I have a 1000w generator. Can I run a cord from the generator to a 110 outlet to power the boiler in my home?
No. Running a male-male cord from the generator to the outlet will destroy your generator and probably cause a fire. Your generator is not synced to the utility power coming into your home. Your boiler outlet is connected to the power company's line through your breaker box. It would be a very expensive way to run your boiler. Running a generator to power things is more expensive than using utility power. Utility power is about 10? per KW, generator power is about 80? per KW in your situation. You will have to isolate the boiler power completely from your utility power. Disconnect the boiler wire from its power source and connect it via extension cord to the generator. The generator MUST be located outdoors away from any windows to keep CO from entering the home.
Not safe, there is no breaker protecting your home from your power source because the dryer breaker is behind the dryer power outlet, not between it and your home wiring, also your probably sending 110 single phase into a 220 double phase circuit. This could be a fire hazard. On my home, I installed a master switch that isolates my system from the grid, Then I installed a 220 plug and tapped it into the two phase contact points on my meter pole. I pug a 10,000 watt engine welder into that. When the power goes out it is enough to carry the lights in my home, but not enough to run my electric furnace or A/C. I know its expensive, but hire an electrician. If you start a fire and it is determine that the cause was your generator set up your insurance carrier may not pay a claim.
It is possible to operate your boiler with a 1000 watt generator, but more information is needed. My furnace (hot water baseboard heat + domestic hot water) requires 780W (6.5A) at startup and 276W (2.3A) while operating. If yours is similar it should work fine on the generator. You need to take current measurements to determine its power requirements. It is not a good idea to use a double male cord to backfeed the outlet to power the furnace. A better approach would be to install a plug on the furnace cord that could be used with a normal extension cord to plug into the generator. Under normal use it would plug into a normal outlet powered by the house circuit.
I think a boiler has a greater draw than 1000 watts as that is only about enough to power a few lights a tv and a electric blanket. Better look and see what the draw of the boiler is.
If the rated PF (power factor) of the generator = 0.8, the useful output is 1000 x 0.8 = 800 w Then you can take power only for a 800 w boiler The output voltage of generator should be 110 v, and the Frequency of both should be equal ( 50 or 60 Hertz as the normal
