Separate Circuit And Emergency Switch For Pellet Boiler?

[velvetfoot]

Can a pellet boiler be run off the same circuit as the existing oil boiler? There's an emergency shutoff switch for the oil boiler at the top of the stairs. If a new circuit is run, that would that entail another emergency shutoff?

Some thoughts: They don't consume hugh amounts of power (though I should find out how much), they won't in all liklihood be operating at the same time, the distribution pumps would continue to be powered from the oil boiler (I imagine), two emergency shutoffs might be confusing. That does bring up a point though: the fact that that the oil boiler circuit would have to be on to power the circulators.

It may be required by electrical codes for the boiler to be on it's own circuit.

Yeah, I'm figuring that might be the case.

Yeah, I'm figuring that might be the case.

Use a double pole switch so you can kill both circuits at the same time.

I used the same circuit on my install. But I have a separate service switches and overhead thermal switches for each boiler.

An emergency switch at the top of the basement stairs kills power to everything.

Neither service switch shuts power off to the circulators -- just the boilers burner or fans.


The inspector was happy with what I did.

Thanks. I still have to check out the power requirements-there's a heating element involved with the pellet boiler.
