It makes sense that a taller chimney would put a slight vacuum on the unit at all times helping keep the smoke moving forward. It's worth a try and keep an eye on it.

Best I could do is get you the email address of the individual that contacts me.

Hey RSI, thanks!
I was thinking of trying that, glad to hear that works.

My Edge 750HD is still running perfectly for 6 weeks now. Very little creosote building up on the air channels. Nothing but a little fine dust in the rear access heat exchangers. I have no intention of taking off the primary elbow or pulling the air channel panels until the end of the heating season. Small amount of ash scooped out of reaction chamber. Very easy to do through both the front and now rear access doors. The wifi XP is a great feature and chart looks great. I attached a shot of the dashboard  and chart so you can see what it looks like.

Just curious, why would it collect at the permanent magnet any more than it does at the electromagnet of a regular pump?

I have two Armstong ECM pumps on my boiler and so far been going good. I guess time will tell but I have not heard or any excessive failures of Alpha pumps and they have been getting used on outdoor boilers for quite a few years now.

Even if you have an 007 pump already, that doesn't necessarily mean that is is the best size. Actually an 007 is almost never a good choice for an outdoor boiler since it has a max of less than 10' of head pressure. But if the pipe is short and has minimal restriction you can get 3-5 gpm with them.

It's a circulator, not a centrifugal. It will not purge air any better than any other circ we use in these systems (but they do claim to self purge the pump housing, which is feasible). I see a few of them here and there, seem to be decent for what they are and the price is good compared to an Alpha if your only objective is saving a couple bucks on power. I would never put one on a mild steel boiler though, any ferrous metals in the water will collect at the ECM (magnet) motor and wreck it

Those flowmeters aren't always accurate, but .6 is about max flow for a 300ft loop of 1/2". At that rate, you've got about 7 feet of head to overcome which is just out of range for speed 1. You could drop to speed 1 and slow the flow a bit while still probably maintaining temp, but it'll broaden your delta T and isn't really worth it unless that 50 cents a month is a big deal to you. I'd leave it on 2 personally

Id like to talk to them about buying the site. Is that possible?

Iím in contact with the admin about twice a year, then he reports back to the board or the trustees? I have a feeling a family trust or something actually owns it.

What pump do you have now?
I have the Taco 007 now.
Is that similar to the Grundfos Alfa?  The Grundfos Alfa does the exact same thing, variable speed on demand.  Not only am I hoping that it'll save a bit money but when all of the zones call for heat, it'll ramp up to meet the demand.  Roger

Yea from the youtube  I saw on it it is variable speed on demand. They claim it will self purge any air pockets or shut down if it gets any clogs. In the video they talk about some energy savings rebate for it, I need to see if that is true. I have a heat exchanger in the basement separating the house from the boiler so I don't need a pump running at max speed 24/7. The good part is it is the same size as the 007 .
