acid wash?

Bill Nye_2

You really want to do this? First you have to isolate the coil from the rest of the system. Cut in two valves, hot and cold, and then cut in two hose connections. Then you need a pump , 5 gallon pails, washing machine hoses. Wash it one way and then reverse direction and flush it the other way. Green and nast looking stuff will come out. Then flush it real good with clean water.

Don't get any on ya'. If you have to wash the outside of the coil, remove it from the boiler and immerse in a bucket of water and dilute acid. Use cold water and always dilute it, read the directions. If you go through all the trouble of removing the coil you might as well replace it with a new one. a lot easier and safer and it will work better. The acid just might eat a hole in the piping or coil. Rinse everything well when you are done. It will eat you skin.

Safety first

Wear gloves, wear goggles, don't get any on your skin or breathe any vapors. Read the directions and then read them again. If you don't feel comfortable doing it, don't do it. What is a submersion coil?

Safety is no problem but what of the procedure.

the coil in a part of a summer/winter boiler I thing you would call it a submersion coil. the coil is in the side of an old Am, Strd. boiler making domestic hot water in the summer.

I refuse to acid the coils. I replace them. Getting rid of the acid after you are through is a huge headache.

out with the old

pull the coil & replace it or condemn the coil and provide a gas fired hot water heater.

Thanks

Omigod!!

Tis brings back some old memories!!...Sidearm heaters....
We used to use Chloroben DE and pump thru the coils...Not the thing to do now,could turn your cellar into a Superfund site...replace,or put in a stand-alone HWH.

here is a how too,on many levels.

first install two no kinks ahead of two valves shut the valves attach a acid bath kit with washer hoses to the no kinks.let the machine run a half hour. hook up a wayne pump blast water thru it into a bucket. that dont work,

remove and take to a radiator shop and have them Boil the coil. and repair any leaks.

that dont work buy a new one bolt it up,that dont work snatch the boiler out and put a new one in with an indirect. good luck.

Every dang darn time I tried to "save some money" for a customer by agreeing to acid a coil, the coil either leaked immediately after, or it leaked within a month.
I will not do it anymore. Much better for the customer to sell an indirect and condemn the coil in place.

If you are doing it to an old Arcoliner be prepared to buy an alternate hot water maker. if you are going to remove the coil be prepared to buy a new boiler. respectfully the reasons being, you may put a hole in the coil or you may break stud off in the boiler. if the jacket on the boiler is copper or silver coloured with soft curves it is an arcoliner. isolate the "in" and the "out" pipes with valves then install to adapter tees on the afore mentioned pipes on the coil side of each. the tees will allow you to use two boiler drain valves to attatch the hoses to. buy an acid pump and use only NM-40 acid. many supply houses sell hercules sizzle for this you will most likley be overcome by the fumes long before the coil is clean. wear gloves, long sleeves and saftey goggles.

Have not used it on boiler coils but have used it on chiller heat exchangers. Seems to work very well. One gallon will disolve 2 pounds of minerals. It is biodegradable descaler and you don't have the headaches with disposal that you do with acids.

If you really want to do this. Make sure you have baking soda or some other alkaline product on hand to neutralize the acid.
Maybe you could flush the coil with vingar or lemon juice, try coke or pepsi both contain acid. Bringing dangerous chemicals in to a customers home is something I try to avoid. Best wishes J.Lockard
