This may have already been addressed but I installed the Ranco ETC-111000 Electronic Temperature Controller on my H2, at what temp do most people set theirs at and what differential setting?

[jackel440]

Mine has like a 5* differential,but it is not a ranco.I also have it set at 185*

most times it comes from the dealer at 180 off and as low as 160 on. some folks change them deoending on the time of year. myself i run 160 off 150 on as i don't use mixing valves and i am comfortable thinking than any one (including children) that put their hand under the tap will have time to realize it is hot and move thier hand before any burns take place.
some folks say when they lower the set temps that theyy burn less wood. i don't have any info on that to agree or disagree if it makes a difference nor have i tried it

 When I install a furnace I normally set it at 170 with a 10 degree differential. On my own furnace I normally run it at 170 when its cold and as low as 150 when its warmer. Every furnace is different, try yours at a number of different settings and see where it works the best.

running mine at 160 on/170 off.  Definitly takes a lot less wood but not sure of the amount

[lawrencep]

i run mine 150 off 140 on

[Bull]

I set it at 160 on and 170 off, works great

Have mine set 140 on 155 off. Usually lower it in summer when only heating DHW. Have tried different settings in past. Lower water temps do seem to burn less wood for me.

[tulenutn2o]

175f on, 180f off.

165 on 185 off with a hydro hot air system , any lower air coming out of vents just don't feel hot.

I've owned two owb's now and I seem to burn less wood and form much less tar and creosote by keeping both temps up on the high side. My primary combustion chamber stays cleaner as well as the secondary burn chamber and heat transfer tubes. Mine comes on at 177 and shuts off at 185. The refractory brick seems to maintain enough heat so that when the system calls for heat the smoke lights off within 30 seconds or less. Less smoke equals happier neighbors as well as very little smoke seeping through the cracks of my old two story house. I've played with many different combos over the years and higher is what I've found works best for a gasifier, with a small differential. My current furnace is a puny little Pro Series 100. It's amazing what that little fart can do on such a miserly little amount of wood.    Marty

I am running at 160 on/170 off, and it's working good, in this can't find any problem

150 on/158 off on mine.

CB installers put thermo bypass valves on the system that redirects the water back to the boiler if it's too cold. (Around 150F) Keep that in mind when setting the controller.

Our controller is set to 185F/175F.

That is just so there is not a huge difference in the return temperature at the boiler so it doesn't shock it. Nothing to do with the operating temperature setting.

Every stove is going to be a little different. If you are going to play around with the setting it is best to start out with it around 180 and then work your way down. If you start getting more creosote buildup or aren't getting enough heat at the house then you want to go back up a little. Dryer wood could run cooler without as much creosote problem.
