Has anyone purchased one of these new pressurized OWB within the past year or so? If yes, how do you like it and did it meet your expectations? Did it operate as advertised? Thanks. Roger

I've read info on the CleanFire unit too and they definitely are thinking outside of the box. But I haven't heard from any users. I'd love if someone would chime in.

One issue with a pressurized, and I may be wrong, but legally can a homeowner even hook their own up? I see more insurance issues than code issues unless some places are a LOT more anal than where I live.

Roger, it is not ready for the market yet, they are working out some bugs before releasing it and yes they are thinking outside the box!
-
Is this the CleanFire or another model we are talking about? If the CleanFire, are they changing it from what they have been selling? I looked at one another dealer had at a fair here last year but he didn't have any covers off so couldn't really see much.

What are the benefits of having a pressurized system?
-
The thought is elimination of the plate exchanger, low water volume and affordable anti freeze ability and low pressure to match the existing system.

RSI - I am referring to the CleanFire unit.
fireboss - In the non-pressurized systems oxygen is always being introduced into the water which leads to corrosion. That's the reason for the water treatment. Once the pressurized system is full of water air cannot get in to corrode things; the water is considered "dead". Also, the circulator doesn't have to work that hard to push water through the zones. Another benefit of a pressurized system is the water can get a bit hotter than 212 F degrees before it boils. I believe water under pressure at 12 PSI will boil somewhere around 230/240 degrees F.

Has the clean fire been pulled from market? I thought I remember it being listed on the epa phase 2 list. Still haven't seen any numbers out of the pm 250 egr

The last I knew they were doing some more work on the Clean Fire and I just did the Bangor show with Brian and didn't think to ask him about the EGR 250, they do have another new small chip burner that should be in for testing now, it ran very impressively at the show.

I wonder what kind of numbers they could have gotten without the cat. The cat seems like it would need to be vacuumed every other cord burned which entails shutting it down to perform. They are also pricey to replace.

I believe you are exactly right with the corrosion issues and the heat issues but as for the circulatory system not having to work as hard is not true. It is a system neutral just like a car, it has to push as hard as a non pressurized system as the return is pressured also. One more thing about pressurizing water is that you relieve surface tension on water causing heat to absorbs faster and release faster. I can get almost 20% heat dissipation from my water to air intercooler on the race car when it is pressurized rather than not. The pump on the other hand will only pump 10gmp no matter what. 40 amps pressurized or not. That water will get up to 300 degrees from the supercharger at some points. Without being pressurized it will boil out after a full run.
