Steamaster Tablet

Very effective water treatment. More economical than liquids yet still convenient to use. Don't over condition the water or you will end up with foaming. I use half the dose specified and never have an issue.

We have an older boiler which was installed in the early 70's, so it has quite a bit of rust within. I have been teetering on whether I should spray it out and clean it or not (I don't want to cause any sudden problems). So I started looking into whether I should use chemicals - and while this is NOT a "cleaning" product, it has gotten rid of the layer of gunk which was floating in my sight glass. You'll see this throughout the treads: "Don't follow the instructions!" - it's all contingent on what size boiler you have. Package says 5-6 tablets, I only used 4, and even that seemed like it was overkill. I would have given this a 5 star rating, but I've only used them once so far.

Before I started using this product I was using Steam Clen by Comstar, then one day while re building a #67 McDonnell Miller Low water Cut Off i discover how good this product is. I placed the LWCO body and float in a bucket of hot water, I then dropped one tablet into the body of the LWCO and amazingly you can see the dirt scales and rust began falling off the inside of the valve body. Then I start using it on boiler, before I put tablet into the boiler (number of tablets depend on the btu of boiler) I would fired the boiler up just to get the water hot then apply tablets through the tapping for the pop safety valve. Initially, you can see the water color in the gauge glass changes to Purple/ Violet and it would changed (depending on how dirty the boiler is) to dark brown or rusty while the boiler is running. This color coding is very essential for it will let you know if you need to introduce more tablets. Usually, in about a week this chemical will work it way through the entire heating system when the boiler is operating. Then some of the dirty water can be drained from the boiler drain valve and the return line at the bottom of the Hartford Loop. It also seems like this product REDUCE water hammer( banging) in steam pipes according to some customers .

The tablet size was too large to drop into the relief valve hole, but a quick hit with a mallet solved the problem. I had a significant rust issue an a constantly dirty sight glass. Now the rust is gone and the sight glass is crystal clear.

I started using this product a few years ago and my boiler water has never been cleaner. I will never run straight water again. As others have said do not follow the instructions on the bottle. I run 2 tablets in a WM EG-45 which is on the high side but the system performs fine. Make sure your water is oil free and very clean before adding this product and check your PH afterwards.

I used these on my new steam boiler when it was installed in 2012, you only need one or maybe 1-1/2 tablets for a small boiler. I drained a little water from the boiler last week and it's as clean as it was when I added the tablets. Boilers are expensive, protect them.

Makes the water pretty. First winter using it. I've put it in 6 different boilers so far.

Highly regarded as both cleaner and PH water conditioner amongst steam folks! However most agree that the factory recommended dosages are way too high! As a cleaner: 2 tablets for a small boiler & 4 tablets for a large boiler is PLENTY to steam & flush! As a conditioner: 1 tablet for a small boiler & 2 tablets for a large boiler to leave in.
