at the end of the day ill probably go with another gasser. I agree the G3 and EGR would be pushing it for 5-10k square feet. If I go that route with another gasser ill most likely do another G200 or G400. Heatmaster has been a good company to deal with and I know from personal experience that they 1000% stand behind their product which makes me feel safe investing more $$ with them.
Wreckit, what didn't you like about the BL series?? As far as HE conventionals go I think they have the best bang out there. Followed 2nd by the C series. I really like their design and especially the dry base firebox and use of refractory. The field results from customers seems positive from what I see. I have no seen on in person though.
I'm just saying I would suggest you play with one before pulling a trigger, that's all. This merely a personal opinion of course, so please take it with a grain of salt. What I have observed with the BL is this:
PROS:
1. Double door design to keep heat within the housing
2. Refractory for some storage (personally don't like it but could be a highlight for some)
3. Replaceable firebox in place
4. Multi pass flue
CONS:
1. Mild steel
2. Refractory lining (pain in the dick as far as I'm concerned)
3. No positive shutoff on the draft system. No damper, just a weighted flapper that constantly leaks air and creeps past setpoint
4. No external controls, guy needs to open the back door to check temp or shut down the fan
These are merely observations, but honestly you couldn't give me one for free. Efficiency is great and I do love the fact that fireboxes can be replaced onsite, but given the fact that they're mild steel is the only place that'd come in handy. Their draft system is elementary at best, and the last 28-40 I installed was creeping 40 degrees past setpoint with no load on it due to that cheesy ass flapper contraption. It was warm out, but that's beside the point. If it was doing it without a load, it's going to do it all the time and waste a lot of unnecessary fuel IMO. I checked out a brand new one and 2 already in place after I figured that out, and all 3 of those had the same constantly open intake passage. Pretty cheesy for a $9k boiler IMO
