It depends on the "boiler" but many of them can be cord and plug connected. If so, I'd have a regular wired to the house receptacle for the normal power. I'd wire a outdoor generator input back to a second receptacle next to the boiler. Then after you fired up the generator, you could just go pull move the plug over.

It's illegal to snake extension cords through walls.

You're talking about a 'suicide cord' because both ends would have plugs on them.

You need a transfer switch which aren't that expensive, and you can probably use them with any generator. Size is a consideration in terms of what you're going to run on it, you may have to go around turning off breakers.

I recommend making sure your generator provides
'clean' sign-wave power, so as not to destroy the control
board on your new boiler.

It's not a suicide cord if he uses a "generator input" receptacle outside of his house, as ronnatalie said.

Then you'd use a normal extension cord to run from the generator to the inlet.
The inlet would be wired to a normal outlet inside the house (isolated from the house's electrical system), where the boiler would be plugged in.

When you say you want water available, do you have a well pump? And do you want to power that as well?

Thank you all very much, greatly appreciate your comments. Weedmeister, we are on town water, the it will be indirect tank in conjunction with the boiler.

I am NOT talking about a suicide cord (and doubt the original poster was talking about one either). He wanted to run a regular extension cord. Not legal either, but not insane like the suicide cord.

He doesn't NEED a transfer switch if he uses cord and plug connection to move the load.

True. That would be the only way.

Good news, but did you actually run the generator and
have it run the furnace/boiler? Now's the time to
find out, and not on January 22nd, when it's
12 below and your power goes out.

An interlock is only better than a transfer switch in that it is substantially cheaper.

And having a receptacle fr regular operation and then using an extension cord for generator hookup is all the lockout an transfer you need for safety.

Just not for simple convenience.

YUP, you da man, Brickhead.
Nobody else, on this 'FRIGGIN PLANET',
is as smart as you.
All new posts should go directly to
your personal e-mail.
Afterall, none of the rest of us
even have a clue.

'Afterall, none of the rest of us

You obviously do not have a clue.

Congratulations.

Thanks Brickhead,
That means a lot, coming from you.

Thanks again.

Ibpod; great suggestion, thanks for the tip. We just got our electrical needs done and now off to acquire the generator. We are going with the Honda, EU6500 series on the advice of many others.

Hopefully it wont be needed; but its good to have on hand.

Jim

How much will the EU6500 set you back?

$3,899, plus sales tax, to the good old state.
