as i live in the midle of nowhere and the house is quite old we have a duel fuel heating system a solid fuel boiler with very litle controle exept burn rate and a old gas boiler upstaires as a back up . sein wat hapend in japan with the nuke station got me thinkin wat would hapen if the power failed , we are out not around to shut down the boiler the system would boil to death , me thinks to add an extra pump near the coal boiler on a hgv battery and an inverter , would the new pump hinder the flow of the main original pump, or would it alough BLOW THROUGH.

wait a mo,i just re-read your message,if your power fails,your gas boiler will shut down,so,why you worry?????

inverter would eat up the current in the battery,as was said,buy a diesel generator,it can be wired to cut in when the mains fail,this involves a few electrical mods,but a comp.electrician can do the job,what happens is this,when the mains fails,a relay trips,and starts the generator,this will power your house till either the power comes back on,(the relay de-energises,)or your diesel runs out,last one we did cost around £4.500,
but since the guy lived as you say,middle of nowhere,he was happy to pay it,you may get it cheaper,shop around.

Hgv battery wouldn't last long, better off saving up for a generator to run the pump, you can buy a gizmo that detects power failure and kicks the generator in automatically but would cost you a bit.
Dont think we are set for a tsunami for a while though!
