Re: [RE-wrenches] solar hot water penetration flashing

I saw a "Retrofit (Wrap-Around) Dektite" flashing in a recent Dynamic Fastener catalog just before reading this post. It looks like it would work for replacing a flashing around a continuous pipe. Randy Brooks Brooks Solar, Inc. Solar Power for People 140 Columbia View Chelan, WA 98816 509-682

We're using coolie caps for our installations at this point and of course they are a very robust solution. We typically make them in house. That said, Chemlink makes a product called DuraSil which is supposidly good up to 400F and compatible with copper: http://www.chemlinkinc.com/docs/datash

Re: [RE-wrenches] GT 3.0 FAILURES

We have about 100 or so GTs installed with about 10 failed units since 2007. In one interesting case we had one fail (smoked circuit board, blown AC fuse, the common failure mode). We replaced it and it failed again about two weeks later. We replaced that one and it failed about 3 months later. We

The coolie caps are really just regular (oversized) caps which have been punched out to snugly accommodate the pipe to be sealed. Tom Lane's book, Solar Hot Water Systems, Lessons Learned ..., addresses this sealing method and many more. AET Solar in Jacksonville, FL stocks this item as well as

Re: [RE-wrenches] solar hot water penetration flashing

This is an on-going problem, apparently. We were getting the coolie cap fittings from EFI but they got out of the solar business recently. Does anyone have a source for these now? Thanks in advance. -- Nicholas Ponzio NABCEP Certified Photovoltaic Installer Building Energy 1570 South Brownell
