The key to effective HPWH's is location--- It will need a space large
enough, or with sufficient thermal mass, to provide fairly constant temps
above 50+ *. Ideally 65+, but not above 100 or so.Also, humidity is a large
component of there efficiency factor--the more the better! We've p
t the
interface, leaving no bond, in our experience. But a little keresene or your
trusty can of penetrating oil is great for cleanup.
Caulk is a great tool, but selection of the appropriate type, and application
techniques is crucial. Experimentation will be most useful.

You can kill all those pop-ups manually in Windows by using the Task Manager
to end the process:
1) Press Ctrl and Alt and Delete at the same time
This brings up Task Manager
2) Go to the "Processes" tab
Click on the Mem Usage column to bring those items that consume the most system
resources
tracking adjustments and so it
can be set flat for windstorms--just for hurricane insurance here in the

We continue to spec them for those sites with good E to W solar window. With
