Garn Biocide?

[Swamp Yankee]

Hi,
My neighbor with a Garn says that they now recommend the use of a biocide in the boiler to prevent bacterial corrosion, but defers to "your water chemistry expert" to recommend one.

My manual (2007) states to run the boiler once a month in the off-season to kill off any bacteria. We've been doing this religiously but would rather not... with all the politcal b/s surrounding boilers in town, we prefer to be selective when we burn in the summer...picking rainy nights just in case the OWB police are sniffing around the neighborhood.

Anyone familiar with 'biocides' and have used an appropriate product? Any drawbacks to using this vs just keep burning once a month?

Thanks!

I don't think that's 100% correct. I suggest you do one of two things. Post you question on Garn's forum (www.garn.com) and/or PM me for a phone contact for the company who does Garns treatment program. He knows what he's talking about. From my limited experience and knowledge of bacterial corrosion, it's not all that common.
