Hello zoo, waross is correct; I agree more with his second recommendation, viz., you should find a local expert in power factor penalties.
My reference was to a power factor correction unit that connects at the point of common coupling, meaning where your electrical services and your power...
Hmm, have I not seen threads in these fora relating to commercially available small scale power factor correction units for use at Point Of Common Coupling [ POCC ] ? You might want to do a search . . .
Why not?
If lower valve is closed and aspirator draws water up from the upper reservoir, will it not spill over the saddle of the apogee and prime the downstream side as well?
Or am I missing something?
If a valve is placed at the outlet and closed during priming, cannot an aspirator be used at the top of the siphon to extract the contained air? This would obviate the need for a foot valve at the inlet.
"Unfired" perhaps, but not without energy input; ability to liberate steam in such volumes as needed to preclude boiler or system over-pressurization is still very much in play.
