Convert Gas Heaters

[BoilerControler]

Hello,

I have a customer who wants me to make his heaters a little bit more people friendly.
He manages a 65,000 sq ft light assembly environment that was once a warehouse environment with heat designed for warehouse.
There are 2 - 25' tall giant gas heaters along the eastern wall of the building with intake on the bottom and exhaust on the top about 15' apart from intake to exhaust.
When the heat is turned the blower runs constantly and the gas heat comes on intermittently. There are about 125 people in this room and when those heaters come on it is very loud, windy, and breezy. Papers are flying off of desks and everyone is complaining. Is there any practical solution to making these mega heaters a bit more personnel friendly?

Thanks for the help.

Jim

Sounds like the t'stat is controlling the fans. If that is the case, use a reverse acting fan switch (like on a residential furnace). Then just set the stat to not control the fan during heating and your golden.

didnt like the answers on this question on the other thread huh?

!25 people have to inhale flue gas from a direct fire unit made for a warehouse operation where the temp was probably set a lot lower than it would be for an assembly activity.

Does that about sum things up? You need to step back and figure out what's going on here. And Oh by the way I wonder what the CO/ CO2 readings are?

where in the post does it say its direct fired? it appears to be an air rotation unit, noisey & drafty. look into Cambrige Engineering units. theyre direct fired and do a fine job in this type of an enviroment.

Dont waste your time with cambridge. It is the same as using a unit heater. The reason for using an air rotation unit is to stop stratification which saves you lots of cash. Cambridge is the same. I had this argument with someone before and it is like talking to a wall.

I worked at a paper mill on a few cambridge units and they said we had this equipment installed because the rep said it would save them money compared to their unit heaters..... OH boy that company got hell. Anyway the units sat about 40' off the floor and at ground level 55 degrees and 40' off the floor 120 degrees!!! Tell me how that is efficient? Now compare that same scenario to when you have an air rotation unit and we will talk. Not trying to be an a$$

Also direct fired equipment will range from 0 ppm to 4 ppm for CO and .4 ppm NOX. Put a carbon monoxide and NOX sensor in the space and no problems. Seen a number of buildings setup this way.
