I have a basement fireplace... negative draft due to 2nd and 3rd flue... oil furnace and ist flr fireplace cause negative pressure. It pulls the air DOWN the basement chimney. Do you know anyone in...

Can anyone tell me who the manufacturer of this pellet insert is? Photos attached.

I'm looking for a pellet stove insert that will fit in my basement fireplace. It's 20 1/2" tall and 28.75" wide (front opening). It's 21" deep. Can anyone recommend an insert that will fit in this...

Bob, was it the Englander 25EP? I am looking at the new 25EPI but they require an opening of ~36" wide and my fireplace is only ~26" wide. The drawing looks like it would still fit but Englander says...

Yes, but the best way is to isolate the fireplace from the furnace. Burning outside air is better than burning conditioned air.

I'm looking for a pellet stove insert for my basement. I MUST have outside air intake because my oil furnace will suck the smoke from my fireplace back into the room. My fireplace will also suck its...

The efficiency of the burner is determined by O2% or CO2% and stack temperature. Overall efficiency must consider all the other stuff, but the burner efficiency is still a valid number.

You can install a smaller nozzle provided the stack temperature still exceeds 350 Deg F. Going from a .75 gph to a .60 gph is a fuel savings of 20%. The unit won't run any longer if the nozzle (heat...

The highest efficiency (lowest cost) is achieved by lowering the boiler temperatures (high and low) until it does not satisfy. The less propane you use, the more effificient it becomes. I have a...

I am planning on buying and installing a Comfort-aire ductless split heat pump. Great deal $$$$$! Any opinions on quality?

Bill,
I'm not sure what box I have but it's red in color and it looks almost round/cylindrical. All corners are radiused, almost round 9-9.5" dia and 15-16" deep. can i cover with kaowool...

I have a Smith Cast Iron Boiler (Westfield, MA) with a Beckett Model SR burner. 'SR' doesn't show up anywhere on the Carlin chart you sent. My burner box is 9" wide x 9.5" deep x 15" tall. I think...

Draft is good at -.04" and -.02" measured with Dwyer magnahelic. This boiler has always had low stack temp (350 degrees is acceptable, albeit at the low limit). I thought I said I went from hollow to...

I have a Beckett gun that is cemented (non-removable) into the front of my hydronic boiler. (I assume it's a coal conversion)? During my tuneup today I noticed the flame is impinging on the rear...

My advice is to choose the school with the quickest curriculum and job placement help. YOU WILL GET OUT OF ANY SCHOOL WHAT YOU PUT IN. Get working and learn the rest OTJ.

Thanks for the added info. A heat pump becomes more efficient as the difference between indoor and outdoor temperature gets smaller. I have a case where a rooftop heat pump is in a room where the ID...

Whoops! Sorry. We are a school. I am showing the students (and teachers) how a rooftop unit works. The room is 65 degrees. Surely that isn't too far out of heating spec.

I cleaned both coils (ID coil had a little dust). We found that the Goodman has two flow-check piston metering devices. ONe is 047 DIa, the other is .061 dia. Does anyone know what size they are...

You are correct: discharge is superheated so PT chart does not apply. I will check temperature drop/rise across indoor coil. It May be dirty!

We checked the metering device. MAYBE the drier is restricted...
