Running steam boiler with Rhomar Hydrosolv-9150

I am going to try some Hydrosolv-9150 since I have been unable to eliminate my whistling vents via skimming.

The instructions suggest to run the boiler for two to four hours at normal temperature and then flushing the boiler. Everything I have read in Dan's books say to never generate steam when a cleaner is in the water, since you are likely to open up a leak in a joint. This kind of scares me.

Advice?

from what i've seen,

when water boilers, the steam is pure water..

Can anyone else comment? Is it true that a steam boiler with cleaner in it is OK to let steam for a few hours?

Mark Hunt

Yup


In fact, I let the Hydro-Solve run for a few days on one system.

The boiler was piped in copper and the skim tap was never installed. We replaced the copper piping with steel and added the skim tap. After the re-pipe, we added Hydro-Solve and ran the boiler just below steaming for a couple hours. Drained everything, and re-filled. Repeat step one. Re-filled and skimmed. Added more Hydro-Solve and left for a couple days. Returned and drained everything. Added new water and skimmed again.

The system was as silent as a church mouse last heating season and now the homeowner will not let anyone else touch his steam system.

I can say this, I had never heard a system surge like this one. Sounded like a washing machine when it started to steam. All of the flux was washed back into the boiler and no amount of skimming would have removed it even if the installing contractor had bothered to install a skim tap. Hydro-Solve got it out and now it runs silent.

The folks at Rhomar have a heck of a product.

I'm hooked.

I'm thinking that the reason...

is that the chemicals could get further up into the system and bust loose a WHOLE bunch more crap than you would believe.

Be prepared for a mud slide.

Also, someone needs to come out with a reverse acting non electric TRV that can be hooked up to the skim tapping on a boiler that would maintain a flow of 180 degree F water while skimming. The valve operator would control the flow of water coming into the system. IT would be extremely proportional and would guarantee optimal flushing action.

Someone? If not non electric, how about a proportional electric valve.

Anyone?

Once done, you take the components with you to the next job.

So it sounds like I should run the boiler, but not to the steaming point?

While I have skimmed my new boiler around six or seven times, at what rate should I be skimming, in gallons per minute? I have a 1-inch hose fitting connected to the skim tap, so I can set the feed rate and sit and read a magazine while it skims.
I haven't seen anywhere someone instructing what rate the skim water should run... 1/2-gallon a minute? More? Less?

How long should I run the water before draining the boiler and refilling again?

Let it steam


No problem letting it steam.

Skim at a trickle. I can't put a GPM number to that, but skimming is taking what is at the very top of the water. If you get a full flow out of the skim tap, you're water line is above that point. You are draining the water BELOW the junk that floats on top. You want the water to be just spilling out of the skim tap.

listen to Mark for crying out loud..

i'm putting some in a steam boiler tomorrow and have no intention what so ever of going back before a couple of days to clean it out...why cause it says in the instructions to leave it in for days OR weeks on an old boiler..

In talking to George about 9150,

It has components that vaporize and are carried out into the system to help clean the system. If I want to limit system cleaning, I use 9100(?) hot water system cleaner. It does seem to get caried out into the system somewhat,probably through wet steam but apparently less so. Both seem to make the water line bounce alot, but they do the job quite nicely.

I just placed an order for the Rhomar cleaner and treatment. Should receive it Tuesday. I'm hoping that this will finally stop my whistling radiator vents.
