All I really want to do is to heat water, for domestic hot water and
some room heating in the winter. There isn't much sun around here
most of the time, but there is a lot of wind.
I have had a little experience with small wind generators and know that
the battery issues add cost and complexity, making small scale wind
power hard to justify.
Are there any wind generators around the 1000 watt or higher range that
don't need batteries for storage, where I can just run the electrical
power from the generator to a heating element?
Thanks in advance.

All of them. Wind generators don't need batteries.

Now, to be fair, a 4 foot baseboard rad draws no less than 1000 watts
when running. A typical electric water heater draws over 4000.
You're asking alot from that wind turbine...

Certainly, you can. And as another poster mentioned, pretty much any of
them will do it. The trick will be to have the amount of electricity
generated actually *do* anything noticable.

I am using permanent magnet motor 3 phase 640Volts and 25 Amps with 10 ft.
propeller, When it runs at 200 RPM it generates 128-130 Volts that I cycle
out to 110Volts with voltage controller, and use this 110 Volts to heat my
water heater, I have 2 water heaters and it works pretty good. Water heaters
are also connected with utility power in case no wind. Once water
temperature reach the desired setting it disconnect the power to heating
elements and divert the power to dummy load that I have in garage to heat up
my garage. I have noticed my utility bill is reduced to pretty decent level
since I added this setup.
My next project is to add another wind generator that supplys power to my
airconditioning and heating system and that is a tough one. :-)

as said, any. If you wish you could dispense with the heating element
and pass the electricity straight through the water.
Immersion heaters in UK are normally 3kW, some a bit less, and take
60-90 mins to fully heat a tank from cold. If we use say 1.5 tanks of
hot a day, (1.3hrs x 3kW), then you'd need about
3kW x 1.3/24 = 160 watts average throughout your 24 hr period.
