Hi Todd and all,
Since this is a renewable energy list, I think it's worth mentioning
that installing a modulating demand heater will make the installation
"solar ready".

I agree with Darryl about putting the tanks underground, otherwise they

Todd,
Having already mentioned my using the Bosch Aquastar (I'm completely

I think it would be best to contact me off-list - or on the m

I have a Bosch Aquastar hydro-ignition unit, but no solar feed. I

We've used the Flojet 24 volt quad pump, or a Flowlight Booster pump
for longer life. The tankless water heater you want is the Aquastar
1600H. Contact me for more info.

Certainly a large pressure tank(s) will allow you to exceed the pump's flow
rate until the PT reaches cut-in.

Direct pumping probably not satasify the water heaters flow requirements.
There is a 3.3 GPM version in 24 volt DC

Todd,
I have had good luck with systems like this using a Shurflo 120 volt pump
3.3 GPM but the 24 volt is simular. If you feed them from a standing tank
they seem to pump well over spec and hang around for a long time. Run the
output to as big a pressure tank as you can get. The larger the better,

Thanks for the recommendation. Does
this unit need an external pressure switch or is that integral? Does
these work w/o an expansion tank or will they cycle on/off excessively
set up in a direct pumping situation?
