Propane produces no carbon monoxide--only carbon dioxide and water--and propane generators for indoor use are available. I am considering a portable tri-fuel (gasoline, propane, natural gas) 6000 Watt generator. I have a submerged 300 (or 500?) gallon propane tank in the yard that I no longer use for heat--only hot water and cookstove. When burning propane, I could run it indoors, but I like the portability and flexibility of being able to run on gasoline (outdoors), too. I'm wondering if I could tap into (or steal) the propane line to the hot water heater in my basement to run the generator indoors. The engine is an 11 HP Honda OHV, producing 72 decibels at 20 feet. For large generators the recommendation is usually to not rely on a low-pressure propane feed, since they need a good and steady supply of fuel. I assume the line to the water heater would be considered low pressure.
Here's the generator I'm looking at: http://www.generatordepot.us/winco-hond ... pss6h.aspx
. The existing electrical panel is close by--about 15 feet from where the generator would be. I'd put a transfer switch there to run the well pump, and basement and first floor lights and outlets. At full load, the engine burns 1.9 gallons of propane per hour.
Anybody have an opinion about whether a low pressure line would run such an engine reliably? Can the line to the water heater be shared--for example by removing the cap at the bottom of the propane supply to the heater in the picture below?
