Yes is does. It's in the Reaction Chamber column. You can see in the graph that the fire gradually becomes more efficient with its use of oxygen. It's the only explanation since the BTU load does not change. Notice the water temp sloping upward while it's idling. It's going to hit 200 and shut off the combustion air in probably another hour or so.

The btu load does change...
If it’s 50 outside vs 0 outside, the latter is colder air passing through the baseboard or whatever is in the loop.

The air passing thru the baseboard is in the house. It's always between 60-65 degrees.hotblast1357 wrote: ↑Fri. Dec. 21, 2018 12:59 pmThe btu load does change...

Well maybe it gets down to 58 in the house when it's really cold out. It depends also if there are warm bodies home using lights, computers, tv's ECT lol

If the temp never changes inside you wouldn’t need a source of heat..

What I’m saying is, depending on the heat loss of the house, it’s going to have cooler air going through them.
Or does it just have more air going through them?
Something has to change because a house needs more BTU’s when it’s 0 outside than when it’s 50 outside.

Typically about 3-1/3% more heat energy (BTU) is required for each additional HDD to be overcome. But that is for systems that can keep up. For systems that can't keep up the HDD's are not being overcome and instead with each additional HDD experienced the house simply gets colder by one degree. For the latter case a steady state rate of energy demand is what is experienced.

So it all depends at what outside air temp does the system begin to fall short at, below that, yes nothing changes, but above it, it’s all dependent on temp change.

Imagine your house being heated by an electric heater that is just on constantly. The BTU output doesn't change. Same deal with this situation.

I don’t think this discussion will solve anything with this setup.
Is he ever going to fix anything or?

The hi temp cut off needs to be raised to like 210-215.

I don't think it can be raised. It's an open system, no pressure. It'll boil at around 208 degrees due to altitude.hotblast1357 wrote: ↑Fri. Dec. 21, 2018 6:41 pmThe hi temp cut off needs to be raised to like 210-215.
