Dickinson p9000 propane orifice

[knigh315]

I'm wondering if any one has tried to replace the p9000 orifice with the p12000 orifice, or just make the orifice slightly bigger? My unit works great at maintaining temps, but has a hard time bringing temps up. So I was thinking of either swapping out the orifice or slightly enlarging the hole to get slightly more BTU from my unit.

I'm heating a space that is 14x7.5x7 feet. And my unit sits about 1 foot from the ground. I had it higher but found it would heat the top portion and leave the floor really cold.

He, welcome to the world of thermal dynamics. When you are heating a cold boat you begin to realize what the teachers told us in school. I went thru these same wonderments when I moved on board 15 yrs ago in Southern New England. Heat does NOT sink. I have a Dickenson P12000 and the heat is not very efficient. I use it mainly for looks and ambience. The orifice is only one part of the gas supply, the last piece. I am not sure it will work, but tech support on mine was awesome. I hope you have the appropriate propane shut off solenoids, etc... I have 2 propane sniffers and a few CO monitors.

It has been a learning experience. I have used gas fitting liquid thread sealer on all my connections and have installed fire/carbon monoxide, and gas detectors.

The reason I went with the p9000 over the p12000 was the low propane usage when the unit is on low. For the most part, it does heat pretty well in milder conditions. I almost need to shut off the unit, but when it gets cold good luck without using an extra source of heat and then leave the unit on full blast. I think maybe Dickinson have over stretch it's capabilities on paper. I think the p9000 should be marketed as a stateroom heater.
