CO2 allowance for temperature

Wearb · 2015-02-19 18:04:17

Anyone know if any testing has been done to see if the CO2 allowance for temperature needs to be treated diferently for balanced flue set-ups. I ask this as the incoming air is heated a little by the outgoing exhaust gases. I know this is mostly academic, but I am curious about these things.

I wouldn't have thought so, as the humidity would remain relatively the same (but not sure)

We had this discussed at the end of some thread about a month back.

The MI,s are designed with an ambient temperature of 20°C. If setting up a boiler( with MI,s asking for 12% co2) at 0°C ambient air, then you would need to adjust to 11.2% co2.

A couple of the lads posted Riello charts that show adjustments needed at different temperatures.
