So its almost time to think about firing the boiler up for the season; however, the current weather forecast does not agree and it looks like it wont be till November before its time to start it up. I have been running my 80gal electric WH all summer and it has cost me about $29/mo to run, much more cost effective than running the coal boiler over the summer. All in all, im happy with the switch to electric in the summer.
I had some time this weekend to get my coal vac in order. Im using 2" SCH40 conduit with a 3/4" air bypass. I was pleasantly surprised how well it actually worked. After a few tweaks here and there it is working nicely. I think there is still room for improvement as i would like to maximize the 'feed rate' into the hopper without collapsing the barrel because as of right now it takes about 10ish min to move about 10gal of coal. I am going to try and reduce the bypass air a little to see if i can increase the suction some and see what happens. *Tried posting a short video of the suction but the forum does not like it for some reason** Ideally i would like to try to get the transfer to about 5min if possible.
I need to pick up a toilet flange for the bottom of the barrel and add some lateral support to the frame.
I also tried putting a dust deputy between the vac and the drum and that killed the performance reducing the suction too much. I will probably roll with the dust bag on the filter instead.
