Title: Temperature settings
Post by: schoppy on November 27, 2018, 11:16:29 PM
Hey guys question for you. I have a friend who has a CB gasser. He says he raised his operating water temp settings from 180/160 to 185/170 to help eliminate moisture in his primary combustion chamber.

Have any of you guys done or heard of people doing this on CB or any brand gassers? I get condensation/creosote on the inside of mine especially during light load times. Seems like you'll use more wood if you raise the temps also.

Because I have all baseboard emitters, I run my temps at 190/180.  I want all the heat I can get at the emitters.  I have the new CB Edge 550 that's been warming my house for about a month and I haven't seen a measurable up tick in wood usage at all.  Roger

I'm running my new 750 Edge HD at 185 as well and have played with operating at different set points  from 175 up to 190 and notice no difference in wood usage. I agree that higher operation temps reduce creosote buildup in the firebox. My thinking is that a burn cycle brings the water up 10 degrees regardless if from 165-175 or 175-185. The burn cycle seems to take about the same time and the urathane insulation keeps it there until the exchangers in my house/garage pull the water temp down for the next burn cycle.

I have a P&M 250 and I run it 190/180.  I don't think it really uses any more wood and my theory is that higher temps will reduce the amount of oxygen in my water and anything to keep the chambers drier is a good thing.

The only drawback I have noticed is increased evaporation.  I need to top it up a few more times a winter.

Appreciate the responses. How about any Heatmaster gasser owners, have any of you guys tried higher operating temps and if so why and what results have you seen?

Running 170/190 on mine just to keep up with the shop a little better. haven’t noticed any real increase in wood consumption. All Logstor for underground line.

Have you ever tripped the high limit? Seems like that is getting pretty close to it.

I was just wondering what the high limit is RSI?

Does the higher settings reduce moisture in the primary chamber mlappin (especially in lighter load times)?

I think it is 195.

I've found letting it burn down to a glowing coal bed does wonders for creosote/moisture.

I've found this to be true also. Once the wood has burned down, them coals radiate a lot of heat out into the firebox.

Ditto on the coals also. I load my G200 twice a day and getting the hang of matching the wood amount to the temperature load is the trick to ending up with that good coal bed every 12 hours or so.
