First off I will say I love this boiler, but it is not without issues, maybe some here can chime in. also we bought this boiler used, it is a 2008 model and we are on our 2nd season with it, no storage hooked up yet, but I do have 2 1000 gal NH3 tanks.
First issue is the controller, it seems that the temperature on the display is never right almost always 5-15 degrees high. (I put another port in the supply next to the overtemp aquastat to verify) even though I know it is not right I do not like having to have the boiler set at 195 (was idling at 204 when i got home the other night) to keep enough heat to the fin tubed parts of the house when it is -20. is there a way I can make a temperature sender in the port in the supply line talk to the controller I.e. what values would the temp probe need to have to work with the controller? And I see in the wiring diagrams there is a place to land a thermocouple, I think to shut the fan down with low EGT's, anyone done this?
Might just be the nature of the beast, but seems to blow lots of junk into the chimney (going to change the elbow to a cleanout T, did not have one handy when I put it in), this morning I had to pull the baro damper out and vac all the stuff out of the elbow. a lot of it makes it up and out which does not really bother me, as the cornfield over there does not care what the shed looks like.
and to add insult to injury I replaced the nozzle this fall, and could only get 3 of the 4 holes to line up in the refractory (and yes I did provide the serial #), does not really affect operability that I can tell, just bothers my irrational mind.
Not trying to go on a rant here, overall very happy with the boiler, and the amount less wood we go through is easily 1/3 of what the old hardy used to burn. we were thinking about getting another one of these for the other farm (for out tenants, not us), but am wondering if I should just put in a waste oil boiler for them, as I am afraid of what issues might crop up with the wood boiler that I have to run back and forth to dink with.
I will try to get some pics of the shed and boiler tomorrow, as I know you guys like pictures. Hopefully it will make up for my long windedness.
