Effecta Lambda

[Eric Johnson]

Here's a link to the English brochure on the Effecta Lambda that I saw at the show in Sweden. Not much detail, but you can see how the boiler works. I wish they provided more technical information on the Lambda sensor.

Interesting. Some common themes here:

1) Sloped primary floor (Curses that they didn't figure that out until after I got mine)
2) Turbulators (ditto)
3) Fan is in exhaust - negative cabinet pressure
4) Servo controlled dampers rather than variable speed fans for primary / secondary balance
5) Lambda sensor
6) Smaller than anything sold here. They've figured out that bigger is NOT better, and almost no one needs more than 50,000 BTU/hr.

I really wonder how they keep the lambda sensor alive. I've been convinced for years that an O2 sensor is the only way to truly control these things, but I've seen usable lifetimes of less than 100 hours in a gasification boiler. Maybe they keep it behind a shutter and only expose it for a few seconds every so often, or perhaps there's a way to keep the nasties from condensing on it during startup. Looks like it's a heated sensor - that could well be part of the necessary protection.

Most of the residential boilers on display were in the 35KW range. The EKO being shown was the 25.

There are some pretty old farmhouses in Sweden and Finland, so I assume they have similar problems retrofitting insulation. They're probably smaller, on average, than farmhouses in the U.S. and Canada, but not by all that much. I suspect that the long winter nights in that part of the world are also a factor.

Pretty sexy. Got that stainless appliance look almost, rather than the industrial box look (ya know- if looks matter to ya).

That thing is really sharp.

I could imagine Jags on a drunken evening, throwing his laundry in the front of it, expecting it to "dry". :wow:
