this
Electric - How much energy was used getting the electricity to you?
Electricity is a very high quality energy it is not cheap to make or use
compared to gas which is a much lower quality energy. Gas is also better
suited to making heat for hot water than electric.
You might choose to use electric but don't kid yourself about the cost
just because your bill seems low. The losses alone in the transmission
of electric from the supplier to you would keep a third world family
going for months.

I know that there are losses in transporting electricity but there are
losses in transporting everthing. Gas has losses, transporting it 2000 miles
from the gas fields through pipelines incurrs losses ranging from small
leaks through to the energy needed to run the huge compressors that have to
operate every so often along the pipeline to push the gas to the delivery
point. Local gas distribution within a city has large losses with smaller
pipes covering the whole city. You may be supprised at just how much gas
leaks out of these pipes.

Not to mention that propane (LPG) has losses due to the need for fuel to
transport and deliver the gas to the point of use. Electric hot water is
very inefficient to start off with, but if electricity is all you have then
you might as well get the most from it by going tankless and not keep the
water hot and waiting for you 24/7.
