Independently like the Froling (or effecta or varm)?The Vigas does adjust the primary and secondary air.
Yes, There are two inlet holes one for primary and one for secondary. The srevo motor moves the shutter to open or close to allow more or less air as the signal from the o2 sensor is sent to the controller then to the servo motor.Mike in May we will be at the loggers show in Bangor.You should stop by and see the Vigas in the flesh.

If I didnt know better Id say that sounds like a salesman trying to confuse the facts.
Not trying to hurt any feelings. Just trying to understand how these boilers work.
To each his own. I wouldn't think twice about replacing the circuit board, any sensor, or any part of my system. In fact.. I'd be apt to fix any of that stuff myself.. and hire out any plumbing.It's just that I dont trust the longevity of the electrical/computer components. And personally would prefer a simpler system that I can repair myself.
I've been lurking here from time to time over the years! This thread has a lot of the info I was looking for.
I am also looking at boiler options, and after lurking for a few weeks I'm leaning towards a unit with lambda control.
My design heatload is around 20kw, but my 21kw electric boiler never runs fullout. I have infloor in the basement and garage slab,
and in 1+1/2" slab on 1st floor. 10% south facing triple gazing helps a lot. Whole house is 2200sq ft + garage which I have not yet heated. The total electric bill for weekend use is $800/year including heat and domestic hot water +2-3 face cords of hardwood for the EPA fireplace when we are there on weekends.
As in DanW's case the garage is not heated, basement is 55F, and the whole house is 52F for 4 days a week.
As we are starting to spend more time there I'm looking into finally getting the wood boiler the house was designed to have when we built it in 2008.
So my questions are:
1) Besides Froling and Vigas are there any others with lambda control?
2) How much can I count on the basement slab as a heat sink?
3) Does anyone know of a Froling or Vigas distributor in Eastern Ont or Quebec? I have Ted Kestor's name from Brockville posted by bbarbeau, thank-you.
4) Does Bioheat have USA distributorship or USA and Canada distributorship for Froling?
Thanks for all the great info!
Hey Dan,
My apology to you if I have gummed up your thread.
While researching the potential benefits of having the lambda sensors and advanced controller, I see this outfit selling in North America.
http://www.loppernorthamerica.com/index.html
The name is Lopper and they offer the lambda controlled, modulating output wood boilers. For those who truly enjoy the light and walk away feature, this outfit has a self loader for you (1/2 face cord hopper). The boilers are available in (3/8" - 10mm) or (7/8" - 20mm thickness.) It looks like the loading unit may be a standard feature.
