Howdy,

Yes, this is OT, but you folks seem to know everything...g

I need to get an automatic backup generator, but my needs
are unusual:

The fully automatic units I can locate are all in the range
of 7000KW.

I need something on the order of 5-10KW. So, compared to the
"standard" residential backup unit, the one I am looking for
is really tiny. But, anything over that (approximate)
capacity would just be money wasted.

Might any of you suggest sources for such a small (but fully
automatic) generator?

Very sincere thanks,
Not sure about the automatic part, but Honda might have the answers.
They make damn good generators:

Also, I saw a water powered sump pump as backup on "This Old House"
several months ago. The house water supply pressure drove the thing
when the power was out for the regular sump pump. Wouldn't solve the
fan issue though - I'm guessing you're trying to prevent a possible
freezing problem? Do a google on "water powered sump pump" and you'll
get lots of sources.

Hi Doug,

Yes, freezing is (half) the issue.

I have a second (unused) flue in our chimney and could
easily install a gas heater using it, but...

It is my understanding that those heaters must have
electricity (to run the fan).

The water powered sump pump confuses me though:

If we had an extended outage, we would not have any water
pressure (or at least would not have it for very long.)

If I had electricity to pressurize our water supply, I would
just use it to power the pump I now have (unless I am
misinterpreting your comment about water pressure.)

You will see other issues elsewhere in the thread.

Sincere thanks,

I misunderstood - I thought the sump pump was to prevent flooding. It
sounds like the pump is for a well, not a sump? The water powered pumps
work if you have city water and therefore water pressure independent of
your power. They are a solution to prevent flooding of a basement for
example if the power is out for the electric sump pump.
