There's is 110 sorry I thought your were talking about the existing heater.Pedal power to the squirrel cage blower?
I pulled up their site but the installation manual page is giving me a 404. I'm scratching my head on why this unit would need 220v. The blower motor is the bulk of the electrical needs and they could get by with a 110v motor.
220v inverters are available so you can use that instead of a genset but they're typically more expensive (compared to 110v)
I just talked to my friend who has a similar unit. He said his uses 110v.
Thanks for the heads up. Here's the link.This is a newer version of the one we have. Ours is about 8 years old and has only 1 blower.

Here's the link to your stove. Looks like it heats water for a radiator type heating?The first one you listed looks like a gasifier like my Tarm. They are built to burn hotter, make almost no soot and use much less wood. The second one you listed looks like a standard add on wood stove. That probably explains the price difference. Some companies don't use the word gasifier since they are not technically gasifiers, but you check the efficiency to see if you are comparing apples to apples.
