Drolet ECO 65 with a Crosslink conversion kit

[Bioburner]

Mine was still operating without issues as of last fall. Still blending corn with pellets. Got smart and stay in South TX for winter.

 

[Love the Heat]

Mine is still working great, water leaving at 120F and returning at 100F.
Keeping the entire house warm at 72F.

What kind of circulations pump are you using?

 

[Love the Heat]

BumbleBee...pump running at 6.8GPM. My Fan is constantly running so the temperature holds the same at either -7C or -30C. Of course at -30C it runs longer on 4 before returning to idle (1) but my Thermostat handles it very well with a fluctuation of.5 degree. the temperature
stays a 72F with shorter or longer cycle at idle depending on outside temperature.

Can you get the temp up to 130 F and slow down the pump? This will give you a larger Delta from water entering and leaving.? This way you may extract more heat out of the stove heat exchanger.

How much pellets do you burn in a day doing that?

I could and I did brought it up to 140f with an aquastat running with the fan on the furnace at Off, I'm not sure
but I will check to see If I can run the pump at a lower number, but I think this is the lowest I can do with it. I didn't like it as I could feel a much bigger difference in temperature in the house during it's ON and OFF cycle.

Between 1 and 2 bag. colder it is more it burns, we don't seem to be able to win on that one. Basement and upstair (2500SQ/feet)
Set at 4 or 3 doesn't seem to make a difference, set at 4 it will run shorter cycle before turning back to idle(1).
I'm always amaze to see it going to idle when -30C outside.

2 bags of pellets over a day averages out to 26,000 btu/hr. Of input potential. Not output.

You stove max burn rate is 7.6lb/hour, and optimum efficiency is 80%, per specs. Which would be 48,000 btu/hr MAX output.

A 20°dt in water flow at 6.8 gpm is 65,000 btu/hr - IMO defying physics & your stoves potential & available fuel & coil heat transfer ability.

Something isn't adding up in the figures posted unless I really miss understood something in what was posted.

I'm Not sure either what your point is or that you don't understand.. The one thing I can add to my numbers is that it is not running
on 4 setting constantly, when the heat demand is met it turns to idle and depending on temperature sometimes it will be for 15-20 minutes. On idle the output water is at 100F...

BTW.. Have you had to change your lighter???? I have the first series #222 and they sent me the retrofit kit with a 300 watts lighter under a new burn pot and I haven't been successful at lighting it on without my help with a torch,,, just not enough heat in my opinion if I compare to the original 500watt with the vacuum pump.... Regards

Just that a 20dT flow at 6.8gpm would be impossible for a coil in a pellet stove to maintain. That would be 65,000 btu/hr, which is 35% more than the total heat output capacity of your stove at max burn.

So if I understood something in the numbers you posted - well, that would be what I am not understanding.

btu= delta T X 500 x GPM I agree wil maple something is off. I dont think you can get 20 temp across the core. I say 7-10 degrees max.
