Hi Gang.
I took advantage of the mild weather we are having here and filled my 1000 gallon storage tanks. The first burn on my new Econoburn EBW200 was today. I have to make sure I get the tanks heated up before it turns cold again
My first burn was only about half a load as I was a little nervous. The boiler only reached a156 degrees. I initiated another burn soon after the first with a larger load of wood. This time it got up to 163. The tops of my storage tanks are at about 140, but much less at the bottom. I thought it would get hotter as I had the boiler target set at 170. The wood I was using was seasoned two seasons and my manometer was reading perfect draft at .03.
I am suspecting that my problem is with my Caleffi 281 mixing/boiler protection valve. Even when I had the boiler up to 160 and the input in the top of the valve was reading 160, the water going back to my boiler only ever reached 105. I have attached a poor picture but you get the idea. I think the valve is suppose to recycle all water back to the boiler until the return water reaches 140. Only then will it pump to storage. In the picture my boiler is to the right and storage to the left.
I removed the small packing screw from inside the pump before I installed it so that is not the problem. If anyone else is using this pump can you tell me if I am missing something.
