Water treatment for OWB

[ngzcaz]

I've been reading a bit about the corrosion factor in OWB and while it may not
be a concern in the first several years, it certainly could be down the road. This could be particularly of concern for those who opted to run the OWB directly in the home oil boiler instead of using a heat exchanger. In NE Pa most oil burners have a hot water coil so no other h/w storage is required. Obviously the hot water in the coil never mixes with the hot water in the boiler.
I know this is not the preferred method but a LOT of guys in this area having been doing it w/ seemingly no problems for approx 6 years. Corrosion seems to occur when oxygen is induced in the water which would be the case since the OWB is vented to the atmosphere. I have seen water treatments that tout to stop this corrosion ( a quart to up to 200 gallons of water for approx $ 25 ) If that is true, seems to be cheap insurance not only for the OWB but for the oil burner in the home as well.
Anyone used this stuff ??

Everyone with a carbon steel OWB should be using it. I get mine from Woodmaster. My unit is 2 years old and when I drained it in the spring to change the water I got a good light and looked into the overfow pipe expecting to see red steel but I saw nothing but clean blue colored metal. Made a real believer of me in the treatments.

I use the Woodmaster brand also. The treatment is like gas stabilizer, it forms a film and keeps the oxygen out so no corrosion can occur. Very cheap insurance.

I also oil the firebox during the off season.

I do this as well. It makes a difference compared to those who don't. I use the CB brand for my stove, I would like to compare ingredients and prices between Woodmaster, CB and other brands.

Seems that both ash and creosote are rust accelerants and a little oil is the easy way to prevent corrosion in the firebox over the summer. I clean mine out best I can without making a career out of it and mix some engine oil and diesel and spray it with a garden sprayer. Takes about a pint. A person could plug the stack and keep it dry inside with some dessicant and due the same thing and be more politicaly correct (the reason the MFGs dont tell you to do it) But I could care less, the huggers pollute way more driving to their meetings than the pint of oil I burn once a year. Between using the proper chemical in the water and oiling the firebox my two year old unit looks like new, inside and out. Those with 304 stainless machines could probably just shut em down and forget them, mine is carbon.

After shoveling out the ashes I just used an old shop-vac to get the rest out, which worked very well btw. I used the less sophisticated method, a shop rag dipped in heavy oil and slopped around the lower half of the box. I used a can of WD-40 for the hard to reach spots

you mean your corrosion inhibitor film application device?

LOL, do you work for the government?

Woodmaster 4400 extra connections

Looks like heating season and the first fire in our furnace will be here soon. I was reading in the manual that one should either remove and plug the extra outlets on the back of the machine or insulate them. What are you folks doing if both sets are not being used?

Thanks!

I would really not like to know how cold it would have to get to freeze those valves being that close to 180 water but why take the chance? A scrap of fiberglass or even a discarded towel should provide protection to at least 150 below zero. I run two loops, mine are insulated for heat loss, not for freezing.

Access Panel

So, does the access panel stay on or left off considering the bottom being open? My Woodmaster is IN my woodshed and so is pretty well protected.
