"Dennis, combustion appliances do not put out any specific amount or range of CO (or CO/Hr). A very small amount (in the single digits) of CO may be given off with a new appliance, but it is often after they have operated for a while that the CO…"

"John,  of the byproducts listed,  the CO, NOx and H2O I suspect are the most important to consider.   For the unvented heaters used in a cold dry climate during the winter time -- probably adds just a portion of the H2O that would be…"

"Both were LP gas.  The more you test the more you find.   This after noon I saw a large office with a open flame of Nat Gas for looks - after it sooted up in flue was 2560 PPM CO but in office was 44 PPM CO with doors open plus dirt -…"

Unvented Gas Space Heaters – Continued Delays

On Saturday the ASHRAE committee that has been trying to consider a standard affecting unvented gas space heaters for over 10 years was again prevented from issuing proposed standard language for public review.Just so we are all on the same page, unvented gas space heaters dump 100% of their combustion products into the house. These products include NO2, CO2, CO, H2O, etc. None of these pollutants are good for human health when concentrated within a home. NO2 for example is a carcinogen that…See More

John Proctor commented on Eric Kjelshus's blog post Who among us tracks the accuracy of Manual J?
"Eric  It is doubtful that the fan motor is using more energy, the electrical use of PSC motors is nearly constant regardless of speed. What climate are you referring to? If it is a wet climate, then you need the latent removal and should…"

John Proctor commented on Eric Kjelshus's blog post Who among us tracks the accuracy of Manual J?
"Proctor Engineering has done many studies on Manual J vs. true load. The short answer is the sensible load is actually 2/3 of the Manual J 7 (note 7) estimated sensible load and Manual J8 calculates an even higher sensible load. The latent load…"
